@Lipetsk This is not historically correct though, Neanderthals were the peaceful ones and Sapiens were the vicious ones. That is why they went extinct.
@Fuko is that because the sapiens lived in warmer climates and developed muscles meant to hunt readily and chase animals over long distances within a short time frame? Whereas those in the colder climates stuck to caves and slower hunting styles. The differences in aggressive nature was a result of their environment. Although one would think that those used to warmer climates would be at a disadvantage in the colder north
