    "that's news", FYI
    but it is you not I who are not following the logic of how that could be. Your suposition is not the only way that could be true.

    Humans originated in Africa. Waves of humans left Africa to populate the rest of the world.

    THe ancestors of Neanderthals left Africa several hundred thousand years ago. They adapted to a glacial climate and became the Neanderthals.

    Their cousins who stayed in Africa continued to evolve. Some became Homo Sapiens.

    60K years ago (?) some Homo Sapians left N. Africa and crossed into the middle east. Then, later, they crossed into Neanderthal lands in Europe. Neanderthals disappeared. Neanderthal groups apparently were smaller than HS groups and less dense/numerous. They were out competed and outbread...but also it turns out only in the last few years we know that after all We DID interbreed with them(so very cool).

    So Modern Africans who's ancestors never left Africa, as you can see, never got any Neanderthal genes (from Europe and the Middle East). Modern humans intermingled with Neanderthals in the Middle East and Europe and then those modern humans populated the rest of the world.

    One punch line for me is that for centuries (White) Americans had thought of Africans/African AMericans as inferior or worse (subhuman). Yet it looks like it is THEY that are the only ones who are PURE Homo Sapiens Sapiens straight back to the orgins of our species. For decades people thought Neanderthals were 'cave men" and backwards..but it is White Americans who have the "cave-men" genes.
    irony.
