 An element in the ancestry of Austronesian-speaking peoples, the one which carried their ancestral language, originated on the island of Taiwan.This occurred after the migration of pre-Austronesian-speaking peoples from continental Asia between approximately 10,000–6000 BCE.Other research has suggested that, according to radiocarbon dates, Austronesians may have migrated from mainland China to Taiwan as late as 4000 BCE (Dapenkeng culture).
