Quantitative State Speciation and Extinction (QuaSSE) analysis for body size dependency on diversification. Linear, Sigmoidal and Modal models were used

Model InL X2 P AIC ΔAIC
Linear −131.16 5.2715 0.0216777 270.32 8.30
Sigmoidal − 128.12 11.3579 0.0099401 268.24 6.22

Sigmoidal (φ) −127.91 11.7817 0.0190503 269.81 7.79
Modal (φ) − 124.91 17.7756 0.0013651 263.82 1.80

The models were run without and then with a directional function (indicated here by phi, φ). P value to test significant difference to a model of constant speciation and extinction. Delta AIC (ΔAIC) calculated by comparing model to the best-fit, lowest AIC, model
