  1. Note: lnL, the log-likelihood difference between the two models. 2∆l, twice the log-likelihood difference between the two models (P < 0.05 was considered statistically significant). NA means not applicable. M7 means specifies the model of nucleotide substitution (REV); M8 means specifies the model of nucleotide substitution (UNREST)
