I notice that some anthropologist believe all humans were egalitarian in the past, and others believe inequality was more common they we currently we think with hunter gathers.
This seems to along with anthropologist using modern hunter gathers as way to look at the past which is now considered not a best practice from what I read. Which this influenced the egalitarian hunter gathers idea even more.
Not all hunter gatherers are egalitarian. The material conditions play a huge role. And there's evidence that for a couple thousand years after farming was developed, it was managed by egalitarian women's councils while nearby hunter gatherers became patriarchal in reaction to the dominance of women in farming society.
Yeah, there's some evidence that patriarchy was established by male dominated pastorialists/hunter primacy cultures extorting female dominated agri/gatherer dominant cultures by force.
That said everyone kind of has an axe to grind in anthropology so it's hard to tell how evidence should be weighted.
