AP BIOLOGY

Detailed explanation-1: -In evolutionary biology, reciprocal altruism is a behaviour whereby an organism acts in a manner that temporarily reduces its fitness while increasing another organism’s fitness, with the expectation that the other organism will act in a similar manner at a later time.

Detailed explanation-2: -Evolutionary biologists determined that an animal’s behaviors are altruistic when they benefit other individuals, even to the potential detriment of themselves. Species with complex social structures like bees, ants and termites provide great examples of biological altruism.

Detailed explanation-3: -Many acts of animal altruism can be explained via two established theories. Kin selection dictates that animals will preferentially help their relatives, thereby benefiting the altruist’s own genetic legacy. Kin selection can explain many acts of altruism among animals that live in groups.

Detailed explanation-4: -Altruistic Behaviors Behaviors that lower the fitness of the individual engaging in the behavior, but increase the fitness of another individual, are termed altruistic. Examples of such behaviors are seen widely across the animal kingdom.

Detailed explanation-5: -: unselfish regard for or devotion to the welfare of others.
