What about time?

In this 11 minute presentation Art Chadwick, from Southwestern Adventist University, discusses radiometric dating. Chadwick was very forthright:

I guess one of the problems that none of us like to look at is a problem we don’t have the answer to. And yet in science it is always considered a good thing not to have all the answers. We as lay people like to think we have all the answers to everything that has to do with the Bible. But as scientists we don’t want all the answers we want unanswered questions so that we can do science because that’s what scientists do. So take heart because we don’t have all the answers and probably won’t have as long as we’re on this planet.

In Chadwick’s opinion, “radiometric dating… is an unsolved problem….” He proceeds to suggest some other possibilities other than radiometric dating in regard to time. Many of the other scientists presented findings that appeared to contradict ages calculated from radiometric dating.

Specific Problems with K-Ar and Ar-Ar Dating (Part 4 of 15)

By Sean Pitman M.D.

Specific Problems with K-Ar and Ar-Ar Dating is 4 of 15 parts to Radiometric Dating Methods.

In the first place, I am not primarily concerned with dating meteorites, or Precambrian rocks. What I am more interested in is the fossil-bearing geologic column of Cambrian and later “ages”.    Since 40K/40Ar and 40Ar/39Ar dating are most commonly used to “prove” the ancient age of many life forms, I will discuss these dating methods specifically in more detail and show that they, along with the other common methods of isotope dating, are to be highly questioned.  I will begin this section with a short discussion from Andrew Snelling, an associate professor of geology in El Cajon, California.

According to the assumptions foundational to potassium-argon (K-Ar) and argon-argon (Ar-Ar) dating of rocks, there should not be any daughter radiogenic argon (40Ar*) in rocks when they form. When measured, all 40Ar* in a rock is assumed to have been produced by in situ radioactive decay of 40K within the rock since it formed. However, it is well established that volcanic rocks (e.g. basalt) contain excess 40Ar*, that is, 40Ar which cannot be attributed to either atmospheric contamination or in situ radioactive decay of 40K. This excess 40Ar* represents primordial Ar carried from source areas in the earth’s mantle by the parent magmas, is inherited by the resultant volcanic rocks, and thus has no age significance.

However, are all other rocks in the earth’s crust also susceptible to “contamination” by excess 40Ar* emanating from the mantle? If so, then the K-Ar and Ar-Ar “dating” of crustal rocks would be similarly questionable.

When muscovite (a common mineral in crustal rocks) is heated to 740°-860°C under high Ar pressures for periods of 3 to 10.5 hours it absorbs significant quantities of Ar, producing K-Ar “ages” of up to 5 billion years, and the absorbed Ar is indistinguishable from radiogenic argon (40Ar*). In other experiments muscovite was synthesized from a colloidal gel under similar temperatures and Ar pressures, the resultant muscovite retaining up to 0.5 wt% Ar at 640°C and a vapor pressure of 4,000 atmospheres. This is approximately 2,500 times as much Ar as is found in natural muscovite. Thus under certain conditions Ar can be incorporated into minerals which are supposed to exclude Ar when they crystallize.

Because it is known that excess 40Ar* is carried from the mantle by plumes of mafic magmas up into the earth’s crust, it is equally likely that much of the excess 40Ar* in crustal rocks could be primordial 40Ar. Thus, we have no way of knowing if any of the 40Ar* measured in crustal rocks has any age significance. Additional to the primordial 40Ar from the mantle is 40Ar* released from minerals and rocks during diagenesis and metamorphism, so that there is continual migration and circulation of both primordial 40Ar and 40Ar* in the crust which is reflected in their presence in CO2-rich natural gases. Therefore, when samples of crustal rocks are analyzed for K-Ar and Ar-Ar “dating,” one can never be sure that whatever 40Ar* is in the rocks is from in situ radioactive decay of 40K since their formation, or if some or all of it came from the mantle or from other crustal rocks and minerals. Thus all K-Ar and Ar-Ar “dates” of crustal rocks are questionable, as well as fossil “dates” calibrated by them.19

In summary, many scientists assume that since argon is a gas, all of it should have escaped from the lava before it cooled. Therefore, all the 40Ar in the rock should be the result of decay from potassium. Based on the measured potassium, argon, and the decay rate, they calculate an age. That is why it does not matter how long the magma was in the volcano before it erupted. They believe that when the volcano erupts, all the 40Ar escapes, and the atomic clock gets reset to zero.

If all the argon escaped from hot lava of volcanoes that erupted long ago, then all the argon should escape from the hot lava of volcanoes that erupt in modern times too. But modern lava does have 40Ar in it. This is known as the “excess argon problem”.  Scientists are well aware of this problem and use various calibration methods to “correct” for this problem.  However, how are these calibration methods established?  Upon what basis are they validated?

Calibration of the Argon-Argon Dating Method

Regarding the Ar/Ar dating method in particular, it is an interesting and seems to me to be a common argument that the problems inherent in K/Ar dating are overcome by the step-heating method of Ar/Ar dating.  What most people don’t realize, or at least don’t discuss, is that Ar/Ar method is not an absolute dating method. Let me emphasize again that this dating method is a relative dating method.  In other words, it must be calibrated relative to a different dating method before it can be used to date materials relative to that other dating method.

Because this (primary) standard ultimately cannot be determined by 40Ar/39Ar, it must be first determined by another isotopic dating method. The method most commonly used to date the primary standard is the conventional K/Ar technique. . . Once an accurate and precise age is determined for the primary standard, other minerals can be dated relative to it by the 40Ar/39Ar method. These secondary minerals are often more convenient to date by the 40Ar/39Ar technique (e.g. sanidine). However, while it is often easy to determine the age of the primary standard by the K/Ar method, it is difficult for different dating laboratories to agree on the final age. Likewise . . . the K/Ar ages are not always reproducible. This imprecision (and inaccuracy) is transferred to the secondary minerals used daily by the 40Ar/39Ar technique.” 49 ( Link )

Step heating does not overcome this inherent reliance of Ar/Ar dating on calibration with K/Ar or other dating methods.  So, whatever problems exist in the method used for calibration will be passed on to the Ar/Ar dating method as well.  This same problem exists for all other relative radiometric dating techniques.  In addition, there are other problems with Ar/Ar dating such as the uncertainty of the decay constants for 40K and 39Ar recoil.

Fission Track Dating

FissionTracksFission track dating is a radioisotopic dating method that depends on the tendency of uranium (Uranium-238) to undergo spontaneous fission as well as the usual decay process. The large amount of energy released in the fission process ejects the two nuclear fragments into the surrounding material, causing damage paths called fission tracks. The number of these tracks, generally 10-20 µ in length, is a function of the initial uranium content of the sample and of time. These tracks can be made visible under light microscopy by etching with an acid solution so they can then be counted.

The usefulness of this as a dating technique stems from the tendency of some materials to lose their fission-track records when heated, thus producing samples that contain fission-tracks produced since they last cooled down. The useful age range of this technique is thought to range from 100 years to 100 million years before present (BP), although error estimates are difficult to assess and rarely given. Generally it is thought to be most useful for dating in the window between 30,000 and 100,000 years BP.

A problem with fission-track dating is that the rates of spontaneous fission are very slow, requiring the presence of a significant amount of uranium in a sample to produce useful numbers of tracks over time. Additionally, variations in uranium content within a sample can lead to large variations in fission track counts in different sections of the same sample.42

Because of such potential errors, most forms of fission track dating use a form of calibration or “comparison of spontaneous and induced fission track density against a standard of known age. The principle involved is no different from that used in many methods of analytical chemistry, where comparison to a standard eliminates some of the more poorly controlled variables. In the zeta method, the dose, cross section, and spontaneous fission decay constant, and uranium isotope ratio are combined into a single constant.” 43

Of course, this means that the fission track dating method is not an independent method of radiometric dating, but is dependent upon the reliability of other dating methods.  The reason for this is also at least partly due to the fact that the actual rate of fission track production. Some experts suggest using a rate constant of 6.85×10-17 yr-1 while others recommend using a rate of 8.46×10-17 yr-1 (G. A. Wagner, Letters to Nature, June 16, 1977).  This difference might not seem like much, but when it comes to dates of over one or two million years, this difference amounts to about 25-30% in the estimated age value. In other words, the actual rate of fission track production isn’t really known, nor is it known if this rate can be affected by various concentrations of U238 or other physical factors.  For example, all fission reactions produce neutrons. What happens if fission from some other radioactive element, like U235 or some other radioisotope, produces tracks?  Might not these trackways be easily confused with those created by fission of U238?

The human element is also important here. Fission trackways have to be manually counted.  This is problematic since interpreting what is and what is not a true trackway isn’t easy.  Geologists themselves recognize the problem of mistaking non-trackway imperfections as fission tracks.  ”Microlites and vesicles in the glass etch out in much the same way as tracks.”45 Of course, there are ways to avoid some of these potential pitfalls.  For example, it is recommended that one choose samples with as few vesicles and microlites as possible. But, how is one to do this if they are so easily confused with true trackways? Fortunately, there are a few other “hints”. True tracks are straight, never curved. They also tend to show characteristic ends that demonstrate “younging” of the etched track. True tracks are thought to form randomly and have a random orientation.  Therefore, trackways that show a distribution pattern tend not to be trusted as being “true”.  Certain color and size patterns within a certain range are also used as helpful hints.  Yet, even with all these hints in place, it has been shown that different people count the same trackways differently – up to 20% differently.44 Add up the human error with the error of fission track rate and we are suddenly up to a range of error of 50% or so.

This is yet another reason why calibration with other dating techniques is used in fission track dating. It just isn’t very reliable or accurate by itself.  And, it gets even worse. Fairly recently, Raymond Jonckheere and Gunther Wagner (American Minerologist, 2000) published results showing that there are two kinds of real fission trackways that had “not been identified previously.”  The first type of trackway identified is a “stable” track and the second type is produced through fluid inclusions. As it turns out, the “stable tracks do not shorten significantly even when heated to temperatures well above those normally sufficient for complete annealing of fission tracks.”  Of course, this means that the “age” of the sample would not represent the time since the last thermal episode as previously thought.  The tracks through fluid are also interesting. They are “excessively long”.  This is because a fission fragment traveling through a fluid inclusion does so without appreciable energy loss. Such features, if undetected, “can distort the temperature-time paths constructed on the basis of confined fission-track-length measurements.” Again, the authors propose measures to avoid such pitfalls, but this just adds to the complexity of this dating “method” and calls into question the dates obtained before the publication of this paper (i.e., 2000).46

These problems have resulted in several interesting contradictions, despite calibration.  For example, Naeser and Fleischer (Harvard University) showed that, depending upon the calibration method chosen, the calculated age of a given rock (from Cerro de Mercado, Mexico in this case) could be different from each other by a factor of “sixty or more” – - “which give geologically unreasonable ages.  In addition, published data concerning the length of fission tracks and the annealing of minerals imply that the basic assumptions used in an alternative procedure, the length reduction-correction method, are also invalid for many crystal types and must be approached with caution unless individually justified for a particular mineral.” [emphasis added] 47  Now that’s pretty significant – being off by a factor of sixty or more?!  No wonder the authors recommend only going with results that do not provide “geologically unreasonable ages.”

Tektites

Tectites1

AustraliteAnother example of this sort of aberrancy comes in the form of glass globs known as “tektites”.  Tektites are thought to be produced when a meteor impacts the Earth.  When the massive impact creates a lot of heat, which melts the rocks of the Earth and send them hurtling through the atmosphere at incredible speed.  As these fragments travel through the atmosphere, they become superheated and malleable as they melt to a read-hot glow, and are formed and shaped as they fly along.  It is thought that the date of the impact can be dated by using various radiometric dating methods to date the tektites. For example, Australian tektites (known as australites) show K-Ar and fission track ages clustering around 700,000 years.  The problem is that their stratigraphic ages show a far different picture.

Tectites2Edmund Gill, of the National Museum of Victoria, Melbourne, while working the Port Campbell area of western Victoria uncovered 14 australite samples in situ above the hardpan soil zone. This zone had been previously dated by the radiocarbon method at seven locales, the oldest dating at only 7,300 radiocarbon years (Gill 1965). Charcoal from the same level as that containing specimen 9 yielded a radiocarbon age of 5,700 years. The possibility of transport from an older source area was investigated and ruled out. Since the “Port Campbell australites include the best preserved tektites in the world … any movement of the australites that has occurred … has been gentle and has not covered a great distance” (Gill 1965). Aboriginal implements have been discovered in association with the australites. A fission-track age of 800,000 years and a K-Ar age of 610,000 years for these same australites unavoidably clashes with the obvious stratigraphic and archaeological interpretation of just a few thousand years.

Hence, geological evidence from the Australian mainland is at variance, both as to infall frequency and age, with K-Ar and fission-track dating” (Lovering et al. 1972). Commenting on the above findings by Lovering and his associates, the editors of the book, Tektites, state that, “in this paper they have built an incontrovertible case for the geologically young age of australite arrival on earth (Barnes and Barnes 1973, p. 214).

This is problematic.  The argument that various radiometric dating methods agree with each other isn’t necessarily true. Here we have the K-Ar and fission track dating methods agreeing with each other, but disagreeing dramatically with the radiocarbon and historical dating methods.  These findings suggest that, at least as far as tektites are concerned, the complete loss of 40Ar (and therefore the resetting of the radiometric clock) may not be valid (Clark et al. 1966). It has also been shown that different parts of the same tektite have significantly different K-Ar ages (McDougall and Lovering, 1969).  This finding suggests a real disconnect when it comes to the reliability of at least two of the most commonly used radiometric dating techniques.48

In short, it seems like fission track dating is tenuous a best – even when given every benefit of the doubt.  It is just too subjective and too open to pitfalls in interpretation to be used as any sort of independent measure of estimating elapsed time.

