Through Ethnicity

Ethno-linguistic groups classified as Micronesian include the Carolinians (Northern Mariana Islands), Chamorros (Guam & Northern Mariana Islands), Chuukese, Mortlockese, Namonuito, Paafang, Puluwat and Pollapese (Chuuk), I-Kiribati (Kiribati), Kosraeans (Kosrae), Marshallese (Marshall Islands), Nauruans (Nauru), Palauan, Sonsorolese, and Hatohobei (Palau), Pohnpeians, Pingelapese, Ngatikese, Mwokilese (Pohnpei), and Yapese, Ulithian, Woleian, Satawalese (Yap).

Origins

Based on the current scientific consensus, the Micronesians are considered, by linguistic, archaeological, and human genetic evidence, to be a subset of the sea-migrating Austronesian people, who include the Polynesians and the Melanesians. Austronesians were the first people to invent oceangoing sailing technologies (notably double-hulled sailing canoes, outrigger boats, lashed-lug boat building, and the crab claw sail), which enabled their rapid dispersal into the islands of the Indo-Pacific. From 2000 BCE the Austronesians assimilated (or were assimilated by) the earlier populations on the islands in their migration pathway. This intermingling occurred in the northern coast of New Guinea and adjacent islands, which was the location where the Oceanic language family developed around four thousand years or so ago, after the Austronesian languages of this area grew distinct and became a separate branch of the Austronesian family.

Migrants entered Micronesia from the east and the west. Migrants from the west came from the Philippines and Indonesia, and settled the Marianas around 3500 years ago, after which Palau was settled around 3000 years ago. Migrants from the east came from eastern Melanesia and settled the Gilbert Islands, Marshall Islands, eastern and central Caroline Islands, Sonsorol, Pulo Anna, Merir and Tobi. The migrants from the east belonged to the Lapita culture and settled eastern Micronesia over the course of several hundreds of years from perhaps the Santa Cruz Islands, around 500-100 BC. In the following centuries, the Oceanic language variant brought by the Lapita migrants diverged and became the Micronesian branch of the Oceanic languages. John Lynch tentatively proposes a relationship between the Micronesian languages and the Loyalty Islands languages of Melanesia, but with the caveat "that this is something that could well be further investigated, even if only to confirm that Micronesian languages did not originate in the Loyalties." Yap was settled separately approximately 2000 years ago, as its language was brought by an Oceanic-speaking source in Melanesia, perhaps the Admiralty Islands.

A 2022 genetic study has shown that the various peoples inhabiting Micronesia have diverse genetic origins and originate from distinct streams of migration. Micronesia was settled by three separate streams of First Remote Oceanian lineage, which corresponds to East Asian ancestry and clusters closely to modern day peoples of the Philippines such as the Kankanaey and the Amis and Atayal of Taiwan. The first wave of First Remote Oceanian lineage settled the Mariana Islands around 2800 BCE. A second separate wave settled Palau around 2400 BCE. A third separate wave settled Central Micronesia around 2100 BCE. The peoples of Central Micronesia and Palau have a degree of Papuan ancestry, but this is absent from the peoples of the Mariana Islands. The study also supports the Admiralty Islands as the source of the Central Micronesian peoples and languages.
