I think they (Ainu) or someone like them made it here in ancient times.

There is a subrace in the islands off the coast of Asia (Japan, Taiwan, Polynesia): the Ainu (the original inhabitants of the Japanese islands) are the northerly branch of this group. Polynesians (originally from Taiwan) the southern branch. How they got across the Pacific I don't know, but they got there before the southern Pacific was settled.

Mitochondrial DNA type B is found most commonly in Great Basin, US Southwest, Meso-America, and northern S America - some of the Pueblo tribes have the highest percentage of this MtDna group (like 88%). Yet B is totally missing from Siberia. It is almost non-existent in Alaska and most of Canada. MtDna B is common in SE Asia, particularly among Polynesians.

This guy supports the Ainu-Polynesian theory of some NA origins:

At present, Jantz is one of eight anthropologists, including several morphometricians, who are suing the federal government for access to further study the bones of Kennewick Man, found in 1996 on the banks of the Columbia River near Kennewick, Washington, and currently locked away in a vault at the University of Seattle. No DNA could be recovered from Kennewick Man, but carbon dating of bone collagen set the skeleton’s age at 9,000 years. Under the Native American Graves Protection and Repatriation Act, local Indian tribes have requested the skeleton for re-burial. What makes the situation significant — and politically charged — is that physical anthropologists say Kennewick Man’s skull differs markedly from the skulls of modern and historic American Indians, which show a clear linkage to Central Asia. Kennewick Man’s cranium, according to Jantz, looks more like the skulls of Polynesians and early natives of Japan.