IN MEMORIAM

This article is another excellent contribution by Dr. Gerhard Hasel, who for many years served as an editorial consultant to Origins. Dr. Hasel lost his life in a traffic accident the day before he was to make a public presentation of this article. It thus represents one of his last — if not his final — intellectual contributions to our understanding of the Bible. Unfortunately, he did not have a chance to review the final copy. Our appreciation goes to Michael Hasel for his assistance. Warren H. Johns offered constructive criticism from a bibliographic viewpoint.

We wish to dedicate this article to Dr. Hasel’s memory, with special thanks and fond memories. We are also grateful for his earlier contributions to Origins and for the multitude of other thoroughly researched publications that have come from his pen. His careful scholarship and unwavering faith in the truthfulness of God’s word has helped to strengthen the faith of many in the Bible.

WHAT THIS ARTICLE IS ABOUT

The question of whether the six days of creation were actual 24-hour periods of time or only symbolic representations of millions of years has been debated for centuries. During the past century and a half, with recognition of the theory of evolution and its vast eons of time, the matter has been under more serious scrutiny.

The following article is a thorough review of this issue. The historical background and the literary nature of the creation account are discussed in detail and related to a variety of contemporary interpretations. The author concludes with ten considerations which support the concept of a literal creation week with seven consecutive, twenty-four-hour days.

I. INTRODUCTION

The increased focus of recent decades on creationism, “creation-science,”1 “origin science,”2 and “theistic science”3 has created a climate in which old questions are raised anew with specific focus and additional sophistication. One of those questions concerns the meaning of the term “day” in Genesis 1:1 – 2:3.

The nature of the Genesis account of creation with its six “days” (Genesis 1:5-31) followed by the “seventh day” (Genesis 2:2-3) is of special interest, since it is customarily understood to mean a short time of one week. This short time in the creation account is under debate on the basis of the current naturalistic theory of evolution. The contrast is between the short time of the creation account and the long ages demanded by naturalistic evolution.

This paper will seek to accomplish several interrelated tasks: 1) to provide some methodological observations with a brief history of interpretation; 2) to cite representative recent published opinions suggesting that the “days” of creation are long epochs or periods of time and not literal twenty-four hour days; 3) to present the data in Genesis 1 in relationship with other data found in the Old Testament; and 4) to apply to the data of Genesis 1 the standard linguistic and semantic investigations requisite in sound scholarship based on the best current knowledge.

II. METHODOLOGICAL OBSERVATIONS AND THE HISTORY OF INTERPRETATION

A knowledge of some aspects in the history of interpretation of the “days” of creation in Genesis 1 may prove to be helpful from the perspective of methodology for interpretation. Historical information assists the modern interpreter to recognize that it is incorrect to suggest that only since the publication of Charles Darwin’s epochal work, On the Origin of Species (1859), the Genesis creation “days” were transposed into non-literal periods of time. Earlier extra-biblical considerations led interpreters to depart from the literal meaning of creation “days.”

1. Some Medieval Understandings of Creation “Days”

The Alexandrian church father Origen (ca. A.D. 185 – ca. 254), an accomplished practitioner and defender of the allegorical method of interpretation,4 is credited with being the first to understand the creation “days” in an allegorical and non-literal manner.5

Augustine (A.D. 354 – 430), the most famous of the Latin Fathers, followed Origen in arguing that the creation “days” are to be understood allegorically, rather than literally.6Augustine is understood to teach that God created the world in a single flash of a moment.

At this point it seems appropriate to reflect on some methodological matters. Neither Augustine nor Origen had any evolutionary concept in mind. They took the creation “days” as non-literal, standing for something else, because it was philosophically mandatory to assign to God creation activity which was unrelated to human time. Since the “days” of creation are related to God, it was argued, these “days” have to be representative of philosophical notions associated with God taken from their philosophical perspectives.

In Greek philosophy God is timeless. Since the creation “days” are part of divine activity, it was assumed that they also should be understood in a timeless sense. The thinking of Origen and Augustine was influenced by Greek philosophy, not by scientific speculations, which led to a reinterpretation of the creation “days.”

What this approach has in common with modern attempts, which also take the creation “days” to mean something other than what the face value of the terminology seems to suggest, is that both are based on influences from outside the biblical text itself. Medieval theologians, who took the creation “days” to be non-literal, based it on non-biblical, pagan philosophical modes of thinking.

Today there is another influence from outside the biblical text that leads interpreters to change what seems to be the plain meaning of “days.” At present it is a naturalistically based scientific hypothesis, the modern theory of evolution, which provides the impetus for such changes.

The thinking of medieval Catholic theologians was influenced by the Alexandrian allegorical method of interpretation. The fourfold sense of Scripture was adopted in medieval times7 and is still supported in current official Roman Catholicism.8 The three non-literal meanings of the fourfold sense of Scripture (i.e., allegory, anagogy, tropology) carried the day and held primary importance for over a millennium in Christendom, providing the hermeneutical means for the reinterpretation of the literal sense of the creation “days.”

2. Reformation Understanding of Creation “Days”

The sixteenth-century Reformers agreed that the fourfold sense of Scripture compromised the literal sense of the Bible, making its authority for faith and life null and void. They insisted that the single, true sense of Scripture is the literal sense, the plain meaning of the text.

One of the major achievements of the Protestant Reformation is the return to Scripture. This meant that Scripture is in no need of an external key for interpretation — whether that key be the Pope, the church councils, philosophy, or any other human authority. Scripture’s clarity and perspicuity became the norm of the day; its reading from within its own context was paramount. External meaning must not be superimposed on it, as had been the practice under medieval Catholicism. The Bible was to be read in its literal and grammatical sense.9

Martin Luther, accordingly, argued for the literal interpretation of the creation account: “We assert that Moses spoke in the literal sense, not allegorically or figuratively, i.e., that the world, with all its creatures, was created within six days, as the words read.”10 The other Reformers understood the creation “days” in the same way.

This literal and grammatical interpretation, known in the history of hermeneutics as the historical-grammatical method, was the norm for biblical interpretation more or less into the nineteenth century.11

3. Changes Under the Influence of Modernism

As the concept of long time periods made its way into the understanding of Earth’;s origins in the wake of the publications of James Hutton (1726-1797) and Charles Lyell (1797-1875), some Christian concordist interpreters started to reinterpret the Genesis “days” of creation in a non-literal manner. The impetus for this was not found in the Bible itself but in the new world view which was being developed on the basis of uniformitarianism and its concomitant understanding of origins which demanded long periods of time.

The understanding of the creation “days” as “days of restoration,”12 “days of revelation,”13 aside from taking a “day” for an “age” (”day-age” theory) or an epoch/era14 goes back to this time and the changes in time frames required by the new geology. The approach of a non-literal reinterpretation of “days” was typical of concordists who had accepted long ages for the origin of Earth.15 In view of these developments, it is unavoidable to conclude that external influences exerted by a new understanding of geological ages became the catalyst for the reinterpretation of the “days” of creation.

4. Recent Changes in Interpretation Among Broad Concordists

Broad concordists of the last ten years are increasingly attempting to interpret the “days” in the Genesis creation account in non-literal ways, in order to bring about harmony between the long ages called for by the evolutionary theory and the time implications of the biblical record of divine creation in Genesis 1.

It is an acknowledged fact that the long and checkered history of the relation between science and Scripture has had an impact on the present understanding of the Bible.16The shift from the Ptolemaic world view to the Copernican one is probably the most celebrated example.17

The non-Christian Ptolemaic world view had been adopted by Christian medieval theologians both as the correct Christian and biblical view of Earth. Earth was conceived as the center of the solar system, and often of the universe. It became a first-class dilemma when the heliocentric Copernican world view became prominent and seemingly irrefutable.

From a methodological point of view the interpretational model at work by the scientist as interpreter of data observed in nature will predetermine to a large degree the outcome of the enterprise itself, as well as the meaning of data derived from non-natural sources, including the Bible. It is generally recognized that “scientific theories do affect biblical interpretation at least to the extent that they become the occasion for reassessing the interpretation of a few passages (Genesis 1-2; 6-8).”18 The decisive question which emerges is whether the reassessment becomes a superimposition of a meaning on the biblical text on the part of concordists and others — a meaning which is alien to the meaning found in Scripture within its own context.

At least two major options seem to present themselves: 1) A reassessment on the basis of “scientific” conclusions could lead to an interpretation of biblical texts which is permitted within the framework of the context and intention of the totality of Scripture. In such a case the reassessment does not do violence to the internal norms of cohesion and unity of Scripture. 2) The reassessment of a biblical text could likewise lead to a conclusion regarding the specific meaning of a given biblical text or a biblical passage which does not agree with what a current scientific hypothesis holds. For those who accept full biblical authority this should lead to a reassessment of the conclusion(s) drawn from the interpretation of data in nature by the scientist. The latter, in turn, may affect the scientific theory, or science broadly perceived, “at the very least by leading us to reassess whether all the conclusions drawn from a scientific theory are warranted, or in some cases to ask whether the theory as a whole is suspect.”19

5. The Inherent Authority of Scripture

Some have taken the stance that a scientific theory, by its very nature and the breadth of its acceptance, has priority over Scripture.20 It is far beyond the confines of this paper to unfold the complexity of this question. Suffice it to say that if Scripture is understood to be the result of divine revelation and written under inspiration, it would have a dimension of authority not found in the so-called book of nature. Based on that higher dimension of authority, Scripture can assist in interpretation of the book of nature, providing a more comprehensive model of interpretation than might be expected from a purely naturalistic model.

Scripture, if it is to maintain its own integrity, can hardly be interpreted in such a way as to be accommodated time and again to any kind of interpretation derived from science, sociology, history, etc. Scripture, based on its own nature and authority, has its own integrity of meaning and its inherent truth claims. They emerge ever more clearly on the basis of a careful study of the Bible with sound methods of interpretation which are in harmony with and rooted in the testimony of Scripture itself. This implies that Scripture’s; authority resides in itself; it is based in revelation and grounded in inspiration.

The self-sufficiency of Scripture of which we have spoken does not mean that any question raised from other areas of investigation such as science, history, sociology and so on cannot be discussed with reference to Scripture. But there is a vast difference between asking new questions of Scripture and superimposing meaning on Scripture.

III. FIGURATIVE INTERPRETATIONS OF THE CREATION “DAYS”

1. Representative Arguments for Long Ages

The clearly stated purpose of current attempts to interpret the “days” of Genesis 1 in terms other than face value is often quite clearly stated. A few citations from respected scholars will speak for themselves.

John C. L. Gibson, a British scholar, argues that Genesis 1 is to be taken as a “metaphor,”21 “story,” or “parable,”22 and not as a straightforward record of events of creation. He writes in his 1981 Genesis commentary as follows:

… if we understand ‘day’ as equivalent to ‘epoch’ or ‘era’, we can bring the sequence of Creation in the chapter into relationship with the accounts of modern evolutionary theory, and so go some way towards recovering the Bible’s reputation in our scientific age…. In so far as this argument begins with an attempt to go beyond the literal meaning and to take the week assigned to Creation as a parable of a much longer period, it is to be commended.23

In 1983 the German commentator Hansjö Brä states:

The creation ‘day’ which is described to contain ‘evening and evening [sic]‘ is not a unit of time which can be determined with a watch. It is a divine day in which a thousand years are equal to but yesterday [Ps. 90:4 in margin]. Day one in creation is a divine day. It cannot be an earthly day since the temporal measure, the sun, is still missing. It will, therefore, do no harm to the creation account to understand creation in rhythms of millions of years.24

D. Stuart Briscoe, an American progressive creationist, addresses the issue in his commentary on Genesis as well:

The natural scientist talks convincingly in terms of millions of years and evolutionary eras while the Bible believer looks at the six days and wonders what on earth to do…. It is not at all unreasonable to believe that ‘day’ (Hebrew, yôm), which can be translated quite literally as ‘period,’ refers not to literal days but to eras and ages in which God’s progressive work was being accomplished.25

Explanations of this kind can be duplicated and derive typically from scholars who are in the concordist camp. More precisely they belong to the branch of “broad concordists” who in recent times are associated with progressive creationism.26

2. Analysis and Evaluation of Psalm 90:4 and 2 Peter 3:8

Psalm 90:4
Let us begin with considerations concerning Psalm 90:4. This passage has been invoked time and again to indicate that the creation “days” are to be non-literal, standing for long periods/epochs/ages of time.

Psalm 90:4 reads: “For a thousand years in Thy sight are like yesterday when it passes by, or [lit.'and'] as a watch in the night” (New American Standard Bible).27 Of immediate interest is the comparison of the long time-period of 1,000 years with but “yesterday” and “a watch in the night.” This Scripture passage contains a comparative particle in the original Hebrew to make the comparison between 1,000 years and “yesterday” and “a watch in the night.” The comparative particle is rendered into English either as “like” or “as.”

From the point of view of Hebrew syntax this comparative particle serves not only the expression “yesterday” but also the expression “as a watch in the night.” It applies to both phrases. This demonstrates that the comparison is not between a “day” being like 1,000 years. A thousand years with God are “like” yesterday, that is, the past day, or “like” “a watch in the night,” which is even a briefer period of time than “yesterday.” The point is that God reckons time differently from the way humans reckon time.

Genesis 1 is not interested in depicting how God reckons time. The Genesis context of creation speaks of “days” in the sense of creation time during which God created this world and whereby He set the rhythm of the week. Genesis 1 does not explain or address how time is reckoned on God’s scale, but how the creation “days” set the norm for subsequent days in the weekly cycle of time.

