"Reevaluating Primate Power Dynamics: Females Assert More Influence Than Previously Thought"
A study challenges the assumption of male dominance in primate societies, finding that female-biased power structures or social equality between the sexes can be found within every major primate group. The research suggests that male-biased power is likely to develop in species where males have larger body sizes and longer canine teeth, while female power may emerge when the supply of available female mating partners is lower than male demand. The study also questions the assumption of ancestral male-biased power in primates, highlighting the presence of female-biased and equal power structures within many primate species.
