虽然哺乳动物中很少有男性照顾父母，但许多灵长类动物中的成年男性会照顾婴儿和青少年。这种护理通常是以梳理、携带、在竞争互动中支持以及防止杀害婴儿的形式进行的(2，3)。为了将这些行为解释为真正的父母照顾，雄性必须有选择地直接照顾自己的后代，这种照顾必须产生健康益处(4)。除了雄性保护可能的后代免受杀婴(5)外，生活在多雄、多雌性社会群体中的雄性灵长类动物没有显示出有选择地直接照顾自己的后代(6，7)。我们确定了野生热带大草原狒狒(Papio Cynocephalus)种群中75只幼崽的父亲身份，并收集了成年雄性代表幼崽干预争执纠纷的数据，作为一种雄性照顾形式。在这里，我们展示了成年雄性将他们的后代与无关的青少年区分开来，并在争斗中有选择地支持他们的后代。由于争斗中的支持可能有助于获得等级，并保护青少年免受伤害和压力(2，3，5)，这可以被认为是真正的父母关怀。
Although male parental care is rare among mammals 1, adult males of many cercopithecine primate species provide care for infants and juveniles. This care is often in the form of grooming, carrying, support in agonistic interactions, and protection against infanticide(2,3). For these behaviours to be interpreted as true parental care, males must selectively direct care towards their own offspring and this care must result in fitness benefits(4). With the exception of males defending probable offspring from infanticide(5), male primates living in multi-male, multi-female social groups have not been shown to selectively direct care towards their own offspring(6,7). We determined paternity for 75 juveniles in a population of wild savannah baboons (Papio cynocephalus) and collected data on interventions in agonistic disputes by adult males on behalf of juveniles as a form of male care. Here we show that adult males differentiate their offspring from unrelated juveniles and selectively support their offspring in agonistic disputes. As support in agonistic disputes is likely to contribute to rank acquisition and protect juveniles from injury and stress(2,3,5), this can be considered true parental care.
