Good point. There is significant evidence that patriarchal dominance hierarchies spread because they were so destabilizing.

Patriarchy spread because it was destabilizing. “Egalitarian populations are eventually able to stabilize, not because of density-dependent growth but because fertility, mortality, and resource productivity achieve a balance.” Counterintuitively, the fact that when inequality arose it was so destabilizing caused these patriarchal societies to spread by creating an incentive to migrate in search of further resources.
