Two Beautiful Books: Science... err... correction: Nature and Scripture (Appendix)

In the previous six posts, I put forth what I believe to be a biblical view of science and Scripture, and I gave some advice on how to hand apparent conflicts between "science and religion," "science and Christianity," "science and faith," or however we label the tension. In that series, I said several times that I was not trying to tell you what to believe on certain sub-topics of science and Christianity (e.g. the age of the universe) but trying to teach you how to think biblically about science and consistently as a Christian. Well, there are a number of sub-topics on which I am sure you would like more information, so in this post I will list a number of resources that I think you may find helpful. But, if you still cannot find what you are looking for, feel free to comment and ask about something I do not mention here.
I hope these are helpful to you as you think biblically about science and consistently as a Christian. Remember, feel free to comment and ask for a recommendation on a topic not listed here. I may not have a good one that I have read, but it never hurts to ask.

Trajectory Towards the Biblical Account and Adam and Eve

First, to all my friends and readers, let me apologize once more for not writing at all in the past couple of months. Things have been quite busy lately and while I love to write, it is has had to take a backseat to my new call as associate pastor at Grace Covenant Presbyterian Church. This past weekend, however, God brought me through a huge milestone--ordination approval by our presbytery--which means all the time I was spending studying has been freed up. I am sure it will not take long for other things to fill it, but I hope one of those is writing regularly again.

Those of you who have read my blog for a while know that I like to follow and comment on the debate about the existence of an historical Adam and Eve. There has been a lot of genetic research in the past few years, which has brought this debate into the popular media. There are some who argue that the genetic evidence shows that Adam and Eve could not have been historical individuals. There are even some Christians that make this argument. I have argued, however, and still hold that their interpretation of the genetic evidence is guided by an a priori commitment to Darwinian evolution and that the data can be interpreted within an orthodox, biblical framework with equal validity. I would also argue that new research over the past couple of years has confirmed that validity of a biblical interpretation of the data. What I want to do in this article is look at the trajectory of the scientific data as a whole over the past several decades and show how it is converging towards the biblical account of human beginnings. (It might be helpful first to read this article or this article for background on the genetic evidence discussed below, though not absolutely necessary.)

The latest data comes from a few papers published in Science in August. All three of these (here, here, and here) argue that all male and female genetic lines can be traced back to two individuals--y-chromosomal "Adam" and mitochondrial "Eve"--who could have lived at the same place and time, which counters many previous arguments that claimed the "genetic Adam and Eve" could not have known each other at all. (Now, evolutionists are quick to argue that these two individuals were not the Adam and Eve of the Bible, but a man and women from a large population of the first humans whose genes just happened to continue on while all others died off. I argue against that here and Dr. Rana of RTB makes a case against that here.) Now, the dating of the original pair in these papers is not consistent with each other, but given the large margin of error/uncertainty when it comes to these types of calculations, it is understandable that their dates might differ. And, when all their error bars are taken into consideration, they could all overlap in the 100,000-150,000-year range. What is important is they all indicate that the genetic Adam and Eve may have lived at the same time and in the same place. (These studies confirm a few early studies from the end of last year and the beginning of this one, which Dr. Rana of RTB discusses here.)

