Steve Kaiser, here's an article to get you started on interfacing with reality.
"A study has shown that in contemporary hunter-gatherer tribes, men and women tend to have equal influence on where their group lives and who they live with. The findings challenge the idea that sexual equality is a recent invention, suggesting that it has been the norm for humans for most of our evolutionary history.
Mark Dyble, an anthropologist who led the study at University College London, said: “There is still this wider perception that hunter-gatherers are more macho or male-dominated. We’d argue it was only with the emergence of agriculture, when people could start to accumulate resources, that inequality emerged.”
Also, don't generalize the Yanomami to other Amazonian tribes. They aren't even true foragers and have spent hundreds of years being brutally treated by Europeans.
