Note: * refers to P < 0.05. ** refers to P < 0.01; (1): M1a versus M0, (2): M2a versus M1a, (3): M8 versus M7 (4): M8 versus M8a. The proportions of sites under positive selection and selective constraint are p1 and p0 respectively. The parameters p and q are used for the beta distribution B(p, q).
