 These populations are genetically distinct from later Austronesians, but through fairly extensive population admixture, most modern Austronesians have varying levels of ancestry from these groups.The same is true for some populations historically considered "non-Austronesians" due to physical differences; like Philippine Negritos, Orang Asli, and Austronesian-speaking Melanesians, all of whom have Austronesian admixture.In Polynesians in Remote Oceania, for example, the admixture is around 20 to 30% Papuan, and 70 to 80% Austronesian.
