波利尼西亚在横跨地球三分之一的大洋的一系列非凡航行中定居，但定居的岛屿顺序仍然未知，它们的时间也存在争议。目前，不同的考古调查提出的日期有好几个世纪之隔。在这里，使用来自21个关键太平洋岛屿种群的仅430个当代个体的全基因组数据和新颖的特定祖先的计算分析，我们揭开了这个巨大的、分散的岛屿网络的详细遗传史。我们对波利尼西亚分支迁徙序列的重建揭示了一系列创始人的扩张，其特点是变异的方向性丧失，这些变异最初起源于萨摩亚，首先传播到库克群岛(拉罗通加)，然后传播到社会(Tōtaiete mā)群岛(11世纪)，西澳大利亚(Tuha‘a Pae)群岛和TuāMotu群岛(12世纪)，最后到北部的Marquas(Te Henua’ENANA)群岛，以及南部的Raivavae和复活节岛(Rapa Nui)，这是波利尼西亚最东端的岛屿，大约在公元1200年经由Mangareva定居。
Polynesia was settled in a series of extraordinary voyages across an ocean spanning one third of the planet, but the sequences of islands settled remain unknown and their timings disputed. Currently, several centuries separate the dates suggested by different archaeological surveys. Here, using genome-wide data from merely 430 contemporary individuals from 21 key Pacific island populations and novel ancestry-specific computational analyses, we unravel the detailed genetic history of this vast, dispersed island network. Our reconstruction of the branching Polynesian migration sequence reveals a serial founder expansion, characterized by directional loss of variants, that originated in Samoa and spread first through the Cook Islands (Rarotonga), then to the Society (Tōtaiete mā) Islands (11th century), the western Austral (Tuha’a Pae) Islands and Tuāmotu Archipelago (12th century), and finally to the widely separated, but genetically connected, megalithic statue-building cultures of the Marquesas (Te Henua ‘Enana) Islands in the north, Raivavae in the south, and Easter Island (Rapa Nui), the easternmost of the Polynesian islands, settled in approximately 1200 CE via Mangareva.
