From: Activity of two key toxin groups in Australian elapid venoms show a strong correlation to phylogeny but not to diet

Testing for accelerated evolution of PLA2 and LAAO, and for correlation with diet, based on phylogenetic comparative methods in BayesTraits. (Upper) The delta parameter estimates for PLA2 and LAAO: values <1 indicate faster initial rates of change. We have included an adjusted PLA2 profile (alternative species) with venom values for Denisonia maculata and Austrelaps ramsayi substituted for their sister-species, which changes our delta value from 0.64 to 0.9. (Middle and Lower) Regression coefficients (beta) values for PLA2 and LAAO when phylogenetically regressed against the proportions of eight dietary items. A beta of 0 indicates no correlation
