EEB 122 - Principles of Evolution, Ecology and Behavior
Lecture 36 - Selfishness and Altruism. Originally, altruism and self-sacrifice were thought to be incompatible with natural selection, even by Darwin. Now we have several explanations for how altruism can increase an individual's fitness. One is kin selection, or the idea that helping relatives can help increase one's genes in the population. Another involves ecological constraints and punishments. Here, individuals contribute to the group and wait their turn to reproduce. (from oyc.yale.edu)
