Abstract

The appearance of people associated with the Lapita culture in the South Pacific around 3,000 years ago marked the beginning of the last major human dispersal to unpopulated lands. However, the relationship of these pioneers to the long-established Papuan people of the New Guinea region is unclear. Here we present genome-wide ancient DNA data from three individuals from Vanuatu (about 3,100–2,700 years before present) and one from Tonga (about 2,700–2,300 years before present), and analyse them with data from 778 present-day East Asians and Oceanians. Today, indigenous people of the South Pacific harbour a mixture of ancestry from Papuans and a population of East Asian origin that no longer exists in unmixed form, but is a match to the ancient individuals. Most analyses have interpreted the minimum of twenty-five per cent Papuan ancestry in the region today as evidence that the first humans to reach Remote Oceania, including Polynesia, were derived from population mixtures near New Guinea, before their further expansion into Remote Oceania. However, our finding that the ancient individuals had little to no Papuan ancestry implies that later human population movements spread Papuan ancestry through the South Pacific after the first peopling of the islands.

  • Ancient DNA studies of Polynesia have sequenced only four samples from one western Polynesian island and three near-modern samples from one eastern Polynesian island, with low genotype density and limited overlap.

    “Meanwhile, ancient DNA studies have sequenced only four samples from one island in western Polynesia and three near-modern samples from one island in eastern Polynesia, all with low genotype density, still lower between-sample genotype overlap, and different time frames17,18.”

    From Paths and timings of the peopling of Polynesia inferred from genomic networks (2021) · cites this paper as [17]

    The paper’s ancient-DNA passage (section labeled Abstract; page unavailable) explicitly places its four sequenced individuals on two islands: three on Efate, Vanuatu, and one on Tongatapu, Tonga—not four on one western Polynesian island. It reports 139,461–231,944 covered SNPs per individual, but does not report three near-modern eastern Polynesian samples or the claimed between-sample genotype overlap. (LLM, conf=0.88)

  • Polynesians are predominantly descended from Austronesian-speaking voyagers.

    “The Polynesians are predominantly descended from Austronesian-speaking voyagers17”

    From Paths and timings of the peopling of Polynesia inferred from genomic networks (2021) · cites this paper as [17]

    The paper’s ancestry-model passage (labelled Abstract in our copy; no page given) identifies a population related to the First Remote Oceanians as the primary component in present-day Polynesians, and describes seafaring settlement of Remote Oceania. It does not establish that those ancestral voyagers spoke Austronesian languages; the Extended Data table labels some present-day sampled populations Austronesian-speaking, but not the ancient voyagers. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Admixture between Papuan and Austronesian source populations occurred on Vanuatu and other Melanesian islands in the thousand years before Polynesian settlement and was carried into Polynesia during settlement.

    “(Admixture between populations stemming from these two sources occurred on Vanuatu and other Melanesian islands in the thousand years before the settlement of Polynesia and was carried into Polynesia during its settlement17,79.)”

    From Paths and timings of the peopling of Polynesia inferred from genomic networks (2021) · cites this paper as [17]

    The paper’s Abstract (page unavailable) dates Papuan–First Remote Oceanian mixture to roughly 1,500–2,300 years before present and finds Papuan ancestry in present-day Polynesians. It does not locate that mixture on Vanuatu or other Melanesian islands, or establish that an already admixed population carried it into Polynesia during settlement. Instead, the ancient Vanuatu and Tongan individuals had little or no Papuan ancestry, and the paper infers later movements into Remote Oceania. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
