Origin and genetics

East Eurasians.

Schematic summary of population settlement in Insular Southeast Asia, involving several East Eurasian lineages: (A) Initial occupation of Sunda and Sahul by ancestry related to modern New Guinean and Australian Aboriginal populations, followed by deep mainland Asian (Tianyuan- or Onge-related) ancestry. (B) Dispersals of ancestries associated with ancient Mainland Southeast Asian and ancestral Punan-related components predating the coastal South Chinese, and hence Austronesian-related, ancestries. (C) Austronesian expansion leading to Austronesian (Ami- and Kankanaey-related) ancestry observed in NE and SE Borneans and subsequent specific Papuan ancestry admixture observed in the Lebbo population in East Borneo.

The origin of Papuans is generally associated with the first settlement of Australasia by a lineage dubbed 'Australasians' or 'Australo-Papuans' during the Initial Upper Paleolithic, which is "ascribed to a population movement with uniform genetic features and material culture" (Ancient East Eurasians), and sharing deep ancestry with modern East Asian peoples and other Asia-Pacific groups.^[10][11][12] It is estimated that people reached Sahul (the geological continent consisting of Australia and New Guinea) between 50,000 and 37,000 years ago. Rising sea levels separated New Guinea from Australia about 10,000 years ago. However, Aboriginal Australians and Papuans had diverged genetically much earlier, around 40,000 years BP. Papuans are more closely related to Melanesians than to Aboriginal Australians.^[13][12]

Haplogroups

The majority of Papuan

The genetic makeup of Papuans is primarily derived from Ancient East Eurasians, which relates them to other mainland Asian groups such as the "AASI", Andamanese, as well as East/Southeast Asians, although Papuans may have also received some gene flow from an earlier group (xOoA), around 2%,^[16] next to additional archaic Denisovan admixture in the Sahul region. Papuans may habor varying degrees of deep admixture from "a lineage basal to West and East-Eurasians which occurred sometimes between 45 and 38kya", although they are generally regarded "as a simple sister group of Tianyuan" ("Basal East Asians").^[11][12][10]

There is evidence that the ancestors of Papuans and related groups "underwent a strong bottleneck before the settlement of the region, and separated around 20,000–40,000 years ago".^[17]

Papuans display pronounced genetic diversity, explained through isolation and drift between different subgroups after the settlement of New Guinea. The most notable differentiation was found to be between Highlanders and Lowlanders. Papuan Highlanders fall into three clusters, but form a single clade compared against Lowlanders. The Highlanders underwent a population bottleneck around 10,000 years ago, associated with the adaption of Neolithic lifestyles. Papuan Lowlanders display increased diversity and can be broadly differentiated into a Southern Lowlander cluster and a Northern Lowlander cluster. The genetic differentiation among Papuans is suggested to date back at least 20kya, while the sub-structure among Highlanders dates back around 10kya, with higher diversity among western Highlanders than Eastern ones. The genetic diversity is paralleled by linguistic and cultural diversity.^[18]

Archaic introgression

Based on his genetic studies of the

In a 2005 study of ASPM gene variants, Mekel-Bobrov et al. found that the Papuan people have among the highest rate of the newly evolved ASPM Haplogroup D, at 59.4% occurrence of the approximately 6,000-year-old allele.^[21] While it is not yet known exactly what selective advantage is provided by this gene variant, the haplogroup D allele is thought to be positively selected in populations and to confer some substantial advantage that has caused its frequency to rapidly increase.
