There definitely could be an evolutionary reason why men biologically prefer adrenaline, technical subjects and showing off their muscles, whereas women prefer talking, being led and showing off their youth/beauty. After all, despite all the feminist/anti-sexist posturing in our society, no-one bats an eye when someone says that men are more aggressive. But even if there are first-order biological reasons ("encoded into the Y chromosome"), there could be second-order biological reasons. E.g. women choose when it comes to sex (the underlying biological reason being, men have more time and more chances (more sperm) to make kids, so they can afford to be less picky), so men will put more energy in displaying/becoming a good partner (e.g. by earning more money). I guess it's a similar logic to why murder is immoral - there's no immediate biological reason for it, but the groups where killing in-group members was condoned simply didn't survive.
