This article from The Guardian suggests a counter to the common concept that in the old days human societies were rigidly defined by gender roles.
Study shows that modern hunter-gatherer tribes operate on egalitarian basis, suggesting inequality was an aberration that came with the advent of agriculture
Our prehistoric forebears are often portrayed as spear-wielding savages, but the earliest human societies are likely to have been founded on enlightened egalitarian principles, according to scientists.
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.”