Furthermore, Genesis 1 1acks any comparative particle such as “like” or “as” in connection with the usage of the term “day.” The lack in Genesis 1 of a Hebrew comparative expression with either the term “day,” or the expression “evening and morning,” indicates that no comparison is intended. Comparison is not the issue in Genesis 1. The issue is the amount of time God uses to create the world and whether this time period is identical to the seven-day week which is the rhythm of historical time.

From contextual as well as grammatical-syntactical and semantic points of view the application of Psalm 90:4 to Genesis 1 does not work. Appropriate linguistic and phraseological criteria of comparison are lacking. Those who link the two texts are insensitive to contextual, linguistic and phraseological criteria. The impression is left that those who compare the “days” of Genesis 1 with the “yesterday” and the “watch in the night” or the 1,000 years in God’s scale of time compare apples with oranges.

Another type of objection has been noted in making the creation “days” into long periods of time: if one were to read the “sixth day as the sixth epoch of creation, this opens the door to some kind of pre-Adamic homo [sic] sapiens.”28 In other words, the long-age substitution for a literal “day” does away with the view that Adam and Eve were the first human beings which God created on Earth.

A third difficulty relates to the fact that Psalm 90 is not a creation psalm. Contextually speaking Psalm 90 does not address the issue how God regards the “days” of creation but how humans are to regard time when compared to time in the realm of God.
Fourth, Psalm 90 does not even use the term “day” by itself. It is used in a linguistic relationship in verse 4 in which two words are syntactically joined together. The English language has one word for that linguistic relationship, “yesterday.” But “yesterday” in Psalm 90:4 is in parallelism with the expression “as a watch in the night,” i.e., a very short interval of time. This means that the 1,000 years are not compared simply to a day but to a short interval of time.

In short, Psalm 90:4 does not define the meaning of the designation “day” in Genesis 1. In view of the problems cited and other difficulties that exist,29 it is not surprising that many of those who currently take the “day/age theory” as a solution to the tension between science and religion refrain from referring to Psalm 90:4. This text when read on its own terms does not address the issue of the length of the creation “day.”

2 Peter 3:8
Broad concordists have also used 2 Peter 3:8, “… with the Lord one day is as a thousand years,” to support the day-age theory. It has been taken by some as a “biblical” mathematical equivalent “one day equals a thousand years” literally. Others take the 1,000 years to mean a long period, an age, or the like. In that case it is argued that “one day equals a long period of time” or “one day equals an age.”

It should be pointed out that those who invoke this text face several major problems: 1) 2 Peter 3:8 has no creation context; 2) 2 Peter 3:8 has a comparative particle which is lacking in Genesis 1; 3) 2 Peter 3:8 is used non-literally when the 1,000 years are taken to mean an “age” or the like; 4) 2 Peter 3:8 reveals that God is not limited to time or subject to it in fulfilling His promises.

The intent of this passage is well put by Lloyd R. Bailey, a broad concordist himself:

The text of 2 Peter (3:8) has been misused by those who would bring it to bear upon the word ‘day’ in Genesis 1…. Rather, the purpose of that text is to point out that ‘The Lord is not slow about his promise … but is forbearing … not wishing that any should perish …’ (3:9; cf v. 4). That is, God is not subject to time in the sense that humans are (”… as some count slowness,” v. 9). The intent, then, is to make a statement about God’s fidelity to promises, and not to define the meaning of the word ‘day’ as it is used in Genesis 1.30

It seems best to let 2 Peter 3:8 make its own point and not to use it for something which is topically, contextually, and linguistically unrelated.

3. “Days of Revelation”?

The theory that the creation “days” are actually “days of revelation” is held by a few scholars today.

This theory was brought to prominence by the Scottish geologist Hugh Miller in the nineteenth century.31 In this century P. J. Wiseman has revived it in his 1946 publication,Creation Revealed in Six Days, which was reprinted in 1977.32

According to this interpretation God did not create the world in six days, but He “revealed” and explained in six literal days to man what He had already done over many spans of time. The recurring phrase, “and God said,” is taken to support the theory that the “days” of creation are actually “days of revelation.” In this theory the world does not require a relatively recent origin nor creation in six literal 24-hour days.

It has been noted incisively that the “days of revelation theory,” also called the “vision theory,” rests to a large degree upon a “misunderstanding of the word ‘made’, in Exodus 20:11″ 33 for which Wiseman claims the meaning “showed.”34

The meaning of “showed” is not a valid meaning for the Hebrew term ‘asah. There is no Hebrew-English dictionary which supports this meaning for this Hebrew term. The Hebrew term ‘asah, which is used more than 2,600 times in the Old Testament, means “to make, manufacture, produce, do, etc.”35 but never once does it mean “to show” in either the Old Testament or in extra-biblical Hebrew.36 The meaning “to show” is invented for the sake of the theory. In view of this fact it is not surprising that the “days of revelation theory” has not found much support.37

In summary, current broad concordists seek to interpret Genesis 1 in some sort of “figurative, symbolic, or otherwise loose reading — such as the idea that the ‘days’ of Genesis 1 may be interpreted as long periods of time.”38 The purpose is to make an accommodation to current claims of the evolutionary theory for long time. Based on this time frame hypothesis, Scripture is reinterpreted to bring about some sort of harmony between the claims of the biblical creation account and naturalistic evolution. Those who seek to make adjustments in Scripture for the sake of concordism are known as broad concordists.

In contrast, strict concordists are scholars of equal erudition and skill. They are also interested in bringing about harmony between science and religion. However, they are unwilling to give the biblical text a “loose reading.” They agree that a meaning of a text is to be based on the internal criteria of language and its usage according to the commonly accepted standards of linguistics. They agree that the context of Scripture is primary and that the linguistic standards need to follow sound grammatical-syntactical conventions. Thus, strict concordists are fully aware of the tensions but resist forcing a meaning on the biblical text that is not supported by sound linguistic analysis.

IV. THE LITERARY GENRE OF GENESIS 1

1. Literary Genre/Form Argument

The recent Genesis commentary by evangelical scholar Victor P. Hamilton takes the position that the “days” of Genesis 1 must be taken as non-figurative and nonmetaphorical, that is, as literal, consisting of solar days of 24 hours.39 However, as a broad concordist he is already committed to long ages and remains interested in bringing about a harmony with modern naturalistic science. In order to do so he appeals to “a literary reading of Gen. 1 [which] still permits the retention of ‘day’ as a solar day of 24 hours.”40 How is this accomplished?

Hamilton speaks of a “literary reading” of the Genesis creation account. The “literary reading” allows him to understand the “days” of creation literally but “not as a chronological account of how many hours God invested in His creating project, but as an analogy of God’s creative activity.”41 In this view the 24-hour “days” in Genesis 1 are but an “analogy” based on a “literary [non-historical] reading” of the Genesis creation account.

This view of a “literary reading” is dependent on Charles E. Hummel.42 Hummel argues that even if the “days” in Genesis 1 are to be meant as solar days of 24 hours, which he believes they are, “the question still remains whether the [literary] format is figurative or literal, that is, analogy of God’s creative activity or a chronological account of how many hours he worked.”43 Hummel believes that the “who” and “why” but not the “how” of creation is important (following Bernard Ramm) and that, therefore, the “analogy… provides a model for human work.”44

The “analogy” theory consists of the understanding of the literal “day” as “a metaphor” which uses “the commonplace (or commonly understood, if you wish) meaning of a word” (viz. the word “day”) “in a figurative manner.”45 The analogy transfer suggested by the “analogy” theory removes the schema of six days of work and one day of rest from a chronological piece of information and makes it into a broad pattern of work-and-rest applicable to humanity.46

As appealing as this “analogy” theory seems to be, the issue is still the problem of the contextual and literary warrant within the context of Genesis 1 and the Bible as a whole for taking the time designation “day” as simply analogous for work/rest. Hummel is forced (followed by Hamilton) to redefine the literary genre of Genesis l from that of a straightforward creation account to a genre which is designated as a “semipoetic narrative”47 which has significance. This falls under the “historical-cultural” approach to creation.48

It is evident that these broad concordist scholars are partially influenced by form-criticism and its genre method of interpretation. Form-criticism, a sub-method of the historical-critical method, was begun by Hermann Gunkel, known as the father of form criticism, at the turn of the century.49 Gunkel raised the question, “Are the narratives of Genesis history or legend?”50 His premise is that “many things reported in Genesis … go directly against our better knowledge.”51 The idea of “our better knowledge” is an admission on Gunkel’s part that a naturalistic evolutionary world view provides the authoritative norm of what is history or legend. Thus, he suggested that the literary genre of Genesis is not history but “legend.” Gunkel was the first liberal scholar to assign to the creation account in Genesis a literary genre other than history in the sense of a factual account. He has been followed by other liberal scholars, by neo-orthodox theologians, and now also in part by neoevangelical scholars who are broad concordists.

Although we need not attempt to be exhaustive in citing the literary genre categories which have been proposed for categorizing Genesis, some major representative examples should be cited. Karl Barth, the father of neo-orthodox theology, takes Genesis 1-2 as “saga”52 and, of course, non-historical. S.H. Hooke, the leader of the myth-and-ritual school, says that the Genesis creation account is a “cultic liturgy.”53 Gordon Wenham, a neo-evangelical scholar, believes it to be a “hymn.”54 Walter Brueggemann, a liberal non-concordist, suggests that it is a “poem.”55 Claus Westermann, a form-critic, calls it a “narrative.”56 John H. Stek, a broad concordist, names it a “metaphorical narration.”57Gerhard von Rad, a tradition critic, designates it as “doctrine.”58 Others hold that it is a “myth,”59 “parable,”60 “story,” “theology,”61 “allegory,” etc.

There are several essential observations to be made in view of this plethora of current opinions on the nature of the literary genre of the Genesis creation account.

1) The obvious consensus is that there is no consensus on the literary genre of Genesis 1. This makes the literary genre approach for a non-literary reading of Genesis 1 suspect of special pleading.

Since there is no consensus, the careful interpreter will be rather cautious and avoid jumping on the bandwagon of literary genre identification with the aim to redefine the literal intent of Genesis 1. The intention of form-critical genre description from its beginning, the time of Gunkel to the present, has been to remove the text of Genesis 1 from being considered to be historical and factual in nature.62

2) The “literary genre” approach reveals it to be another way, at first used by non-concordists, to remove the creation account of Genesis from functioning as an authoritative, literal text which has implications for the relationship of science and the Bible. It is rightly suggested that “the way in which God revealed the history of creation must itself be justified by Scripture”63 and not by appeal to form-critical literary genre description from which historicity is removed.

3) Interpreters following the “literary genre” approach with the aim to remove the creation account from the realm of its literal intent feel free to interpret the “days” of creation in a literal and grammatical way.

The use of the “literary genre” approach is meant to restrict the meaning of Genesis 1 to a thought-form which does not demand a factual, historical reading of what took place. The “literary genre” redefinition of the creation account is intended to remove the creation account from informing modern readers on “how” and “in what manner” and in what time God created the world. It simply wishes to affirm minimalistically that God is Creator. And that affirmation is meant to be a theological, nonscientific statement which has no impact on how the world and universe came into being and developed subsequently.

The “literary genre” approach is based on a literary critical methodology,64 which is intended to assign to the creation account as a whole a function different from that of historicity or factuality. In this case it does not matter whether the creation “days” are taken as literal 24-hour days in its intent, because the account as a whole, including the creation “days,” has a meaning other than a historical or factual one.

2. Genesis 1: Literal or Figurative?

The question remains whether the creation account of Genesis 1 is literal or figurative as a whole.65 Often Genesis 1 is taken together as part of the larger unit of Genesis 1-11 to answer the question of its nature, purpose and function.

It is an acknowledged fact that these chapters at the beginning of the book of Genesis have singularities, that is, unrepealed, one-time events, that have no immediate analogy in present experience.

How does the modern historian handle such singularities? The standard position of modern historiography is based on the principle of analogy (cf. Ernst Troeltsch), that is, the principle that nothing in past experience can be reckoned to be historical except as it corresponds to present experience.66 This principle is based on the notion of the basic uniformity of human experience and historical events.67 The principle of analogy holds that the past is understood only by borrowing from the present and applying it to the past.

Based on the consistent application of this uniformitarian basic to the principle of analogy, there is cause to deny the historicity and facticity of most of Genesis 1-11, including the creation account of Genesis 1.

Can and should the uniformitarian principle of analogy reign as the supreme norm for understanding the past?68 “A problem arises when the uniformity [of past and present] is raised to a universal principle that makes some evidence inadmissible,” writes a strong supporter of the principle of analogy and modernistic historiography.69 This admission of the problem requires great caution in the application of the uniformitarian principle of analogy.

Human beings know of experiences in present reality that are singular and without parallel in the past. For example, twenty-five years ago the first human beings were walking on the moon. This had never happened before. Another example is the use of atomic bombs for the destruction of two Japanese cities in 1945. This type of destruction has never happened before and stands unique to the present. Many other singularities could be mentioned.

As there are singularities today that are either man-made or part of another order, that is to say, there are real events and situations that have no analogy in the past, so one can recite singularities in the past which have no analogy at present. For example, R. G. Collingwood, the famed British philosopher of history, noted that the ancient Romans engaged in population control by exposing newborn infants to die. This is a singularity which has no analogy at present in population control attempts.70

With these limitations of the principle of analogy in mind,71 it is not sound to reject the creation account as non-historical and non-factual because we know of no analogy at present. Genesis 1 contains singularities that may be perceived to be just as real, historical and factual as the singularities of another kind in the present or the past.

There are good reasons for maintaining that Genesis 1 is a factual account of the origin of the livable world. This record is accurate, authentic and historical.

