The question of the origins of the Polynesians has, for over 200 years, been the subject of adventure science. Since Captain Cook's first speculations on these isolated Pacific islanders, their language affiliations have been seen as an essential clue to the solution. The geographic and numeric centre of gravity of the Austronesian language family is in island Southeast Asia, which was therefore originally seen as their dispersal homeland. However, another view has held sway for 15 years, the…

The Role of Migration , Trade , and Genetic Exchange in the Neolithic Austronesian Expansion
Insular Southeast Asia’s (ISEA) Neolithic past invokes the idea of the “Austronesian expansion” into the Malay Archipelago, and the consequent supplanting of a preexisting, hunter-gatherer population
A mitochondrial stratigraphy for island southeast Asia.
TLDR
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.
Early Peopling of the Pacific: Paleoanthropology, Genetic and Linguistic Perspectives
The question about the origins of Polynesians people has been the subject of hot debate. There are two principal hypotheses concerning Polynesian ancestry, there are called as “Express Train” (Asia
Taiwan Austronesian language heritage connecting Pacific Island peoples: Diplomacy and values
As we engage in the current Pacific arena of diplom acy and cultural values, the position of Taiwan as an early linguistic factor in the dispersal of its languages is important to observe. The region
Resolving the ancestry of Austronesian-speaking populations
TLDR
A primarily common ancestry for Taiwan/ISEA populations established before the Neolithic, but also detected clear signals of two minor Late Holocene migrations, probably representing Neolithic input from both Mainland Southeast Asia and South China, via Taiwan.
Contrasting Linguistic and Genetic Origins of the Asian Source Populations of Malagasy
TLDR
Surprisingly, the Ma’anyan are characterized by a distinct, high frequency genomic component that is not found in Malagasy, which hints at a more complex model for the Austronesian expansion in this region.
The Austronesian Moment
For nearly a decade now the debate has quickened on the origins of the Austronesian Peoples of East and Southeast Asia who migrated eastward into Island Southeast Asia and the Western Pacific. There
Austronesian genetic signature in East African Madagascar and Polynesia
TLDR
The results indicate that while Madagascar derives 66.3% of its genetic makeup from Africa, a clear connection between the East African island and Southeast Asia can be discerned and suggest that although geographic location has influenced the phylogenetic relationships between Austronesian populations, a genetic connection that binds them beyond geographical divides is apparent.
Farming and Language in Island Southeast Asia
Current portrayals of Island Southeast Asia (ISEA) over the past 5,000 years are dominated by discussion of the Austronesian “farming/language dispersal,” with associated linguistic replacement,
Genetic characterization of four Austronesian-speaking populations
TLDR
The results indicate that the east-African population from Madagascar phylogenetically segregates intermediate between mainland east- African and east-Asian groups, corroborating linguistic data indicating the Austronesian influence on this population.

Polynesian origins: Slow boat to Melanesia?
TLDR
The new evidence implies that the Polynesians originated not in China/Taiwan, but in eastern Indonesia, somewhere between Wallace's line and the island of New Guinea.
The Peopling of the Pacific
TLDR
Some scientists are converging on a model that involves mingling between Austronesian speakers, perhaps from Taiwan or nearby areas, and the indigenous people of Melanesian islands such as Papua New Guinea, which created a people that swept out into the remote Pacific islands.

TLDR
Southeast Asia provided a genetic source for two independent migrations, one toward Taiwan and the other toward Polynesia through island Southeast Asia, according to the Y-chromosome data.
A predominantly indigenous paternal heritage for the Austronesian-speaking peoples of insular Southeast Asia and Oceania.
TLDR
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.
The origins of the Polynesians: an interpretation from mitochondrial lineage analysis.
TLDR
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 variation is an indicator of austronesian influence in Island Melanesia.
TLDR
The hypothesis that this deletion was first introduced to this region about 3,500 years ago with the arrival of Austronesian-speaking peoples from the west has not yet diffused through all populations there, and cannot be reconciled with the competing hypothesis of a primarily indigenous Melanesian origin for the ancestors of the Polynesians.
