It's useless to take sides until the evidence is in, but mitochondrial DNA points toward the out-of-Africa idea.
The Out of Africa idea as currently propounded, which says that as recently as some 80 to 140 thousand years ago, persons deceptively called "modern humans" came out of Africa, and took over the world, replacing any earlier members of genus Homo that might have been there before, with no very significant admixture/intermarriage with said premoderns....
While this idea might be FALSE, it is hardly one that is congenial to traditional Darwinism or evolution. Quite the contrary, it begs almost for the intervention of Celestials both to produce [by genetics] the "modern humans," and then to give them UFO rides to settlement sites worldwide!
