However, the relationship of these pioneers to the long established Papuans of the New Guinea region is unclear. We report genome-wide ancient DNA data from four individuals from Vanuatu (~3100-2700 years before present) and Tonga (~2700-2300 years before present), and co-analyze them with 778 present-day East Asians and Oceanians. Today, indigenous peoples of the South Pacific harbor a mixture of ancestry from Papuans and a population of East Asian origin that does not exist in unmixed form today, but is a match to the ancient individuals. Most analyses have interpreted the minimum of twenty-five percent 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, prior to the further expansion into Remote Oceania<sup><xref rid="R2" ref-type="bibr">2</xref>–<xref rid="R5" ref-type="bibr">5</xref></sup>. However, our finding that the ancient individuals had little to no Papuan ancestry implies later human population movements that spread Papuan ancestry through the South Pacific after the islands’ first peopling.</p></div></front><back><div1 type="bibliography"><listBibl><biblStruct><analytic><author><name sortKey="Sheppard, Pj" uniqKey="Sheppard P">PJ Sheppard</name></author><author><name

However, the relationship of these pioneers to the long established Papuans of the New Guinea region is unclear. We report genome-wide ancient DNA data from four individuals from Vanuatu (~3100-2700 years before present) and Tonga (~2700-2300 years before present), and co-analyze them with 778 present-day East Asians and Oceanians. Today, indigenous peoples of the South Pacific harbor a mixture of ancestry from Papuans and a population of East Asian origin that does not exist in unmixed form today, but is a match to the ancient individuals. Most analyses have interpreted the minimum of twenty-five percent 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, prior to the further expansion into Remote Oceania<sup><xref rid="R2" ref-type="bibr">2</xref>–<xref rid="R5" ref-type="bibr">5</xref></sup>. However, our finding that the ancient individuals had little to no Papuan ancestry implies later human population movements that spread Papuan ancestry through the South Pacific after the islands’ first peopling.</p></abstract></article-meta></front><body><p id="P2">Pacific islanders today derive from a mixture of two highly divergent ancestral populations<sup><xref rid="R3" ref-type="bibr">3</xref></sup>. One arrived in island southeast Asia more than 40,000 years before present (BP), and contributed to the ancestry of both indigenous Australians and Papuans, and hence to other Pacific islanders<sup><xref rid="R4" ref-type="bibr">4</xref></sup>. The second ancestral population is more closely related to mainland East Asians<sup><xref rid="R4" ref-type="bibr">4</xref></sup>, and is not found in unadmixed form today. The first humans to reach Remote Oceania—a term we use to refer to the region unoccupied prior to ~3,000 BP beyond the main Solomon Islands and in this case excluding Micronesia—were associated with the Lapita culture that spans 3,450-3,250 to 2,700-2,500 BP. These people spread into Remote Oceania using the first boats capable of long-distance sea travel, introduced new domesticated animals and plants, and their successors reached the most isolated islands of the eastern and southern Pacific by 1,000-700 BP<sup>6</sup>. Several hypotheses have been proposed to explain why present-day indigenous people of Near Oceania (New Guinea, the Bismarck Islands, and the Solomon Islands area) and Remote Oceania have ancestry both from Papuans and from populations of ultimate East Asian origin. In one set of models that has been favored by recent genetic studies<sup><xref rid="R3" ref-type="bibr">3</xref>–<xref rid="R5" ref-type="bibr">5</xref>,<xref rid="R7" ref-type="bibr">7</xref></sup>, the mixture occurred >3,000 BP during the expansion of populations of East Asian origin through the New Guinea region<sup><xref rid="R8" ref-type="bibr">8</xref></sup>. In the other set of models, the population of ultimate East Asian origin initially mixed little with Papuans<sup><xref rid="R9" ref-type="bibr">9</xref></sup> and it is later gene exchanges that account for the ubiquitous Papuan ancestry today<sup><xref rid="R2" ref-type="bibr">2</xref>,<xref rid="R10" ref-type="bibr">10</xref></sup>.</p><p id="P3">We obtained genome-wide ancient DNA data from three individuals from the Teouma site on Efate island, Vanuatu (<xref rid="SD1" ref-type="supplementary-material">Supplementary Information section 1</xref>), all directly radiocarbon dated to between 3110-2740 BP overlapping the Lapita period (<xref rid="T1" ref-type="table">Extended Data Table 1</xref>). We also obtained genome-wide ancient DNA data from an individual from the Talasiu site on Tongatapu island, Tonga, directly radiocarbon dated to 2680-2340, a period spanning the late Lapita and immediately post-Lapita period (<xref rid="SD1" ref-type="supplementary-material">Supplementary Information section 2</xref>; <xref rid="T1" ref-type="table">Extended Data Table 1</xref>). In dedicated clean rooms, we prepared powder from petrous bones<sup><xref rid="R11" ref-type="bibr">11</xref></sup>, extracted DNA<sup><xref rid="R12" ref-type="bibr">12</xref></sup>, and prepared up to four double-stranded libraries from each extract<sup><xref rid="R13" ref-type="bibr">13</xref></sup>. We enriched the libraries for 1.24 million targeted single nucleotide polymorphisms (SNPs)<sup><xref rid="R14" ref-type="bibr">14</xref></sup>, sequenced the products, and restricted to a single randomly drawn sequence for each SNP. This procedure resulted in 139,461–231,944 SNPs covered at least once in each of the individuals. The low ratio of sequences aligning to Y chromosome targets compared to targets on other chromosomes<sup><xref rid="R15" ref-type="bibr">15</xref></sup> reveals that all four individuals are females (<xref rid="T1" ref-type="table">Extended Data Table 1</xref>).