3. Genesis 1 and Comparative Literature of the Past

From a purely comparative approach of the literary structures, the language patterns, the syntax, the linguistic phenomena, the terminology, the sequential presentation of events in the creation account, Genesis 1 is not different from the rest of the book of Genesis72 or the Pentateuch for that matter.

Compared to the hymns in the Bible, the creation account is not a hymn; compared to the parables in the Bible, the creation account is not a parable; compared to the poetry in the Bible, the creation account is not a poem; compared to cultic liturgy, the creation account is not a cultic liturgy. Compared to various kinds of literary forms, the creation account is not a metaphor, a story, a parable, poetry, or the like.

One recent study of the literary form of Genesis 1-11 done on the basis of current comparative Near Eastern literature has concluded that “we are dealing with the genera of historical narrative-prose, interspersed with some lists, sources, sayings, and poetical lines.”73 This is a fairly good description of the content of Genesis 1.

A detailed study of the literary form of Genesis 1 has concluded that we are dealing with the literary genre of “prose-genealogy.”74 Even Gunkel noted long ago that Genesis is “prose.” He noted also that it is “more artistic in its composition and has some sort of rhythmical construction.”75 The non-poetic nature of Genesis 1 shows that its intention is to take it in its plain sense as a straightforward and accurate record of creative events.

Looking at the information provided in Genesis 1 from a perspective of comparison with other ancient Near Eastern literature, it must be concluded that “Genesis 1 has no parallel anywhere in the ancient world outside the Bible.”76 Genesis 1 is the most cohesive and profound record produced in the ancient world of “how” and “when” and by “whom” and “in what manner” the world was made. There is no parallel to it from the ancient world in any type of literature. There are bits and pieces which have been compared from various cosmogonic myths and speculations, but the biblical creation account as a unit stands unique in the ancient world in its comprehensiveness and cohesiveness.77

4. The Literary Form of Genesis 1 Within Its Biblical Context

It would be helpful to analyze the literary form in distinction to the “literary genre” of form criticism discussed above.

John H. Stek suggests that the “literary type [of Genesis 1], as far as present knowledge goes, is without strict parallel; it is sui generis.”78 It has already been noted that the presentation and content of Genesis 1 as a whole is unparalleled in the ancient world.79 Does this mean, however, that it is sui generis in the sense that it should not be understood to be literal in its intention? Surely as creation itself is unique so the creation account is of necessity unique. But it is hardly sui generis in an exclusive literary sense which will remove it from communication on a factual, accurate and historical level.

Based on the relationship with the remainder of Genesis (and the Bible as a whole), the creation account (Genesis 1:1 – 2:3), can be properly designated in its literary form. The creation account of Genesis 1 is a historical prose-record, written in rhythmic style, recording factually and accurately “what” took place in the creation of “the heavens and the earth,” depicting the time “when” it took place, describing the processes of “how” it was done and identifying the divine Being “who” brought it forth. The result of creation week was a perfect, “very good” world with an environment suited to the utmost for created humanity to live in. This historical prose-record of creation reports correctly in specific sequences the creation events within chronological, sequential, and literal “days.” These “days” inaugurate the subsequent historical process of time ordered in weekly cycles in which man and nature function under God’s ultimate control. In this sense Genesis 1 is the inaugural history80 of initial beginnings which shapes from creation week onward the following flow of the history of the world and humanity.

V. LITERAL INTERPRETATION OF CREATION “DAYS”

We shall consider the usage of “day” (Hebrew yôm) along major lines of current scholarship. There are liberal and non-liberal scholars who have concluded that the word “day” (Hebrew yôm) in Genesis 1 must be singularly understood in a literal sense. We will review some of their reasons and provide additional ones.

1. Considerations from Commentaries

The influential Continental liberal Old Testament theologian and exegete Gerhard von Rad states, “The seven days are unquestionably to be understood as actual days and as a unique, unrepeatable lapse of time in the world.”81 Gordon Wenham, a British non-concordist Old Testament scholar, concludes, “There can be little doubt that here ‘day’ has its basic sense of a 24-hour period.”82 James Barr, renowned Semitist and Old Testament scholar, notes with vengeance against flgurative interpreters that the creation “days” were six literal days of a 1 44-hour period.83 Form critic Hermann Gunkel concluded long ago, “The ‘days’ are of course days and nothing else.”84 This refrain can be continued with many additional voices, sharing the same non-concordist position.

Victor P. Hamilton concludes, as do other broad concordist neoevangelical scholars, “And whoever wrote Gen. l believed he was talking about literal days.”85 John H. Stek, another broad concordist, makes a number of points in his support for literal “days”:

Surely there is no sign or hint within the narrative [of Genesis 1] itself that the author thought his ‘days’ to be irregular designations — first a series of undefined periods, then a series of solar days — or that the ‘days’ he bounded with ‘evening and morning’ could possibly be understood as long aeons of time. His language is plain and simple, and he speaks in plain and simple terms of one of the most common elements in humanity’s experience of the world…. In his storying of God’s creative acts, the author was ‘moved’ to sequence them after the manner of human acts and ‘time’ them after the pattern of created time in humanity’s arena of experience.86

Numerous scholars and commentators, regardless of whether they are concordist or non-concordist, have concluded that the creation “days” cannot be anything but literal 24-hour days. They are fully aware of the figurative, non-literal interpretations of the word “day” in Genesis 1 for the sake of harmonization with the long ages demanded by the evolutionary model of origins. Yet, they insist on the ground of careful investigations of the usage of “day” in Genesis 1 and elsewhere that the true meaning and intention of a creation “day” is a literal day of 24 hours.

2. Considerations from Lexicography

The most widely recognized Hebrew lexicons and dictionaries of the Hebrew language published in the twentieth century affirm that the designation “day” in Genesis 1 is meant to communicate a 24-hour day, respectively, a solar day.

A prestigious recently published lexicon refers to Genesis 1:5 as the first scriptural entry for the definition of “day of 24 hours” for the Hebrew term yôm (”day”).87 Holladay’s Hebrew-English lexicon follows suit with “day of 24 hours.”88 The Brown-Driver-Briggs lexicon, the classical Hebrew-English lexicon, also defines the creation “day” of Genesis 1 as a regular “day as defined by evening and morning.”89

Lexicographers of the Hebrew languages are among the most qualified of Hebrew scholars. They are expected to give great care in their definitions and also usually indicate alternative meanings, if there is warrant to do so in given instances. None of the lexicographers have departed from the meaning of the word “day” as a literal day of 24 hours for Genesis 1.

3. Considerations from Dictionaries

Magne Saeboe writes in the acclaimed Theological Dictionary of the Old Testament that the “day” (yôm) in Genesis 1 has a literal meaning in the sense of “a full day.”90 He does not entertain another meaning or alternative.

Ernst Jenni, an acclaimed Hebrew scholar of the twentieth century, states in the most-widely used theological dictionary of the Hebrew language that the meaning of “day” in the Genesis creation account is to be understood in its literal meaning as a “day of 24 hours in the sense of an astronomical or calendrical unit of time.”91

4. Considerations Based on Semantics

The field of semantics in linguistic study refers to what is called signification.92 It deals with the issue of “the accurate evaluation of the meaning of expressions [words, phrases, clauses, sentences, etc.] which have actually been used.”93

Semantics calls for attention to the crucial question of the exact meaning of the Hebrew word yôm. Could the designation “day” in Genesis 1 possibly have a figurative meaning in this chapter? Is it to be understood on the basis of the norms of semantics as a literal “day”? This matter of semantics is particularly important in view of the fact that the Hebrew term yôm in the singular and plural has a large variety of meanings, including extended meanings such as “time,” “life time,” and so on. Is it possible to import an extended meaning from the Old Testament into Genesis 1? Could this not solve the problem of the conflict of a short creation week and the long ages called for by naturalistic evolution?

The Hebrew term yôm, in its variety of forms, can mean aside from a literal “day” also a time or period of time (Judges 14:4) and in a more general sense “a month [of] time” (Genesis 29:14), “two years [of] time” (2 Samuel 13:23;14:28; Jeremiah 28:3,11), “three weeks [of] time” (Daniel 11:2, 3). In the plural form it can mean “year” (1 Samuel 27:7), a “life time” (Genesis 47:8), and so forth. Any good lexicon will provide a comprehensive listing of the various possibilities.94

It is important to keep in mind that “the semantic content of the words can be seen more clearly in their various combinations with other words and their extended semantic field.”95

What are the semantic-syntactical guidelines for extended, non-literal meanings of the Hebrew term yôm? The extended, non-literal meanings of the term yôm are always found in connection with prepositions,96 prepositional phrases with a verb, compound constructions, formulas, technical expressions, genitive combinations, construct phrases, and the like.97 In other words, extended, non-literal meanings of this Hebrew term have special linguistic and contextual connections which indicate clearly that a non-literal meaning is intended. If such special linguistic connections are absent, the term yôm does not have an extended, non-literal meaning; it has its normal meaning of a literal day of 24-hours.

In view of the wealth of usages of this Hebrew term, it is imperative to study the usage of the term yôm in Genesis 1 so that it can be compared with other usages. Does this chapter contain the needed indicators by which yôm can clearly be recognized to have a literal or non-literal meaning? How is this term used in Genesis 1? Is it used together with combinations of other words, prepositions, genitive relations, construct state, and the like, as mentioned in the previous paragraph, which would indicate a non-literal meaning? It is exactly these kinds of semantic-syntactical combinations which inform us about the intention of the meaning of this term.

Let us present the facts of the usage of the term yôm, “day,” in Genesis 1 as any scholar who knows Hebrew can describe them:

  1. The term yôm is always used in the singular.
  2. The term yôm is always joined to a numeral. In Genesis 1:5 it is a cardinal and elsewhere in Genesis 1:1 – 2:3 it is always an ordinal. We will pay attention to this below.
  3. The term yôm is never combined with a preposition, genitive combination, construct state, compound construction, or the like. It always appears as a plain noun.
  4. The term yôm is consistently defined by a temporal phrase in the preceding sentence, “and there was evening and there was morning.” This clause serves in a defining function for the word “day.”
  5. The complementary creation account of Genesis 2:4-25 contains a non-literal, figurative meaning of the singular of the term yôm, “day.” When the non-literal meaning is intended the semantic-syntactical conventions known from the remainder of the Old Testament for such a meaning are employed. This is the case in the non-literal usage in Genesis 2:4.

Let us note these criteria as they are employed in Genesis 2:4. The noun yôm is joined to the preposition be to read beyôm. Secondly, it is used in a construct relation with the infinitive form of ‘asah, “to make.” It reads literally, “in the day of making.” This combination of the singular with a preposition in construct with an infinitive98 makes this combination a “temporal conjunction,”99 which serves as a “general introduction of time.”100

Genesis 2:4b reads literally, “in [the] day of the Lord God making the earth and heaven. Proper English calls for the literal “in [the] day of,” which is syntactically a temporal conjunction that serves as a general introduction of time, to be rendered with “when.” This sentence then reads, “When the Lord God made ….” This clear-cut case of an extended, non-literal use of yôm in the creation account of Genesis 2:4-25 shows that the contrary usage of yôm in Genesis 1, without any expected qualifier that marks it as a non-literal use, has a literal meaning. The term yôm in Genesis 1 has no prepositions; it is not used in a construct relation and it has no syntactical indicator expected of an extended, non-literal meaning. Thus, in Genesis 1 yôm can mean only a literal “day” of 24 hours.

In short, the semantic-syntactical usages of yôm, “day,” in Genesis 1 as compared with semantic-syntactical usages and linguistic connections of this term in other Old Testament passages where it has an extended meaning, does not allow it to mean a long period of time, an age, or the like. The Hebrew language, its grammar, syntax, linguistic structures as well as its semantic usage allows for only the literal meaning of “day” for the creation “days” of Genesis 1.

5. Considerations Based on Singular Usage

The Hebrew term yôm appears in the Hebrew Old Testament 2,304 times101 of which 1,452 usages are in the singular.102
In the Five Books of Moses (Pentateuch) this term is used 668 times and in the book of Genesis it is employed 152 times.103 In Genesis the singular usage of “day” appears 83 times, the remainder usages are in the plural.

In the enumeration of the six “days” of creation the term “day” is used consistently in the singular. There is one plural use in the phrase “for days and years” in vs.14 which is, of course, not a creation “day.” This plural usage in vs.14 hardly enters the discussion of making creation “days” long periods of time since calendrical usage of “days and years” keeps it literal itself. There is no doubt but that the literal meaning of 24-hour days are meant in vs.14 just as the “years” are likewise understood as literal years.

The additional usages of “day” in the singular in Genesis 1 are found in vss.5 and 16. “And God called the light ‘day’ (yôm)” (vs.5) and God made the “greater light to govern the day” (vs.16). The term in vs.5 is employed in the sense of the literal daylight period of the light part of the 24-hour period of time in contrast to the night part, “the night” (vs. 16), of the same period of time.104 Both “day” and “night” make a “full day.”105

We have to recognize the fact that the term yôm in every one of the six days has the same connection: a) It is used as a singular; b) it has a numeral; and c) it is preceded by the phrase, “there was evening and there was morning.” This triple interlocking connection of singular usage, joined by a numeral, and the temporal definition of “evening and morning,” keeps the creation “day” the same throughout the creation account. It also reveals that “time is conceived as linear and events occur within it successively.”106 To depart from the numerical, consecutive linkage and the “evening-morning” boundaries in such direct language would mean to take extreme liberty with the plain and direct meaning of the Hebrew language.107

6. Considerations Based on Numeral Usage

The six creation “days” are in each instance joined with a numeral in the sequence of one to six (Genesis 1:5,8,13,19,23,31). The day following the “sixth day,” the “day” on which God rested, is designated “the seventh day” (Genesis 2:2 [2 times],3).

