Without getting into the papers you link, which at the moment are over my head or at least mystifying to me. and may remain so even if I spend more time on them -- we'll see--, I at least want to point out that the biblical time spans are quite sufficient to produce all the diversity we see on the basis of the simplest Mendelian genetics, which requires no mutations. I think I posted something to that effect here at one time, but if not I have posted on it at
my blog::
Parker describes how all the varieties of humans and animals are easily accounted for by simple Mendelian genetics combining a given built-in array of genes for various traits. The example he gave was of two parents with "medium" or "average" skin color, expressed as AaBb, with the capital letters representing the darkest and the lower case the lightest, saying that EVERY shade of skin that we see on earth can be produced from those two parents, from the darkest African (AABB)to the lightest European (aabb). When you think of every other trait as genetically expressed by the same formula, it becomes clear that an enormous variety of combinations would produce an enormous variety of types or varieties or races -- of people and animals of all kinds -- which would become characteristic of groups as they migrated and became geographically isolated from one another.
I go on to discuss there, and I know I have also argued it here, that the bottleneck of the Flood is misconstrued in terms of what happens NOW when there is a bottleneck. But what we see now is the result of a great deal of genetic reduction in all genomes since the Flood so that with a bottleneck we often get extreme homozygosity such as is seen in the cheetah and the elephant seal, both products of severe bottleneck or founder effect. But 4300 years ago there should have been a lot more heterozygosity for all traits remaining in all genomes than we see now, so that although a bottleneck would severely reduce that heterozygosity and produce much more homozygosity it would not be anywhere near the extremes such a bottleneck can produce today, leaving a great deal of genetic diversity to play itself out.
So, when it is argued that you don't SEE the signs of a bottleneck that would have occurred at the time of the Flood all you are saying is you don't see the signs that we see occurring NOW, but a bottleneck then would not have produced those same signs. There would have been a lot more genetic diversity left.
Maybe I'll try to deal with the links eventually.
