Likelihood Values, ω Estimates (ω_M2, ω_M3, AND ω_M8), Proportion of Sites with A ω > 1 (ρ_M2, ρ_M3, and ρ_M8) and Number of Positively Selected Sites with a Posterior Probability > 0.95 (n_M2, n_M3, AND n_M8)^a

^aThe comparisons between models M0 and M3, M1 and M2, and M7 and M8 were only significant (p < 0.001) for clade A. ω and p estimates under purifying selection (ω < 1) or neutral selection (ω = 0) are not reported for any model.
