Kinship structures create persistent channels for language transmission pub prog_asa language, kinship, coevolution, cultural evolution, population genetics Languages are transmitted through channels created by kinship systems. Given sufficient time, these kinship channels can change the genetic and linguistic structure of populations. In traditional societies of eastern Indonesia, finely resolved cophylogenies of languages and genes reveal persistent movements between stable speech communities facilitated by kinship rules. When multiple languages are present in a region and postmarital residence rules encourage sustained directional movement between speech communities, then languages should be channeled along uniparental lines. We find strong evidence for this pattern in 982 individuals from 25 villages on two adjacent islands, where different kinship rules have been followed. Core groups of close relatives have stayed together for generations, while remaining in contact with, and marrying into, surrounding groups. Over time, these kinship systems shaped their gene and language phylogenies: Consistently following a postmarital residence rule turned social communities into speech communities. 2017-11 National Academy of Sciences 10.1073/pnas.1706416114 307 public Proceedings of the National Academy of Sciences 114 49 12910-12915 TRUE 1091-6490 FALSE no info:eu-repo/semantics/article
