The chimps are shockingly sophisticated. They've got "move swiftly, strike vigorously and secure the fruits of victory" down pat.
I'd love to know more about how their raiding parties are organized. How does the party decide whether to attack of withdraw? Do all adult males in a colony (is that the right word?) participate in raiding? Do those who do participate gain any benefits from it personally such as mating rights or extra food or prestige? Who decides when it's time to go out on patrol?
