Quizplus · Accepted Answer

Altruism is a behavior in which an individual helps another at a cost to itself. This appears to contradict the principles of natural selection, which suggests that individuals should act in their own self-interest to maximize their own survival and reproductive success. However, altruism can be explained by the concept of kin selection, in which an individual helps relatives who share some of its genes, thus increasing the likelihood that those genes will be passed on to future generations.
