While it is true that in some species (like chimpanzees, orangutans, and some baboons) males do seem to use aggression to coerce females to stay near them, or even to mate with them, there are also many other species (gibbons, many macaques, marmosets and tamarins, and Asian leaf monkeys) where males are not able to use aggression to coerce females at all. In fact in many species females can group together to form coalitions with which to resist male attempts at coercion or aggression.
