Patriarchal Bias in "Survival of the Friendliest" by Brian Hare and Vanessa Wood?

 The claim is made that female Bonobos are more violent toward male bonobos than female chimps are to male chimps due to female bonobos having larger amounts of Oxytocin (with the males seen as an outside group). But the overall violence of Bonobos is much less than the overall chimps since the chimps rely on male patriarchy fueled by an escalating dynamic of dopamine and cortisol (spiking at ejaculation).

I find this to be a glaring hole in their claim - yes their oxytocin argument is accurate but in the larger context of patriarchy they are ignoring the matrifocal focus of our original human culture! The original human culture reliance on N/om is based on the same secret of the female orgasm dynamic as the bonobo culture. In contrast the farming plow agriculture culture of modern humans is based on patriarchy much like the chimpanzee culture -but that human patriarchy plow culture is only from the last Holocene - starting in the last 10,000 years.
