They say Otzi had 4-4.5% Neandertal; I have 2.7%, which is average for Euros with my profile. Asians have higher percentages, up to 4%, so Otzi isn’t exactly off the scale.
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?
