The domestication syndrome refers to a set of traits that are the by-products of artificial selection for increased tolerance toward humans [1-3]. One hypothesis is that some species, like humans and bonobos, "self-domesticated" and have been under selection for that same suite of domesticated phenotypes [4-8]. However, the evidence for this has been largely circumstantial. Here, we provide evidence that, in marmoset monkeys, the size of a domestication phenotype-a white facial fur patch-is linked to their degree of affiliative vocal responding. During development, the amount of parental vocal feedback experienced influences the rate of growth of this facial white patch, and this suggests a mechanistic link between the two phenotypes, possibly via neural crest cells. Our study provides evidence for links between vocal behavior and the development of morphological phenotypes associated with domestication in a nonhuman primate.
驯化综合征是指一组特征，这些特征是对人类的耐受性增强的人工选择的副产品[1-3]。一种假说认为，某些物种，如人类和倭黑猩猩，“自我驯化”，并一直受到同一套驯化表型的选择[4-8]。然而，这方面的证据在很大程度上只是间接的。在这里，我们提供的证据表明，在狨猴中，驯化表型的大小——面部白色皮毛斑块——与它们的亲和性发声反应程度有关。在发育过程中，父母发声反馈的数量影响着面部白色斑块的生长速度，这表明这两种表型之间存在一种机制联系，可能是通过神经嵴细胞。我们的研究为非人类灵长类动物中与驯化相关的发声行为和形态表型发育之间的联系提供了证据。
