True. Most of the matriarchies were in Africa, and they were decimated completely when European colonizers showed up. There were a few matriarchies elsewhere, but not many. Most human societies were patriarchies. It would be interesting, from a purely scientific point of view, to see what the african matriarchies would have developed into? How does that sort of thing affect development? Etc.
