Question

Quizplus · Accepted Answer

Kin selection predicts that altruistic behavior is more likely among relatives because aiding a relative can increase the likelihood of passing on shared genes, resulting in greater fitness for the altruistic individual in the long run. This applies to a variety of animals, not just higher animals, and the percentage of altruistic individuals in a related group can vary depending on the specific situation and degree of relatedness. Group selection is not necessarily more likely in families.