These papers are the most recent body of scientific data, which is part of a long history of evidence that is converging towards a biblical account of human origins. Let me explain. About 30 years ago, the popular interpretation of the scientific data was that humanity originated about two million years ago and from independent pockets of populations of lesser species of the genus homo throughout the world. This multiregionalism data was difficult if not impossible to square with the biblical account of creation, so it was easy to dismiss the Bible as "anti-science" and irreconcilable. But, as data from archaeology and the fossil record was refined, as microbes and human parasites like lice were studied, and as genetic data began to be introduced, the date for humanity's origin became much more recent and the number of independent locations from which humanity may have originated became fewer and fewer. Eventually, multiregionalism was abandoned by the majority of the scientific community in favor of the Out-of-Africa model. In this model, it is believed that humanity originated in East Africa recently (about 100,000-150,000 years ago) and eventually migrated to the Middle East. So, the data has moved from multiple, independent origins of humanity millions of years ago to one fairly recent origin possibly in or about East Africa. In fact, the margin of error could put humanity's origin as far east as the Mesopotamia region or as far south in Africa as modern-day Ethiopia. This convergence towards the recent origin of humanity in one location fits very well with the biblical data that puts humanity's origin in a single location near the Mesopotamia region. Furthermore, in the past 20 years, human migrations have been studied, and the evidence points to a great migration that began fanning out from the Fertile Crescent of the Middle East into all other areas of the earth. This migration event fits quite well with the Tower of Babel described in Genesis 11. In fact, even paleolinguistics is finding evidence for a single proto-human language, which also fits well with the Tower of Babel. And, finally, as discussed above, the data for a genetic Adam and Eve once showed that they existed thousands of years apart from one another, but that data is converging towards the two existing at the same time and in the same location. There is, of course, a margin of error in these dates (and, in fact, I argue here that biblically we might expect them not to match), but even with that error, the data is converging more and more towards a single, recent pair of humans from which all humanity comes.

So, about 30 years ago there was virtually no way to square the data with Scripture, but most Christians wisely did not abandon their Bibles and waited. As we waited, the scientific data and dominant interpretation moved away from very old, multiple, independent human origins towards a single, recent point of origin with a single pair of humans, which is consonant with the biblical account. The migration data shows that even more recently humans began aggressively fanning out from the Middle East into the rest of the world, which is consonant with the biblical account. And, paleolinguistics is uncovering evidence for a single proto-human language for all mankind, which is also consonant with the biblical account. In sum, the trajectory of the past 30 years of data has begun to coalesce towards the biblical account of human origins and migration. What was once virtually impossible to reconcile with the biblical account can now be easily harmonized with Scripture. Scripture said it first, and the scientific data is finally catching up.

Are there questions still to answer? Certainly. Fitting the Flood in, for example, is more difficult (though certainly not impossible, as I argue here). But, I do not think we should expect to have all the questions answered yet. We have been given snapshots of the earliest part of human history in Genesis 1-11, we are getting even broader snapshots of the earliest part of human history through the scientific data, and the trajectory of the data is pointing towards what the Bible has been teaching all along. Given time and patience, I believe the questions will be answered and the Bible will continue to demonstrate its veracity. We should find this harmony and trajectory very encouraging, but really, it is also exactly what we should expect. God created the world and wrote Scripture, which means as we collect more data from the scientific enterprise and interpret that data properly, it will show us that the Bible has been right all along. That is what we should expect. That is what we have seen over the past few decades. And, that is what we will see in the future.

In the Meantime...

As I mentioned in the last post, I am pretty busy right now studying for ordination exams, preparing to move to Blacksburg, etc., which means I have not had much time to write. So, I was thinking that in the meantime I would give you some links to some good reading. So here you go:

Okay, that is more than enough to keep you busy for a while.

Dr. Fazale "Fuz" Rana in Atlanta

My friends, you have seen me write a number of posts about evolution, science and religion, Adam and Eve, and icons of evolution. It should be quite clear by now that I do not believe the scientific data supports an evolutionary view of our world's history, and I am not the only Christian with a science background who thinks this. On Thursday, March 21, 7:30 pm at Perimeter Church, Dr. Rana from Reasons to Believe (a man with far more knowledge in this area than I) will give a lecture on science and the biblical account of creation. It would be well-worth your time, if you can make it.

