Sept. 20, 2007 -- A team of researchers, including Herman Pontzer, Ph.D., assistant professor of physical anthropology in Arts & Sciences, has determined through analysis of the earliest known hominid fossils outside of Africa, recently discovered in Dmanisi, Georgia, the former Soviet republic, that the first human ancestors to inhabit Eurasia were more primitive than previously thought

So what have we got to date?
A hominid going OOA perhaps around 2 million BP – HH? – exploring the middle East, crossing a wide mountain range (the first mountain range crossing in hominid history?), and ending up in Georgia, 1,8 million BP, in isolation from the hominids it descended from, turning into early HE.
The oldest HE's in Africa are also 1,8 million BP, afaik.
Were those oldest HE's in Africa really Dmanisi Man who had returned?

Hmmm. Well I suppose a few could return and become a population but why would they return? Its not an easy journey from Africa to the Caucasus mountains and back again.
Maybe, genetic Adam and Eve actually originated in the Caucasus and spread to all points on the earth from there. It is a convenient location for access to europe, africa and asia.

The OOA Club will hunt you down and kill you for that, Monk!

There's no telling how many generations may have passed before that return. Climate change and other factors may have accounted for it. A million years is a really long time.

Why would they return? They didn't, they simply spread out, after a few thousand years there would have been no memory of Africa, and if they needed new territory and were blocked to the north, or where ever, they would have moved in another direction. If that was south, so what?

Right Dig, I think that's the main point.

How many times did the ice advance and retreat during that million years, I wonder?

Right. And so, 1000ky old ancestors would be found at other equally distant regions as well. If the hypothesis is correct, it would predict similar finds in other regions.

They call that the Multi-regional Theory.
