Abstract
In the present work, DNA was extracted from 63 skeletal samples recovered at the Neolithic site of San Juan ante Portam Latinam (SJAPL) (Araba, Basque Country). These samples have proved useful as genetic material for the performance of population studies. To achieve this it was necessary to overcome the methodological problems arising when working with damaged DNA molecules. We succeeded in performing an amplification and restriction analysis of the polymorphisms present in the mtDNA. Ninety seven percent of the samples were classified as belonging to one of the nine mtDNA haplogroups described in Caucasians. This work shows that restriction analysis is a useful methodological tool to perform reliable population genetic analysis on archaeological remains. Tha analysis of ancient and modern haplogroup distribution can shed more light on the genetic evolution of human populations. Moreover, a more exhaustive data on prehistoric populations will allow to build stronger hypothesis on the genetic relationships among human populations.
