Phylogenetic relationships of major pancrustacean lineages inferred from concatenated amino acids of 12 mitochondrial protein coding genes (original dataset). Two Chelicerate and three Myriapoda species were used as out-groups. The topology was represented by the result obtained from PhyloBayes under the model of CAT + mtArt. Each group of three numbers at the branch nodes (clockwise) refer to the Bayesian posterior probabilities using PhyloBayes and MrBayes, and bootstrap support values using PHYML. The scale bar represents substitutions per site. '-' indicates the node was not supported by the corresponding analysis.
