Topologies supported by analyses of molecular data in the supermatrix. ML/Bayesian tree for all molecular data (A) parsimony tree for all molecular data (B), and ML/Bayesian tree for the nuclear data (C) are shown. Bootstrap scores >50% are above internodes, and Bayesian posterior probabilities >0.50 are below internodes. In B, gray circles at nodes indicate conflicts between the parsimony tree for all molecular data and the ML/Bayesian tree for all molecular data (A). In C, the gray circle indicates the single conflict between the ML/Bayesian tree for nuclear data and the parsimony tree for nuclear data (not shown). The white circles in C mark nodes that are unresolved in the parsimony analysis. Higher-level cetacean taxa are delimited by brackets to the right of the tree in A.
