A study confirms the importance of the Cantabrian cornice lineages in the genetic map of Europe
. The study conducted by Dr. Sergio Cardoso Martín confirms the importance of the H1 and V lineages, and also proposes to consider the J1c, U5b and T2b lineages as genetic markers of such an important demographic milestone in the evolutionary history of European human populations.
The most frequent haplogroup in the samples of the Basque Country and Navarra proved to be the H, and more specifically the subhaplogroup H1. In these two populations, the high frequency of the J1c lineage also stood out, and particularly, in the case of northern Navarra, the U5b and T2b lineages also showed notable frequencies. In the valley of Pas, however, the highest frequency corresponded to haplogroup V.
Genetic markers of European recolonization
The study has confirmed the importance of the H1 and V lineages - the most abundant in the sample of analyzed individuals - as genetic markers of postglacial recolonization from the shelters of southwest Europe. Likewise, the study data show that the subhaplogroups T2b, J1c and U5b constitute 'well-preserved paleolithic maternal lineages' up to the present and with relevant frequencies in the area of the Franco-Cantabrian refuge, which is why their inclusion in future dedicated studies is suggested to the search for genetic traces of the postglacial repopulation of Europe and to the evaluation of the impact of this demographic fact on the modeling of the genetic heritage of contemporary European populations.
