Altruism can evolve among animals based on how closely related they are. In real life, signs like scent that show relatedness change over time along with the strategies animals use. By using computer models and math, researchers showed how altruism can develop and last when relatedness varies in different social groups. This means that in nature, animals can show altruistic behaviors even when they are not directly related, and these behaviors can be strong, not just weak.