What seems of significance is the sequential emphasis of the numerals 1-7 without any break or temporal interruption. This seven-day schema, the schema of the week of six workdays followed by “the seventh day” as rest day, interlinks the creation “days” as normal days in a consecutive and non-interrupted sequence.

When the word yôm, “day,” is employed together with a numeral, which happens 150 times in the Old Testament, it refers in the Old Testament invariably to a literal day of 24 hours.

This rule is pervasive in the Old Testament. The only exception in numbers of 1-1,000 is found in an eschatological text in Zechariah 14:7. The Hebrew expression yôm ‘echad employed in Zechariah 14:7 is rendered into English in a variety of ways: “for it will be a unique day” (New American Standard Bible, New International Version); “and there shall be continuous day” (New Revised Standard Version); “it will be continuous day” (Revised English Bible); or “and the day shall be one.”108 The “continuous day,” or “one day,” of the eschatological future will be one in which the normal rhythm of evening and morning, day and night, as it is known will be changed so that in that eschatological day there shall be “light even at the evening” (vs.7). It is generally acknowledged that this is a difficult text in the Hebrew language and can hardly be used to change the plain usage in Genesis 1.109

7. Considerations Based on Article Usage

The term “day” is used in Hebrew without the article in each instance of each creation day, except in the cases of “the sixth day” (Genesis 1:31, Hebrew yôm hashshishî) and “the seventh day” (Genesis 2:2).110

It is noted from time to time that the first “day” of Genesis 1:5 in Hebrew reads literally “one day,”111 because we have the cardinal number “one” used with the term “day.”

The lack of the definite article has been interpreted to mean that all creation “days” (except “the sixth day,” which has the article) will allow “for the possibility of random or literary order as well as a rigidly chronological order.”112 This is a rather shaky interpretation. It cannot be supported from semantic-syntactical points of view.

We need to understand the syntax of the Hebrew text and interpret the text accordingly without violence to the internal structure of the Hebrew language. The recent research grammar by Bruce K. Waltke and M. O’Connor points out that the indefinite noun yôm with the indefinite cardinal numeral for “one” (Hebrew ‘echad) in Genesis 1:5 has “an emphatic, counting force” and a “definite sense” in addition to having the force of an ordinal number which is to be rendered as “the first day.”113

Based on this syntactical observation of the Hebrew language, “the first day” and “the sixth day” of the creation week are meant to be definite in the sense that they have the article by syntactical rule or by writing (not to speak of “the seventh day” which will be considered below). The first and last creation “days” are definite by syntax or writing, the first by syntactical function and the last by the usage of the article. One observation emerges — this definite usage of the first and last day of creation forms a literary device, an inclusio, which frames the six creation “days” with definite or articular days. One of the intentions of this usage seems to be that the “days” of Genesis 1 do not permit the conclusion that random order or chronological order is an open-ended issue.114

The opposite is actually the case. Since the first and sixth days are definite, providing a clear boundary, the days are meant to be chronological and sequential, forming an uninterrupted six-day period of literal 24-hour days of creation. Thus, the definite use of the first and sixth days respectively mark and frame the six-day sequence into a coherent sequential and chronological unit of time which will be repeated in each successive week.

“The seventh day” is also written with the Hebrew article. Since “the first day” (vs.5) is definite as well as “the sixth day” (vs.31), a larger unit is formed. It is the unit of six workdays followed by “the seventh day” (Genesis 2:2,3), the day of rest. In this way the sequence of six workdays find their goal and climax chronologically and sequentially in “the seventh day,” making together the weekly cycle with the day of rest being the “seventh day” of the week.

The larger unit of literal time accordingly consists of the divinely planned unit of the “six-plus-one schema” which consists of the “six” workdays followed in an uninterrupted manner and in sequence by “the seventh day” of rest. This uninterrupted sequence is divinely planned and ordained as the rhythm of the time for each successive week.

8. Considerations Based on the “Evening-Morning” Boundary

The Genesis creation account not only links each day to a sequential numeral but it also sets the time boundaries by “evening and morning” (vss.5,8,13,19,23,31). The rhythmic boundary phrase, “and there was evening and there was morning,” provides a definition of the creation “day.” The creation “day” is defined as consisting of “evening” and “morning.” It is a literal “day.”

The term for “evening” (Hebrew ‘ereb)115 covers the dark part of the day in a pars pro toto (meaning that a part, in this case the “evening,” stands for the whole dark part of the day) usage (cf. “day-night” in Genesis 1:14). The corresponding term “morning” (Hebrew bqer) stands pars pro toto (meaning that a part, in this case the “morning,” stands for the light part of the day) “for the entire period of daylight.”116 It is to be noted that the “evening-morning” expression must be understood to have the same signification in every one of its six usages.117

“Evening and morning” is a temporal expression which defines each “day” of creation as a literal day. It cannot be made to mean anything else.

9. Considerations Based on Pentateuchal Sabbath Passages

Another kind of internal evidence provided in the Old Testament for the meaning of days derives from two Sabbath passages in the Pentateuch which refer back to the creation “days.” They inform the reader how the creation “days” were understood by God.

The first passage is part of the Fourth Commandment spoken by God on Mt. Sinai and recorded recorded in Exodus 20:9-11: “Six days you shall do all your labor … but the seventh day is the sabbath of the Lord your God…. For in six days the Lord made the heavens and the earth … and rested on the seventh day; therefore the Lord blessed the sabbath day and made it holy.”

“These words” are spoken by Yahweh Himself (vs. 1). The linkages to creation are in wording (”seventh day,” “heaven and earth,” “rested,” “blessed,” “made it holy”) and in the “six-plus-one” schema (see also Deuteronomy 5:13-14) to mention but these.118 Evidently the words used in the Ten Commandments take the creation “day” as “a regular day”119 of 24 hours and demonstrate that the weekly cycle is a temporal creation ordinance.

These words of the Lord provide an internal Pentateuch and Old Testament guideline on how God, the Giver of the “Ten Words” understands the creation “day.” The divine speech which promulgates the Sabbath commandment takes the “six days” of creation to be sequential, chronological and literal.120

The argument that the relationship of the Fourth Commandment is but an “analogy” or “archetype” in the sense that man’s rest on the seventh day ought to be like God’s rest in creation121 is based on reductionism and an impermissible change of imagery. Terence Fretheim noted incisively that the Commandment does not use analogy or archetypal thinking but that its emphasis is “stated in terms of the imitation of God or a divine precedent that is to be followed: god worked for six days and rested on the seventh, and therefore you should do the same.”122

The second Pentateuchal Sabbath passage is Exodus 31:15-17, which is again spoken by God Himself. It has several terminological linkages with Genesis 1 and is conceptually and thematically related to it. This passage has to be understood to mean that the creation “day” was a literal day and that the days were sequential and chronological. The weekly sabbath for God’s people is based on imitation and example, for “in six days the Lord made heaven and earth, but on the seventh day he ceased from labor, and was refreshed” (vs. 17, New American Standard Bible).

God was refreshed because He had delight in His completed work of creation. Humankind will also be refreshed and have delight when the Sabbath as “seventh day” (vs. 15) is kept.

The “sign” nature of the Sabbath in vs. 15 reveals that the Sabbath keeper follows the divine Exemplar. He Himself kept “the seventh day” which humans who belong to Him will imitate. They will do so in the same rhythm of the literal weekly cycle of six literal workdays followed chronologically and sequentially by “the seventh day” as a day of rest and refreshment as their Creator had done during creation week.

10. Considerations Based on Sequence of Events

The creation of vegetation with seed-bearing plants and fruit trees took place on the third day (Genesis 1:11-12). Much of this vegetation seems to need insects for pollination. Insects were created on the fifth day (vs.20). If the survival of those types of plants which needed insects for pollination depended on them to generate seeds and to perpetuate themselves, then there would be a serious problem should the creation “day” consist of long ages or aeons. The type of plant life dependent on this type of pollination process without the presence of insects could not have survived for these long periods of time, if “day” were to mean “age” or “aeon.” In addition, “consistency of interpretation in the ‘day-age theory’ would demand a long period of light and darkness during each of the ages. This would quickly be fatal both to plant and animal life.”123

It seems that the creation “day” is expected to be understood as a literal day and not as a long period of time whether ages, periods, or aeons.

Although these arguments may not be decisive, they nevertheless point in the same direction as the decisive linguistic and semantic points which are found in the Hebrew text itself.

VI. CONCLUSIONS

This paper investigated the meaning of creation “days.” It has considered key arguments in favor of a figurative, non-literal meaning of the creation “days.” It found them to be wanting on the basis of genre investigation, literary considerations, grammatical study, syntactical usages, and semantic connections. The cumulative evidence, based on comparative, literary, linguistic and other considerations, converges on every level, leading to the singular conclusion that the designation yôm, “day,” in Genesis 1 means consistently a literal 24-hour day.

The author of Genesis 1 could not have produced more comprehensive and all-inclusive ways to express the idea of a literal “day” than the ones that were chosen. There is a complete lack of indicators from prepositions, qualifying expressions, construct phrases, semantic-syntactical connections, and so on, on the basis of which the designation “day” in the creation week could be taken to be anything different than a regular 24-hour day. The combinations of the factors of articular usage, singular gender, semantic-syntactical constructions, time boundaries, and so on, corroborated by the divine promulgations in such Pentateuchal passages as Exodus 20:8-11 and Exodus 31:12-17, suggest uniquely and consistently that the creation “day” is meant to be literal, sequential, and chronological in nature.

ENDNOTES

  1. The designation “creation-science” has been defined by Louisiana law (Senate Bill No. 86, 1981) as follows: “‘Creation-science’ means the scientific evidences for creation and inferences from those scientific evidences.” A similar wording was used shortly before in the Arkansas Bill (Act 590) of March 19, 1981. For details, see: Norman L. Geisler, The Creator in the Courtroom (Milford, MI: Mott Media, 1982), 5, 224. Phillip E. Johnson (Darwin on Trial, 2d ed. [Downers Grove, IL: InterVarsity Press, 1993], 4 n. 1) states that “‘creation science’ refers to young-earth, six-day special creation.”
  2. This designation is preferred and argued for by: Norman L. Geisler and J. Kerby Anderson, Origin Science: A Proposal for the Creation-Evolution Controversy (Grand Rapids, MI: Baker Book House, 1987).
  3. The significant volume of essays edited by J. P. Moreland (The Creation Hypothesis: Scientific Evidence for an Intelligent Designer [Downers Grove, IL: InterVarsity Press, 1994]) uses the designation “theistic science” as opposed to “naturalistic science,” the common notion of science which rules out the God-hypothesis from the start. “Theistic science” is a “research program … that, among other things, is based on two propositions: 1. God, conceived of as a personad, transcendent agent of great power and intelligence, has through direct, primary causation and indirect secondary causation created and designed the world for a purpose and has directly intervened in the course of its development at various times…. 2. The commitment expressed in proposition 1 can appropriately enter into the very fabric of the practice of science and the utilization of scientific methodology” (pp. 41-42). This definition is elaborated in the remainder of the seminal essay by J. P Moreland in the above volume (”Theistic Science & Methodological Naturalism,” 41-66).

The decisive section from Origen’s On First Principles: Book Four (excerpt quoted in Karifried Froehlich, trans./ed., Biblical Interpretation in the Early Church [Philadelphia: Fortress Press, 1984], 63) noted that the days of creation cannot be understood to be literal just as it “is foolish enough to believe that, like a human farmer, God planted a garden to the east of Eden and created in it a visible, physical tree of life….” See also Terence E. Fretheim, “Were the Days of Creation Twenty-Four Hours Long?” in The Genesis Debate: Persistent Ouestions About Creation and the Flood, ed. Ronald R.

  8. The new Catechism of the Catholic Church, published in English in 1994, states: “According to an ancient tradition, one can distinguish between two senses of Scripture: the literal and the spiritual, the latter being subdivided into the allegorical, moral [tropological], and anagogical senses. The profound concordance of the four senses guarantees all its richness to the living reading of Scripture in the Church.” Later on the same page it is affirmed: “It is the task of exegetes to work, according to these rules, toward a better understanding and explanation of the meaning of Sacred Scripture …” (Catechism of the Catholic Church [Vatican City: Libreria Editrice Vaticana, 1994], 33).

  11. The development of the historical-critical method from the late seventeenth century onward until its full matunty at the end of the nineteenth century did not decisively change the interpretation of the creation “days.” The reason for this is that the biblical text was now seen as an artifact of the past which has no direct relationship to the belief systems of the present.
  12. The Scottish theologian Thomas Chalmers (1780-1847) is credited with being the first proponent of the view that the six creation “days” are actually “days of reconstruction,” giving rise to the “ruin-reconstruction hypothesis” (see W. Hanna, ed., Select Works of Thomas Chalmers [Edinburgh: T. Constable and Co., 1855], 5: 146-150). This hypothesis has found strong defenders such as George H. Pember (Earth’s Earliest Ages, 2d ed. [London: Hodder and Stoughton, 1907]) and more recently A. C. Custance, Without Form and Void (Brookville, Ont: By the Author, 1970). The most detailed and scholarly critique of the “ruin-reconstruction hypothesis” has been produced by Weston W. Fields, Unformed and Unfilled: The Gap Theory (Phillipsburg, NJ: Presbyterian and Reformed Publishing Co., 1978). See also, Henn Blocher, In the Beginning: The Opening Chapters of Genesis (Downers Grove, IL: InterVarsity Press, 1984), 41-43.
  13. While not the first to claim that the days of creation are actually six days of revelation, and not days of creation, the Scottish geologist Hugh Miller (1802-1856) was the foremost nineteenth-century author to proclaim this idea (Francis Haber, The Age of the World: Moses to Darwin [Baltimore, MD: The Johns Hopkins University Press, 1959], 236-237). In this century this view was propounded by R J. Wiseman, the father of the famous Assyriologist Donald Wiseman. More on this later.
  14. The “day-age” theory originated in the eighteenth century and came to prominence in the nineteenth century through the writings of geologists James D. Dana and J. W. Dawson. See Bemard Ramm,The Christian View of Science and Scripture, 2d ed. (Grand Rapids, MI: Wm. B. Eerdmans Publishing Co., 1971), 211; and Haber, 122-123, 199-200, 255.

