Researchers have decoded the genome of a Native man who lived in Greenland about 4,000 years ago.

The analysis was based on the man's hair. Researchers say he had brown hair and brown eyes, was susceptible to baldness and had dry ear wax like most Native Americans.

But they say he is more closely related to the indigenous people of Siberia. They say he probably was not an ancestor of Native Americans in Canada or in the United States.

The man belonged to what scientists call the Saqqaq culture. The Saqqaq lived in southern Greenland.

The research is published in Nature.