Much Ado About Nothing: More Adam and Eve Genetic Discussion

"If we take into account that, again, the difference is calibration, this result is compatible with all the other results that have been generated with regard to the y-chromosome data, and that data, I believe, supports a biblical understanding of human origins. So, I don't see this study as a challenge to our model or a challenge to the previous work that has been done. So, this is 'much ado about nothing,' in my opinion, all due to differences in clock calibration." ~ Dr. Fazale "Fuz" Rana

You may have seen articles like "African-American's Y chromosome sparks shift in evolutionary timetable" or "Don't call him 'Adam': South Carolina man’s genes help date first man" in the popular news in the past few days. These articles discuss some recent research based on the y-chromosome (y-c) of a South Carolina man, which appears to be genetically very different from the y-c's of most other men in the world. The difference of his y-c from the rest of ours pushes the date for modern humans back more than 200,000 years earlier than all previous studies have estimated. At least, that is what the researchers claim in their report on their findings.

Since I have written about the genetic research with regard to Adam and Eve in past articles (here and here) and argued for the historicity of the biblical account, I had planned to get the journal article on which these news articles are based and check out the data myself. However, a scientist whom I greatly respect--Dr. Fazale "Fuz" Rana--and who works for Reasons to Believe has already reviewed the data and reported his take on it in this podcast. I just finished listening to his evaluation of the research, and I think it is sound. I probably could not improve on it, so I recommend you go listen to what he has to say about it (the podcast is about 27 minutes long).

In sum, the crux of the whole issue is how these researchers calibrated their molecular clock analysis. (I have explained how molecular clocks work, and also discussed their failings, here.) They used a different calibration from every other bit genetic research that has ever been done. As a result, their research and date look significantly different from everyone else's. In addition, their date does not match the evidence from the fossil record, which is also a significant strike against them. If they had used the same calibration that everyone else uses, their date would have turned out to be slightly older than all previous research (and the fossil record evidence), but it would have agreed with all previous research within acceptable margins of experimental error. They argue that their calibration is superior, but they have no basis for making that assertion since there is no benchmark against which to measure molecular clock analysis except the fossil record, with which their date does not agree. What they have done is analogous to changing the calibration of your speedometer in your car and then trying to tell a police officer that you were not speeding based on your calibration. Neither he nor a judge is going to accept that your calibration is more reliable without hard, proven evidence. We should not accept this research unless it can show sufficient reason for overturning all previous research and the superiority of their calibration. Listen to Dr. Rana's podcast for a much more detailed explanation. It will be worth your time.

So, as Dr. Rana states above, this is really just "much ado about nothing." Until these researchers can prove with much more data the superiority of their calibration of molecular clocks, they have not overthrown the more generally accepted dates for Adam and Eve. Now, of course, evolutionists will say that those dates do not prove Adam and Eve at all, but I have argued elsewhere that the scientific data can be validly interpreted within a biblical framework that supports the historicity of the Genesis 1-3 account of human origins. No appeal to evolution is necessary to maintain a consistent view of the data, and this result does not change that.

Adam and Eve: A Tale of Two Cases

A couple of months ago I wrote a blog post about the historicity of Adam and Eve called "Who Was Adam?". In it I posted an excerpt from a blog of a friend of a friend and my response to her post where I showed that it is not the scientific data that calls into question the historicity of Adam and Eve but an evolutionary interpretation of the data. Since then, my post has been published on The Aquila Report, a Reformed news service, and I have talked about the issue at length with many people. I wanted to follow that post up with some clarification on the issue and further defend the biblical view. When the pertinent data is looked at from the two points (an evolutionary or biblical) of view we get a "tale of two cases".

First, I think we need to clarify a few things when it comes to the use of terms that one might hear thrown around when this issue is talked about. There have been several Christian scientists who deny the historicity of Adam and Eve because they claim that it "would be against all the genomics evidence that we’ve assembled over the last 20 years, so not likely at all..." (Dennis Venema, Trinity Western University) Some have flat out said that, "genetics convincingly shows that there was never a time when there were just two persons." (Darrel Falk and Kathryn Applegate, BioLogos) Francis Collins of the Human Genome Project says, "Adam and Eve as the literal first couple and ancestors of all humans do not fit the evidence." But what do they mean when they say, "genetics convincingly shows" or "against all genomics evidence"? What genetic evidence are they referring to? This is a very important question because a lot is riding on this evidence.

