Define "Origin."
I believe "Out of Africa" is correct if and only if what you mean by
it is that a population living in Africa was best able to withstand
Toba, for instance, and spread out -- filling the vacuum. But, I also
have no reason to doubt that the origins of that African population
was Eurasia.
It's easy to miss, given the state of paleo anthropology, but the
present "Racial" makeup of Africa is irrelevant in a paleo context.
      ...the Bantu Expansion was more recent than the pyramids of
Egypt!
Doing the Google, Addis Ababa is over 3,000 miles to johannesburg, not
kilometers but miles, and it probably wasn't even the distance that
stopped them from moving!  No, it was disease. The British invented
the famous Gin & Tonic as a means for keeping their people alive!
There was a biological barrier, of sorts, for Europeans...
The "African" population in the Out of Africa expansion would have
been grouped with the Eurasian populations it stemmed from, NOT
the sub Saharan peoples. So they would have faced similar barriers.
They couldn't expand until #1 they acquired some immunity to sub
Saharan diseases and #2 their population density was sufficient
to warrant the bother.
This is probably why we still had archaic types in West Africa even
13,000 years ago. There just plain weren't that many of them!
If I'm allowed to delve even deeper:  They were culturally a
sexually selected group. They were a "Quality over Quality" breeding
strategy. Meaning, they weren't living anywhere near as long as
the Neanderthals to their north. But this, in the end, favored them.
As a sexually selected population they were viewed as far more
attractive than their northern counterparts, with greater sexual
dimorphism.
Also:  Being sexually selected, breeding like bunnies, meant that
they could bounce back significantly faster than other groups,
following cataclysms such as Toba.
They were the first on the scene, filling the vacuum.
So would their "Origins" be Africa? Eurasia? Where?
