Gene phylogenies. MrBayes GTR/ML phylogenies of Macropus (a) Cyt b, (b) TRSP and (c) concatenated Cyt b + TRSP. MrBayes credibility values are listed below the branches, ML bootstrap values above the branches, and branch lengths are shown in italics. The Cyt b and TRSP trees agree on their placement of M. robustus and M. antilopinus (the wallaroos) as the sister group, though disagree on their placements of W. bicolor, M. giganteus and M. rufus. The concatenated tree reconciles the two divergent trees, placing M. rufus as sister-species to the rest. Distances below 0.008 are not shown, and clade credibility values below 60 are not shown.
