Someone here said collectivism is how we humans survived and progressed as a species. My question is, what "progress" are we talking about here? I don't see any such thing. For one thing, "progress" toward what? What seems to have happened about 10-12kya was a more stable climate (after the Ice Age) than any other time in H. sapiens history and some humans turning toward sedentism, staying in one place, rather than nomadic foraging and hunting. This was change but how it could be called "progress" I don't understand.
