Linear regression between divergence time and evolutionary rate parameters. Data obtained from MCT trees under different tree model, clock model, and sampling strategies with a single morphological clock partition. a–c Precision around individual node divergence time estimates, based on 95% highest posterior density (HPD) ranges against median divergence times. d–f Median relative evolutionary rates against median divergence times. g–i Precision around individual node relative evolutionary rate estimates, based on 95% HPD ranges against median divergence times.
