>>13438756Humanity evolved across at least 5 million years, switching entire continents multiple times over. The most recent expansion come from Africa, but by that point cousin sub-species were everywhere and could hardly be claimed as being African-descended. From these, early homo-sapiens drew important mutations developed by the million-year-old natives long since specialized for their own locale. The human evolutionary tree is complicated graph referencing itself time and time again, and it is almost weird to say homo sapiens, denisovans or neanderthals were ever distinct slices of humanity (almost, but of course geographic isolation made them distinct, but thy themselves had been fed by innumerable previous wave of human expansion).
The last wave out of Africa lacked proper grasp over linguistics, is what some seem to claim, so even more ever-more-rapid reverberating backscattering waves of human colonisation followed, indeed sometimes back into Africa. Probably the majority of what it now mean to be humn has its origins in Africa, but hat means little when that branch had it's original in India which in turn was dominated by movement from China and Greece (cf old hominid footprints in Greece) which in turn...
There is a picture somehere describing the ancestral flow of a recent group of S. America's and it is a tangleweb. Humans' looks like a ladder with multiple long parallel dominant strands (geographic isolates) suddenly criss-crossing into other strands suddenly.
Hopefully someone else can post actual references, but basically the idea that n African is simply your most-recent geographically-isolated ancestor is nonsense, for today's African himself can only claim partial shared ancestry with you and is rather more yet another sub-species,. Though most of what you are probably had it's last pit-stop in Africa.
