>>81525032 (OP)not how it worked, you gotta get on gene-culture co-evolution frame like with fire
the culture it landed on is more or less consistent with both gender preferences even if not by free choices of everyone - the system was a regulated mate exchange, you trade women for resources, it increases probability of the next kid being yours and then switch mate to diversify genetics, mate exhcanges were based on value and trade of women and other goods but also based on feelings(you are willing to pay more for the ones you have eyes for) - falling in love for guys was a thing then too - disgust reaction exists to prevent falling in love with(which is guaranteed in proximity) to shit men for the ancient time. Tribes were on average ~50 people, you had to live with these people all your live, random rape wouldn't fly if you didn't want to get your head smashed in in most tribes.
