Table 6 , 7 , 8 , 9: lnL, the log-likelihood difference between the two models; 2Δl, twice the log-likelihood difference between the two models; The positively selected sites were identified with posterior probability ≥0.9 using Bayes empirical Bayes (BEB) approach. One asterisk indicates posterior probability ≥0.95, and two asterisks indicate posterior probability ≥0.99. NA means not allowed. NS means the sites under positive selection but not reaching the significance level of 0.9.
