They were the first. I believe there were others.
The geneticist’s study says there are only 70 separate DNA strains in the bloodlines of all AMerinds.
If some folks can believe that everyone is descended from only two people, I don’t see why a scientific finding of 70 DNA lines in N. America isn’t possible.
Agreed... some of the East Coast indians suggest European ancestory. The Cherokee language is actually very similar to Greek and some ancient Hebrew artifacts have been found in obscure places like Oklahoma... I do believe some Asiana came across the land bridge as suggested, but do not believe Lied Ericson was the next to make it here.
