[QUOTE]Originally posted by Clyde Winters: [QB] There is no evidence that all Native Americans came from Siberia. In A genomic view of the peopling of the Americas, by Pontus Skoglund, and David Reich. http://genetics.med.harvard.edu/reichlab/Reich_Lab/Welcome_files/SkoglundReich2016_Americas.pdf The authors observed that: “Recently, we carried out a stringent test of the null hypothesis of a single founding population of Central and South Americans using genome-wide data from diverse Native Americans [36""].[b] We detected a statistically clear signal linking Native Americans in the Amazonian region of Brazil to present-day Australo-Melanesians and Andaman Islanders (‘Australasians’).Specifically, we found that Australasians share significantly more genetic variants with some Amazonian populations — including ones speaking Tupi languages — than they do with other Native Americans.[/b] We called this putative ancient Native American lineage ‘Population Y’ after Ypykue´ra, which means ‘ancestor’ in the Tupi language family. To learn more about the Population Y ancestry present in the Americas, we carried out a series of statistical modeling analyses. We found that the patterns of genomic variation of present-day Amazonians could be explained by as little as 2% admixture from an Australasian-related population, that would thus have penetrated deep inside the Americas without mixing with the main ancestral lineage of present-day Native Americans. Alternatively, the patterns could be explained by a larger proportion of ancestry (2–85%) from a population that existed in a substructured Northeast Asia, and was similar to the main lineage that gave rise to other Native Americans while retaining more Australasian affinity.” [/QB][/QUOTE]
