Thats a really interesting fact to know, I woder how the theorists who promote “Out of Africa” handle that argument. Its sounds pretty solid to me.
So much of science today is driven by political correctness.
The climate boondoggle being the greatest modern example, and the Omana Junta ready to milk it for personal millions in Cap N Trade.
The Chinese are on to their approach because they too genuinely believe that China is the cradle of ALL civilization. I am glad they are giving the Africa origin
school a run for their money.
The indiginous Europeans must have found a way to live in the glacial periods, one wonders where they went.It will be found one day, likely under the Mediterranean Ocean.
There were OTHER groups, though, and during interglacials they also moved across Eur-Asia.
It is difficult to imagine that they couldn't move to Africa, and back into Eur-Asia.
The groups in Africa may well be "ancestral" at some level, but at the same time they've been on the receiving end of a lot of East-West and North-South gene flow ~ just like happens today.
They've developed their own optimal types for living in the Tropics.
