Overview
Kin selection is a type of natural selection that occurs when individuals increase the reproductive success of their relatives. This can be explained by an individual’s willingness to act altruistically towards their kin, even if it means sacrificing their own reproductive success. This reproductive strategy is often seen in the animal kingdom, where animals assist their siblings in reproducing, or give up their own reproductive opportunities in order to take care of their relatives. Kin selection can also be seen in humans, where kin may act as a helpful support system in times of need, or contribute to the success of their relatives. It is ultimately a gene-centered approach to promoting socio-behavioral altruism, which helps to promote the survival and success of kin in the larger population.
