Phylogeny of Metazoa inferred from the concatenation of the 13 mitochondrial proteins. Bayesian consensus tree of 5 individual MCMC obtained using the CAT+BP+Γ4 mixture model on the concatenation of the 13 proteins (54 taxa and 2,136 amino-acid sites). Values at nodes indicate Bayesian posterior probabilities (PP). Circles indicate strongly supported nodes with PP ≥ 0.95. The scale bar represents the estimated number of substitutions per site.
