Linguist: Three of the four subfamilies of the so-called Austronesian languages are found only among indigenous peoples in Taiwan, whereas the fourth is found on islands over a huge area stretching from Madagascar to the eastern Pacific Ocean
Since these subfamilies all originated in the same language, which must have been originally spoken in a single geographic location, these facts suggest that Taiwan is the homeland where Austronesian languages have been spoken longest and, hence, that Austronesian-speaking peoples originated in Taiwan and later migrated to other islands
Austronesian-speaking peoples probably originated in Taiwan and later migrated to other islands.
