^a Alternative and null models, see Additional File 8, Table S4 for more information on models and Log-likelihood values, ^b P value calculated from a χ² distribution, ^c number of sites significant in Bayesian post-hoc tests (P < 0.05). The alignment, after deleting gaps, was composed of 364 codons.
