DNA study shows Native Americans in Canada 15,000 years ago

Ripan Malhi, professor of anthropology at the University of Illinois, presented DNA research that puts some of the first known Native Americans in Canada as early as 15,000 years ago at the Nov. 18, 2013, session of the meeting, "Ancient DNA: The First Three Decades" at The Royal Society in London

The researchers concentrated their first search for the earliest Native Americans in the Tsimshian Nation on the northwest coast of British Columbia. The Tsimshian Nation was selected as being one of the last Native American cultures to be overcome by Europeans. 
 
Changes in the mitochondrial genome, which children inherit only from their mothers, DNA analysis of ancient human remains in the Prince Rupert Island area, DNA studies of the native peoples living in the region today, and archaeological evidence contributed to the researcher's conclusions.

The relative isolation of the Tsimshian people may have prevented contact with some of the three groups that migrated from China and Russia that became Native Americans. The Tsimshian peoples DNA did undergo some changes through marriage and association with other local cultures.

Malhi plans further investigations of the same kind in California, Guatemala, Mexico and Illinois in hopes of developing a genetic pattern that explains the preference for hunter-gather cultures in some areas of the Americas while farming became the dominant form of life in other regions. examiner.com/
