DNA Sheds New Light on Polynesian Migration

New genetic research reveals that the migratory story of the Polynesians may be more ancient and complicated than previously thought.

For years, it was generally accepted that Polynesians originated in modern-day Taiwan and began moving south and east about 4,000 years ago. This migration account is based on the research of linguists, the findings of archeologists and some genetic analysis.

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 and may have caused a language shift.”

The original migration from the mainland may have had to do with natural climate change.

“They may have just ended up there because of sea level rises occurring at the time, and the formation of an archipelago,” Dr. Richards said.

I dont believe that. Nobody knows polynesians history even if the white man man were to write it. I for one could only say are history is lost. otherwise its known through elders by tongue. icon_neutral.gif

i still dont understand how these people end up at hawaii. That is so far away from everywhere especially thousands of years ago.

You look at the most "pure" ones and the bone structure correlates with recent migration. Not to be mean, but when you look at a "pure" Australian Aborigine and you know they've been separate from 10ths of thousand to millions of years from the rest of mankind. So yeah I see your point.

The Pacific ocean is much calmer than the Atlantic, and it's way easier to travel out to sea on a canoe. You may have some rain to deal with but that's about it. Ancient seafarers looked for cloud cover in the far distance to detect the presence of new landmass.

The Pacific Ocean is calmer than the Atlantic, although it is wider. The Pacific islands also form a bit of string at some places, so that may have helped also. In the Atlantic, there are the Azore islands, but apparently very little islands between Europe and the Americas. But more importantly, what helped Polynesians, Micronesians, and Melanesians colonize the Pacific Ocean and arrive in the Americas (in the case of the Polynesians) was the development of the outrigger and double hull (catamaran) canoes, and also sailing technology. They did have a navigation system based upon the stars. They did not sail blindly into the unknown. They also invented sun screen lotion which protected their skin from radiation during their long voyages. Their bodies also seem to have evolve to have more fat cells allowing them to survive long voyages when food resources became more leaner. By the way those "canoes", are actually large shipping vessels. They used large ships to carry people in their voyages and migrations.

Hawaii was probably discovered by accident. people get lost at sea all the time (even Columbus got lost)
