III. When: Ancient or Recent?

As we’ve observed in the preceding section, using DNA sequences to function as a clock is not straightforward. In theory, just like the ticks of a clock mark off the passage of time, the transmission of another 60 DNA mutations from parent to offspring should be able to mark the passage of another generation. However, knowing how much time has passed requires knowing when the clock — whether mechanical or biological — actually started ticking. As we observed above, some (probably most) DNA differences may not represent mutations at all; they may have been supernaturally created in Adam and Eve from the start — e.g., Adam and Eve would have been created with genetic differences. Thus, when we’re evaluating the billions of DNA letters in our cells and trying to determine when the differences began arising, it’s as if we were asked how long a clock has been ticking — but then were told that the clock has at least four hands instead of two.60

Therefore, to use DNA as a clock to measure when humanity began requires a very careful accounting of all potential means of genetic change and all potential genetic starting points. In other words, the only relevant DNA clock to the human origins debate is one in which evolutionists and creationists agree on the mechanism by which DNA differences arise as well as on the number of starting points from which DNA differences can arise.

Only one candidate DNA clock currently fulfills these criteria. Again, the vast majority of the billions of DNA letters in our cells do not lend themselves to a head-to-head comparison. Both sides may claim that the data fits their view, but claiming that the data support a view to the exclusion of the other is very challenging (as illustrated in the previous section).

Conversely, creationists and evolutionists agree on the origin of DNA differences in a tiny subsection of DNA (~16,559 DNA letters long) contained in the energy factories of our cells, called the mitochondria. Mitochondria and mitochondrial DNA (“mtDNA”) are found in both males and females, but only females appear to pass on mtDNA to their offspring. In other words, we each received our mtDNA from our mother, and our spouses received theirs from their mothers. Each of our children in turn did not inherit their father’s mtDNA; they inherited their mother’s.

Evolutionists agree that the current mtDNA differences among modern humans are traceable to a single woman in the past, whom they label “Eve.”61 However, they insist that this woman was part of a population of humans, not a single pair. This conclusion arises, not because of anything inherent to the mtDNA data, but because of the data from the billions of letters in the rest of the DNA sequence and the evolutionary presuppositions that we discussed in the previous section.

From a biblical perspective, all humans trace their ancestry back to Adam and Eve. However, because mtDNA is maternally inherited, YE creationists would agree with evolutionists that mtDNA differences today are traceable to a single woman in the past — Eve (both creation and evolution refer to her with the same name). Furthermore, both evolutionists and creationists would agree that modern mtDNA differences are the result of copying errors (i.e., mutations). Unlike the 3 billion DNA letters of DNA in the cell’s nucleus that come in two versions, mtDNA comes in only one version — effectively, the mother’s version. Hence, mtDNA differences arise via copying errors and were not created in Eve.

Thus, on the question of the origin of mtDNA differences, evolutionists and creationists are in complete agreement, except for one point — when this maternal ancestor lived. (Again, the evolutionary claims about this woman being part of a population have nothing to do with the mtDNA data itself; the population claim is imposed from the outside on top of the mtDNA data.)

To summarize up to this point, when we’re discussing mtDNA, both origins views hold to a single starting point. Because mtDNA comes in one version, not in two versions like the 3 billion letters of nuclear DNA sequence, both origins views also hold to copying errors (mutations) as the sole source of DNA variety (i.e., YE creationists do not believe that God created different mtDNA versions in Eve). Thus, mtDNA comparisons are one of the few type-1 experiments that can actually be performed to answer the question of when humanity began, and since the rate at which mutations occur in mtDNA has already been measured, this experiment can be performed right now.

