The suggestion I have heard from an anthropologist is that early Homo sp. were highly mobile, and that there was a lot of introgression among populations which is now very hard to reconstruct. I am not suggesting separate origins of the "same species." It is plausible that following introgression, some of the same traits were separately preserved in separate peripheral populations.
