Reflected upon this map is a new hypothesis of Austronesian expansion, based upon research in linguistics, archaeology and human genetics. The majority of current studies agree that Taiwanese peoples are related both genetically and linguistically to Austronesians now living in southeast Asia and the Pacific, and many sources agree that they probably arrived on the island from mainland China around 6000 years ago. From this point, however, linguistic and genetic hypotheses have diverged: historical linguists and archaeologists have so far supported a model in which Austronesians migrated south through the Philippines to what is now Indonesia, spreading east and west from there. Geneticists, however, have found that many Austronesian populations are more closely related to their mainland Asian ancestors than they are to the Taiwanese, in effect making the Taiwan aboriginal peoples and the Austronesians parallel branches from the same tree.
Also included here are several genetic and archaeological hypotheses of cultural contact and migration, including Blench's (2010) proposal of contact with the Indian subcontinent and Delfin et al.'s (2010) genetic relations with several Australian aboriginal groups.
Rather than viewing Austronesian expansion as a series of straightforward migrations, it seems more and more necessary to delve more deeply into the history and culture of the peoples and the area in order to better reconstruct their history. As further research is undertaken, more of these details will come to light, allowing interdisciplinary scholars to continue improving on what seems to be a solid foundational understanding of the region and its linguistic and genetic history.
