The Lapita Cultural Complex--first uncovered in the mid-20th century as
a widespread archaeological complex spanning both Melanesia and Western
Polynesia--has subsequently become recognized as of fundamental
importance to Oceanic prehistory. Notable for its highly distinctive,
elaborate, dentate-stamped pottery, Lapita sites date to between
3500-2700 BP, spanning the geographic range from the Bismarck
Archipelago to Tonga and Samoa. The Lapita culture has been interpreted
as the archaeological manifestation of a diaspora of
Austronesian-speaking people (specifically of Proto-Oceanic language)
who rapidly expanded from Near Oceania (the New Guinea-Bismarcks region)
into Remote Oceania, where no humans had previously ventured. Lapita is
thus a foundational culture throughout much of the southwestern Pacific,
ancestral to much of the later, ethnographically-attested cultural
diversity of the region.
