The average Homo sapiens father has always been older than the average Homo sapiens mother, the study found, with men becoming parents at 30.7 years old, versus 23.2 years for women.
It’s interesting that this trend extends even past the agricultural evolution, back during the “communistic” hunter-gatherer societies.
Older men had the resources to dominate culture in ways younger men did not. Math checks out. Theoretically most societies also had younger men being named to older men as well around this time so they were too busy kissing boys. That last part the boy kissing I think is a way bigger factor in thr amth that is undressed here.
Interestingly older men seem to be more mature and make better fathers than young men so there could be a selection bias at play as well.