The problem with this generalized claim is that genetic evidence has four components to it. There are four types of DNA that gets lumped into the phrase "genetic evidence" and some of it makes the interpretation of Collins, Venema, et al. very uncertain (we will get to why that is below). The four types of DNA are as follows:
  • Autosomal DNA -- This is the DNA that makes up most of your genome and is a random combination of both of your parent's DNA. Since this autosomal DNA (atDNA) is a random combination of your parent's DNA (and their's is a random combination of their parents, ad infinitum) everyone's is completely unique. (This may also be referred to as "nuclear DNA" but that term is less precise.) For a good explanation of this type of DNA see this video.
  • Chromosomal DNA Types -- At the genetic level, what determines our sex is our chromosomes. Males have a X and a Y chromosome. Females have two X chromosomes. Each contains DNA: 
    • X Chromosomal DNA -- This is the DNA that makes up your X chromosome (X-c) that you get from your mother. It is a random combination of her two X chromosomes, so, like the autosomal DNA, it is unique, though it does not change as quickly as autosomal DNA. For a good explanation of this type of DNA see this video
    • Y Chromosomal DNA -- This is the DNA that makes up the male Y chromosome (Y-c) and it is only passed from fathers to sons. Since there is only one Y-c, there is no random recombination of genes so the only thing that can cause change in the Y-c is mutation. This means it often not unique and changes very, very slowly. For a good explanation of this type of DNA see this video.
  • Mitochondrial DNA -- This final form of DNA comes from the mitochondrial of your cells and it only comes from your mother. Male or female, it does not matter, your mitochondrial DNA (mtDNA) only comes from your mother. So, like the Y-c, there is no recombination of genes so the only thing that can cause change in the mtDNA is mutation. This also means, like the Y-c, it is often not unique and changes very, very slowly. For a good explanation of this type of DNA see this video.
We need to demand specificity from anyone making the claim that "genetic evidence" shows something. What kind of genetic evidence are they referring to? This will become important below.

Another term that gets used by scientists that often confuses people is "human". Now, you might think should be simple but it is not. An evolutionary biologist will use the term "human" to refer to any type of hominid from the homo genus like homo erectus or homo rudolfensis, not just homo sapiens (the taxonomic name for what species you and I are). This confuses the matter because scientists may refer to an ancient "human" fossil, footprint, or gene and they may not be referring to our species at all. This term also gives rise to the phrase "ancient modern human" used to refer to a homo sapien that lived in pre-historic times. This phrase not a contradiction in terms, but a further specification biologists use to refer to homo sapiens--a modern human species that lived long ago. I say this to make sure you aware of what is really being talked about when you read a science article in the popular news. If they say "human" they may not mean the species that you and I belong to and it may require more investigation on your part to figure out what they are really referring to. You can be sure that when I use the term "human" I mean a human like you and me, not any kind of animal that may have walked erect.

Second, we need to clarify that data that is being referred to by these scientists quoted above and that I will refer to below. There are two important types of data that come into play. The first I have already talked about in my previous post on this subject, and it is the mtDNA and Y-c data that shows that the entire human race can be traced back to one single mtDNA sequence for females and one Y-c sequence for males, a single pair of humans. (For a more detailed explanation of this see my first post on the subject.) As I just mentioned above, the mtDNA and Y-c change very slowly because the only mechanism for change is mutation. Therefore, scientist can trace the mutations of DNA take from all types of people throughout the globe back to a single first sequence for males and females. It is the single method of change--mutation--and the slow rate of change that makes this possible. (This would be impossible with atDNA, which is why it is important to know what kind of DNA someone is referring to!) The second type of data looks at the genetic diversity of humanity in the atDNA in humans. This data is drawn from mathematical models and attempts to take the present diversity of human atDNA and calculate how long it would take to get to the present state of diversity. These models have showed that in order for humanity to get to its present state of genetic diversity, it would have to have started out from a small population of humans (on the order of thousands) and not a single pair. These two sets of data appear to be in conflict, which is where our tale of two cases begins.

