In his article "Comparing Timeline Rhythms in Pygmy and Bushmen Music," Adrian Poole uses computational phylogenetic analysis to assess the similarity between canonical rhythmic patterns from two African musical cultures. He then uses these analyses to evaluate previous claims of a common origin for their (now) distinct musical practices. Poole was unable to find clear evidence of a common origin, and here I provide additional analyses of these timelines casting further doubt on such claims. Instead, I offer a perspective from convergent evolution/sociobiology which can account for the broad similarities that exist between these two sets of timelines. I conclude with a critique of the claim of Poole and others that African timelines and the musical cultures in which they appear are especially resistant to change.

类比，同源性和有节奏的系统学：评阿德里安·普尔的《《侏儒与布什曼》音乐中的时间轴节奏比较》

阿德里安·普尔（Adrian Poole）在他的文章“比较侏儒音乐人和布什曼音乐中的时间线节奏”中，运用计算系统发育分析来评估两种非洲音乐文化的规范节奏模式之间的相似性。然后，他使用这些分析来评估他们先前（现在）独特的音乐实践中具有共同起源的先前主张。普尔无法找到有共同起源的明确证据，在这里，我提供了对这些时间表的进一步分析，使人们对此类主张进一步产生怀疑。取而代之的是，我从融合进化/社会生物学的角度提供了一个观点，可以解释这两套时间轴之间存在的广泛相似性。最后，我对普尔（Poole）等人的主张进行了批评，认为非洲的时间线及其出现的音乐文化特别难以改变。
