Yapese is one of several problematic languages that can be shown to be Austronesian but that share little vocabulary with more typical languages. Other languages of this category are Enggano, spoken on a small island of the same name situated off the southwest coast of Sumatra, and a number of Melanesian languages.Where did the Austronesian people originally come from?
An element in the ancestry of Austronesian-speaking peoples, the one which carried their ancestral language, originated on the island of Taiwan.How is the admixture of Austronesian and Papuan?
In Polynesians in Remote Oceania, for example, the admixture is around 20 to 30% Papuan, and 70 to 80% Austronesian. The Melanesians in Near Oceania are roughly around 20% Austronesian and 80% Papuan, while in the natives of the Lesser Sunda Islands, the admixture is around 50% Austronesian and 50% Papuan.What was the evidence for the Austronesian expansion?
Most of the evidence supporting the Austronesian Expansion is linguistic. In the late 1970s, linguist Robert Blust of University of Hawaii defended the theory by breaking down the Proto-Austronesian language groups into subdivisions and linking these divisions back to Taiwan.
