Final answer:
In a social organization, selection favors individuals who perform altruistic behaviors to increase their personal reproductive success.
Step-by-step explanation:
In a social organization consisting of cooperative individuals, selection will always favor individuals that increase their personal reproductive success by performing altruistic behaviors.
Altruistic behaviors are actions that lower the fitness of the individual but increase the fitness of another individual. Examples of altruistic behaviors can be seen in various social animals, such as worker bees maintaining the queen bee, meerkats keeping sentry, and wolves sharing their prey with pack members.
Performing altruistic behaviors allows individuals to enhance their overall fitness by helping close relatives and increasing the chances of passing on their own genes through kin selection.
