Your article was very interesting, but it didn’t mention the possibility of a genetic bottleneck after Homo sapiens was already dispersed into Asia and then eliminated from everywhere but Africa by the Toba volcano in Sumatra 74,000 years ago. It has been said that during the colder times after the explosion, the cold-adapted Homo neanderthalensis repopulated the eastern Mediterranean, to be followed much later by H. sapiens again, when the climate became warmer.
