Model comparison for analyses relaxing the assumption of autocorrelation of rates across the tree. Harmonic mean model likelihoods were calculated from post-burn-in Markov chain Monte Carlo samples generation in BEAST. For these model comparisons, the topology was fixed as TC. The strict clock model serves as a base comparison. The tree TF refers to analyses where the topology is not fixed. Covariance indicates the degree of substitution rate autocorrelation between ancestor and descendent branches
