The Lapita complex is part of the eastern migration branch of the
Austronesian expansion, which started from Taiwan between about 5,000 and 6,000 years ago. Some of the emigrants reached Melanesia and were distant descendants of much earlier migrations into the super-continent of
Sahul. There are different theories about the route they took to get there. They may have gone through the
Marianas Islands, or through the
Philippines, or both. The strongest support for the theory that the original people of the Lapita culture were Austronesian is linguistic evidence showing very considerable
lexical continuity between
Proto-Malayo-Polynesian (presumably spoken in the Philippines) and
Proto-Oceanic (presumably spoken by the Lapita people). In addition, the patterns of linguistic continuity correspond to patterns of similarity in material culture. across the
Indo-Pacific In 2011, Peter Bellwood proposed that the initial movement of Malayo-Polynesian speakers into Oceania was from the northern Philippines eastward into the
Mariana Islands, then southward into the Bismarcks. An older proposal was that Lapita settlers first arrived in Melanesia via eastern Indonesia. Bellwood's proposal included the possibility that both migration patterns happened, with different migrants taking different routes. Bellwood's proposal is supported by the pottery evidence: Lapita pottery is more similar to pottery recovered from the Philippines (at the Nagsabaran archaeological site on
Luzon Island) than it is to pottery discovered anywhere else. Other evidence suggests that the Luzon area may have been the original homeland of the stamped pottery tradition that is carried forward in Lapita culture. The
Mana skeleton, a complete skeleton of a Lapita woman that lived in
Fiji in 800 BCE, had her face
reconstructed with the use of computer modelling. Her facial features bear similarities to those typically associated with
Polynesian,
Fijian and
Asian ancestry, however she does not clearly align with any one of these groups. This evidence of the Lapita peoples' migration route was corroborated in 2020 by a study that did a complete
mtDNA and
genome-wide SNP comparison of the remains of early settlers of the
Mariana Islands with the remains of early Lapita individuals from
Vanuatu and
Tonga. The results suggest that both groups had descended from the same ancient Austronesian source population in the
Philippines. The complete absence of "Papuan" admixture in these remains suggest that the voyages of the migrants bypassed eastern
Indonesia and the rest of
New Guinea. The study authors noted that their results also support the possibility that early Lapita Austronesians were direct descendants of the early colonists of the Marianas (who preceded them by about 150 years); this idea is also consistent with the pottery evidence. Recent DNA studies show that the Lapita people and modern
Polynesians have a common ancestry with the
Atayal people of Taiwan and the
Kankanaey people of the northern Philippines. A 2023 study states that Lapita people already have increased Northeast Asian ancestry (~21–29%) compared to ancient groups that initially settled in Taiwan (~0–8%). ==Discovery==
