I am not surprised by White Indians in America. I saw that link before. I have seen how Indians are depicted in artwork. They look really big, light skinned, and tall. I would be surprised if American Indians came from Cro-Magnon man. I have read that Navajo language is similar to Basque of Spain and France.
This may explain it?
The Relationship Between The Basque And Ainu
BTW, I was reading the book "Collapse" by Jared Diamond last night and he said that the Vikings of Greenland survived for a while on the ptarmigan bird. Didn't know what it was previously.
