Deconstructing the Lapita Cultural Complex in the Bismarck Archipelago

Within the Pacific Islands, the archaeological phenomenon called the Lapita Cultural Complex is widely regarded as first appearing in the Bismarck Archipelago of Papua New Guinea and then spreading southward. This complex supposedly represents the sudden arrival of migrants from Island Southeast Asia with new technologies, foreign languages, and a different worldview. We question these interpretations and the assumptions behind them and suggest instead that current evidence supports the introduction of new cultural traits over several centuries, rather than the sudden intrusion of foreign migrants.
