To explore Massim\ngenetic history, we generated genome-wide data from across the region and found variable\nlevels of Papuan-related (indigenous) ancestry, including a novel ancestry associated with\nRossel Island, and Austronesian-related ancestry that arrived later. We find genetic\nevidence for different patterns of contact across PNG, the Massim, and the Bismarck and\nSolomon Archipelagoes for Austronesian-related vs. Papuan-related ancestry, with more\ngeographic restriction for the latter. Moreover, Kula-practicing groups share more genetic\nsimilarity than do other groups, and this likely predates the origin of Kula, suggesting that\nhigh between-group contact facilitated the formation of Kula. Our study provides the first\ncomprehensive genome-wide assessment of Massim inhabitants and new insights into the\nfascinating Kula system.","dates":{"updated":"2022-07-27 15:30:00"},"accession":"EGAS00001006010","cross_references":{"TAXONOMY":["9606"],"EGA":["EGAD00001008545","EGAC00001002522"]}}
