During the evolution of cooperation it may have become critical for individuals to compare their own efforts and pay-offs with those of others. Negative reactions may occur when expectations are violated. One theory proposes that aversion to inequity can explain human cooperation within the bounds of the rational choice model1, and may in fact be more inclusive than previous explanations 2, 3, 4, 5, 6, 7, 8. Although there exists substantial cultural variation in its particulars, this ‘sense of fairness’ is probably a human universal 9, 10 that has been shown to prevail in a wide variety of circumstances 11, 12, 13. However, we are not the only cooperative animals14, hence inequity aversion may not be uniquely human.

Many highly cooperative nonhuman species seem guided by a set of expectations about the outcome of cooperation and the division of resources15, 16. Here we demonstrate that a nonhuman primate, the brown capuchin monkey (Cebus apella), responds negatively to unequal reward distribution in exchanges with a human experimenter. Monkeys refused to participate if they witnessed a conspecific obtain a more attractive reward for equal effort, an effect amplified if the partner received such a reward without any effort at all. These reactions support an early evolutionary origin of inequity aversion.
