Patterns of morphological, dietary and genetical divergence through time. (A) Scatterplot between shape distances (Procrustes) between pairs of species and genetic distances (percent sequence divergence [33]) for the same pairs. (B) Scatterplot between shape distances (Procrustes) between pairs of species and time since divergence. (C) Line plot showing changes in relative morphological disparity through time (DTT). Relative morphological disparity measured as average squared Euclidean distances (with the full set of shape PCs) among existing clades at a given point in relative time. The blue solid line shows the observed disparity, and the red dashed line shows the expected disparity under a neutral evolution model as the average of 1000 simulations. (D) Same as C, but showing changes in relative size disparity through time. (E) Same as C, but showing changes in relative dietary disparity through time. Relative dietary disparity measured as average Manhattan distances using relative importance of diet items for each species.
