Most interesting is this map of haplogroup frequencies, showing that R1b1b2a2c (M153, light blue) is most common among Basques but very rare among other populations (it has also been detected in minimal ammounts in Spain and among Latin Americans), while R1b1b2a2d (M167, dark blue) , while also found among Basques, is much more common among other Pyrenean populations, notably Aranese (c. 50%), being found among other Iberians at small apportions too. This R1b subclade (M167) is known (from other studies) to have been found at rates of 12% among Catalans, 5% among the French (no known data on Gascons, of whom Aranese are a subpopulation), 2% among other Iberians and occasional occurrences in other European locations. I am seriously intrigued about R-M167 frequency among Gascons and Occitans, because the very high apportion among Aranese people and the relatively high presence on all-France samples (as well as NW Iberians) strongly suggests it is rather prevalent through all the prehistoric Franco-Cantabrian region.
Other results refer to haplogroup I. The clade is somewhat common though the Pyrenees and I2a2 (M26, most frequent in Sardinia) appears particularly significative in two locations: "Jacetania" (medieval Aragon county) and Cerdanya (in old Catalonia), with less important presence in other localities and in the rest of Iberia. I(xI2a2) is also somewhat important but it is not clear if it may be I2a1 ("Balcanic"), I2b ("NW mainland European") or I1 ("Scandinavian"). My guess is that, as it mostly associated to I2a2, it will be mostly I2a1 but the matter is not fully clear. Western Basques appear low in both I clades but they are relevant among High Navarrese (Cinco Villas).
The other detached piece of cake is described generically as Neolithic haplogroups. Considering that R1a (very rare anyhow) is assimilated in the R+I cake share as supposedly non-Neolithic, I understand it means haplogroups G, J and E. These ake a significative fraction of the Iberian cake (like 30%) but are less important among Pyrenean peoples (except Alt Urgell). Anyhow, again the study fails to make a distinction between the three haplogroups, that surely had different origins: J arriving from the Eastern Mediterranean, E almost exclusively from North Africa (and surely the most important "Neolithic clade" in Iberia) and G being still an unsolved mystery (though an Eastern Med Neolithic source is likely).
