But a new study in The American Journal of Human Genetics reports that Polynesians began migrating thousands of years earlier, not from Taiwan, but from mainland Southeast Asia. The study looked at mitochondrial DNA, which gives information about maternal ancestry. The researchers compared DNA samples from more than 4,700 people in Southeast Asia and Polynesia. Based on this, they determined that Polynesians arrived in the Bismarck Archipelago of Papua New Guinea at least 6,000 to 8,000 years ago, via Indonesia, and presumably left the mainland about 10,000 years ago. Linguists believe that Polynesian languages belong to the Austronesian language family, which originated in Taiwan. Though the new research seems to leave the linguists in the lurch, Martin Richards, an archaeogeneticist at the University of Leeds in Britain and one of the study’s authors, believes there might be a reasonable explanation. “It’s still possible there was the elite movement from Taiwan much later that transferred the language,” he said. “The idea would be that we do have very minor lineages that look like they came to Bismarck about 3,500 years ago
