  1. aAlternative and null models, see Additional File 2, Table S1 for more information on models and Log-likelihood values, bP value calculated from a χ2distribution, cnumber of sites significant in Bayesian post-hoc tests (P < 0.05), dclade consisting of all species excluding Drosophila. The alignment, after deleting gaps, was composed of 298 codons. Tests that we deemed weakly significant because Bayesian post-hoc tests did not detect relevant AA are shown in italics.
