人们普遍认为，在齿鲸中，被称为“哨声”的高频音调声音是与“社交性”相关的，因为在海豚科动物中，它们是在社交背景下使用的。最近，哨声被假设为社会海豚的进化创新（“海豚假说”）。然而，“口哨”和“社会性”都是广泛的概念，每一个都代表了一个人物的集合。许多非海豚科动物，无论是独居还是群居，都能发出与海豚科动物哨声相同的声音。此外，字符相关性的假设是最好的测试系统发育的背景下，迄今尚未完成。在这里，我们总结了300多项关于鲸类音调声音和社会结构的研究数据，并对现有的关于它们共同进化的假设进行了遗传学测试。口哨声是齿鲸发出的“复杂”音调的声音，与社会性海豚相比，它标志着一个更具包容性的分支。一些生活在简单社会中的河流物种也使用口哨，并且在社会性的海豚科动物中已经失去了两次，所有的观察结果都与海豚假说不一致。然而，鲸类的音调声音和社会性是交织在一起的：（1）增加音调声音调制显着相关的群体规模和社会结构;（2）音调声音复杂性的变化显着集中在社会分支。此外，持续时间和最小频率相关，因为组大小和平均最小频率。研究广义概念的进化相关性，而不是它们的组成特征的进化相关性，充满了困难，而可用数据的限制限制了在这种情况下可以分析组成特征相关性的细节。我们的研究结果支持了社会性影响音调声音复杂性演变的假设。社会和口哨的复杂程度是相关的，这表明复杂的音调声音在社会沟通中发挥着重要作用。最低频率是较高的物种与大集团，并与持续时间呈负相关，这可能反映了增加的距离，非社会物种沟通。我们的研究结果在一系列替代性遗传学中基本稳定。我们的研究指出了关键物种，未来的研究对于丰富我们对声学通信和社会性相互作用的理解特别有价值。
It is widely held that in toothed whales, high frequency tonal sounds called 'whistles' evolved in association with 'sociality' because in delphinids they are used in a social context. Recently, whistles were hypothesized to be an evolutionary innovation of social dolphins (the 'dolphin hypothesis'). However, both 'whistles' and 'sociality' are broad concepts each representing a conglomerate of characters. Many non-delphinids, whether solitary or social, produce tonal sounds that share most of the acoustic characteristics of delphinid whistles. Furthermore, hypotheses of character correlation are best tested in a phylogenetic context, which has hitherto not been done. Here we summarize data from over 300 studies on cetacean tonal sounds and social structure and phylogenetically test existing hypotheses on their co-evolution. Whistles are 'complex' tonal sounds of toothed whales that demark a more inclusive clade than the social dolphins. Whistles are also used by some riverine species that live in simple societies, and have been lost twice within the social delphinoids, all observations that are inconsistent with the dolphin hypothesis as stated. However, cetacean tonal sounds and sociality are intertwined: (1) increased tonal sound modulation significantly correlates with group size and social structure; (2) changes in tonal sound complexity are significantly concentrated on social branches. Also, duration and minimum frequency correlate as do group size and mean minimum frequency. Studying the evolutionary correlation of broad concepts, rather than that of their component characters, is fraught with difficulty, while limits of available data restrict the detail in which component character correlations can be analyzed in this case. Our results support the hypothesis that sociality influences the evolution of tonal sound complexity. The level of social and whistle complexity are correlated, suggesting that complex tonal sounds play an important role in social communication. Minimum frequency is higher in species with large groups, and correlates negatively with duration, which may reflect the increased distances over which non-social species communicate. Our findings are generally stable across a range of alternative phylogenies. Our study points to key species where future studies would be particularly valuable for enriching our understanding of the interplay of acoustic communication and sociality.
