Yeah, I don’t think they would have been like modern slaves but more like bully/bullied relationships where those at the bottom aren’t forced to do labour but get targetted for various forms of abuse, including sexual, which would have sometimes resulted in a child.

They probably wouldn’t be abused by everyone in the group. Other apes like chimps show sympathy to individuals that get picked on by more dominant individuals, so I’d expect some of us were like that back then, too. But other apes also demonstrate that some individuals can just be assholes or otherwise decent but can get in bad moods.
