灵长类动物沟通的手势和声音领域存在分歧和独立的研究传统，导致认知概念的定义和操作性的重大差异。然而，近年来，行为和神经生物学研究积累的证据表明，人类和非人类灵长类动物的沟通本质上是多模式的。因此，整合手势和语音交流的研究是及时的。在此，我们回顾证据表明，灵长类动物的手势和发声之间没有明显的区别，在何种程度上，他们显示的证据存在的关键语言属性：意向性，参考，象似性和话轮转换。我们还发现，在产生灵长类动物的手势和发声的神经生物学机制，以及在个体发育的灵活性高度重叠。这些发现证实了人类语言具有多模态起源。尽管如此，我们注意到，在类人猿中，手势似乎在近距离交流中扮演着携带（即主要是信息）的角色，而人类面对面的互动则相反。这表明一个进化的转变，携带的角色从手势到声音流，我们探讨这种过渡的携带方式。最后，我们建议未来的研究应关注复杂交际、社会性和合作倾向之间的联系，以加强语言起源的研究。
The presence of divergent and independent research traditions in the gestural and vocal domains of primate communication has resulted in major discrepancies in the definition and operationalization of cognitive concepts. However, in recent years, accumulating evidence from behavioural and neurobiological research has shown that both human and non-human primate communication is inherently multimodal. It is therefore timely to integrate the study of gestural and vocal communication. Herein, we review evidence demonstrating that there is no clear difference between primate gestures and vocalizations in the extent to which they show evidence for the presence of key language properties: intentionality, reference, iconicity and turn-taking. We also find high overlap in the neurobiological mechanisms producing primate gestures and vocalizations, as well as in ontogenetic flexibility. These findings confirm that human language had multimodal origins. Nonetheless, we note that in great apes, gestures seem to fulfil a carrying (i.e. predominantly informative) role in close-range communication, whereas the opposite holds for face-to-face interactions of humans. This suggests an evolutionary shift in the carrying role from the gestural to the vocal stream, and we explore this transition in the carrying modality. Finally, we suggest that future studies should focus on the links between complex communication, sociality and cooperative tendency to strengthen the study of language origins.
