Humans island-hopped to Polynesia: Genetic Study

By HT School,

Between 9th and 14th centuries, humans migrated across 1000 Polynesian islands.

Mankind carried statues to the Polynesian archipelagos, also known as moai.

People who created megaliths on the north and west of the famous Easter islands apparently have relatives on the nearby Polynesian islands. This was revealed through a recently conducted genetic study. Throughout 250 years, people in and around Tahiti group of islands have migrated to settle in the Polynesian archipelagos. Polynesia covers one-third of earth’s surface area, spread across thousand miles, but all having same types of statues. Polynesia was earth’s last habitable region situated between central and southern Pacific Ocean and is a part of Oceania. Between 830 and 1360 AD, the settlements began in Samoa and had spread across entire Pacific region. The statues are known as moai (only has head and torso) that covers an area from the Cook Islands, to the Society islands, followed by Austral islands and finally Marquesas and Easter islands. These island-hoppings were guided by seabirds, stars, ocean currents and other natural sources. The present day trans-Pacific people share their genes with such ancient humans, the DNA of whom was found on the existing megaliths. Their origin is said to be from Tuamotus, a certain kind of megalith sites. However, current Polynesian population (430 in number) have mixed DNAs, both from ancient and modern ancestors (17 generations in total), as revealed by Alexander Ioannidis, the lead researcher, whose team drew a family tree from the genetic clues they unearthed.
