Over time it is thought that the Lapita either mixed with, or acted as pioneers for, migrants coming from the Bismarks and elsewhere in Melanesia, ultimately producing the darker-skinned physiognomy that is typical of modern ni-Vanuatu. Linguistically, however, the Lapita peoples' Austronesian languages were maintained, with all of the numerous 100+ autochthonous languages of Vanuatu being classified as belonging to the Oceanic branch of the Austronesian language family.
