Determination genétique de l’individu Néolithique de Segudet (Ordino), les restes humains les plus anciens d’Andorre
Díaz N. et al.
Human remains analyzed in this study come from a prehistoric burial from Segudet, Ordino, Andorra. The skeleton was diagnosed as a female of between 30-35 years of age at death. C14 analysis results in 5350±40 BP; this date and the funerary furnishings found in the burial set it in the ancient Neolithic Age, specifically in the Epicardial period. These are the most ancient human remains found in Andorra. Genetic determination was performed by mitochondrial haplogroup analysis and sequencing the control region. Both analysis enable us to classify this individual within the European haplogroup K. Although population interpretation cannot be carried out, it is interesting to notice the antiquity of this haplogroup in Europe and the strategic location of the country of Andorra as a pass to enter the Iberian Peninsula.
