Question

Quizplus · Accepted Answer

The example of friends sacrificing themselves to save a drowning friend does not support kin selection because the individuals involved are not genetically related. Kin selection involves altruistic behavior toward genetically related individuals, in which the altruistic behavior benefits the genetic fitness of the altruistic individual's kin. In this example, the friends who sacrificed themselves were not related to the drowning friend, so their behavior cannot be explained by kin selection.
