Parsimonious reconstruction of the amino acid changes along the phylogeny of cytochrome b in talpids. Present state of the amino acids and codons in position 329 of the cytochrome b protein is shown in blue color for several talpid species, including Desmana and Galemys. Deduced ancestral amino acid states are shown for each node in blue color. The two non-synonymous changes deduced in this position are represented by a vertical bar in the corresponding branches. For every change, the codon and amino acid changes are shown. The change shared by G. pyrenaicus lineages A1 and A2 is shown in red color.
