Table 4. Measures of phylogenetic signal (estimated as K values) for venom and diet variation across the 8 taxa shown in Fig. 1.
| Trait - venom | K-value | P-value |
| DISI | 0.052 | 0.70 |
| LAO | 0.26 | 0.06 |
| CRISP | 0.04 | 0.83 |
| PLA2 | 0.08 | 0.37 |
| SP | 0.07 | 0.50 |
| SVMP | 0.11 | 0.37 |
| PEP | 0.15 | 0.20 |
| PC 1 - venom | 0.09 | 0.37 |
| PC 2 - venom | 0.12 | 0.23 |
| Trait - diet | ||
| % mam | 0.16 | 0.11 |
| % liz | 0.08 | 0.44 |
| PC 1 - diet | 0.11 | 0.22 |
P-value represents the probably that the observed value is greater then the expected value if trait values were randomly assigned to tip taxa. Trait names are as in Table 3 with the exception that PC 1 and 2– venom are the PC scores for composite venom variable and PC 1– diet are PC 1 scores for the composite diet variable. For venom, PC 1 and 2 explained 49% and 31% of total variation respectively, and had the following variable loadings (PC1 - DISI (−0.11); LAO (−0.36); CRISP (0.41); PLA2 (−0.88); SP (−0.12); SVMP (0.92); PEP (−0.42); PC2 - DISI (0.23); LAO (0.87); CRISP (0.64); PLA2 (−0.44); SP (0.72); SVMP (−0.33); PEP (0.12). For diet, PC 1 explained 87% of total variation and had the following loadings (% mammals (−0.95); % lizards (0.91).
