HiSSE model selection comparing absent and present (rudimentary and developed) dewlaps and parameter estimate results, including log-likelihoods, AIC, difference in AIC with minimum value (ΔAIC) and parameter estimates for speciation rate dewlap absent (λ0), dewlap present (λ1) and with hidden states (λA and λB). Other parameter estimates are not shown as they were not relevant to the goals of this study.
