  1. Abbreviations: λ – speciation rate, μ - extinction rate, q – transition rate, lnLik – logarithm of likelihood, AIC – Akaike information criterion. The best scoring model is indicated with bold italics (parameter estimates presented in Table 3); three models with AIC scores within 2 of the best scoring model are indicated in bold (parameter estimates presented in Additional file 4: Table S2)