To use mtDNA as a clock, we simply use this measured mutation rate to make testable predictions based on either the evolutionary timescale or on the YEC timescale and then compare the predictions with the scientific, observed facts. In other words, rather than starting with mtDNA differences in the present and then dialing the clock backward to see how long it would take to get to Eve, we’re going to go backward in time to the beginning under each model and predict what would have happened if the clock were allowed to run forward to the present. Specifically, we will assume for sake of argument that humans originated a long time ago (180,000 years ago under the evolutionary model62) or recently (4,500 years ago under the YEC model,63 representing the end of the Flood — see technical references for technical genetic reasons why the Flood date rather than the creation date was chosen).64 Then we will predict how many mtDNA differences should have accumulated in the timeframe specific to each model, after which we’ll compare these predictions to the actual number of differences in the current human population.

Thus, by multiplying the measured mutation rate of mtDNA65 by 180,000 years or by 4,500 years, we can make testable predictions about the timescale of human origins. Comparing these predictions to actual mtDNA differences at the global scale reveals a result that strongly contradicts the evolutionary timescale and confirms the YEC timescale (Figure 2).66

Figure 2. Comparison of origins predictions to actual human mitochondrial DNA differences. Differences were predicted by multiplying the measured mitochondrial DNA mutation rate by 2 and by the model-specific time of origin (e.g., for evolution, 180,000 years was used; for creation, 4,364 years was used as the (post-Flood) time of origin). The height of each column represents the average number of differences that would have accumulated under the model- specific time of origin (“Evolution” and “Creation”), and the black lines spanning the top of each column represent the full statistical range of each prediction, not the standard deviation (e.g., the lines represent the maximum best possible guesses under the evolutionary or creation timeframes). The height of the “Actual” column represents the average DNA differences in Africans today, and the black line spanning it represents the standard deviation. African DNA differences were used instead of non-African differences because Africans are the most genetically diverse group alive today and because evolutionists posit that Africans evolved first.

After 180,000 years, humans would have accumulated over 2,000 DNA differences (range = 1,220 to ~4,700)67 via the process of mutation to mtDNA. In just 4,364 years,68 humans would have accumulated only 30 to 114 mutations.69 Currently, about 78 differences exist on average in African populations (i.e., the most genetically diverse of all the human ethnic groups), with a maximum difference of ~120. Clearly, the YEC timescale accurately predicts the number of DNA differences that we observe today, while the evolutionary timescale predicts numbers an order of magnitude higher. Similar results hold true in animal species, as illustrated in Figure 3.



 

 

Figure 3. Comparison of origins predictions to actual animal mitochondrial DNA differences. Differences were predicted by multiplying the measured mitochondrial DNA mutation rate by 2 (roundworms, fruit flies) or by 1 (water fleas), and by the model-specific time of origin (e.g., for evolution, the time appropriate to each organism was used; for creation, 6,000 years was used as the time of origin). The height of each column represents the average number of differences that would have accumulated under the model-specific time of origin (“Evolution” and “Creation”), and the black lines spanning the top of each column represent the full statistical range of each prediction, not the standard deviation (e.g., the lines represent the maximum best possible guesses under the evolutionary or creation timeframes). The height of the “Actual” column represents the average DNA differences today, and the black line spanning it represents the range of differences (where appropriate).

These findings represent much more than an isolated, irrelevant data point in the bigger creation/evolution debate. As we observed above, mtDNA is one of the only arenas in which a straightforward type-1 experiment can be performed — one of the only arenas in which we can judge the scientific validity of the creation model versus the evolution model. Furthermore, performing this mtDNA experiment in a wide variety of animal species leads to the same conclusion: the biblical view of earth history is correct.70 Thus, the evolutionary timescale runs into trouble not only on the question of human origins but across a much wider swath of biological life.

Implicit in these calculations was the assumption that the mtDNA mutation rate has been constant with time. We made this assumption since it forms the basis for the entire millions-of-years paradigm in the evolutionary model. When evolutionists claim that the earth or the universe are ancient, their methods assume that the geologic or astronomical processes that they observe today have occurred at a constant rate throughout the history of the earth or universe.71

For decades, YE creationists have pointed out the arbitrary nature of this assumption,72 especially in light of the global Flood element of the YEC model of geology.73 Essentially, YE creationists have correctly identified the entire millions-of-years paradigm as nothing more than a type-3 experiment. In short, the evolutionary argument about the age of the earth and of the universe work only if the assumption about constant rates of change is true. Change that assumption and the entire paradigm collapses.

