论文摘要
文化系统发育或文化的“树木”通常是使用生物学的方法来建立的，这些方法使用伪影中的相似性和差异来推断产生它们的人群之间的历史关系。尽管这些方法已经产生了重要的见解，尤其是在语言学中，但研究人员继续讨论文化系统发育因水平传播高水平而导致的文化系统发育程度。在这项研究中，我们提出了一种使用动态社区检测的系统发育重建的新方法，该方法明确说明了谱系之间的传播。我们使用了来自电子音乐艺术家之间1,498,483个协作关系的数据，以基于观察到的种群结构来构建一种文化系统发育。结果表明，尽管系统发育在根本上是树状的，但水平传播是常见的，种群永远不会完全隔离。此外，我们发现了证据表明，在1975年至1999年之间，电子音乐多样性有所增加。本研究中使用的方法可作为新的R包装，称为Dyncommphylo。未来的研究应将这种方法应用于其他文化系统，例如学术出版和电影，以及可获得高分辨率生殖数据的生物系统，以评估跨域的演化水平如何变化。
Cultural phylogenies, or "trees" of culture, are typically built using methods from biology that use similarities and differences in artifacts to infer the historical relationships between the populations that produced them. While these methods have yielded important insights, particularly in linguistics, researchers continue to debate the extent to which cultural phylogenies are tree-like or reticulated due to high levels of horizontal transmission. In this study, we propose a novel method for phylogenetic reconstruction using dynamic community detection that explicitly accounts for transmission between lineages. We used data from 1,498,483 collaborative relationships between electronic music artists to construct a cultural phylogeny based on observed population structure. The results suggest that, although the phylogeny is fundamentally tree-like, horizontal transmission is common and populations never become fully isolated from one another. In addition, we found evidence that electronic music diversity has increased between 1975 and 1999. The method used in this study is available as a new R package called DynCommPhylo. Future studies should apply this method to other cultural systems such as academic publishing and film, as well as biological systems where high resolution reproductive data is available, to assess how levels of reticulation in evolution vary across domains.
