Trivers (1971) proposed the theory of direct reciprocity, which suggests that altruistic behavior can evolve if the benefits to the recipient, discounted by the probability of future reciprocation, exceed the costs to the altruist. This theory emphasizes the role of reciprocal interactions in the development of cooperative behaviors.
