Sub-Saharan haplogroup mtDNA L in Spain and Europe

In the study of Rhouda et al. (2006) in a sample of 686 spaniards, not a single individual with haplogroup mtDNA L was found. In the rest of Western Europe, the recent study of García et al. 2011 finds L up to Northern Germany and Denmark . We observe the following percentages  :

Hérault (Languedoc) 2.4 %
Rhône (Lyonnais) 4.4 %
Vendée and Vienne (Poitou) 0.8 %
Calvados and Seine-Maritime (Normandy) 1.8 %
Somme (Picardie) 1.3 %
France Miscellanea 0.6 %
Scotland 0.1 %
England 0.7 %
Great Britain 0.9 %
North-Germany and Denmark 0.7 %

Skin reflectance of selected world populations

From the study of Nina Jablonski and George Chaplin (Academy of Sciences of California).
We can see that Spaniards, from León (NW Spain) and Basques (N Spain), are as light or even lighter than other Western Europeans. Higher values indicate lighter skintone.
