The immediate origins of the Lapita lay to the northwest, in the Solomon Islands and the Bismark Archipelago of Papua New Guinea, though DNA studies of a 3,000-year-old skeleton found near Port Vila in 2016 indicates that some may have arrived directly from the Philippines and/or Taiwan, pausing only briefly en route. They brought with them crops such as yam, taro and banana, as well as domesticated animals such as pigs and chickens. Their arrival is coincident with the extinction of several species, such as the land crocodile (''Mekosuchus kalpokasi''), land tortoise (''Meiolania damelipi'') and various flightless bird species. Lapita settlements reached as far east as Tonga and Samoa at their greatest extent.