To test if the ancient individuals have any evidence of Papuan ancestry, we used <italic>qpWave/qpAdm</italic> to analyze allele frequency correlation statistics<sup><xref rid="R19" ref-type="bibr">19</xref></sup>. The ancient individuals and the Taiwanese Ami are consistent with descending from a common ancestral population to the exclusion of 14 worldwide outgroups (<italic>P</italic> ≫ 0.05 for the ancient individuals from both Vanuatu and Tonga). We estimate the possible range of Papuan ancestry in the Vanuatu individuals to be 0–11% and in the Tongan individual to be 0–17% (99% confidence intervals truncated at zero), significantly lower than the >25% Papuan ancestry in all present-day Oceanians (<xref rid="F2" ref-type="fig">Figure 2A</xref>). To test the hypothesis that the ancient Remote Oceanian individuals might be from the source population of the non-Papuan ancestry in Oceanians today, we computed the statistic <italic>f<sub>4</sub></italic>(Africa, <italic>Test</italic>; Australian, Polynesian), which evaluates the degree of allele sharing of a candidate <italic>Test</italic> population with Polynesians (at sites where Polynesians differ from Australians), and found that it is maximized when <italic>Test</italic>=Lapita_Vanuatu or <italic>Test</italic>=Lapita_Tonga (<xref rid="F5" ref-type="fig">Extended Data Figure 2B</xref>), as expected if Lapita were the true source. We conclude that the non-Papuan ancestry that is ubiquitous in Oceania is derived from a population related to the ancient individuals we analyzed, and that this ancestry reached uninhabited islands in Remote Oceania with little or possibly no mixture with Papuans. We call the population of which both the ancient Vanuatu and Tongan individuals were a part the ‘First Remote Oceanians’, and find that the ancestry fraction from this population is the single most important factor shaping genetic variation among Pacific islanders, accounting for most variation in measurements including genetic diversity (Pearson’s <italic>R</italic>=0.86, <italic>P</italic>=2×10<sup>−12</sup> for 42 non-Polynesian groups) (<xref rid="F5" ref-type="fig">Extended Data Figure 2</xref>) and proportion of archaic Denisovan ancestry (<italic>R</italic>=−0.96, <italic>P</italic> < 10<sup>−16</sup> for all 56 Oceanian groups) (<xref rid="F2" ref-type="fig">Figure 2</xref>).</p><p id="P6">Our evidence that early and geographically diverse Remote Oceanian individuals had little if any Papuan ancestry contradicts models that suggest significant Papuan contributions to Lapita people prior to their dispersal into Remote Oceania<sup><xref rid="R3" ref-type="bibr">3</xref>–<xref rid="R5" ref-type="bibr">5</xref></sup>. Instead, our results show that the Papuan genetic signature only appeared in many Remote Oceanian populations subsequent to initial settlement. To gain further insight into when the Papuan ancestry may have become ubiquitous in Remote Oceanians, we leveraged the fact that chromosome segments from ancestral populations break up at a known rate due to recombination, and that the inverse of the length of the segments translates to a date of mixture<sup><xref rid="R20" ref-type="bibr">20</xref></sup>. We estimate dates of ~50–80 generations ago using ALDER<sup><xref rid="R21" ref-type="bibr">21</xref>,</sup>, or 1,500–2,300 BP assuming 28.1 years (Methods) per generation<sup><xref rid="R22" ref-type="bibr">22</xref></sup> (<xref rid="F2" ref-type="fig">Figure 2D</xref>; <xref rid="F6" ref-type="fig">Extended Data Figure 3</xref>). We combined the statistical error of the genetic estimate and the uncertainty about the generation interval, and obtained a 95% confidence interval of 1239–1927 BP for a pool of Polynesians all of whom have similar Papuan ancestry proportions (<bold>Methods</bold>). This finding that Papuan-First Remote Oceanian mixture continued long after the Lapita period implies that the Polynesian ancestral population was not fully formed at that time, although we caution that alternative methods for dating Papuan mixture in Remote Oceanians arrived at older dates<sup><xref rid="R4" ref-type="bibr">4</xref>,<xref rid="R23" ref-type="bibr">23</xref>–<xref rid="R25" ref-type="bibr">25</xref></sup>. However, our ALDER dates are supported by direct ancient DNA evidence, as the Tongan individual at 2680-2340 BP carried little or no Papuan ancestry, providing unambiguous confirmation that the ancestral population of Polynesians was not fully formed by the end of the Lapita period.</p><p id="P7">We used <italic>qpGraph</italic> to explore models of population separation and mixture that might accommodate the ancient DNA data<sup><xref rid="R26" ref-type="bibr">26</xref></sup> (<xref rid="SD1" ref-type="supplementary-material">Supplementary Information section 3</xref>).

