 If evolution is true, cultural evolution is true, why is it that all of human history, we have these patriarchal systems, all of these cultures that are independently developing, they all came up with the same model of patriarchy. How do you explain that from an evolutionary perspective? How could something so dysfunctional and evil end up dominating the entire human history? Because they started out as hunter gatherer societies where you had the men playing the role of the hunters and the warriors because of a slight advantage in physical strength, whereas the women were connected to the children, the upbringing, the home. The roles were discerned that way and they don't have to stay that way. We adapt and improve.
