Matriarchy VS Patriarchy in primate species

Our 2 closest living relatives are Chimpanzees and Bonobos. Chimpanzees and Bonobos are also nearly identical to each other in their DNA. We only recently discovered that they were two distinct species.

Chimpanzee society is heavily patriarchal, whereas Bonobo society is heavily matriarchal.

Chimpanzee society has extremely high rates of murder, sexual assault, and infanticide.

Bonobo society has virtually none of that stuff. With crime rates even lower than the safest human societies. Even lower than egalitarian hunter gatherer tribes.

Just something to think about.
