female chimps stick together, have their own inner social dynamic, and attack the male chimps as a group. whenever a rising male chimp challenges the dominant alpha chimp, the group of women will often help the present dominant chimp attack the challenger, exactly the same way that female humans join with whoever holds the power dynamic and attack as a mob any dissenter or challenger. the challenger can only win by: first proving himself. he must cause the alpha chimp to demonstrate fear or uncertainty when engaged in the challenge. even the slightest hesitancy or misstep will be detected by the women, who watch for it like hawks. the moment he shows hesitancy, it's pretty much over for him. secondly he must win acceptance of the females through grooming and interaction. only then will they stop helping the current alpha chimp attack him. once they have decided, within a very short time, they all switch sides and the former alpha chimp is neglected and abandoned, treated like he never did nothing for them. regime change has occurred. female humans are again exactly the same. they will rabidly defend the power structure, but as soon as it changes, they will side with the very people they attacked only last week and act as though they have always been their most ardent allies and believers. chimp social dynamics aren't set in stone however. there have been cases where two males will decide to share the power and forego bothering to please the group of females. this shows the earliest stages of an evolution which humans must have undertaken, when men decided on allotting women rather than deal with the constant violence of competing for them, creating marriage. it's probable beyond this point that the female mind never evolved, hence the astounding similarities between female humans and chimps (this is actually proven: y chromosome high divergence between humans and chimps https://www.nature.com/articles/nature08700 x chromosome low divergence: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4537231/ once men started to select breeding partners for women, women had not much evolutionary pressure to advance. to this day women still select for only dominant chimp-like qualities in men. humans have rapidly evolved to become extremely intelligent, yet there is no concordant female selection of this trait. it happened because men selected other men for their intelligence. females have never evolved any ability to select for intelligence, if anything they may have slightly evolved a repugnance to it because they recognise it as something that will control them and inhibit their ability to engage in the freedom of their own sexual selection.
