Piggies Across The Pacific

Scientists are tracking the dispersal of humans across the scattered islands of the Pacific Ocean by following the genetic markers of feral pigs. While pigs can swim, the distances between the islands are too great, meaning their porcine subjects could only have arrived via human effort. And what they have found is a clear link between pigs in Vietnam and Indonesia with pigs in Oceania. This goes against the traditional view that the Pacific Islands were peopled by humans from Taiwan and the Philippines.
