From the article:

Their results show that the haplogroup called D4h3 spread from Beringia into the Americas along the Pacific coastal route, rapidly reaching Tierra del Fuego. The other haplogroup, X2a, spread at about the same time through the ice-free corridor between the Laurentide and Cordilleran Ice Sheets and remained restricted to North America.

To this I think we can add haplotype A01 as one of the founding groups associated with the early migration along the Pacific coast.

Now that you mention it, I think this may be a duplicate topic... uh boy (hustles off into the vast intricacy that is FR)...

oh, okay (whew), I guess not.
