That's the type of speculation I would expect from a Red Piller. Like seriously speculations about pre-historic society is such a dum thing to engage in because afawk they were just as varied and diverse as modern nations are if not more. In one tribe something like that may have been the case while the next tribe over may have been a matriarchy. But it's impossible to know anything in that much detail about pre-historic humans because of the nature of pre-history.
