Inspired by a comment from TheRationalizer, and Francis Collins’s admission that genetic data show that Adam and Eve could not have been the literal ancestors of all humanity, I had a great idea, which is mine and belongs to me. We can test another Biblical claim using genetics: the claim of the Great Flood of Noah (Genesis 6 and 7). The Bible says that every species on earth was reduced to either two or fourteen individuals, depending on whether you agree with Genesis 6 or 7 (I’d never noticed this discrepancy before).
For many species we can do genetic tests identical to the ones used by evolutionists to show that humans leaving Africa were reduced to a population of only a few thousand individuals.
The Flood Hypothesis, then, predicts that all species, some time around 10,000 years ago, went through a population bottleneck of either two or fourteen individuals. With a few assumptions, current estimates of genetic diversity can be used to test that claim. And I’m sure that the relevant data exist for many species, especially the fruit flies (Drosophila) I work on. From that data, you could determine if there was a bottleneck around then, how large it might have been, and the confidence limits around that estimate.
So, some bright young scientist out there: get on it. I can’t guarantee, though, that any reputable journal would publish your result. On the bright side, it wouldn’t take much work to figure this out.
Oh, and the problem doesn’t go away if you say that what Noah put aboard the Ark were not species but “kinds” or “sorts.” Those supposedly gave rise to all existing species, so the bottleneck problem still stands.
