Remember the early planet of the apes films with gorillas be in the warrior class and chimps as the more settled calm group. Then it's been found they are just the opposite . gorillas are happy to set round all day munching on leaves, while chimps form up hunting parties or gangs to evade or raid other chimp communities. Often eating some of thier conquests. Rather vicious little critters. Especially the male adults.