There are two possible ways of looking at this data. In these two interpretations different types of genetic data are given priority, which, again, is why it is important to know what genetic data someone is referring to when they say, "the genetic evidence says...".

Case #1 -- The Interpretation of Venema, Collins, et al.:
The mathematical modeling from the atDNA is given priority and it is assumed that humanity could not have originated from a single pair. This assumption is then imposed on the data that comes from the mtDNA and the Y-c. The question is then asked, "How could we have one ancient modern human mtDNA sequence and one Y-c sequence for all of us when humanity did not arise from a single pair?" Their answer is the "one lucky mother" hypothesis. They hold that there was originally thousands of mtDNA sequences and Y-c sequences in the first ancient modern humans but somewhere along the way all lines of these types of DNA died off except the one mtDNA and one Y-c that exist today in the present population. These sequences were from the "lucky" man and woman whose DNA was passed on while all other lines of DNA died out.

Case #2 -- The Biblical Interpretation:
In this case, the mtDNA and Y-c evidence is given priority because of the faults in the mathematical modeling and because of highly improbably "one lucky mother" hypothesis. In this case, the model is assumed to be incomplete (see below) and so it cannot be given the weight of mtDNA and Y-c tracking (which, remember, is a much slower process and much easier to trace backward). These ancient sequences are taken to actually point to a single man and single woman who were the progenitors of the entire human race. No special hypothesis is necessary for this interpretation, simply an acknowledgement of the limits of mathematical modeling with atDNA.

So, which of these cases seems more likely? It should be obvious by now that I choose case #2. Why? Well, I would like to expound upon the faults in the mathematical modeling and the "one lucky mother" hypothesis that I mentioned above:
  • First, the mathematical models, while sophisticated, do not take into account very important data and therefore the results are unreliable. Remember, with atDNA, there is a random recombination of parental genes so there are many more things coming into play than just mutations--many things which the model leaves out. For one, it assumes that environmental factors do not drive genetic diversity. Environmental factors are things like location, food supply, isolation, diseases, and anything else that can drive a population to change. Recent studies (like this one: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1766376/) have shown this this is a dangerous assumption and can greatly skew the data. These models also assume monogamy throughout human history, and we all know that this is not a valid assumption. Now, before you think the scientists are just being sloppy, consider how difficult it would be to include these factors into a model. How many sexual partners do you assume each human has? How do you know what environmental pressures were on an ancient human population for which we have no historical record? You cannot and so these models cannot realistically include these things. However, this just goes to show that their results should be used with great reservation. 
  • Second, the "one lucky mother" hypothesis has a critical flaw in it. If one assumes that ancient humanity began with a small population of thousands, then for this hypothesis to work one has to find a catastrophic yet very selective mechanism that will kill off all genetic lines except for one male's and one female's. It must be catastrophic enough to kill off thousands of lines and all their progeny and yet it must also be selective enough to kill off all but one for the females and one for the males. What event or process could be so terrible that it would kill off all genetic lines and yet also so selective that it would leave one and only one genetic line for each sex? Even theorizing about such a mechanism is nearly impossible. 
So, we must choose between case #1 and case #2. Case #1 puts more weight on mathematical models that are incomplete (see above) and must come up with a complicated mechanism for killing of all genetic lines but those of one male and one female. Case #2 acknowledges the issues with mathematical modeling and takes the mtDNA and Y-c data at face value without having to postulate extraordinary events to explain the data. If Ockham's razor means anything at all any more, we must acknowledge that case #2 is likely the correct explanation of the data.

