A team have been testing the mitochondrial DNA, maternal side, of three Native Tribes from the Bristish Columbia region against bodies from 6,000-2,500 years ago and have found matches to living persons from the Nisga, Tsimshian, and Haida tribes. The skeletons came from Dodge Island. One of the 6000 year old skeletons matched DNA from a 10,000 year old skeleton from the same region. This represents one of the longest continuous legacies on earth.
The peoples who comprise the North American Indians crossed the Bering Strait some 20,000 years ago, long before the Adam and Eve of Genesis.
