Evolution of Altruistic Behaviors
Two possible explanations for altruistic behavior
Kin selection: selection in favor of a gene because it benefits the animal’s relatives who are likely to carry the same gene. This would be
“nepotistic altruism”
Reciprocal altruism: the idea that animals help those who help them in return. Requires good
sensory organs and a well-developed brain to recognize those who did the favor.