  20. In the final analysis the ultimate conclusion about the final norm for scientific views and religious faith is probably made on the basis of the conviction, or presupposition, of the interpreter’s stance on the authority levels of science and faith. We must also contend that science is constantly in flux and makes no absolute claims.

Garrett seeks to bolster the idea of “days” as “seven days of divine revelation to Moses” with form-critical arguments, an attempt quite problematical in itself.

  62. The genre/form approach so widely used today, especially by critical scholars but also employed for other reasons by some evangelicals to Genesis 1, is formally identical or closely associated with the demythologization program of Rudolph Bultmann. He demythologizes the New Testament at any place where it does not conform to the worldview of modern man. Thus, the resurrection narrative is demythologized in such a way that the resurrection never took place in a literal sense. Evangelicals have to be aware that they cannot demythologize Genesis 1 without carrying this over to the New Testament.

  65. We do not address the question of a structural interpretation of Genesis 1 by the method of structuralism which seeks to expose the alleged deep structures of a text. The subsequent method of deconstructionism in linguistics “is an attempt to undermine the reader’s expectations that a text will communicate some independently existing truth, by showing that author and reader alike are caught in the system of constraints imposed by the linguistic and literary system to which they belong, and are capable of communicating or receiving only such meanings as the system makes possible” (John Barton, “Structuralism,” Anchor Bible Dictionary, ed. David N. Freedman [NY: Doubleday, 1992], 6:216; cf. Jonathan D. Culler, The Pursuit of Signs: Semiotics, Literature, Deconstruction [Ithaca: Cornell University Press, 1981]). Just as deconstructionism denies to any text a fixed and stable meaning so in “reader-response criticism” the idea of a fixed meaning of a text is given up as well (see J. Severino Croatto, Biblical Hermeneutics: Toward a Theory of Reading as the Production of Meaning [Maryknoll, NY: Orbis Books, 1987]; Edgar V.

This is already true on the level of the descriptive task with which OT theology begins. For example, the scholar who accepts Ernst Troeltsch’s ‘analogy principle’ (i.e. to be credible, a happening recorded in a historical source must have parallels in modern experience) will dismiss all reconstructions of the Exodus from Egypt or the resurrection of Jesus, which defy explanation within the nexus of cause and effect as understood by modern science, whereas others may not be so bound.”

  104. Stek, 237, is correct in noting that each “day” of creation has to be the same since the “evening and moming” time expression and the numeral is in each instance identical. In other words, each creation “day” is of equal length. From this he shows that it is not defensible to argue that the first three “days” were long periods of time while the remaining “days” were 24-hour days. The latter position was argued by Edward J. Young, Studies in Genesis One (Philadelphia: Presbyterian and Reformed Publishing House, 1964), 104, and has found a recent supporter in R. Clyde McCone, “Were the Days of Creation Twenty-four Hours Long?” The Genesis Debate, 24. Young and followers are inclined to separate the lengths of creation days because they claim that the sun and moon had not been created yet until the fourth day. The question really is whether this is the case. It seems likely that on the fourth day God appointed the sun and moon to rule the day and night respectively. This appointment to the ruling function does not negate that the sun and moon were in existence before. It is possible that they were not visible to the human eye before the fourth day. Some have for this reason suggested that there may have been a vapor or cloud cover before the fourth day.

  109. The other exception is with numbers above 1,000 in the apocalyptic text of Daniel 12:11-12 with the reference to 1,290 “days” and the 1,335 “days.” There are some differences from Genesis 1. In both instances in Daniel 12 the plural form of “days” is employed in contrast to Genesis 1. In Genesis 1 the “day” refers to what has happened in the past; in Daniel 12 “days” refer to a prophetic time in the future. The context of all other prophetic time predictions in the book of Daniel makes it clear that in prophetic perspective each time element whether “times” (4: 16, 23,25,32), “time, times and half a time” (7:25), “evening[s and] morning[s]” (8:14), “weeks” (9:24), and respectively “days” (12:11-12) stands for another reality in real historical time. In other words in Daniel the year/day principle is at work each time a time prophecy is provided. The Danielic apocalyptic context is different from the creation context of Genesis 1. Time at the beginning, in creation, is not identical with predictive time which finds its fulfillment in the historical future. There is nothing predictive in Genesis 1. The latter is a prose-record of the past and not apocalyptic prophecy of the future. These content and contextual perspectives do not warrant a departure from the plain meaning in the Genesis creation account.
  110. In Genesis 1:31 the Hebrew has an article both before yôm and the numeral. In Genesis 2:3 the article is only before the numeral following the noun yôm. According to Hebrew syntax the article in the latter case makes the word which the numeral qualifies articular.

Potassium-Argon and Argon-Argon Dating (Part 3 of 15)

By Sean Pitman M.D.
Source: Detecting Design

Potassium-Argon and Argon-Argon Dating is 3 of 15 parts to Radiometric Dating Methods.

Since Potassium-Argon and Argon-Argon dating techniques are the most common and are considered, even by geologists, to be among the most accurate of all the radioisotope dating methods, lets consider these in particular detail.

Argon is a noble gas. The main isotopes of argon in terrestrial systems are 40Ar (99.6%), 36Ar (0.337%), and 38Ar (0.063%). Naturally occurring 40K decays to stable 40Ar (11.2%) by electron capture and by positron emission, and decays to stable 40Ca (88.8%) by negatron emission; 40K has a half-life of 1.25 billion years.

Most of the argon isotope literature deals with measurement of 40Ar for use in 40K/40Ar dating of rocks. The conventional 40K/40Ar dating method depends on the assumption that the rocks contained no argon at the time of formation and that all the subsequent radiogenic argon (i.e., 40Ar) was quantitatively retained. Minerals are dated by measurement of the concentration of potassium, and the amount of radiogenic 40Ar that has accumulated. The minerals that are best suited for dating include biotite, muscovite, and plutonic/high grade metamorphic hornblende, and volcanic feldspar; whole rock samples from volcanic flows and shallow intrusives can also be dated if they are unaltered (Faure, 1986).

Under some circumstances the requirements for successful 40K/40Ar dating may be violated. For example, if 40Ar is lost by diffusion while the rock cooled, the age-dates represent the time elapsed since the rock cooled sufficiently for diffusive losses to be insignificant.  Or, if excess 40Ar is present in the rock, the calculated age-dates are too old.  The 40Ar/39Ar method is thought to be able to overcome this problem inherent with the 40K/40Ar method.

The 40Ar/39Ar dating method is based on the formation of 39Ar as a result of the intentional irradiation of K-bearing samples within a nuclear reactor. The bombardment produces various isotopes of Ar, K, Ca, and Cl, but the dominant source of 39Ar is from 39K.  Radioactive 39Ar decays back to 39K by beta emission with a half-life of 269 years, but the decay is slow compared to the analysis time and can be ignored (Faure, 1986).  The principal “advantage” of 40Ar/39Ar dating is that argon can be released partially by stepwise heating of irradiated samples, producing a spectrum of dates related to the “thermal history of the rock” (understanding that Argon is a gas while Potassium is not).

Because of this, it is much easier to determine a 40K/40Ar ratio and do it in a stepwise fashion with varying amounts of time and heat.  This “stepwise” testing is thought to eliminate the errors caused by “extraneous” argon that might have “contaminated” the rock over time either by a loss or a gain of “outside” argon (ie: atmospheric argon).  The problem with this theory is that who is to know which step, or average of steps in the process represents the “correct” 40K/40Ar ratio?  How is this calibrated? Also, even if the argon-argon dating method does eliminate the “contamination” problem, it does not solve the problem of original argon.  Did the clock get reset to zero when the volcano erupted?  Or, was there some argon trapped in the rocks originally?  Also, the 40Ar/39Ar dating method is not an independent dating method.  It must be first calibrated against a sample of “known age”.  This age of this sample is usually determined by, you guessed it, the 40K/40Ar method (see discussion of Ar/Ar calibration below).

Recent experiments on volcanoes of known ages have been done using the 40Ar/39Ar dating method, which seem to confirm its accuracy.  Recent testing of volcanic material from Mt. Vesuvius was dated accurately with the 40Ar/39Ar method to within seven years of the actual event.3 40Ar/39Ar Dating into the Historical Realm: Calibration Against Pliny the Younger was written by P. R. Renne et. al. and published in Science 277: 1279-1280 (1997). Renne tested Ar-Ar dating by checking it against the 79 A.D. eruption of Vesuvius that destroyed Pompeii. Renne and his team noted that “Analysis of single crystals, for example by laser fusion, can obviate xenocrystic contamination, but single crystals are seldom large enough to yield measurable quantities of 40Ar* through radiogenic ingrowth in the Holocene [i.e. last 12,000 years].”  Would Ar-Ar dating methods work such recent material?  It apparently did. The testing returned an age of 1925±94 years. The true age was 1918 years.  The test was off only 7 years. The conclusions of Renne and his team read as follows:

Thus despite the presence of excess 40Ar, a sample less than 2000 years old can be dated with better than 5% precision, validating 40Ar/39Ar dating as a reliable geochronometer into the late Holocene. These results also demonstrate that excess 40Ar can be identified in volcanic sanidine, and while perhaps negligible in pre-Holocene rocks, it has important consequences for sample at the limit of the method’s applicability. Further improvement in precision of 40Ar/39Ar analysis of historically dated samples may lead to welcome refinements in the ages of neutron fluence monitors, currently a limitation on the accuracy of the 40Ar/39Ar method. Our results also substantiate validity of the 40Ar/39Ar method in establishing the eruptive histories of populated active volcanic regions, where such information is vital to volcanic hazard assessment.

Of note however is that this test was not double blinded, and the number of such tests is not statistically significant as far as scientific analysis is concerned.  Although interesting, it is basically a case study report, and as such it has very little scientific weight as far as statistical predictability.

Assumptions (Part 2 of 15)

By Sean Pitman M.D.

Assumptions is 2 of 15 parts to Radiometric Dating Methods.

Dating rocks by radioactive timekeepers is simple in theory, but almost all of the different methods (except for the isochron methods – see below) rely on these few basic assumptions: 21

  • Beginning Conditions Known
  • Beginning Ratio of Daughter to Parent Isotope Known (zero date problem)
  • Constant Decay Rate
  • No Leaching or Addition of Parent or Daughter Isotopes
  • All Assumptions Valid for Billions of Years
  • There is also a difficulty in measuring precisely very small amounts of the various isotopes

There is, of course, one radiometric dating method that appears to overcome the vital “zero date problem”.  The isochron dating method theoretically overcomes the need to know the initial ratio of parent and daughter isotopes.  It will be covered in more detail below.  For now, we will look at those methods that do fall under the above assumptions.

half livesInterweaving the relative time scale with the atomic time scale poses certain problems because only certain types of rocks, chiefly the igneous variety, can be dated directly by radiometric methods; but these rocks do not ordinarily contain fossils.  Igneous rocks are those such as granite and basalt, which crystallize from molten material called “magma”.   There is even some valid question as to if granite could be formed from magma at all since this has never, to my knowledge, been observed or duplicated in the lab.  Radio-halos from rapidly decaying radioactive isotopes in granite seem to indicate that the granites were formed almost instantly.

Most sedimentary rocks such as sandstone, limestone, and shale (which do contain fossils) are related to the radiometric time scale by bracketing them within time zones that are determined by dating appropriately selected igneous rocks in lava flows, or weathered from lava flows.Potassium – Argon and Argon – Argon dating are based on the current understanding that radioactive Potassium-40 decays to the stable form, Argon-40 with a half-life of approximately 1.25 billion years.  The same principle holds true for the other isotope dating methods.

suncorellationRadioactive decay occurs at a constant exponential or geometric rate.  The rate of decay is proportional to the number of parent atoms present.  There are some circumstances that can affect this rate such as magnetic fluctuations etc… But in general, this rate is felt by the vast majority of mainstream scientists to be a fundamental constant.   That was until August of 2008 Jenkins et. al., published a paper suggesting that the decay rate of radioactive elements is related to the Earth’s distance from the Sun.  In other words, the decay rates show annual changes that closely reflect the Earth’s distance from the Sun (see illustration).51  Of course, the detected variation is no more than 0.2% of the published rates, but this paper is still quite interesting since such a correlation was never suspected before.  If magnetic fluxuations or other influencing forces are strong enough, radiometric decay rates could be much more significantly effected.  In short, the assumption that decay rates are immune to outside influences isn’t as solid as it once appeared to be.

However, if one does assume a constant decay rate, and if one starts with an originally pure sample of “parent element,” then the proportion of parent to daughter tells us the number of half-lives, which has been used to find the supposed age of igneous rocks.  For example, if there are equal amounts of parent and daughter isotopes, then one half-life has passed.  If there are three times as many daughter isotopes as parent, then two half-lives have passed, and so on.

