Ancient Hair Reveals Greenland Eskimos' Roots : NPR: "And the hair yielded something extremely rare — the DNA of some of the earliest humans to live in the Arctic. By studying that DNA, researchers say they've been able to answer a longstanding question: Are modern Eskimos descended from ancient Native Americans, or did they come from somewhere else?
The answer, according to a new study published in the current issue of the journal Science, is somewhere else — probably eastern Asia."
