摘要: Although the Austronesian expansion had a major impact on languages of Island Southeast Asia, controversy still exists over genetic this expansion. The coexistence both Asian and Papuan ancestry in Eastern Indonesia provides unique opportunity to address issue. Here, we estimate recombination breakpoints admixed genomes based genome-wide SNP data date admixture between populations vs. Indonesia. Analyses two datasets indicate an eastward progression signal beginning about 4,000-3,000 y ago, which is excellent agreement with inferences languages. average rate spread genes was 0.9 km/y. Our results that strong as well linguistic they significantly advance our understanding biological origins human Asia-Pacific region.