Most minerals, which contain radioactive isotopes, are in igneous rocks. The majority of scientists today assume that the dates they give indicate the time the magma cooled.  This also assumes that there was no initial daughter isotopes contained in the magma at the time of cooling.  The assumption is that at least a great majority of the isotope present was the parent isotope.  This parent isotope then degraded to the daughter isotope over time.  Consider the following statement by Dalrymple, a well-known geologist:

The K-Ar method is the only decay scheme that can be used with little or no concern for the initial presence of the daughter isotope. This is because 40Ar is an inert gas that does not combine chemically with any other element and so escapes easily from rocks when they are heated. Thus, while a rock is molten, the 40Ar formed by the decay of 40K escapes from the liquid.2

So, according to Dalrymple, K-Ar or Ar-Ar are the only methods that have little or no concern for the presence of initial daughter isotopes.  This means that all the other radioisotope-dating methods (excepting isochron methods) are brought into serious question.  The reason for this is because unless the initial ratio of parent to daughter isotope is known, the current ratio would be worthless as a means of determining elapsed time.  A rock cannot be said to be millions or billions of years old if there is no way of knowing what the original composition of the rock was at the time that it was formed.  The assumption for the K-Ar method is that all argon escapes at the time of rock formation because argon is a gas while potassium is not.  Likewise, the other non-isochron dating methods, such as uranium-lead, also fall short because who is to say when the “zero date” was when there was only parent isotope and no daughter?  Because of this problem, it might be a significant error to simply assume that all original isotopes present in a given rock were parent isotopes.

The primary assumption upon which K-Ar model-age dating is based assumes zero 40Ar in the mineral phases of a rock when it solidifies. This assumption has been shown to be faulty. CEN Tech. J., Vol. 10, No. 3, p:342 1996

Lets now consider how fossils are dated with many of these methods, such as the potassium-argon method.  The mineralized fossils themselves are not directly datable by radiometric techniques.  The sedimentary rock that buried them is also not datable.  If there is some igneous rock fragments in that sedimentary rock layer, these fragments are dated, most commonly, by the 40K/40Ar dating method described above.  It is assumed then that the fossil is as old as the igneous rock fragment that it is buried with.  Aside from the zero-date problems noted above, one might consider the possibility that the fossil might not be as old as the sediment that buried it in the first place.  For example, lets say that my pet dog dies.  I decide to bury it in the back yard.  Is the dog as old as the dirt that I buried it in?  Likewise, who is to say that some fossils were not buried in sedimentary material that was weathered from significantly more ancient formations?

History of Radiometric Dating (Part 1 of 15)

By Sean Pitman M.D.
Source: Detecting Design

History of Radiometric Dating is 1 of 15 parts to Radiometric Dating Methods.

history datingAt the time that Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be 100 million years old. By 1932, it was found to be 1.6 billion years old. In 1947, science firmly established that the earth was 3.4 billion years old. Finally in 1976, it was discovered that the earth is “really” 4.6 billion years old… What happened?4

The study of geology grew out of field studies associated with mining and engineering during the sixteenth to nineteenth centuries.  In these early studies the order of sedimentary rocks and structures were used to date geologic time periods and events in a relative way.   At first, the use of “key” diagnostic fossils was used to compare different areas of the geologic column.   Although there were attempts to make relative age estimates, no direct dating method was available until the twentieth century.

However, before this time some very popular indirect methods were available.  For example, Lord Kelvin had estimated the ages of both the Earth and the Sun based on cooling rates.  The answer of 25 million years deduced by Kelvin was not received favorably by geologists. Both the physical geologists and paleontologists could point to evidence that much more time was needed to produce what they saw in the stratigraphic and fossil records. As one answer to his critics, Kelvin produced a completely independent estimate — this time for the age of the Sun. His result was in close agreement with his estimate of the age of the earth. The solar estimate was based on the idea that the energy supply for the solar radioactive flux is gravitational contraction. These two independent and agreeing dating methods for of the age of two primary members of the solar system formed a strong case for the correctness of his answer within the scientific community.

This just goes to show that just because independent estimates of age seem to agree with each other doesn’t mean that they’re correct – despite the fact that this particular argument is the very same one used to support the validity of radiometric dating today.  Other factors and basic assumptions must also be considered.

Of course, Kelvin formed his estimates of the age of the Sun without the knowledge of fusion as the true energy source of the Sun. Without this knowledge, he argued that, “As for the future, we may say, with equal certainty, that inhabitants of the Earth cannot continue to enjoy the light and heat essential to their life, for many million years longer, unless sources now unknown to us are prepared in the great storehouse of creation.” This last statement was prophetic. There were indeed powerful and unknown sources of energy fueling the Sun’s energy output.

The same is true of the basis of Kelvin’s estimate of the age of the Earth. It was based on the idea that no significant source of novel heat energy was affecting the Earth. He believed this even though he did admit that some heat might be generated by the tidal forces or by chemical action. However, on the whole, he thought that these sources were not adequate to account for anything more than a small faction of the heat lost by the Earth. Based on these assumptions he at first suggested an age of the Earth of between 100 Ma and 500 Ma. This estimate was actually reduced over his lifetime to between 20 Ma and 40 Ma and eventually to less than 10 Ma.

Of course, later scientists, like John Perry and T. H. Huxley challenged Kelvin’s assumptions. Perry, in particular, a noted physicists and former assistant to Kelvin, showed that cooling calculations using different but equally likely assumptions and data resulted in ages for the Earth of as much as 29 Ga. After this came to light, Kelvin admitted that he might just as well have set his original upper limit on the age of the Earth at 4,000 Ma instead of 400 Ma. Of course, this was a close as Kelvin ever came to publicly recanting his position. Later, after radioactivity had been proven to be a significant source of the Earth’s internal heat, he did privately admit that he might have been in error.

What is especially telling about this whole story is the conclusion of the absolute truth of the conclusion based on premises that are weak, or at least not adequately demonstrated. Chamberlain (1899) pointed out that Kelvin’s calculations were only as good as the assumptions on which they were based.

The fascinating impressiveness of rigorous mathematical analyses, with its atmosphere of precision and elegance, should not blind us to the defects of the premises that condition the whole process. There is perhaps no beguilement more insidious and dangerous than an elaborate and elegant mathematical process built upon unfortified premises. – Chamberlain 1899b:224

Following the discovery of radioactivity by Becquerel (1896), the possibility of using this phenomenon as a means for determining the age of uranium-bearing minerals was demonstrated by Rutherford (1906).  In his study Rutherford measured the U and He (He is an intermediate decay product of U) contents of uranium-bearing minerals to calculate an age.  One year later Boltwood (1907) developed the chemical U-Pb method. These first “geochronology studies” yielded the first “absolute ages” from geologic material, which seemed to indicate that parts of the Earth’s crust were hundreds of millions of years old. (Boltwood’s ages have since been revised).

During this same period of time Thomson (1905), Campbell and Wood (1906) demonstrated that potassium was radioactive and emitted beta-particles.  The first isotopes of potassium (39K and 41K) were reported by Aston (1921).  Kohlhorster (1930) reported that potassium also emitted gamma radiation. Following theoretical arguments by Klemperer, Newman and Walke (1935) on the existence of 40K, which radioactively decayed to 40Ca by beta-emission, Nier (1935) discovered 40K and reported a value of 8600 for the 39K/40K ratio.  Newman and Walke also suggested the possibility that 40K could decay to 40Ar.  However, it was Von Weizsacker’s (1937) argument, based on the abundance of argon in the Earth’s atmosphere relative to the other noble gases (He, Ne, Kr, and Xe), that 40K also decayed to 40Ar by electron capture.  As a test, Von Weizsacker suggested looking for excess 40Ar in older K-bearing rocks. By combining Von Weizsacker’s argon abundance arguments with Kohlhorster’s observation that potassium emitted gamma-radiation, Bramley (1937) presented strong evidence that potassium underwent dual decay.  Thompson and Rowlands (1943), using a cloud chamber, confirmed that 40Ar was the decay product of 40K undergoing electron capture.  The absolute confirmation that 40Ar was the decay product of 40K came when Aldrich and Nier (1948) measured significantly increased 40Ar/36Ar ratios on argon extracted from potassium-rich minerals relative to the atmospheric 40Ar/36Ar ratio.  The rapid development of the K-Ar dating method soon followed.

The 40Ar/39Ar variation of K-Ar dating grew out of iodine-xenon dating studies of meteorites by Jeffery and Reynolds (1961).  In these studies the isotopic ratios of all the noble gases (He, Ne, Ar, Kr, and Xe) of neutron-irradiated meteorites were measured.  This led to the discovery of 39Ar, which is derived from 39K by Merrihue (1965). The first 40Ar/39Ar dating results were presented in a paper by Merrihue and Turner (1966). Further development of the 40Ar/39Ar method by Mitchell, (1968), Brereton, (1970), and Turner, (1971) evaluated the interfering argon isotopes derived from potassium and calcium (36ArCa, 39ArCa, and 40ArK) and determination of the respective correction factors [ (36Ar/37Ar)Ca, (39Ar/37Ar)Ca, and (40Ar/39Ar)K].  The first applications of the 40Ar/39Ar dating method of terrestrial rocks compared total fusion 40Ar/39Ar ages with conventional K-Ar ages (Mitchell, 1968; Dunham et al., 1968; York and Berger, 1970; Dalrymple and Lanphere, 1971).

It is felt that the 40Ar/39Ar dating method offers a significant advantage over the conventional 40K/40Ar dating technique for several reasons.  However, the most significant advantage of the 40Ar/39Ar dating method over the conventional 40K/40Ar method is the ability to step-heat samples to higher and higher temperatures until the sample is fused, and calculate and ages for each step.  The 40Ar/39Ar step-heating method provides information on the internal distribution of potassium relative to argon.  The first 40Ar/39Ar step-heating studies of terrestrial samples were by Fitch (1969), Miller (1970), York (1971), Lanphere and Dalrymple (1971), and Brereton (1972).1

Rubisco: No longer burdened with evolutionary baggage

By Timothy G. Standish
Source: Geoscience Reports

Photosynthesis uses light energy to harvest atmospheric carbon dioxide (CO2) and make carbohydrates while also releasing oxygen (O2) from water back into the atmosphere. Rubisco catalyzes the step in photo- synthesis at which energy harvested from light is used to attach CO2 to a five carbon sugar ribulose 1,5-biphosphate. Ribulose diphosphate carboxylase is the full name of Rubisco. Because it is the single most abundant protein in plants, Rubisco may be the most common protein on earth.

Inside the leaves of plants, the fixing of CO2 to ribulose 1,5-biphosphate occurs efficiently as long as CO2 concentrations are high and O2 concentrations are low. However, when the conditions are reversed and CO2 concentrations fall and O2 levels rise — a common event on hot sunny dry days — Rubisco may substitute O2 for CO2 placing an oxygen onto rubulose 1,5-biphosphate. This process is called photorespiration which, unlike normal respiration, does not produce energy. The product of photorespiration is split into two components. The tree carbon component, 3-phosphoglycerate, is recycled in the Calvin Cycle portion of photosynthesis. The two carbon component, phosphoglycolate, is ultimately oxidized and lost from the photosynthetic process.

Some plants — for example, grasses — are well adapted to prevent photorespiration and thus thrive under hot dry conditions when other plants cannot. However, the affinity of Rubisco for O2 appears to be the same in all plants, and on average plants lose about a quarter of the carbon they harvest in photosynthesis back into the atmosphere as a result of photorespiration. The difference in plants that can live under warmer, more arid conditions is that they possess com- plex mechanisms to pump CO2 into photosynthesizing cells, thus avoiding the conditions that result in photorespiration. These adaptations reduce, but do not entirely eliminate photorespiration.

This raises the question of why Rubisco would be so poorly designed that it sometimes wastefully incorporates O2 instead of CO2. A standard text- book explanation has been that mal- adaption on the part of Rubisco reflects the evolutionary history of the earth. In the past the atmosphere must have had lower oxygen concentrations and higher CO2 concentrations and thus there was little selective pressure to choose more discriminating forms of Rubisco.1

This story has been called into question in a recent paper published in the Proceedings of the National Academy of Sciences by scientists at the University of California Davis.2 In this paper Rachmilevitch et al. demonstrate that nitrate assimilation is dependant on photorespiration. Nitrate (NO3-) is the most commonly available form of nitrogen in temperate well-aerated soils3 where C3 plants (those most susceptible to photorespiration) are commonly found. Because nitrogen is vital for production of amino acids and thus proteins, Rach- milevitch et al. suggest that photorespiration, rather than being left over evolutionary baggage, is vital for plant growth and survival.

One observation explained by the work of Rachmilevitch et al. is that plants do not grow as well as expected when exposed to higher CO2 concentrations.4 While multiple factors are involved, apparently a major factor is CO2 induced repression of photorespiration, thus nitrogen assimilation is inhibited and plants are rendered incapable of producing the proteins they need to grow. This illustrates how well designed Rubisco really is to ensure that plants can grow under current environmental conditions. Given this new realization, Rubisco represents yet another in the long series of examples of “poor design” that turn out on closer exami- nation to be in fact very well designed. Not only does poor design not logi- cally exclude a Creator5; it turns out that solid examples of poor design are hard to find in nature.

The mechanism suggested by Rachmilevitch et al. for conversion of NO3- into a usable form illustrates that addition of O2 to ribulose 1,5 biphosphate in photorespiration is one step in an elegant multistep mechanism to reduce the highly oxidized nitrogen in NO3- to ammonia. In this process, malate,6 a byproduct of photorespiration, is exported from chloroplasts to the cytoplasm where it reduces NAD+ to NADH which in turn reduces NO3- to NO2-. Whether or not this explanation stands the test of time, it illustrates the complex and integrated nature of what must be occurring to couple photorespiration with NO3- assimilation.

