Diane's material itself is fascinating. To quote:
A study published in the May issue of Molecular Biology and Evolution claims all modern-day Native people descend from a single group.
Researchers examined the DNA from 20 Native groups in the U.S., Canada, Greenland, Central America and South America. They found a common genetic marker in all of the populations.
The genetic marker was not found in the DNA of 31 modern-day Asian groups, leading researchers to conclude that the ancestors of modern-day Native people lived in isolation before expanding to the Americas. The study estimates the most recent common ancestor lived somewhere between 7,325 and 39,900 years ago.
The marker was found in two Native groups in Western Siberia, in Russia, that are closely linked to Alaska Natives.

Howdy, my friend! I appreciated your help in getting Diane's permission to use her information. And I enjoyed rereading the original article.
It is truly is a small world as we learn more and more about humans migrated all over the earth out of Africa.
Have a good day. Namaste!
