I have the same theory on women having been selected for caring about their environment.

I see that as an argument for choosing traditional gender roles because it seems to me that one of the main causes of conflict in 50/50 relationships are these arguments about chores, tidiness, etc.

Splitting chores 50/50 seems like asking for trouble given that men and women have evolved differently in this regard - he ends up feeling that she's endlessly nagging him, she ends up feeling that she has to manage him like a child.

Seems like the traditional breadwinner/homemaker setup would be a solution to this problem.
