Good book....very informative...unless you take the Out of Africa tripe politically correct POV
I don’ know where you/he gets this stuff from. But if Neanderthal and Homo Sapien interbreeding were strictly a European thing, then those of European decent would be remarkably different as a DNA level than non Europeans. That simply is not the case.
Either we ALL are, or none are. I’ll not argue against the fact that we all are. But I will argue that Europeans are NOT a species offshoot(mix of Neanderthal and Homo Sapien). And that the rest of the world are all Homo Sapiens.
