range from 16.000 to 22.000 years ago, According to the hypothesis ice bridge.Native American Haplogroup affiliation and TestingAlthough an Increasing number of laboratories offering DNA tests are DNA tests for Native American Y chromosome and mitochondrial DNA, it is important to note That these results are not currently Recognized as sufficient proof to become a registered Native American. Moreover, due to the fact That each of the four major mtDNA haplogroups found in different tribal groups in North America, Central and South America, the Native American DNA test will not Provide a specific tribal affiliation.Member famous Native American HaplogroupsThe Ice Maiden "Juanita" was Discovered on Mount Ampato's Peru, near Arequipa, Peru in 1995 by Johann Reinhard. "Juanita," who lived about 500 years ago, was sacrificed in a religious ceremony around the age of 14 years. Scientists have recovered the DNA of the Ice Maiden and determined That It belonged to the Native American haplogroup A2, and she was Closely related to the Panamanian Ngobe Indian tribe.ReferencesTorroni A, Schurr TG, et al.

From August 262003, Oxford Ancestors searchable database lists 39 games for Aiyana.According to Oxford Ancestors:Aiyana... the founder of one of the four major clans who colonized North America and South East Asia about 12.000 years ago. Descendants Aiyana Fought extreme cold and ice As They crossed the Bering land bridge That joined what is now Alaska and Siberia, to reach the Great Plains of North America. From there, They spread to reach all parts of the continent and, Within just a few thousand years, all of Central America and South America as well. However, Given the data currently available, it is not possible to determine precisely where Aiyana lived or even when.The descendants of four clans - Chochmingwu, Djigonasee, Aiyana and Ina - dominate the Native Americans. In addition, about 1% of Native Americans are found to belong to the clan of Xenia, Which had its origins on the borders of Europe and Asia. The clans Chochminwu, Djigonasee Aiyana and can be found in modern inhabitants of Siberia and Alaska, but this is not the case of Ina. Their descendants are found in Central and South America, but only the far north Vancouver Island in the northwestern Pacific coast. Interestingly, this is Also the same clan that is Closely Associated with
