We always hear that Neaderthals were primitive, but if what you posted is true, then wouldn’t suggest that Europeans and Asians - if they have the higher rate of Neaderthal DNA - have been such dynamic and accomplished peoples perhaps because of that Neaderthal DNA?
Exactly.
It may have been our encounter and mixing with Neanderthal that gave us the higher IQ's we have today. We are the product of the best of the Modern Human/Neanderthal combinations.