Thus, by assuming constant rates of genetic change in our calculations, we made the calculations overly generous to the evolutionary view. The fact that the evolutionary predictions could not be reconciled with reality even under generous assumptions makes the explanatory dilemma for evolutionists all the greater. If they claim that rates of genetic change were different in the past, they’ve just undermined the foundational assumption of their entire ancient universe/ancient earth view. If they do nothing, they are left with a glaring contradiction between predictions and facts. Hence, these mtDNA results have implications for the evolutionary view far beyond biology, and they make the evolutionary paradigm even harder to maintain in a scientifically consistent and coherent way.

Perhaps the evolutionists will invoke natural selection to explain why their predictions do not match up with facts. In other words, perhaps humans have fewer genetic differences than predicted under the evolutionary model because natural selection eliminated a number of copying errors that arose in the past. This hypothesis would be worth exploring — but only if it leads to testable, falsifiable predictions.

Summary

In summary, there is no genetic evidence to support an ancient origin for mankind. The DNA differences in the billions of DNA letters in the cellular compartment termed the nucleus are easily explicable from two people in the last 6,000 years (see previous section), and the mtDNA differences observable today are all the more explicable (Table 4; Figure 2). The mtDNA arena of comparison also happens to be one arena in which a type-1 experiment can be performed, and the evidence strongly contradicts the evolutionary timescale while confirming the YEC timescale. Since these results assumed constant rates of genetic change, and since evolutionary geology and astronomy also depend on the assumption of constant rates of change for their millions- and billions-of-years conclusions, these genetic findings throw into confusion these two fields of physical science as well. Genetically speaking, mankind appears to have originated only a few thousand years ago.

Again, the success of these initial genetic results gives us confidence that we can predict mtDNA mutation rates for other species, and we are willing to test these predictions in the lab. In fact, we invite our evolutionary colleagues to join us so that we can perform a type-1 experiment as accurately as possible. If our evolutionary colleagues are unwilling or unable to make and test a falsifiable prediction, why should we view their claims as scientific rather than pseudoscientific?

IV. Where: Africa or Ararat?

The mtDNA results discussed above hinted at the one element of human origins that we have not explored in detail — the timing and geography of the origin of African people groups. On the question of geography, creation and evolution are largely in agreement — except for the origin of African people groups. Evolutionists posit that Africans evolved first and then gave rise to the non-African groups.74 In contrast, YE creationists posit the simultaneous origin of the major ethnic groups very soon after the dispersion at the Tower of Babel.

The genetic aspects of the evolutionary claim rests on a technical aspect of mtDNA comparisons. Both evolutionists and creationists use software to visualize the number of DNA differences among various individuals or ethnic groups, and one of the most common visualization tools is the creation of phylogenetic or family trees. Naturally, this implies a genealogical relationship among those connected on the tree, but, in the software employed, ancestry assumptions are not necessary. The tree simply depicts the number of DNA differences in a visually striking way.

When the evolutionists draw trees, they of course assume common ancestry regardless of the species compared, since one of the foundational tenets of evolution is universal common ancestry of all species on earth (i.e., all plants, animals, and humans are descended from a single common and microscopic ancestor). Not surprisingly, when evolutionists draw family trees of the human ethnic groups using mtDNA comparisons, they include chimpanzee DNA.75 This resultant tree — which evolutionists interpret as genealogical relationships — shows some of the African branches splitting off first (about 120,000–180,000 years ago, as we alluded to in section III) followed by non-African groups later (about 50,000 years ago).

Even if you omit the chimpanzee DNA from the comparison and draw the tree using only modern human ethnic groups, it is still obvious that African ethnic groups have about twice as many mtDNA differences among them as do non-African ethnic groups. If you assume that the rate of mtDNA mutations is constant with time, the fact of greater mtDNA diversity in Africans implies that Africans have been around longer than non-Africans.

