Bonobos are just as close and they're matriarchal. They're a very different species.

They're chimps that are on the other side of the Congo river (and both types of genus Pan can't swim).

They're super close to chimps (and definitely much closer than us), rather than "a very different species".

Yes, and that’s a good point too. Pretty big difference between the sexes with them as well.
