It’s been a long time since I’ve been in Anthropology class, but this isn’t something we were taught academically. Cultural Anthro is all theory-based, academics get paid to publish theory arguments. Imo, biologically, women carried babies, men didn’t, there would have been associated cultural roles to accomodate this as successfully as possible. The idea that it’s popular theory this meant men hunted and women gathered is just sensationalist. It’s niether competely wrong nor completely right. There are elements of both throughout many cultures. It’s the idea that it’s all or nothing is wrong.
