Ancient Genomics and the Peopling of the Southwest Pacific
- Environmental ScienceNature
The 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.
Genetics and the Origins of the Polynesians
The genetic data show how maternal and paternal lineages combined approximately 3000 ybp giving rise to a new people who spoke Austronesian languages and developed a sophisticated technology for oceanic voyaging.

Origins of the Australian and New Guinean Aborigines
Mitochondrial deoxyribonucleic acid (mtDNA), Y chromosome and limited genomic studies indicate deep ancestry for both Australia and New Guinea peoples, with evidence for limited, shared genetic…
Genome-wide data substantiate Holocene gene flow from India to Australia
- Environmental ScienceProceedings of the National Academy of Sciences
An ancient association is found between Australia, New Guinea, and the Mamanwa (a Negrito group from the Philippines), with divergence times for these groups estimated at 36,000 y ago, supporting the view that these populations represent the descendants of an early “southern route” migration out of Africa, whereas other populations in the region arrived later by a separate dispersal.
37 Southeast Asian islands and Oceania: human genetics
This chapter discusses the genetic record of human migration into island Southeast Asia and Oceania, firstly during the Pleistocene, and later during the Neolithic with its associated populations of…
Human genetics of the Kula Ring: Y-chromosome and mitochondrial DNA variation in the Massim of Papua New Guinea
- BiologyEuropean Journal of Human Genetics
It is found that the nearly exclusively Austronesian-speaking Massim people harbor genetic ancestry components of both Asian and Near Oceanian origin, which suggests sex-biased genetic admixture between Asians andnear Oceanians before the occupation of Remote Oceania, in line with the Slow Boat from Asia hypothesis on the expansion of Austronesians into the Pacific.
Ancient DNA from Guam and the Peopling of the Pacific
Ancient DNA data from Guam is analyzed, and it is found that the early Mariana Islanders may have been involved in the colonization of Polynesia, suggesting that the Marianas and Polynesia were colonized from the same source population.
Fine-scale human population structure in southern Africa reflects ecological boundaries
It is estimated that the southern Kalahari populations were among the last to experience gene flow from Bantu-speakers, approximately 14 generations ago, and local adoption of pastoralism appears to have been primarily a cultural process with limited impact from eastern African genetic diffusion.

Genes, language, and culture history in the Southwest Pacific
The book lays out the very complex structure of the variation within and among the islands in this relatively small region, and a number of explanatory models are tested to see which best account for the observed pattern of genetic variation here.
Patterns of Y-chromosome diversity intersect with the Trans-New Guinea hypothesis.
- BiologyMolecular biology and evolution
It is proposed that sex-biased differences in the social structure and cultural heritage of the people involved in the Austronesian and the TNG expansions played an important role (among other factors) in shaping the New Guinean Y-chromosome landscape.
A mitochondrial stratigraphy for island southeast Asia.
- Environmental ScienceAmerican journal of human genetics
It is demonstrated that mitochondrial DNA diversity in the region is extremely high and includes a large number of indigenous clades, suggesting that, if an agriculturalist migration did take place in ISEA, it was demographically minor, at least with regard to the involvement of women.
A predominantly indigenous paternal heritage for the Austronesian-speaking peoples of insular Southeast Asia and Oceania.
- SociologyAmerican journal of human genetics
Using detailed genealogical study of Y chromosome variation, it is shown that the majority of current Austronesian speakers trace their paternal heritage to Pleistocene settlers in the region, as opposed to more-recent agricultural immigrants.
Mitochondrial genome variation and evolutionary history of Australian and New Guinean aborigines.
- BiologyGenome research
The mitochondrial genome data indicate that Australia was colonized between 40 and 70 thousand years ago, either by a single migration from a heterogeneous source population or by multiple movements of smaller groups occurring over a period of time.
Gene flow and natural selection in oceanic human populations inferred from genome-wide SNP typing.
- BiologyMolecular biology and evolution
It is suggested that the major prehistoric human colonizations of Oceania occurred twice, namely, about 50,000 and 4,000 years ago, and indigenous Melanesians are genetically closer to Asians than to Africans and European Americans, which supports the so-called Slow train model.
Multiple dispersals and modern human origins
- Environmental Science
There is no clear rubicon of modern Homo sapiens, and that multiple dispersals occurred from a morphologically variable population in Africa, so pre‐existing African diversity is crucial to the way human diversity developed outside Africa.
The origins of the Polynesians: an interpretation from mitochondrial lineage analysis.
- BiologyAmerican journal of human genetics
It is shown that the major prehistoric settlement of Polynesia was from the west and involved two or possibly three genetically distinct populations, and two Polynesians had unrelated haplotypes matching published sequences from native South Americans, which may be the first genetic evidence of prehistoric human contact between Polynesia and South America.
Mitochondrial DNA variability of West New Guinea populations.
- BiologyAmerican journal of physical anthropology
Analysis of mitochondrial DNA variability in West New Guinea reveals high heterogeneity and an intersecting distribution of genetic variability in these populations, despite their cultural and geographic diversity, which lead to regard these patterns as New Guinea population markers.
Reconstructing Indian-Australian phylogenetic link
- BiologyBMC Evolutionary Biology
The results showing a shared mtDNA lineage between Indians and Australian Aborigines provides direct genetic evidence of an early colonization of Australia through south Asia, following the "southern route".
