Got a tip? And a study of 27 modern people from Rapa Nui found they had Native American ancestry dating back to between C. They analyzed genome-wide data from people from the island.
Comparing those sequences with genomes from people from 15 Indigenous groups from the Pacific coast of Latin America, researchers found most similarity to the Zenuan Indigenous group from Colombia, the team flirt Burlington NC today in Nature. Analyses of the length of the Native American sequences show this ancestry appeared first on Fatu Hiva in the South Marquesas roughly 28 generations ago, which would date it to about C.
The genetic legacy of that mixing was then carried by Polynesian voyagers as they settled other islands, including Rapa Nui. Modern Latin American fishermen lost at sea have been known to drift all the way to Polynesian islands.
Science Insider. Epidemiology Do chronic infections breed dangerous new variants? The work strengthens earlier evidence that somewhere—perhaps on the northern coast of South America—the two groups met and mixed well before the free meeting space Tacoma of European colonialism.
Scientists map urban heat islands—and track how communities are affected By Anil Oza Aug. By Alex Viveros Aug. Scientists urged Wisconsin to limit its wolf kill. Polynesian voyagers frequently traveled between islands and could have journeyed to South America and back, perhaps multiple times, Fox says. By about C. Guided by subtle dating vietnamese Joliet IL girl of wind and waves, the paths of migrating birds, bursts of light from bioluminescent plankton, and the position of the stars, they reached and settled islands from New Zealand to Rapa Nui, or Easter Island, the closest Polynesian island to South America.
But they were also able to detect a small amount of Native American ancestry in people from the eastern Polynesian islands of Palliser, the Marquesas, Mangareva, and Rapa Nui. The Native American sequences were short and nearly identical—seemingly a legacy of one long-ago meeting with a Native American group, rather than sustained contact over generations, Moreno-Estrada says.
By Meredith Wadman Aug. By Mennatalla Ibrahim Aug. All rights Reserved. Then they combined those data with genomic analyses of Polynesian people from 16 other islands, whose genetic samples had been collected in the s.

Moreno-Estrada, Sandoval, and their team found that people on many islands had both Polynesian and European ancestry, reflecting their colonial histories. Earlier sex in the Murfreesboro TN dating of contact between the two regions included the sweet potato, which was domesticated in the Andes but grown and eaten all over Polynesia for hundreds of years before Europeans arrived.

And Kennewick nsa message board shakes up the most popular model of where Native American genes first took root in Polynesia, shifting the focus from Rapa Nui to islands farther west. How to contact the news team.
A genomic study of more than modern Polynesians and Native Americans suggests they did. To move forward, he says, researchers need to deeply engage on an ongoing basis with descendant communities on many islands.
