My view is closer to that of Zelto, although Kristina does make some interesting points. I think it is really telling that there is virtually no Haplogroup N among Native American populations (with the exception of the Tlicho, a Na-Dene speaking indigenous group in Northern Canada. The Na-Dene peoples are in fact descended from a later migration into the New World than most indigenous Americans.
Wow, AFAIK all Y-chromosomes in NAms known so far fall under C and Q, do you have a reference??
