"The origin of these true Homo seiapns seiapns was in America based on the data coming from modern populations". Isn't it more likely that the origin was somewhere in North/Central Asia? I don't think there's any evidence for human presence across the Bering strait going back 100k, is there? Whereas there is certainly evidence for human presence at least 55 degrees north through Central and East Asia going way back beyond then. To alter your own comment a little, 'lineage loss in small populations in Asia and lineage retention in America could explain this rather plausibly'. "What I hypothesize (and this may change) is that at 45-40K a population different from 'anatomically modern humans' advanced into Europe and Africa from the east". I could go along with elements of that. In fact it ends up being remarkably similar to the 'regional continuity' theory. In other words human evolution is a product of backwards and forwards movements going back to when H. erectus (or something similar) first emerged. There was no sudden expansion of anatomically modern humans, just a series of genetic, cultural and technological expansions. It's ultimately impossible to draw a line and say, 'that's when we first became modern human'. Hence the huge disagreement as to when 'anatomically modern humans' actually emerged from Africa.
