Fig. 1From: Radiating pain: venom has contributed to the diversification of the largest radiations of vertebrate and invertebrate animalsVenomous families have a net diversification rate approximately double that of non-venomous families for both fishes and insects. Diversification rates and standard errors are based on estimated parameters from a model accounting for clade age which found that the differences shown here are statistically significant despite the relatively wide confidence intervals (Table 2)Back to article page
