Aportación del ADNa a la reconstrucción históricaLa necrópolis de Aldaieta (Nanclares de Gamboa, Álava) (s. VI-VII)

Resumen

The ancient necropolis of Aldaieta is located North of the lberian Península, close to the city of Vitoria. The importance of this site stems from the fact that Aldaieta belongs to one of the leastknown historical periods in the Basque Country. In this sense, Aldaieta presents a rich cultural assemblage, that shows a clear Frank influence. For these reasons, it seems important to study the bio-social behavior and the genetic affinities of Aldaieta, both with its neighbor populations and with the populations of the rest of Europe. In arder to this, we have ana lyzed the mtDNA variability (SNPs from the coding region and the sequence of segment I of the mitochondrial control region) in the samples recovered at Aldaieta. We have taken into account ali of the safety measures to prevent contaminations and thus, several criteria were met in order to guarantee the authenticity of the obtained results. Among these, the quantification of DNA by Q-PCR, cloning and sequencing of PCR products, analysis in duplicate and replication in a second independent laboratory. The obtained results have allowed us to detect kinship relationships in sorne of the burials as well as the existence of gene flow between Aldaieta and populations of the Cantabrian fringe sorne 5,000-1,500 ya. This work highlights the importance of ancient DNA studies when facing the reconstruction of the evolutionary history of the populations of the past, allowing us to double-check hypotheses obtained from present-day data. lt also represents a useful approach for the study of biosocial aspects of past populations.