However, implicit in this conclusion is a technical assumption about the mtDNA mutation rates. To measure these rates empirically, scientists must use pedigrees,76 which means that the units are reported in terms of mutations per generation. To convert these units to absolute time (i.e., mutations per year), scientists must make an assumption about how many years pass per generation. Evolutionists implicitly assume that the generation times (time from birth of parent to birth of child) across all ethnic groups are the same.

However, marriage data from the United Nations suggests that this assumption is not valid (Table 5).77 On average, African females marry earlier in life than non-African females. About 32% of African women are married by ages 15–19 whereas only 12% of non-African women are married by the same age. This roughly three-fold difference disappears at later ages (e.g., about the same number of African and non-African women are married by their 30’s and 40’s), suggesting that the generation time in Africans might be about twice as fast as the generation time in non-Africans. Since mtDNA is passed on maternally, these data imply that some African ethnic groups have twice as many mtDNA differences because twice as many generations have passed in their lineages as compared to non-African lineages.

The data we presented in figure 2 made predictions for a variety of generation times (e.g., 15 years to 35 years). Under none of these generation times could the evolutionary model correctly predict the amount of DNA differences observable today. In contrast, the YEC predictions correctly predicted the African mtDNA differences under the assumption of a higher generation time (e.g., assuming a generation time of 15 years, the YEC model predicts 69 to 114 DNA differences in 4,364 years, which captures the average mtDNA differences — 78 — present today among Africans). The mtDNA differences among non-Africans (about 49, not displayed in figure 2) were predictable under the YEC model by assuming a generation time of 25 years (predicted range of differences = 41 to 69). Thus, the fact of higher mtDNA diversity in Africans does indeed appear to be due to their earlier age of marriage (and, presumably, of child-bearing), not to their supposed ancient evolutionary origin.

These data notwithstanding, evolutionists have also tried to buttress their out-of-Africa claims with data from the 3 billion DNA letters in the genome of the cell nucleus that we discussed previously — the main engine of heritability and diversity among humans. Specifically, Africans have more DNA differences among these 3 billion letters than non-Africans (only about 1.25-fold more), and they have more combinations of these differences (in technical genetic terms, linkage disequilibrium is lower in Africans).78 To the evolutionist, these facts are consistent with an ancient origin of humans in Africa, and a more recent population bottleneck in their descendants who left Africa to found the modern non-African ethnic groups.

Again, these claims rest on assumptions of identical generation times among African and non-African ethnic groups, an assumption that is not borne out by current data. In addition, it appears that Africans reshuffle (e.g., in technical terms, recombine) their DNA at higher rates and/or in different places than non-Africans, which would explain their extra combinations (e.g., lower linkage disequilibrium) of DNA — a conclusion that even the evolutionary community concedes.79

About the only genetic arena in which evolutionists can still hope to find evidence for an early origin of mankind out of Africa is in the Y chromosome — the chromosome unique to males, which is passed from fathers to sons. Current data indicate that African men have about twice as many Y chromosome differences as non-African men.80 However, the rate at which the Y chromosome changes — either by mutation or by a process termed gene conversion — has not been published for Africans. We predict that African Y chromosomes will change twice as fast as non-African Y chromosomes. Conversely, if evolutionists are confident in their out-of-Africa model of human origins, we invite them to make a counter-prediction — and then test their ideas with us in the lab.

In summary, there is no straightforward genetic evidence for the origin of mankind first in Africa. Evolutionists reach this conclusion genetically by assuming human-ape common ancestry and by assuming that the generation times of all ethnic groups are identical. In the context of the origins debate, the first assumption represents circular reasoning, and the second assumption does not match published data. Africans reproduce earlier than non-Africans and reshuffle their DNA faster/in more places than non-Africans, and both of these facts appear sufficient to explain the data that we observe without invoking separate times of origin for the various people groups in existence today (Table 6).
