Culture evolves in ways that are analogous to, but distinct from, genomes. Previous studies examined similarities between cultural variation and genetic variation (population history) at small scales within language families, but few studies have empirically investigated these parallels across language families using diverse cultural data. We report an analysis comparing culture and genomes from in and around northeast Asia spanning 11 language families. We extract and summarize the variation in language (grammar, phonology, lexicon), music (song structure, performance style), and genomes (genome-wide SNPs) and test for correlations. We find that grammatical structure correlates with population history (genetic history). Recent contact and shared descent fail to explain the signal, suggesting relationships that arose before the formation of current families. Our results suggest that grammar might be a cultural indicator of population history while also demonstrating differences among cultural and genetic relationships that highlight the complex nature of human history.

© 2019, The Author(s), under exclusive licence to Springer Nature Limited. The origins of religion and of complex societies represent evolutionary puzzles1–8. The ‘moralizing gods’ hypothesis offers a solution to both puzzles by proposing that belief in morally concerned supernatural agents culturally evolved to facilitate cooperation among strangers in large-scale societies9–13. Although previous research has suggested an association between the presence of moralizing gods and social complexity3,6,7,9–18, the relationship between the two is disputed9–13,19–24, and attempts to establish causality have been hampered by limitations in the availability of detailed global longitudinal data. To overcome these limitations, here we systematically coded records from 414 societies that span the past 10,000 years from 30 regions around the world, using 51 measures of social complexity and 4 measures of supernatural enforcement of morality. Our analyses not only confirm the association between moralizing gods and social complexity, but also reveal that moralizing gods follow—rather than precede—large increases in social complexity. Contrary to previous predictions9,12,16,18, powerful moralizing ‘big gods’ and prosocial supernatural punishment tend to appear only after the emergence of ‘megasocieties’ with populations of more than around one million people. Moralizing gods are not a prerequisite for the evolution of social complexity, but they may help to sustain and expand complex multi-ethnic empires after they have become established. By contrast, rituals that facilitate the standardization of religious traditions across large populations25,26 generally precede the appearance of moralizing gods. This suggests that ritual practices were more important than the particular content of religious belief to the initial rise of social complexity.

© 2019, The Author(s). The concept of cultural evolution was fundamental to the foundation of academic musicology and the subfield of comparative musicology, but largely disappeared from discussion after World War II despite a recent resurgence of interest in cultural evolution in other fields. I draw on recent advances in the scientific understanding of cultural evolution to clarify persistent misconceptions about the roles of genes and progress in musical evolution, and review literature relevant to musical evolution ranging from macroevolution of global song-style to microevolution of tune families. I also address criticisms regarding issues of musical agency, meaning, and reductionism, and highlight potential applications including music education and copyright. While cultural evolution will never explain all aspects of music, it offers a useful theoretical framework for understanding diversity and change in the world’s music.

Unfounded music copyright lawsuits inhibit musical creativity and waste millions of taxpayer dollars annually. Our aim was to develop and test simple quantitative methods in order to supplement traditional qualitative musicological analyses and improve the efficiency and transparency of music copyright lawsuits. We adapted automatic sequence alignment algorithms from computational biology to create a "percent melodic identity" (PMI) method that was initially developed to measure the cultural evolution of folk music from different cultures. This method automatically quantifies and visualizes the percentage of identical pitch classes shared between two melodic sequences. We applied the PMI method to a corpus of 20 pairs of melodies that had been the subject of legal decisions and that had previously been analyzed using automatic methods. We found that the PMI method was able to accurately predict 80% (16/20) of previous decisions, with PMIs below 50% usually resulting in decisions of no infringement (11/13 cases), and PMIs above 50% usually resulting in decisions of infringement (5/7 cases). Importantly, each of the four outlying cases could be explained by contextual factors not related to melodic similarity (e.g., lyrics, access). Our results provide promise for improving music copyright evaluation by supplementing traditional qualitative components with quantitative methods and visualization tools that are simple enough to be useful to juries, judges, and other non-musicologists.
