The Lapita culture is the name given to a Neolithic Austronesian people and their material culture, who settled Island Melanesia via a seaborne migration at around 1600 to 500 BCE. They are believed to have originated from the northern Philippines, either directly, via the Mariana Islands, or both. They were notable for their distinctive geometric designs on dentate-stamped pottery, which closely resemble the pottery recovered from the Nagsabaran archaeological site in northern Luzon. The Lapita intermarried with the Papuan populations to various degrees, and are the direct ancestors of the Austronesian peoples of Polynesia, eastern Micronesia, and Island Melanesia.
