关于波利尼西亚人起源的争论最近因遗传证据重新活跃起来，这些证据表明在公元前2000年从新几内亚地区向西波利尼西亚进行了二次迁徙。利用来自东波利尼西亚古代文化中心——背风社会群岛（Leeward Society Islands）的全基因组常染色体数据，我们发现，居民的基因组也显示出这种混合的证据，可以追溯到1700 - 1200年前。这支持东波利尼西亚较晚的定居年表，开始于波利尼西亚社会内部分化后约1000 BP。超过70%的背风社会岛民的常染色体祖先来自东南亚岛屿，其中菲律宾的低地人口是最大的单一潜在来源。在公元前2000年的第二次迁徙之前，这些进入波利尼西亚的长途移民经历了与北美拉尼西亚人的额外融合。此外，背风社会群岛的mtDNA和Y染色体谱系的遗传多样性与所罗门群岛中北部波利尼西亚异常点的东波利尼西亚定居的语言证据是一致的。这些结果强调了背风社会群岛复杂的人口历史，并挑战了基于东波利尼西亚从萨摩亚定居的文化进化的系统发育模型。
The debate concerning the origin of the Polynesian speaking peoples has been recently reinvigorated by genetic evidence for secondary migrations to western Polynesia from the New Guinea region during the 2nd millennium BP. Using genome-wide autosomal data from the Leeward Society Islands, the ancient cultural hub of eastern Polynesia, we find that the inhabitants’ genomes also demonstrate evidence of this episode of admixture, dating to 1,700–1,200 BP. This supports a late settlement chronology for eastern Polynesia, commencing ~1,000 BP, after the internal differentiation of Polynesian society. More than 70% of the autosomal ancestry of Leeward Society Islanders derives from Island Southeast Asia with the lowland populations of the Philippines as the single largest potential source. These long-distance migrants into Polynesia experienced additional admixture with northern Melanesians prior to the secondary migrations of the 2nd millennium BP. Moreover, the genetic diversity of mtDNA and Y chromosome lineages in the Leeward Society Islands is consistent with linguistic evidence for settlement of eastern Polynesia proceeding from the central northern Polynesian outliers in the Solomon Islands. These results stress the complex demographic history of the Leeward Society Islands and challenge phylogenetic models of cultural evolution predicated on eastern Polynesia being settled from Samoa.
