It seems the last two big cover stories in Christianity Today covering evolution issues have completely ignored the many scientists and others who accept evolution as the best explanation for some things, but have serious doubts about it as the best explanation for all of biological history.  These articles ignore those Christians who doubt evolution based primarily on the scientific evidence, not theology.

The latest cover story deals with the biography of a theistic evolutionist and a young earth creationist.  No biography of Michael Behe who was taught theistic evolution growing up, but who came to doubt Darwinism as he delved deeper into the science.  Sigh.  Christianity Today is dumbing down the church and missing the most interesting questions.

Christianity Today also never reviewed Alvin Plantinga’s book Where the Conflict Really Lies: Science, Religion, and Naturalism, in which Plantinga devoted a whole section to Michael Behe’s design arguments, and had very positive things to say about them.  CT published an interview with Plantinga, but avoided all discussion of ID.

In the recent article, the author, Tim Stafford, asserts that Darrel Falk “has held to his plea for Christians to love and respect each other while advocating different points of view.”  Well, that is not quite right.  Falk has claimed elsewhere that he has a kind of “mission from God” to attack other believers:

With all respect for [Michael] Behe as a person, his science has turned out to be highly incompetent in the field in which he writes—biology.  Since he chose to take his science to non-professionals many of whom have not had more than one college course in biology (if that), you are correct: BioLogos needs to show that he, bless his heart, is professionally incompetent; one of our God-given tasks (to be frank this is the way we see it) is to demonstrate this to a public which (unlucky as they are) doesn’t have the biology background to know better.

When I asked Darrel Falk to explain how Behe was incompetent, he failed to do so.

I and others had some dialogue with Dennis Venema on the Biologos blog about his presuppositions in approaching the question of whether there could ever have been a single human couple.  It seems clear from the comments that Venema has a strong presupposition that God did not intervene supernaturally in the creation of Adam and Eve and did not intervene supernaturally in any significant way in the history of humanity from its origin until the Bible makes reference to miracles such as the virgin birth of Jesus.  I know of no theological basis for such a presupposition.  I have called this kind of position “Theistic Materialism” and discuss in more detail here.

Notice the questions that Venema avoids, and how he avoids any discussion of historical contingency in his comments.  Stephen Jay Gould did not dismiss such considerations, and observed the importance of distinguishing the methodology of the historical sciences from the methodology of experimental sciences.  An extended quotation of Gould on this topic is here.

Darrel,

In another thread, I asked you:

Bruce Waltke has stated that God “by direct creation made ADAM a spiritual being, an image of divine beings, for fellowship with himself by faith.”  It also seems possible that God intervened in human history to specially create or affect other human beings.

If God did what Waltke and others believe he did, how would this have affected the genetic evidence?  How would this affect the certainty of the historical conclusions we could draw from the genetic evidence?

You suggested that this was just like the YEC position that God created things with an appearance of age (with the implication drawn out by others that that would suggest that God was deceiving us).  I disagree, and here is why:

Does God heal?  What if a man prays that God will heal his wife’s breast cancer, and God responds by tweaking her BRCA genes?  What if the first humans lived 200,000 years ago, and God tweaked human genes once every 200 years to heal in answer to prayer?  That would mean 1000 changes to the human genes.  How would that affect our current calculations?  What if God intervened 5 times each year?  Now we are at a million changes.

If God does things out of his love, and there are SIDE EFFECTS that affect the human gene pool, God is not deceiving us.  We are deceiving ourselves by having too small an understanding of God and his work in history.  Job 38 is instructive as to the epistemology we should adopt.

You said in that, “we do take a firm position on the scientific fact that two people could not have been the genetic progenitors of all humankind.”

Your claim that it is a “scientific fact” shows a clear error in your scientific methodology or your scientific reasoning or both.  It is quite simply bad science.  It also seems to involve bad history, bad theology or bad logic, or all of the above.  Your claim may be a perfectly reasonable inference to draw depending on the assumptions that are behind it, but it is not a “scientific fact.”  Christians would do well not to make such errors in evaluating the evidence and in evaluating the certainty that we can have based on the evidence.

