Fig. 1 in Molecular phylogenetics of Mastodon and Tyrannosaurus rex

Fig. 1. Inferred evolutionary relationships of major vertebrate groups hypothesized from collagen al(I) and a2(I) protein data by using a Bayesian approach. The node (bifurcation) labels are measures of support, which indicate the proportion of trees in the posterior distribution to containing the node. Branch lengths are in expected changes per site.
