Well, it certainly “subverted” (or atleast was part of the effort to subvert) all the prior theories of human racial separation. It allowed every moron on earth to bleet out pat phrases like “there’s more genetic diversity within Africa than outside Africa” and have literally zero idea what they’re talking about, or what their useful idiocy is being used to achieve. “Out of Africa” basically exists to subvert all notions of racial differentiation, since “we wuz Africans 6 gorillion years ago”.

I take less issue with the actual data the theory is based on (basically attempting to reconstruct a history of haplogroup migration), than I do the broad and absurd popular delusions that have been constructed on that theory and data. But one piece I’ll point to debunk the broadest strokes of the theory is to point to the up to 20% of the subsaharan genome which doesn’t appear in any other genome on earth (also referred to by the popsci label “ghost DNA”). Out of Africa has no plausible mechanism by which this reality could exist while also maintaining its core notions.
