Well in the Flood story there were eight people left after the flood to populate the world, but only two chimps. I wonder how that would explain the chimps having more genetic diversity when they started with a smaller gene pool in the first place. The Noah story helps not a bit here . . . sorry.
There's nothing quite like a gross over-simplification that fails its own supporting theory upon inspection.
The replicative cycle of chimps is shorter than the typical human. There would have been many more generations of chimps than people in the intervening period from a common singularity greatly exceeding the distinctions of four to one. Try again, and no, I am not a Biblical literalist.
Please see the scripture in post 19. Chimps are clean animals so they were taken by sevens, male and female. So there were 14 Chimps, not 2.
Likewise there were 3 breeding couples of humans. Noah and his wife had only three sons so his (and her) genes are represented in each of those couples. So you really only have the genetic makeup of one family and 3 other people. (who as noted in later posts were probably closely related anyway)
