Interesting clip.
Seems, due to archaeological evidence 'so far', that Warfare mostly existed in the Middle-East region.
Obviously, in such a sparce environment in need of farming - raiding was the new hunting of prey.
Civilisation: Humans preying on Humans.

Some good stuff throughout the clip.
Especially showing the Y-chromosome Bottleneck of the Caucasoid Races in Mid-East to Europe: where Warfare really decimated the Males and thus WEAKENING the Male genetic variation in the gene pools. Much like how a lot of animal species only have 'one' male for a number of generations. The Caucasoid Gene Pool went 'weak' in its masculinity.

...probably why the Mongoloid and Negroid races are referred to as the 'Dominant' gene as they had way more Y-chromosome variation across the board. Caucasoids, being weaker - were, on the male side akin to weak inbreeding.

Probably why DNA and how it works, in mixed race relationships now, see the Dominant Gene of the Darkie males as the superior combination and DNA will accommodate that. Don't be surprised if the Y-chromosome of Caucasoid becomes 'extinct'.
