But you ddn't point out that it's wrong and that Haplogroup X has been found in Siberia.
And that the Hap X in North American Indians is not the same as found in Europeans.

Kennewick man and the Ainu may well have the same ancestors.

Didn't know either of those. Can you link or lead me to some info to this effect?