Poor design in Rubisco can now be added to the growing list of failed Darwinian arguments from ignorance. These arguments have the form: we don’t know why nature does this, so it must be bad design. In this case, the argument was that we don’t understand why plants do photorespiration, so photorespiration must represent bad design. Other examples of the failure of this kind of thinking include the now-abandoned arguments that vestigial organs and junk DNA represent evolutionary baggage. As our knowledge of nature grows, things once thought to represent refuse left over from evolutionary history now appear to be very well designed for their task. This appears to be an ongoing trend which, should it continue, calls into question all Darwinian arguments based on ignorance of the workings of nature.

A Darwinian apologist might argue that the design now apparent in Rubisco is exactly what one would expect in such an important and ubiquitous protein, especially given evidence that the first Rubisco evolved over 3.8 billion years ago.7 However, this explanation exposes the infinitely plastic nature of evolutionary explanations. On the one hand poor design is exactly what evolution would predict; and on the other hand, well adapted designs are exactly what evolution would predict.

In reality, Darwinism appears to offer little insight into why nature exhibits good or bad design. On the other hand, the creation offers a clear explanation for why good design might be expected in nature and suggests strongly that where flaws are evident this is the result of malfunction, devolution — not baggage left over from a process of constant refinement and improvement as evolution suggests…when it is not suggesting exactly the opposite.

Natural Selection

By Sean Pitman M.D.

natura1According to evolutionary theory, natural selection is the driving force behind the process of evolution. The mindless processes of nature are thought by most modern scientists to be the creative forces the mold and govern everything that we see in and around us – to include all life forms. Truly then, Nature is the Creator. Nature is a mindless god of sorts. But, by what power does this god create all the fantastic variety and creativity that we see around us? – especially when we look at the workings of living things?

As far as the variety of life forms are concerned, the theory of evolution proposes that the nature created and is still creating the huge variety of living creatures via random genetic mutations that can be selected as advantageous or disadvantageous in particular competitive environments over vast spans of time. Nature is said to do this by preferentially selecting those life forms that survive and pass on their genes to their offspring the best. This “natural selection” uses competition for survival. The production of slightly different offspring provides the opportunity of sorting out advantageous traits from the less advantageous ones. More and more traits are added or subtracted in this way until a creature’s offspring are fine tuned to the particular environmental niche that they occupy. The whole process is often referred to as, “The Survival of the Fittest.” This is rather a neat idea, but exactly how does it work? Does natural selection tend toward genetic diversity or stability?

natura2A famous example of natural selection is England’s peppered moth (Biston betularia). Despite the current debate on the actual methods of the original study it is still a good example to illustrate natural selection. In the original study by H.B. Kettlewell, he was wondering why the peppered moth was more commonly dark than specimens that had been collected and saved from earlier times in England’s history. The peppered moth had been generally much whiter in color, but now it was much blacker. Why this change? It was suggested that when the industrial revolution arrived in England, the pollution had turned the bark of the trees a much darker color. Since light colored moths are much easier for birds to see on a dark background, they were preferentially eaten. However, the few darker moths survived better to pass on their darker coloring to their offspring. Pretty soon, there were lots of dark moths and very few light colored moths – or so the story went. In reality, England’s peppered moths do not generally rest on tree trunks (despite what some of the staged pictures produced by Kettlewell seem to suggest). However, subsequent studies seemed to confirm Kettlewell’s main hypothesis that England’s peppered moths were in fact getting darker over time. Still, this is still not necessarily an example of evolution in action.

father1Gregor Johann Mendel (1822-1884), an Austrian monk and a contemporary of Darwin, is generally recognized as the father of modern genetics and the study of genetic inheritance. Mendel showed conclusively that the genes (alleles) of creatures contained built-in abilities for inherited variation that are not dependent upon mutational changes but upon the built-in variety potential of a given gene pool of allelic options. He found that some allelic traits were “dominant” while others were “recessive.” Each trait was coded for by two separate allelic codes on equivalent positions on two separate but matching chromosomes. As long as one of the codes was the dominant code, it would block out the other code. So, an individual with two different codes for the same allelic positions would express the dominant trait. For example, if one parent had two dominant color codes and the other parent had two recessive color codes at the allelic position coding for hair color, then the offspring would all be the dominant color (i.e., brown vs. blond). However, if each parent had one dominant and one recessive color code then, according to the calculated odds of inheritance, three-quarters of the offspring would be dominant in color and one-quarter recessive (The offspring with both dominant and recessive codes would express the dominant color. Only those offspring with both recessive codes would express the recessive color). If both parents had both recessive color codes then all the offspring would have the recessive color.

So you see, such a method of option swapping at set locations on chromosomes allows for a huge variety of expressed morphologies or phenotypes. However, since the codes only swap with each other at set locations, the body parts themselves maintain their usual orientation with each other. In other words, genetic recombination will not cause an eye to grown on a baby’s foot or an ear to grow inside its stomach. The swapping of options is random, but limited as to exactly where the swapping can and cannot take place. For example, it works much like interchangeable parts on a car. If I don’t like the hubcaps on my car, I can swap them out for new ones that still fit in the same location, but they may look very different. I can also swap out the steering wheel for a very different looking one, but it still fits in exactly the same place on the car and it does pretty much the same job.

This same thing happens during genetic recombination. One particular position on a chromosome might code for eye color. Many different interchangeable parts or codes for eye color have the potential to occupy and “work” in this spot. But, codes for eye color would not work so well if they were placed where the code for nose size is supposed to go. This would be like trying to put a hubcap where the carburetor is supposed to go. Some parts are simply not interchangeable, and the process of genetic recombination knows this. So, during the process of genetic recombination, the genes or allelic options themselves have not been changed, just their expression (i.e., The hubcaps, steering wheels, carburetors, and all other part options are still the same. It is just that some parts are used to make some car “expressions” while other part types are used to make other car “expressions”).

natura3There are many different variations and complications, but this is the basic idea that Mendel discovered. In other words, great diversity can be had through a selection process that picks between previously established traits or allelic part options. This is why breeding has been such a thriving occupation for centuries. Selective breeding based on the potential of genetic recombination alone (for the most part) is responsible for the great varieties of cats, dogs, horses, and even humans, as well as a host of other breeds – to include Darwin’s famous finches. Mendelian genetics and other types of genetic recombination are the primary reason why children do not look exactly like their parents or each other (unless they happen to be twins). Children from the same set of parents do have variations in their appearance and yet these variations are dependent upon nothing more than different expressions and mixes of the same identical gene options from both parents (the parental gene pool of options). Note carefully thought that this process (as it ideally works) has nothing to do with mutation so nothing new as far as the “gene pool potential” is concerned is created. No unique genetic functions are evolved during this process (i.e., An exchange of one type of hubcap for another type of hubcap that already existed in the pool of hubcap options does not make the pool of options change).

A mutation, on the other hand, is a change in a specific gene that was not originally inherited. The different white and black colors in the peppered moth are clearly the result of genetic recombination at work. The peppered moth gene pool already contained codes for both the light and the dark colors of peppered moths. Nature did in fact play a role in selecting the most common color from this pre-established pool of options but it did not create the options in this case (at least not in observable time). So, such examples of changes do to genetic recombination cannot be used as examples of evolution in action because clearly, they are not making anything new as far as the gene pool is concerned. For example, no matter how much selection pressure is applied to England’s peppered moth, a green peppered moth will never evolve via genetic recombination alone. Why? Because the code for green color is not in the peppered moth’s genetic pool of options (i.e., If there are no green hubcaps at Wal-Mart, where I do my hubcap shopping, my car will simply have to do without green hubcaps). The only way to get this option to come into the gene pool of options is for random mutations or mistakes in the genetic code to create this option de novo.

natura4The problem is that random mutations generally limit existing genetic functions and so nature almost always selects against the changes produced by random mutations. In other words, if an individual sustains a mutation in one of its genes, this mutation lessens the function of this gene most of the time. With a less functional gene, the creature has a higher probability of competing less well than peers. This mutant creature and its offspring will most likely die off because of this deficiency. Of course, after the die off occurs, this particular mutation would be removed from the gene pool of options for this “kind” of creature. In this way, nature in fact limits mutational change to the genes of most creatures. For many creatures, such as mammals, mutations are fairly rare to begin with; on the order of one mutation per gene per 100,000 generations (1). Understand also that the majority of even this relatively small number of mutations are detrimental in nature (The ratio of detrimental vs. beneficial mutations is thought to be around 1000:1 – with the rest being “neutral” as far as function is concerned). One major problem is one of how to eliminate the detrimental mutations as fast or faster than the much lower rate of beneficial mutations. For humans this is turning out to be quite a mysterious problem. In fact, it seems that the human species may be deteriorating at an alarming rate. Consider an excerpt from a fairly recent Scientific American article entitled, “The Degeneration of Man”:

According to standard population genetics theory, the figure of three harmful mutations per person per generation implies that three people would have to die prematurely in each generation (or fail to reproduce) for each person who reproduced in order to eliminate the now absent deleterious mutations [75% death rate]. Humans do not reproduce fast enough to support such a huge death toll. As James F. Crow of the University of Wisconsin asked rhetorically, in a commentary in ‘Nature’ on Eyre-Walker and Keightley’s analysis: “Why aren’t we extinct?” (4)

Such problems certainly are a challenge for natural selection to keep up with and get rid of much less overcome to use in some fantastically beneficial way. Clearly natural selection is a real force of nature, but it is limited by the genetic options that it can pick from. New options can only be added through mutation of the original options – and this seems to be very limited at best.

natura5But what about some famous mutational benefits that have survived? What about sickle cell anemia for example? Sickle cell anemia is caused by a single “point” mutation of the hemoglobin molecule. This molecule is responsible for oxygen transport in red blood cells. When it has the mutation that causes sickle cell anemia, it does not carry oxygen as well. It also has a tendency to “sickle” or polymerize into a shape that is inflexible and unable to pass through very small vessels called capillaries (2). This causes the individual with sickle cell disease a great deal of pain and eventually an early death. So, why has nature preserved or “selected” to maintain this mutation in our particular human gene pool of options? Nature has done this because of another even more deadly problem called malaria. Malaria is caused by a microscopic protozoan that lives part of its life cycle as a parasite in human red blood cells. However, the malaria parasite needs a specific oxygen concentration to survive. Those humans with sickle cell anemia cannot maintain the necessary oxygen level needed for the malaria parasite to survive. So, those with sickle cell anemia, or even sickle cell “trait” (one sickle cell allele – instead of the two possible sickle cell gene alleles) survive better in an environment where there is malaria. However, this survival comes at a high cost. They have a less functional hemoglobin molecule. A loss of function or a disruption of previous functions or interactions is far easier to achieve via random mutations than a new function that is not dependent upon the loss of or interference with any pre-natura6established functions or interactions.

The evolution of new genetic functions that relies on the disruption of pre-established functions is a quick and easy process that happens all the time. The evolution of antibiotic resistance to all the various antibiotics that we have developed is based on this process. The de novo development of the antibiotic function in a colony of bacteria is dependent upon the fact that all antibiotics are quite specific in their interactions with particular intra-bacterial target sequences. Any little disruption of the target sequence will interfere to one degree or another with the antibiotic’s interaction with this sequence. This interference results in equivalent resistance to the antibiotic. Obviously then, the ratio of interfering mutations involving this target sequence is very large when compared to the total number of potential mutations that could affect this sequence. This high ratio of what will “work” compared with what will not “work” creates a very small gap between what is and what might be more helpful in the current situation or “environment”.

The problem is that there are other cellular functions that are not dependent upon the disruption of a pre-established functions or interactions. For example, single protein enzymes act alone, without the need for the loss or interference of any other cellular function. Several such enzymes have been shown to evolve de novo in living organisms such as bacteria. However, given the much higher specificity of the average enzyme (as compared to antibiotic resistant target sequences), it is much harder to evolve a new beneficial enzyme than it is to evolve the much simpler antibiotic-type function. Some examples of enzyme evolution include the evolution of the lactase and nylonase functions in bacteria (3). However, such examples are extremely limited and highly constrained by both environment as well as the starting genetic real estate of the population of bacteria. Many if not most types of bacteria simply cannot evolve certain specific enzymatic function regardless of the size of their population, high mutation rates, and tens, hundreds, or even millions of generations of time. Of course, the problems only get worse from here on out. Functions of far greater complexity exist inside living cells. For example, many functions require the simultaneous action of multiple proteins interacting in a specified arrangement with each other. If it is difficult to evolve just one relatively simple enzymatic-type function, imagine how hard it would be to evolve any function of the level requiring such a specific multi-protein system as is used in various bacterial systems of motility (i.e., the flagellum – requires 50 or 60 unique proteins all working together at the same time in a specific orientation with each other). Interestingly enough, no such function that requires multiple proteins working in specified concert has ever been shown to evolve in real time. It just doesn’t happen even when all the required parts needed to produce some fabulously beneficial function are already present inside the same cell as parts of other systems of function. The problem is that the parts themselves, if left to themselves, just don’t know how to self-assemble to form much of anything. They need outside information telling them how to assemble in specified ways to produce higher and still higher levels of functional complexity. Without this outside information, in the form of pre-established genetic codes or the insight of an intelligent mind, the parts are no more creative in their interactions than a junk pile during an earthquake (even if that earthquake lasts for millions, billions or even trillions of years – - nothing more complex than a pile of random parts will be realized).

So, natural selection is a real force of nature. However natural selection is very much limited to a pre-established gene pool of options. Natural selection generally interacts with Mendelian laws and other laws of genetic recombination to create diversity. Mutations are almost always detrimental and are therefore selected against, as a rule, by natural selection. And, even the mutations that are beneficial are limited to the lowest levels of functional complexity. There simply are no examples of real evolution producing anything of the level of complex function that requires multiple proteins working in a specified orientation at the same time. Natural selection is therefore a force that generally acts against the other natural force of evolution (random mutations) and even at its best is not much of a help to the popular theory of evolution.
