I will be engaging this idea sometime more in the upcoming weeks, but wanted to point out that there is a potential challenge that exists here. The challenge is related to how Christian schools/various organizations have statements of faith. Presumably, Dr. Craig would agree with Biola’s (or at least has to sign a contract most likely saying he agrees) statement of faith given his job there.
Specifically Biola has written in their statement of faith (which Dr. Craig likely cannot agree with):
Therefore creation models which seek to harmonize science and the Bible should maintain at least the following: (a) God providentially directs His creation, (b) He specially intervened in at least the above-mentioned points in the creation process, and© God specially created Adam and Eve (Adam’s body from non-living material, and his spiritual nature immediately from God). Inadequate origin models hold that (a) God never directly intervened in creating nature and/or (b) humans share a common physical ancestry with earlier life forms.
So I wonder if any ‘honest’ look at the data must come to predetermined conclusions. If Mark Noll was on to something in his Scandal of the Evangelical Mind, or if Pete Enns is on to something when he summarizes, [the scandal of the Evangelical mind is that doctrine determines academic conclusions then we know exactly what kind of conclusion Dr. Craig must arrive at. I know this atheist blogger has written a lot about Dr. Craig and others, but there is something here worth listening to or at least being aware of I think.
So by faith, this position is not an intellectually honest one, where one must reject all evidence for common descent a priori and defend the special creation of Adam. It seems as if the evidence against a bottneck of two was given at least lip service, but was easily dismissed citing something he read of yours and then proposing an idea perhaps you can speak to of - modern humans don’t necessarily share common descent, all of the similarity between us and other primates could be due to simply inheriting some genetic material from Neanderthals or Denosvians? It also seems like he misunderstood your particular model @swamidass. I want to be charitable to his inquiry that he actually could come to certain conclusions, but Dr. Craig admits (~12 min or so) that his focus is first to go to the Biblical text, see what conclusions he might be allowed to permit- and then turn back to scientific inquiry and fit scientific inquiry into neatly packaged permissible theological boxes.
