Influence of phylogeny and allometry across the ten cranial modules. Network graphs from EMMLi analysis of the ten-module model. Modules are graded low (yellow) to high (red) based on (a) phylogenetic signal (Kmult) and (b) evolutionary allometry (R2). Circle size is proportional to internal trait correlation; line thickness is proportional to between-module trait correlation. Layout corresponds approximately to a cranium in right lateral view. See Fig. 1 for module definitions
