Domesticated plants and animals of Austronesia

One of the major human migration events was the maritime settlement of the islands of the Indo-Pacific by the Austronesian peoples, believed to have started from at least 5,500 to 4,000 BP (3500 to 2000 BCE). These migrations were accompanied by a set of domesticated, semi-domesticated, and commensal plants and animals transported via outrigger ships and catamarans that enabled early Austronesians to thrive in the islands of maritime Southeast Asia, near Oceania, remote Oceania, Madagascar, and the Comoros Islands.

They include crops and animals believed to have originated from the Hemudu and Majiabang cultures in the hypothetical pre-Austronesian homelands in mainland China, as well as other plants and animals believed to have been first domesticated from within Taiwan, maritime Southeast Asia, and New Guinea. These plants are often referred to as "canoe plants", especially in the context of the Polynesian migrations. Domesticated animals and plants introduced during historic times are not included.

Domesticated, semi-domesticated, and commensal plants carried by Austronesian voyagers include the following:

The candlenut (Aleurites moluccanus) was first domesticated in Island Southeast Asia. Remains of harvested candlenuts have been recovered from archaeological sites in Timor and Morotai in eastern Indonesia, dated to around 13,000 BP and 11,000 BP respectively. Archaeological evidence of candlenut cultivation is also found in Neolithic sites of the Toalean culture in southern Sulawesi dated to around 3,700 to 2,300 BP. Candlenut were widely introduced into the Pacific Islands by early Austronesian voyagers and became naturalized to high volcanic islands.

Candlenut has a very wide range of uses and every part of the tree can be harvested. They were primarily cultivated for the high oil content in their nut kernels. They were used widely for illumination, prior to the introduction of other light sources, hence the name "candlenut". The kernels were skewered on coconut midribs that were then set alight. Each kernel takes about three minutes to burn and thus the series could act as a torch. This tradition of making candlenut torches exists in both Southeast Asia and Oceania. Candlenut oil extracted from the nuts can also be used directly in lamps. They can also be utilized in the production of soaps, ointments, and as preservatives for fishing gear. Other traditional uses include using the timber for making small canoes and carvings; the sap for varnish and resins; the nut shells for ornamentation (most notably as leis), fish-hooks, toys, and the production of black dyes; the bark for medicine and fiber; and so on. Some non-toxic varieties are also used as condiments or ingredients in the cuisines of Southeast Asia and the Pacific.

The Proto-Malayo-Polynesian word for candlenut is reconstructed as *kamiri, with modern cognates including Hanunó'o, Iban, and Sundanese kamiri; Javanese and Malay kemiri; and Tetun kamii. However the Oceanian words for candlenut are believed to be derived instead from Proto-Austronesian *CuSuR which became Proto-Malayo-Polynesian *tuhuR, originally meaning "string together, as beads", referring to the construction of the candlenut torches. It became Proto-Eastern-Malayo-Polynesian and Proto-Oceanic *tuRi which is then reduplicated. Modern cognates including Fijian, Tongan, Rarotongan, and Niue tui-tui; and Hawaiian kui-kui or kukui.

The giant taro (Alocasia macrorrhizos) was originally domesticated in the Philippines, but are known from wild specimens to early Austronesians in Taiwan. From the Philippines, they spread outwards to the rest of Island Southeast Asia and eastward to Oceania where it became one of the staple crops of Pacific Islanders. They are one of the four main species of aroids (taros) cultivated by Austronesians primarily as a source of starch, the others being Amorphophallus paeoniifolius, Colocasia esculenta, and Cyrtosperma merkusii, each with multiple cultivated varieties. Their leaves and stems are also edible if cooked thoroughly, though this is rarely done for giant taro as it contains higher amounts of raphides which cause itching.

The reconstructed word for giant taro in Proto-Austronesian is *biRaq, which became Proto-Oceanic *piRaq. Modern cognates for it in Island Southeast Asia and Micronesia include Rukai vi'a or bi'a; Ifugao bila; Ilocano, Cebuano, and Bikol biga; Tiruray bira; Ngaju biha; Malagasy via; Malay and Acehnese birah; Mongondow biga; Palauan bísə; Chamorro piga; Bima wia; Roti and Tetun fia; Asilulu hila; and Kowiai fira. In Oceania, cognates for it include Wuvulu and Aua pia; Motu and ꞋAreꞌare hira; Kilivila and Fijian via; and Hawaiian pia. Note that in some cases, the cognates have shifted to mean other types of taro.
