Did you see my post above at #131?
If I recall Jim Chatters said the Kennewick Man most resembled Asiatic ancestary.
If DNA suggests that the American Indians are closer related to peoples of Asia (rather than the Jews), then I would think that the Umatilla Tribe could still lay claim to the Kennewick man.
The DNA analysis on Kennewick Man was officially declared 'undetermined.' Unofficially Chatters gives a 'rough' rundown of the DNA that was obtained and Ainu at 23% was the highest.
Chatters said that there are no American Indian/Native American (as we know them today) skeletons ever found in North America that are older than 6,000 years.
Skeletons like Kennewick Man, Spirit Cave Man, Buhl Woman and etc, belong to another earlier and completely different racial group of people than the American Indians.
9,400 year old Spirit Cave Man was found in a cave in Nevada. He is also the oldest mummy ever found in the Americas. See the resemblance to Kennewick Man.
