编制了138种灵长类动物的婴儿皮毛染色资料。测试了灵长类动物产衣的三种功能假说--异地保护、婴儿防御和亲子关系斗篷。在所检查的物种中，超过一半的新生儿毛皮与成人毛皮形成了对比。微妙或不明显的对比比夸张的对比更常见。平均产后5.7周，胎衣开始变化，至18.0周，胎衣消失。在大多数物种中，第一个失去出生颜色的身体部位是头部和/或背部。功能分析没有为唯一发表的假说--异种假说提供支持，而为两个新假说--婴儿防御和亲子关系斗篷提供了部分支持。睾丸重量和出生毛皮反差之间的显著关联支持了交配系统和婴儿反差之间的联系。这是从避免杀害婴儿的角度来讨论的。新生儿的皮毛被建议被明确地区分为不显眼和炫耀的类型，而不是通过连续的层次来区分，例如颜色。亚种分化和共同祖先的模式被评估。
Pelage coloration of infants was compiled for 138 species of primates. Three functional hypotheses--alloparental, infant defense, and paternity cloak--for primate natal coats are tested. Neonatal pelage contrasted with adult pelage in over half of the species examined. Subtle or inconspicuous contrast was more common than flamboyant contrast. Natal coats began to change at 5.7 weeks and disappeared by 18.0 weeks postpartum on average. The first body part to lose natal coloration was the head and/or dorsum in the majority of species. Functional analyses provided no support for the only published hypothesis--alloparental--while providing partial support for two new hypotheses--infant defense and paternity cloak. A significant association between testes weight and natal coat contrast supports a link between mating system and infant contrast. This is discussed in terms of infanticide avoidance. Natal coats are proposed to be categorically differentiated into inconspicuous and flamboyant types, not differentiated by a continuous gradation, such as color. Subspecific differentiation and patterns of shared ancestry are assessed.
