对马立克种灵长类动物的实地研究表明，一些物种可能表现出一种共同的繁殖系统，其中两个或两个以上的雄性与一个雌性交配，并合作参与养育婴儿。然而，在实验室和实地条件下，都观察到雄性之间的高水平攻击。在鸟类的集体繁殖模式中，合作的雄性往往是密切相关的。在实验室测试的一个假设的改善侵略的基础上的亲属关系，四对交配的saguinus oedipus和Callithrix jacchus介绍了两个新的男性同种和自己的男性兄弟姐妹，从他们已经分开了至少4个月。两个物种对雄性同种的反应总体上存在显著差异（P<0.01）：S。与绒猴相比，俄狄浦斯雄猴对入侵者的反应明显更频繁。jacchusmales更频繁的气味标记比绢毛猴。在亲属男性的存在下，这些行为的频率显着降低，比在新的男性的存在下观察到的证据被认为是对亲属男性的偏好。有人认为，在野外条件下，雄性马蹄莲之间的合作可能是由亲属关系。此外，双胞胎，妊娠期短，以及在马立克种灵长类中看到的出生间隔都有助于个体动物可能合作的社会熟悉亲属的数量。
Field studies on callitrichid primates have suggested that some species may exhibit a communal breeding system in which two or more males mate with a single female and cooperatively participate in infant rearing. However, high levels of aggression have been observed between males under both laboratory and field conditions. In avian models for communal breeding, cooperating males are often closely related. In a laboratory test of a hypothesis of the amelioration of aggression based on kinship, four mated pairs of bothSaguinus oedipusandCallithrix jacchuswere introduced to both novel male conspecifics and to their own male siblings, from whom they had been separated for a minimum of 4 months. Significant differences (P< .01) were seen in the responses of the two species to male conspecifics generally:S. oedipusmales responded to intruders with overt aggression significantly more frequently than did marmosets whileC. jacchusmales more frequently scent‐marked than did tamarins. Evidence of preference for kin males was seen in the significantly decreased frequencies of these behaviors in the presence of kin males over those observed in the presence of novel males. It is argued that, under field conditions, cooperation between male callitrichids may be facilitated by kinship. Further, twin births, short gestation lengths, and interbirth intervals seen in callitrichid primates all contribute to the number of socially familiar kin with which an individual animal might cooperate.
