seattle times had an article a couple years ago on the possible polynesian skull found in california ...but also remember that the voyage of the kon tiki showed it was possible that there was also migration from south america into the pacific islands as well as from the west..and that people also could have sailed from africa to south america....

also...when they say kennewick man was 'caucasian' they don't mean in the 'viking' sense but more like the Ainu of northern japan...
