You mean Tsimane’ people? My hypothesis is that they don't have preference toward harmonic intervals, because they are not able to hear them. Similar to the fact that absolute pitch is more common in musicians. Just possessing necessary genes for perfect pitch is not enough. You also need to develop it at a young age, presumably through exposure to pitched sounds repetition.

The first paper you mention is this one: Universal and Non-universal Features of Musical Pitch Perception Revealed by Singing https://www.sciencedirect.com/science/article/pii/S096098221931036X https://www.sciencedirect.com/science/article/pii/S096098221... The hypothesis that Tsimane people "are not able to hear them" is refuted in this paper: Perceptual fusion of musical notes by native Amazonians suggests universal representations of musical intervals https://www.nature.com/articles/s41467-020-16448-6 https://www.nature.com/articles/s41467-020-16448-6

  > The hypothesis that Tsimane people "are not able to hear them" is refuted in this paper I have now read this paper and I cannot agree that it refutes this hypothesis. Testing for fusion/segregation concurrent sounds does not test, if a person is able to detect ratios of frequencies. One big issue with methodology of this study is that they assumed that liking/disliking an interval translates to consonance/dissonance. In some contexts (like horror film for example or certain music genres) I like dissonance more that consonance, since it better fits the theme. Liking something is influenced by a variety of factors. Another example: people generally like pretty things, but many people will dislike things, if they look too pretty. Culture can also influence what is likable. It's an interesting study, but IMO, more research is needed before we can reach any conclusions.
