  1. Statistical universals reveal the structures and functions of human musicSavage, Patrick E. - Proceedings of the National Academy of Sciences, 2015 - 2 Hypotheses

    The authors develop CantoCore, an expansion of Lomax's Cantometrics scheme, in order to code for additional candidate musical universals. No musical feature occurs with absolute universality, but several features occur with statistically significant frequency after controlling for historical relatedness, and an additional set of features were found to be universally related to each other. The authors highlight the role of these features in human coordination and cohesion, as well as their their utility to the fields of musical cognition and evolution.

  2. The structure of cross-cultural musical diversityRzeszutek, Tom - Proc. R. Soc. B, 2012 - 1 Hypotheses

    By analyzing patterns of between- and within-population musical variability among 16 Austronesian-speaking aboriginal groups, the researchers hope to evaluate degree of similarity to structures of human genetic diversity. As in the genetic domain, within-population variance is found to be much higher than between-population variance, leading the researchers to suggest that patterns of musical distance and divergence may serve as an indicator of cultural evolution.

  3. Musical Diversity in India: A Preliminary Computational Study Using CantometricsDaikoku, Hideo - Keio SFC Journal, 2020 - 3 Hypotheses

    The authors examine musical diversity in India using cantometric data from 32 Indian societies with the goal of better understanding how music varies between and within cultures. They find very minor musical differences between language families, greater diversity between societies but within language families, and the most variation within societies.

  4. Correlations in the population structure of music, genes and languageBrown, Steven - Proc. R. Soc. B, 2014 - 6 Hypotheses

    By testing relationships between musical, geographic, genetic, and linguistic distance among nine indigenous groups in Taiwan, the researchers aim to quantitatively evaluate a developing theory of coevolution between these traits. An especially strong correlation between musical variability and genetic distance suggests that music may possess worldwide time depth, diversity, and universality equal to or greater than that of language, and could thus serve as a complementary marker for reconstruction of long-term population shifts.

  5. Complex societies precede moralizing gods throughout world historyWhitehouse, Harvey - Nature, 2019 - 3 Hypotheses

    Researchers tackle the moral gods hypothesis which proposes that moral gods enabled large-scale societies to evolve. They use 414 societies spanning 10,000 years in Seshat: Global History Databank and code 51 measures of social complexity and four measures of moral gods. The findings of the present study challenge the moral gods hypothesis. In the societies studied, complex societies appear to precede moral gods rather than the inverse of moral gods preceding complex societies.

  6. Quantitative historical analysis uncovers a single dimension of complexity that structures global variation in human social organizationTurchin, Peter - Proceedings of the National Academy of Sciences, 2017 - 1 Hypotheses

    Using the compiled database "Seshat: Global History Databank," researchers sampled 30 societies from 10 distinct regions of the world, testing 51 variables that were condensed into 9 "complex characteristic" variables. Researchers tested for correlates in how societies evolve structurally. Utilizing principal component analysis it was demonstrated that the complex characteristic variables were strongly associated, leading to theorization of structural and social evolution predictability.
