@gina@fosstodon.org When men discover the function of sperm, the transition from matriarchy to patriarchy occurs. This discovery occurs over time, because almost a year passes between the sexual act and the birth of children. So humans wonder whose child will that child be? To ensure paternity, men must subjugate women, thus making women the property of men, and patriarchy and the private ownership of women and children are born. Matriarchy disappears and patriarchy arises in its place.
