There's a marker they call "X-factor" that North American Indians share with the Sa'ami and the Berbers. Some groups have as many as 25% of their members sharing the factor (Iriquois, Chippewa) and all have at least 3% sharing it.

South American Indians do not have the factor.

I really don't think the Sa'ami or the Berbers made it to East Asia.

The data also demonstrates a possible 4th migration the actually took place about 15 thousand years ago when Scandinavian Vikings crossed the Atlantic and mixed with Native Americans that crossed the Bering Strait (haplogroup X)."
