Maximum likelihood phylogenetic tree showing the relationship between 41 samples of blind mole rats plus one outgroup <i>Acomys cahirinus</i>.

<p>Numerical values represent bootstrap values out of 1000 reiterations. The nodes marked by capital letters represent internal and external branches supported by bootstrap values higher than 95%. The clades are referred to by Roman numerals: I “Spalax”, II “vasvarii”, III “leucodon”, IV “xanthodon” and V “ehrenbergi” (a). Taxonomic nomenclature is according to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030043#pone.0030043.s001" target="_blank">Table S1</a>; Neighbour-net graph showing an agreement in the major splits with the ML tree (b).
