Prehistory

Evidence of human settlement in Taiwan dates back thirty thousand years, although the first inhabitants of Taiwan may have been genetically distinct from any groups currently on the island. About four thousand years ago, ancestors of current Taiwanese aborigines settled in Taiwan. These aborigines are genetically related to Malay and Polynesians, and linguists classify their languages as Austronesian.[1] Polynesians are suspected to have ancestry traceable back to Taiwan.

Early settlement
Han Chinese began settling in the Pescadores in the 1200s, but Taiwan's hostile tribes and its lack of the trade resources valued in that era rendered it unattractive to all but "occasional adventurers or fishermen engaging in barter" until the sixteenth century.[2]
Records from ancient China indicate that Han Chinese might have known of the existence of the main island of Taiwan since the Three Kingdoms period (third century, 230 A.D.), having assigned offshore islands in the vicinity names like Greater Liuqiu and Lesser Liuqiu (etymologically, but perhaps not semantically, identical to Ryūkyū in Japanese), though none of these names has been definitively matched to the main island of Taiwan. It has been claimed but not verified that the Ming Dynasty admiral Cheng Ho (Zheng He) visited Taiwan between 1403 and 1424.
