OverfitRR analysis of search.shift results, with 100 ancestral state estimation regression simulations. For each clade, values for p.shift+ and p.shift– are the percentage of simulations that obtained statistically significant (P‐value < 0.05) positive or negative evolutionary rate shifts. “All clades” reports results assuming all nodes evolved under a single rate
