Evolutionary rate of individual landmarks and semilandmarks. a Regression of disparity on evolutionary rate for each landmark and semilandmark, colour-coded by module. The red line is the regression for the entire cranium. The blue line is the Brownian motion prediction, with shaded 95% interval. b-f Landmarks and semilandmarks on the sampled Siphonops annulatus cranium, colour-coded by evolutionary rate from low (purple) to high (red) in (b) dorsal, (c) anterior, (d) ventral, (e) posterior, and (f) lateral aspect. See (Additional file 1: Figure S23) for the pattern of disparity across landmarks and semilandmarks
