Phylogenetic relationships of frogs inferred from the 91-species data set (11,007 characters, excluding third codon positions). Only part of the tree is shown (Ranoidea) because the deeper branches (archaeobatrachians, hyloids, etc.) are identical in topology and support to those in figure 3. The data set was analyzed with partitioned maximum-likelihood and Bayesian methods. At each node, the shading of the upper rectangle indicates the bootstrap value for the ML analyses; the shading of the lower rectangle indicates the Bayesian posterior probability. Nodes lacking support boxes have >95% support for both bootstrap proportions and Bayesian posterior probabilities. Branch lengths were estimated by the Bayesian analysis. The shaded gray circle indicates the node Microhylidae + Brevicipitoidae that is recovered in other analyses (compare with fig. 3). See supplementary fig. S2, Supplementary Material online, for complete tree in color.
