America's First Immigrants: DNA Links Native Americans, Indigenous Canadians To First Ancient Migration

DNA proves that Native American and indigenous Canadian groups along the northern Pacific Ocean have been living there for more than 10,000 years.
Scientists did a genetic analysis on people from the British Columbia coast and southern Alaska and compared it with samples from ancient skeletons to show the connection to the humans who first settled North America, according to a study in the Proceedings of the National Academy of Sciences.
