Collection localities for the house mice used in this study and the phylogenetic tree based on their mtDNA sequences and additional published material (see Methods section). Our new collection localities are shown as triangles (ancient specimens) or circles (modern specimens) and are coloured according to the mtDNA clade affinity, with the clade name printed in the same colour next to the clade; previously published haplotype distribution (approximate) is shaded. Location numbers on the map correspond to those used in Table 1. New haplotypes are indicated on the tree as squares and labelled according to their location (NF = Newfoundland, GL = Greenland, IC = Iceland). Posterior probabilities of 0.7 or above are shown for the branches leading to haplotypes found in this study. Ancient, mostly Viking Age, haplotypes are shown in bold (aIC = ancient Iceland, aGL = ancient Greenland). The Viking Age site in Newfoundland is marked with *. The M. m. musculus/M. m. domesticus hybrid zone is marked with a thick dashed black line.
