The evolution of puritanical morality has not always served to strengthen cooperation, but to reinforce male dominance and exclude women.

Puritanical morality regulates a range of seemingly insignificant behaviors, including those involving human sexuality. A sizable portion of the latter particularly burdens women, who are held responsible for the moral conduct of men. In my paper, I show that these norms have not necessarily served to evolve cooperation, but to subjugate and eliminate women from public life.
