Ancient mitochondrial DNA from the Basque Country and Cantabria

This seems a very important paper because, if everything is correct, it is the first peer-reviewed publication to establish conclusively that mitochondrial haplogroup H, the most common matrilineage of Europe today, existed in Paleolithic populations in Europe, specifically in Cantabria, Spain.

There have been previous reports of such important presence of mtDNA H in the area, notably Chandler 2005 (on Epipaleolithic and Neolithic Portuguese) and Kéfi 2005 (on Upper Paleolithic Moroccans). However both studies were informal for some reason, what has been used by some to grasp for straws in their claim of this lineage having arrived to Europe (and North Africa) only after Neolithic and oversimplify the Paleolithic genetic pool of Europe to almost only variants of haplogroup U (never mind that U is such a large, ancient and widespread haplogroup that saying "U" is almost like saying nothing).
