*Model comparisons were performed using Likelihood Ratio Test (LRT) between nested models.
Model descriptions: Branch selection models: M0=one class of ω ratio and M0b=tree different ω ratio for the branches. Site selection models (ω ratio varies according to two classes); M8a: beta distribution of ω and ω=1 and M8: beta distribution of ω and ω1 > 1.
