Our ancient ancestors, like most primates today, lived in groups dominated by violent and aggressive alpha males. Yet over the course of our biological and cultural evolution, unlike our primate cousins, we learned to work together to counter those bullyboys, organising to diminish their influence.

Yeah, that's true, if you ignore essentially ALL of human history, in which violence and aggression were ever present, as was social hierarchy, that almost exclusively had a single male sovereign at the top.
