  • a Normal rate estimated for 1b in this study.

  • b Normal rate estimated for 2a in this study.

  • c Normal rate estimated for 6a in one of our recent studies (26).

  • d Rate prior, normal distribution (mean, standard deviation). Direct rate, rate directly estimated for the data set using the regression approach in Path-O-Gene, shown here only for comparison. Posterior, mean ± standard error of mean (lower, upper 95% confidence intervals). pInv, proportion of invariable nucleotide sites. Uced.mean, mean rate estimated under the uncorrelated exponential molecular clock model. COV, the coefficient of variation, which measures the rate heterogeneity among branches.
