A survey of wild and domestic pigs has caused archaeologists to reconsider both the origins of the first Pacific colonists and the migration routes humans travelled to reach the remote Pacific.


Scientists from Durham University and the University of Oxford, studying DNA and tooth shape in modern and ancient pigs, have revealed that, in direct contradiction to longstanding ideas, ancient human colonists may have originated in Vietnam and travelled between numerous islands before first reaching New Guinea, and later landing on Hawaii and French Polynesia.

Using mitochondrial DNA obtained from modern and ancient pigs across East Asia and the Pacific, the researchers demonstrated that a single genetic heritage is shared by modern Vietnamese wild boar, modern feral pigs on the islands of Sumatra, Java, and New Guinea, ancient Lapita pigs in Near Oceania, and modern and ancient domestic pigs on several Pacific Islands.
