Monkey cooperation and fairness
A pair of capuchin monkeys (Cebus apella) show very compelling signs of cooperation and a sense of fairness, by working together to solve a problem using tools, and then sharing the reward. They also seem to understand fairness: when unequal rewards are given to one monkey and not another, the monkey receiving the lesser treat would rather go hungry than accept anything less than an equal reward.
