Evolutionary history of fishes based on mitochondrial proteins. Phylogenetic tree of 11 fishes and one amphibian using Bayesian analysis of amino acid sequences of 12 concatenated protein-coding mitochondrial genes (omitting ND6). Amphioxus is used as an outgroup. The posterior probabilities are given for each node. The scale bar represents 0.9 substitutions.
