Hated by both sides
The point is that if you want to argue that humans underwent biological, genetic change in order to adapt to a process by which the better pissheads got more totty then you need to show how that adaptation ended up presenting itself across all humanity. By the time humans are living on every continent, that’s a hell of a challenge. You either need a population that is small and isolated enough that a change in that population ends up being the basis for the whole species, or you need the adaptive pressure to present itself systematically enough that it somehow affects an entire dispersed species in the same way.
Wasn’t there a massive genetic bottleneck at some point way after the migration from Africa, presumably due to some near-extinction event? Perhaps the signalling drunkards slept though it.
