Groundbreaking DNA Research Finds Australasian/Melanesian Ancestry in South America.
DNA studies in 2015 revealed Australasian/Melanesian ancestry in two Indigenous Amazonian groups, the Karitiana and Suruí, Researchers found Australasian ancestry in Indigenous groups living across South America, including those descended from Peru’s Mochica civilization.
They left Siberia 20,000 years ago to Beringia, and left Beringia 15,000 years ago. They are found at the Pre-Clovis site of Monte Verde in Southern Chile 14,800 years ago.
The key to this discovery was locating the genetic Y signal among the groups in the Amazon, on the Brazilian plateau, and in the Peruvian Chotuna people who descended from the Mochica (100-800 CE).
The migrants took a coastal route and split off in the central plateau and the Amazon 15,000-8,000 years ago.
The researchers need to find the Y signal in coastal areas to solidify their claims. And they have to find out why the Y signal has not been found in North or Central America. They may have died out by way of larger groups taking over from the north or the genocide of the Spanish conquest.
The research is published in the Proceedings of the National Academy of Sciences
(My note: There have been many other earlier studies that pointed in this direction. This study brings us closer to the story)
