"They" have found OLDER Homo Habilis in Western Asia. They were there a very long time ~ and in fact, overlap the time period for Habilis in Africa.
So, it's now Out of Western Asia ~ with literally EVERYBODY showing up later on Inside Africa.
You can take those Sen people and run them North from Souf' Africa, or South from Western Asia, and you get the same thing with the mitochondrial DNA ~ to wit, Sen people as the closest living relative to the oldest modern humans, with everybody else derived from a Sen ancestral group (except for the Neanderthals and this other group in Asia).
There are like 14 different strains of mitochondrial DNA, with the Sen having the oldest variety. All Europeans and East Asians have the same. All the others in Africa are distributed around in different groups all over sub-Saharan Africa.
At the same time the demonstration that the Neanderthals, a well studied group, bred with the people who became Europeans and New Guineans is very important. Note that there are NO Neanderthals in Africa and their "type" arose BEFORE the Sen people and all their different variations. Modern black Africans are simply not ancestral in any meaningful sense to non-Africans. It's quite the reverse!
If I understand you correctly there were two migrations out of Africa one was the white race the other was the black race
am I correct in saying that?
That's the point I was trying to make. Your knowledge perhaps being that of an anthropologist (at least you sound like one), and mine that of an interested layman. I was aware of the later out-of-Asia theory, thence to Africa and elsewhere.
