UE2298/MS060 maternal lineage. (a) Phylogenetic tree of mtDNA lineage U6a1a1. ρ and maximum-likelihood (ML) node age estimates (in ka) shown on the branches (in italics and in bold, respectively); sequences are coloured according to geography, with ancient sequences circled in red (position of UE2298/MS060 sequence is indicated by the star); underlined samples are newly reported; mutations relative to rCRS are indicated on the branches. The complete and more detailed tree for haplogroup U6 is shown in Supplementary Fig. S4. Details of the sequences used to build the tree are in Supplementary Table S4. (b) Timeline showing occurrence of haplogroup U6 in the archaeological record of North Africa and Iberia through time2,6,13,14,15,32,33,34,35, and a map of the frequency distribution of U6a in present-day Iberia, with a point indicating the location of Segorbe city. Density maps of additional mtDNA lineages are shown in Supplementary Fig. S5.
