在鸟类和哺乳动物中，社会性鸣叫的学习比鸣叫学习更常见。与鸣叫学习不同，鸣叫学习不能很好地用性选择来解释。我们研究了鸣叫学习的起源和维持的假设。习得的鸣叫为声音学习的进化和机制提供了新的见解。习得的鸣叫是动物交流的最佳研究模型之一。在鸣禽中，学会鸣叫是最普遍的，它主要用于性内选择和配偶吸引。学习不同种类的声音信号，被称为接触呼叫，在各种各样的物种中被发现，它们被用来调解个体之间的社会互动。我们认为，呼叫学习提供了一个分类丰富的系统，研究可检验的假说的进化起源的声乐学习。我们描述和批判性地评估了四个不相互排斥的假说的起源和当前功能的声音学习的呼叫，这提出了呼叫学习（1）提高听觉检测和识别，（2）信号本地知识，（3）信号组成员，或（4）允许编码更复杂的社会信息。我们提出了测试这四个假设的方法，但强调所有这些都有一个共同的想法，即社会生活，而不是性选择，是声乐学习的核心驱动力。最后，我们确定了未来的研究领域的呼叫学习，可以提供动物和人类的发声学习的起源和机制的新观点。
HighlightsLearning of social calls is more common among birds and mammals than song learning.Unlike song learning, call learning is not well explained by sexual selection.We examine hypotheses for the origin and maintenance of call learning.Learned calls give new insight into the evolution and mechanisms of vocal learning.Learned song is among the best-studied models of animal communication. In oscine songbirds, where learned song is most prevalent, it is used primarily for intrasexual selection and mate attraction. Learning of a different class of vocal signals, known as contact calls, is found in a diverse array of species, where they are used to mediate social interactions among individuals. We argue that call learning provides a taxonomically rich system for studying testable hypotheses for the evolutionary origins of vocal learning. We describe and critically evaluate four nonmutually exclusive hypotheses for the origin and current function of vocal learning of calls, which propose that call learning (1) improves auditory detection and recognition,(2) signals local knowledge,(3) signals group membership, or (4) allows for the encoding of more complex social information. We propose approaches to testing these four hypotheses but emphasize that all of them share the idea that social living, not sexual selection, is a central driver of vocal learning. Finally, we identify future areas for research on call learning that could provide new perspectives on the origins and mechanisms of vocal learning in both animals and humans.
