Supplementary Table S3, Fit of Bayesian models. Cross-validation estimations of the fit of Bayesian models to the 33 taxa and the three concatenated gene data sets. Models applied to the nucleotide and amino-acid data set are compared to the best fitting ML models, GTRnt + Γ4 and JTT + Γ4, respectively. Models are defined according to their components. Substitution model: GTRnt, GTRaa, MtREV and JTT, exchange rate parameters; CAT, UL2 and UL3, site heterogeneous mixture models. Rates across sites models: + Γ4, discretized gamma rates (Yang 1994, [42]); +COV, covarion model (Tuffley and Steel 1998, [71]).
