The first settlers of Bougainville were Melanesians, likely related to present-day Papuans and Aboriginal Australians. Approximately 3,000 years ago, a wave of Austronesian peoples arrived in Bougainville, bringing with them the Lapita culture. The Austronesians brought with them a fully agricultural lifestyle, also introducing distinctive pottery and domesticated pigs, dogs and chickens to Bougainville. The advent of the Lapita culture resulted in "a pattern of apparent extinctions of birds and endemic mammals". Both Austronesian and non-Austronesian languages (historically called "East Papuan") continue to be spoken on Bougainville today. There has been substantial genetic and cultural mixing between the Austronesian and non-Austronesian populations, "such that language is no longer correlated with either genetics or culture in any direct or simplistic way".
