Model comparison results.

Listed are the model ID, type of two-epoch model (TEM) and clock model, transition time (TT, 10−3 mutations/site), median marginal likelihood (MML), and 2×log Bayes factors (2×lnBF) for the models. Parameters for the best-fit model are shown in bold type. The result for the exponential TEM with strict clock is not shown because the run did not converged.
