I would be interested to learn of these exceptions - I don't know of them.

> Human's have had (and continue to have) many forms of social living..

No doubt. That societies outside our Western history have non-patriarchal societies seems like a good signposting to me. But who would deny that our history is a tale of male domination and present state is one of continuing lopsidedness. The only female figures who stand out in history are almost always presented as whores either to emotion or men (e.g. Mary Magdalena, Cleopatra).

Let me say that I think mongamy, and not polygamy, is a central feature of male-dominated societies. As monogamy ensures (to some extent) that patrilinear genetics can be followed.
