Since the first discovery of the extinct Homo Sapiens and Homo Neanderthal, the question of which was the direct ancestor of our people has been hotly debated, due to the number of traits we shared with both. We now know, thanks to genetic evidence that every person on earth has roughly the same amount of genes from both species, with maybe a 0.01% more Neanderthal in some Eurasians, and about the same amount more Homo Sapien genes among Africans. So, what if instead of both species being driven to extinction by our ancestors, the two races either never cross breed, or cross breed less?
OOC: Just to clarify, the POD is extensive cross breeding between Homo Sapiens and Homo Neanderthal creating a third species which out competed both to extinction.
