Excellent book. Heres a short summary:
Bradley makes what at the time is an extraordinary claim: europeans are closely related to neanderthals, moreso than any other race. About 25 years later, through DNA testing, Bradley is absolved. He then uses this claim to argue the evolutionary journey for these neanderthals-turned-homosapiens was hindered by the freezing glacial temperatures of ancient europe in a way that other races didnt experience. One evolutionary hinderance he says is increased sexual dimorphism, between white men and women, leading those men and women to view each other as separate species. He uses this as a major reason for white patriarchy. Sex was less frequent and more based on a need than the natural human desire to satiate lust combined with its biological function, nor could they appreciate of the beauty of sex and the body. Women and men alike covered themselves from the cold, covering their sex! The sex and sexuality of the white woman became shrouded in mystery, pushing european women to be ashamed of their sex, to appear mostly asexual except when called to do otherwise by white men.
Increased levels of aggression is another biological (mal)adaptation coming from heightened competition between men in glacial temperatures fighting for scarce resources, becoming woven into cultural attitudes for conquest and dominance.
Theres more but im tired of typing lol, read this book!
