Extended Data Fig. 10: Mean (sd) correlation coefficients (Pearson’s r) for the realised relationship between simulated rates of speciation and trait evolution.

Realised rates of trait evolution are inferred by calculating the squared-trait distance between known simulated ancestral and descendent nodes in the tree, divided by phylogenetic branch length (that is time). Note: Pearson’s r values in the table header refer to the correlation strength between speciation and trait rates used in the stochastic model used to generate trait values. n = 100 trees in each case.
