Disparity-through-time (DTT) plots for PCa1 (blue line), PCb1(green line), body size (red line) and HWI (grey line). Disparity along the y-axis is the average subclade disparity divided by total clade disparity and is calculated at each internal node of the tree. The dotted lines represent values of trait disparity expected under BM by simulating trait evolution 2500 times each across the tree. The shaded area denotes the 95% range of the simulated data. For relative time values 0 represents the root and 1 the tip of the phylogeny. MDI values along the range of p-values computed by means of the rank envelope test [73] are given
