座头鲸的歌声是声音文化行为的一个非凡例子。在北方人口中，复杂的歌曲显示出缓慢演变的长期传统，而在南太平洋，当歌曲被邻近人口采用并迅速传播时，就会发生周期性革命。在这个物种中，声音学习不能在实验室中研究，而是从歌曲的复杂性和传播模式中推断出来。在这里，我们对整个南半球和北半球座头鲸种群进行了基于个体的文化进化模拟，以形式化这一推理过程。我们对歌曲突变过程和人群之间的接触模式进行了建模，并将我们的模型与在南太平洋人群中测量的歌曲主题共享模式进行了比较。低水平的突变加上罕见的种群相互作用足以紧密贴合南太平洋的多样性模式，包括从西向东革命的独特模式。有趣的是，引起南半球模拟革命的相同学习参数也引起了北半球人群文化进化的进化模式。我们的研究展示了如何使用文化进化方法来推断文化传播背后的学习过程以及它们如何产生紧急的人口水平过程。本文是主题“动物和人类的声音学习”的一部分。
Humpback whale song is an extraordinary example of vocal cultural behaviour. In northern populations, the complex songs show long-lasting traditions that slowly evolve, while in the South Pacific, periodic revolutions occur when songs are adopted from neighbouring populations and rapidly spread. In this species, vocal learning cannot be studied in the laboratory, learning is instead inferred from the songs' complexity and patterns of transmission. Here, we used individual-based cultural evolutionary simulations of the entire Southern and Northern Hemisphere humpback whale populations to formalize this process of inference. We modelled processes of song mutation and patterns of contact among populations and compared our model with patterns of song theme sharing measured in South Pacific populations. Low levels of mutation in combination with rare population interactions were sufficient to closely fit the pattern of diversity in the South Pacific, including the distinctive pattern of west-to-east revolutions. Interestingly, the same learning parameters that gave rise to revolutions in the Southern Hemisphere simulations gave rise to evolutionary patterns of cultural evolution in the Northern Hemisphere populations. Our study demonstrates how cultural evolutionary approaches can be used to make inferences about the learning processes underlying cultural transmission and how they might generate emergent population-level processes. This article is part of the theme issue ‘Vocal learning in animals and humans’.
