Youth/fertility, maternal empathy
vs
Status/resources, paternal dominance
Edit: I realised that was a bit short, but I can't be bothered to write a huge post about it so here's the TLDR:
We are primates
"Behavioral differentiation of male and female primates involves more than just mating behavior. Males are usually larger and physically dominant over females. Extreme sexual dimorphism is particularly characteristic of the semi-terrestrial monkeys and the great apes. The manner in which male and female children are socialized often differs. Following infancy, age-based play groups are usually the primary socializing group for males. These juvenile male cohorts often spend much of their time on the fringes of the troop territory in active physical play. For example, nearly half of the waking hours of young male gorillas are spent in rough play. This is comparable to the amount of time human children play if given the opportunity. For most non-human primates, play is critical for developing social bonds and social skills. Young female monkeys and apes are more often socialized in the safer areas of the community territory by their mothers and other older female relatives. Their play is usually less rough and focuses more on developing parenting skills and social ties among the females with whom they usually spend their lives. As adults, male primates are more likely to leave the community to join roaming bachelor groups and eventually join other communities."
