From Frank & Esther Schierenberg:

Re: Estimates for peopling of Americas getting earlier (March 13): Regarding your article about how humans came to North America and when, it doesn’t discuss racial, nor language root similarities. Esquimos may have come via the Bering land bridge, but not most other natives, many of whom look like the Malays of Malaysia, Indonesia and the Philippines. These are known to have produced some remarkable out-rigger sailing ships and seafarers known to have roamed the Pacific, settling most Pacific Islands in successive waves, including the West coast of America.
