LnL = Likelihood values; ω = estimate of dN/dS (ωM2 and ωM8); p = proportion of sites under diversifying selection (pM2 and pM8); PSS = number of positively selected sites with a posterior probability > 0.95 (PSSM2 and PSSM8). All comparisons between nested models (M1 vs M2, and M7 vs M8) were significant.
