- The estimated parameters from the OU model for fishes were α = 0.050 (phylogenetic half-life of 13.8 my) and σ2 = 0.0001, whereas kappa was estimated to be 3.5 × 10–8 in the insect model. Results shown for diversification rate based on ε = 0.5, see Additional file 1: Table S2 for equivalent model outputs for ε = 0 and ε = 0.9