What would keep intelligent men like the ones mentioned above from acknowledging that case #2 is more likely the correct explanation of the data? Presuppositions. We must remember that all of us look at this data with our bias that we bring to the table. I look at the data having faith that what Scripture says is historical and theologically important and therefore I choose case #2. Theistic evolutionists, like the Christians mentioned above, look at the data already believing that evolution is a fact and therefore choose case #1 because it fits that presupposition better. Am I any different from them in this regard? No, I readily admit that my bias influences my decision, but the point is that case #2 is 1) an equally valid interpretation of the data and 2) fits the data well with fewer complications and less reliance on incomplete modeling.

Scripture is my highest priority and I make no apologies for that, but it is also true that the data itself does not go against Scripture. It actually fits quite well with Scripture. This is what we should expect if we truly believe that God is the author of all truth, whether it comes from the infallible authority of Scripture or the scientific realm. For, as Paul says in Romans 11:36, "from Him and through Him and to Him are all things. To Him be glory forever. Amen."

Who Was Adam?

"Collectively, the consensus that emerges from this work indicates that humanity originated recently (about 100,000 years ago) from East Africa (near the location theologians ascribed to the Garden of Eden) from a small population. Amazingly, studies using mitochondrial and Y chromosomal DNA markers trace humanity’s origin back to a single man and woman." ~ Dr. Fazale ("Fuz") Rana, "A Burgoo of Human Origin Discoveries"

Today I responded to a post on the blog of a friend of a friend: Reflections on God's Word. In this post the author, Maria, talks about the move by some Christians, Francis Collins in this case, to dismiss Adam and Eve as historical figures. Dr. Collins, of the Human Genome Project, has looked at the genetic data and concluded that he believes Adam and Eve were not historical. Maria proceeds to flesh out the biblical implications of this in her post and points out why a historical Adam and Eve are important to orthodox Christian doctrine. Here is a portion of what she said:
...Collins has concluded from this study, as reported in a book he recently co-authored (The Language of Science and Faith), that “Adam & Eve as the literal first couple and ancestors of all humans do not fit the evidence”.

This assumption is disturbing on two accounts: First of all, those who support the findings and support theistic evolution minimize the impact of their assertions.  Second and more fraught with potential harm, is the implication for much of Biblical Theology and directly the trustworthiness of the Bible.  I will address the second of these issues.

The author of the “Christianity Today” article, Richard Ostling, correctly articulates what is at stake:
  • Humans’ unique status as image bearers of God
  • The doctrine of original sin and the fall
  • The genealogy of Jesus in Luke 3
  • Jesus’ teaching that all of the Old Testament points to Him (Luke 24)
  • Paul’s teaching that links the historical Adam with redemption through Christ

This issue is different from the debate among evangelical Christians who argue Old Earth vs. Young Earth.  In that arena, it is clearer that there are at least two possible interpretations.  The Bible refers to days (yowm) spent in creating the world.  In Hebrew ‘yowm/Strongs H3117’ can mean 24 hours, a year or a long period of time.  So the creation account is open to discussion without raising the trustworthiness of the Bible as an issue.

But if there is not a literal and historical Adam, then here are the implications:
  • God did NOT decide as a Trinitarian unit to make man in His image, male and female (Gen 1:27)
  • God did NOT have a conversation with Adam in Gen 2:16-17
  • Eve did NOT talk with Satan as serpent in Gen 3:1-5
  • Eve did NOT sin in Gen 3:6
  • No sudden guilt, shame and cover-up happened in Gen 3:7
  • No face-to-face encounter between God and the first couple took place in Gen 3:8-9
  • Adam & Eve did not try to pass the buck, playing the blame game in Gen 3:11-13
  • Gospel Hope was not first preached in Gen 3:15
  • No penalty for sin was announced in Gen 3:16-19, thereby explaining what is wrong with our world
...
You should go read the rest of her post here. It is a good biblical and philosophical defense of the trustworthiness of God's Word and Adam as a historical figure. Go ahead, go read it and then come back here..........

