Bayesian maximum clade credibility phylogenomic tree derived from mitochondrial genome sequences (16,435 base pairs) of 22 baleen whales. Kogia breviceps (Odontoceti; Kogiidae) was used as an outgroup. The data set was also phylogenetically analyzed with BI, ML, and NJ methods and identical topology was produced. Node bars correspond to the 95% HPD for TMRCA of nodes and the numbers on the nodes represent (left to right): posterior probabilities (≥0.80) for Bayesian inference tree, bootstrap values (≥70%) for maximum likelihood tree, and bootstrap values (≥70%) for neighbor joining tree. The scale bar represents time in million years before present (MYBP).