The methodology for the historical sciences must be different than the methodology for the sciences that involve repeatable, observable data.  I have never seen anyone at Biologos articulate the proper methodology for the historical sciences as well as Stephen Meyer (or even Stephen Jay Gould) has.

Hi pds,

Are you suggesting that God would heal the germline version of the genes in question, or merely the somatic ones? A tumor in the body would be somatic tissue. If divine genetic intervention is to be heritable it would need to be “healed” in the cells that make sperm or eggs (the germline). Often, the genetic state in the tumor is different from the germline (since it was mutations in non-germline cells that started the cancer). In that case, there would be nothing to heal in the germline – only in the soma (body). So, I don’t think your ideas really fit the biology of the situation.

Best,

Dennis

Dennis #8714,

Thanks for your reply.  You should not get too hung up on my specific example.  Based on your comment, a better example would be a prayer of a dying woman to protect her daughter and her children from the breast cancer that had killed her mother, her aunt, and now her.  I think my basic point is clear: God might intervene in history to do something that might have a side effect of affecting the gene pool.  There would be no intent to deceive us.

But let me ask you:  Are you absolutely convinced that God has never touched the human gene pool in all of human history?  If so, how?

I am not discounting your evidence.  I am only saying it leads to inferences that must be tentative.  Those inferences must then be weighed against other inferences from theology and philosophy.

Apart from theology, there are scientific reasons to be cautious of genetic evidence. Molecular phylogenies do not line up neatly with each other and do not line up neatly with morphological phylogenies.

This dialogue speaks for itself, methinks.  Biologos scientist Dennis Venema’s circular reasoning seems fairly obvious to “Rich” (and me), but not to others apparently.

Dear Dennis/Darrel:

Your argument seems to be:  If we back-reason based solely on our current knowledge of genetics, we must conclude that no single *human* couple could have been the parents of all of mankind.

May I ask a mischievous question?  Suppose that the best modern science ruled out the possibility that a female virgin could give birth to a male child by natural means.  Following your line of reasoning, would we not need to infer either (a) Jesus had a human father (hopefully Joseph!), and was the “Son of God” only by “adoption”? or (b) Jesus was born of a virgin, but that God overpowered the normal natural mechanisms to make this happen?

You will likely shy away from (a), for theological reasons.  But if you adopt (b), then you are saying that sometimes it is legitimate, even necessary, to presume that God altered the normal rules of genetics for his purposes, and that this inference is not offensive to “good science”.  So what then, would necessitate a naturalistic approach to Adam and Eve?  Couldn’t God have overpowered the relevant natural processes there, as well?  Wouldn’t you have a consistency problem in invoking a miracle for the Virgin Birth but denying special creation in the case of Adam and Eve?

I just read the Christianity Today article on Adam and Eve.  My short initial reaction: It is very one-sided. It functions as a promotional piece for Biologos, which is too bad. We need an alternative that actually helps Evangelicals to think and gives them the tools to do so.

The article largely uses the tired old method of pitting scientists against theologians. Unless it is scientist against scientist, it is a poor debate.

Fazale Rana, who is quoted in the article, commented on the article:

Honesty, it is poorly researched . . . They completely have ignored the fact that there is a strong scientific response . . . to the genomic evidence  . . .

I do not think the article quotes a single scientist who is formally trained in the methodology of the historical sciences.  When Darrel Falk and Dennis Venema state dogmatically that the human population “was definitely never as small as two,” their ignorance of the limitations of the historical sciences becomes clear.  Stephen Jay Gould understood the limitations, as I discuss here:  “We must be able to determine whether our hypotheses are definitely wrong or probably correct (we leave assertions of certainty to preachers and politicians) .”