In <xref rid="F3" ref-type="fig">Figure 3</xref> we show the best fitting model, which suggests that the ancient individuals from Vanuatu and Tonga descend from an ancestral (presumably Lapita) population that separated earlier from the population that is the primary component in present-day Polynesians. This implies that not just Papuan ancestry but also deeply branching First Remote Oceanian ancestry was introduced to Remote Oceania through later movement of people. Thus, the minimum 25% Papuan ancestry seen in present-day Remote Oceanians is a conservative underestimate of the later population displacement. It is unlikely that there was 100% replacement, however, since we observe weak excess affinity of present-day Tongans to Lapita_Tonga in symmetry tests (<bold>Methods</bold>). More deeply in time, our modeling indicates that Philippine populations (Kankaney) are the closest outgroup to the First Remote Oceanians, indigenous Taiwanese (Atayal) second closest, and mainland southeast Asians such as Dai most remote, consistent with models of population movement along a route from Taiwan to the Philippines to Near Oceania to Remote Oceania<sup><xref rid="R28" ref-type="bibr">28</xref></sup>. We were surprised that we could not fit Australians as outgroups to New Guinean Highlanders and the Papuan ancestry in Polynesians (<xref rid="F8" ref-type="fig">Extended Data Figure 5</xref>). However, we could fit Australians as deriving from a mixture of an ancient Australian lineage and a Papuan lineage from the same group that expanded into Polynesia. This is plausible if there was continuing gene flow between New Guinea and Australia. Another parsimonious model is that the ancestry in present-day Polynesians is not all Papuan, but a Papuan-Australian mix.</p><p id="P8">Previous studies of mitochondrial DNA and Y chromosomes suggested that present-day people of the South Pacific harbor more East Asian ancestry from female than from male ancestors<sup><xref rid="R3" ref-type="bibr">3</xref></sup>. Our genome-wide analyses confirm a significant excess of First Remote Oceanian ancestry on the X-chromosome compared to the autosomes (<italic>Z</italic>-scores up to 10) (<xref rid="F2" ref-type="fig">Figure 2B</xref>). Females carry 2/3 of X chromosomes in a population but only 1/2 of the autosomes (<xref rid="F9" ref-type="fig">Extended Data Figure 6</xref>), and we compared the ancestry estimates in these two parts of the genome to obtain the most accurate estimates of sex-biased admixture in diverse Oceanians to date (<xref rid="F9" ref-type="fig">Extended Data Figure 6</xref>; <xref rid="T4" ref-type="table">Extended Data Table 4</xref>).

While our findings cannot rule out the possibility that multiple groups—some of which carried substantial amounts of Papuan ancestry—settled Remote Oceania early on, the lack of such ancestry both in Vanuatu and Tonga can be more parsimoniously explained by later population movements bringing the Papuan ancestry. The scenario emerging from ancient DNA analysis is thus radically different from that suggested by previous genetic studies, which have generally posited that the first people in Remote Oceania and Polynesia<sup><xref rid="R2" ref-type="bibr">2</xref>–<xref rid="R5" ref-type="bibr">5</xref></sup> had substantial Papuan ancestry. Our finding of major post-Lapita movements of Papuan ancestry into Remote Oceania also cannot be related to the later arrival of Papuan ancestry that has been suggested for Fiji, which is estimated to have occurred at least a millennium later at 500 BP<sup>4</sup> or 1,100 BP<sup>24</sup> (<xref rid="F2" ref-type="fig">Figure 2</xref>).

The final graph visualized in <xref rid="F3" ref-type="fig">Figure 3</xref> used 10,893 SNPs after restricting to transversion SNPs to avoid complications due to ancient DNA damage and also SNPs with coverage in all groups.

The total number of SNPs after excluding transitions, SNPs with minor allele count of less than 4 in the selected data, and loci where one population had missing data, was 10,119, which we divided into 337 blocks of 30 SNPs each to estimate the covariance matrix. We first fitted a maximum likelihood tree of all populations, but found that several of the fitted allele frequency covariances deviated from those empirically observed by up to 16.4 standard errors. We then used the automated heuristic optimization in <italic>Treemix</italic> to infer a graph model with 1 admixture event using the same populations, and found that the optimal fit was for a model with an admixture event in the history of Tongans, where one portion of their ancestry diverged prior to the split of the ancestors of the ancient Vanuatu and Tonga individuals, and the other (25% ± 3%) derived from the New Guinean lineage.
