Payment for labour in monkeys

摘要: Capuchins will voluntarily share treats with other monkeys that helped to secure them. Cooperative hunting, in which several individuals pursue prey but only one makes a capture, is central theories of human social and moral evolution1,2,3. But among primates, it known from the chimpanzee large-brained neotropical monkey, capuchin4,5,6,7. It probably evolved through either mutualism, two or more cooperators benefit simultaneously, reciprocal altruism, favour repaid by another8,9. We have found brown capuchins (Cebus apella) rewards obtained joint effort readily than individually. Even if hunting field involves selfish opportunism, this food incentive greatly enhance persistence cooperation.
