Question

Quizplus · Accepted Answer

Altruistic behaviors can arise through natural selection if the actions of the altruist increase the likelihood that some of its genes will be passed on to the next generation. This can happen if the altruist helps relatives who share the same genes or if the altruistic behavior increases the altruist's reputation and status within the group, which can lead to increased opportunities to breed.
