Where is native americans came from

They found that while most Native American populations descend primarily from one migration, there were two later ones that also made a significant genetic contribution. The later migrants probably arrived in boats, after the land-bridge disappeared at the end of the ice ages. In a press statement, Ruiz-Linares explains that for years there has been a debate about whether the settlement of the Americas came from one or several migrations out of Siberia.

The findings confirm what linguist Joseph Greenberg proposed in From studying language differences among Native Americans, he said the Americas must have been populated in three waves of migration. The analysis also showed that once these waves of migrations arrived in the Americas, the groups expanded southwards, hugging the coastline, splitting off along the way.

After they split off, the groups mixed very little with each other, especially the ones that ended up in South America. We think of the arrival of the first people as one group braving their way across a land bridge, when in fact it was many groups, many different languages, and technologies arriving at different times from different directions. It is this complex story of many people, with many different stories.

The most fascinating place I saw was a back woods river south of Tallahassee, Florida, where human evidence from 14, years ago was found. For me, this was a new beginning, a way of coming into my own continent. Simon Worrall curates Book Talk. Follow him on Twitter or at simonworrallauthor. All rights reserved. Share Tweet Email.
