Phylogeny based on 24 mitochondrial/bacterial proteins (6,542 amino acid positions) inferred by Bayesian Inference with the GTR + F (left) or the CAT mixture (right) model on the Dayhoff recoded dataset.

<p>(see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030520#s3" target="_blank">Methods</a> for details). Branches without values are supported by posterior probabilities of 1.0. The scale bar denotes the estimated number of amino acid substitution per site. See supplementary material for complete species names and proteins used.
