That's a classic bioessentialist take that conflates practicality with inevitability. Sure, reproduction mattered—but so did defense, yet we don't see universal female combat exclusion even in antiquity. Scythians buried women with bows, Dahomey had all-female regiments, and Mongolian noblewomen led battles while pregnant. The "brutal world" had way more flexibility than pop evo-psych suggests.
The real kicker? Industrialization made maternal mortality plummet, yet militaries barred women from frontline roles until *the 21st century*. At some point "childbearing necessity" just becomes patriarchy with extra steps.
