Median joining network of Biarzo shelter mtDNA results integrated with previously reported ancient and modern data.
Data obtained in this study are shown in different colours (related also to Fig. 3), data from other studies10,11 are in grey; haplotype frequencies were indicated only for the samples from Biarzo shelter. The coloured squares below the haplotype names indicate the stratigraphic layers and the number of individuals in which each haplotype was found (colours according to Fig. 1). Association between the haplotypes and their putative geographic origin as inferred in10 was also indicated.
