亲属识别有助于许多动物的合作进化，但不确定微生物是否也能利用它来关注亲属的利他行为。在这里，我们展示了社会性变形虫——紫齿兽在一些个体死亡以帮助其他个体的情况下，更倾向于与自己的亲属组成群体。通过将利他主义指向亲属，D。一般来说，purpureum应该避免亲缘关系d所经历的嵌合的代价。discoideum。
Kin recognition helps cooperation to evolve in many animals, but it is uncertain whether microorganisms can also use it to focus altruistic behaviour on relatives. Here we show that the social amoebaDictyostelium purpureumprefers to form groups with its own kin in situations where some individuals die to assist others. By directing altruism towards kin,D. purpureumshould generally avoid the costs of chimaerism,experienced by the relatedD. discoideum.