Now that you are back, I would like to share with you how I responded to her post. I thought it appropriate and necessary to respond from the scientific side of things as well. I wanted Maria, and all her readers, to know that it is Dr. Collins' interpretation of the data that is against a historical Adam, but his interpretation is not the only valid interpretation (as my quote in the beginning points out). Here is what I said:
Great article, I was directed here by a mutual friend–Adam Powers. I do not want to minimize the great points you made above but I also wanted to give a little perspective on Dr. Collins’ statement/opinion. I hope that this will encourage you in that you not only make a good Biblical and philosophical argument but that the scientific data are not against you.

Dr. Collins is truly a Christian, I believe, though I disagree with him about theistic evolution. One thing we must keep in mind with people like Collins who look at the genetic evidence is that they are looking at it with evolutionary presuppositions already in mind.

There are many studies that have emerged recently (like these: http://www.nature.com/nature/journal/v451/n7181/abs/nature06611.htmlhttp://www.sciencemag.org/content/319/5866/1100.abstract, http://www.sciencemag.org/content/277/5323/176.short) that indicate the mitochondrial DNA (mtDNA) of all humans can be traced back to one single sequence on the order of about 100,000 years ago. (We all get our mtDNA from our mothers only so even though I am a male my mtDNA still came from only my mother.) Other work done on the Y chromosome (Y-c) shows that all males can be traced back to a single Y-c (studies like this one: http://www.nature.com/nature/journal/v378/n6555/abs/378379a0.html) on the order of about 60,000 years ago.

Collins looks at this data and, because of his evolutionary presuppositions, thinks that this one sequence was just the “one lucky mother” whose DNA was passed on, while all the other DNA from the first “evolved” females died out. He interprets the Y-c data the same way. However, there is no evidence to favor this interpretation over one that looks at the data and says, “All humanity can be traced back to a single man and a single woman.” The second interpretation is simply much more difficult for Collins to fit into his evolutionary presuppositions, so he chooses the first. It is not the data that demands Christians throw out the idea of a historical Adam, it is Collins’ interpretation of it based on his presuppositions. The data equally support a historical Adam and Eve interpretation.

One might look at the dates and think, “Wait, how could the historical Eve be 100,000 years ago and the historical Adam be 60,000 years ago?” Scientists have asked a similar question. You might hear a geneticist say, “Did Adam know Eve?” and by that he means, “Did the woman who we get our mtDNA from know the man we get our Y-c from?” I think the Bible can easily fit well with this data. For us men, biblically who is the oldest male ancestor we could possibly trace our lineage back to? You might be tempted to say, “Adam” but is that really right? Actually, the oldest male we could possibly trace the Y-c back to is Noah. Why? Because of what is called a “population bottle neck”–the world’s population dropped to 8 people and then started over again. Noah and his three sons all had the same Y-c so there is no way to trace the Y-c beyond Noah farther back to anyone else. However, since it is reasonable to assume that Noah’s wife and his sons' three wives came from four different lineages, geneticists can trace the mtDNA beyond Noah. So, of course the dates would be different. In fact, the Bible (indirectly) predicts that these dates would be different!

Now, I am not trying to start an argument on your blog about the length of creation days (as you said, that can be debated without questioning the trustworthiness of the Bible) or whether or not the biblical genealogies are complete (which I also think can be debated without questioning the trustworthiness of the Bible). What I am trying to do is show that Collins’ interpretation of the data is not the only valid interpretation. It is equally valid, and I think more supportable, to say that human origins can be traced back to one man and one woman–Adam and Eve. So, far from ruling out a historical Adam, the genetic evidence supports it as one of the valid interpretations of the data.
I would like to suggest a book to those who would like to do more research on this topic: Who Was Adam? by Dr. Hugh Ross and Dr. Frazale Rana. It is an excellent resource by two men whose intellect far exceeds my own that dives deep into the scientific data and shows how modern discoveries do not discount and actually support a historical Adam (contra Dr. Collins).
