This was more my take. I mean, like women just sat there and said, “Whelp, there’s nothing to do. Let’s just take care of the kids.” It’s not some natural evolution. And, for all the people studying the past (in the past) to just be like, “Men hunt, women gather,” is ignoring how women ended up in those roles in the first place. The fact that they needed “evidence” of this is, before comming to that conclusion is…disappointing, but not surprising.
