Figure 5. Time-calibrated phylogeny of spiders with branches colored by reconstructed net diversification rates (A).

Rates on branches are means of the marginal densities of branch-specific rates. Inset histogram shows posterior density of speciation rates. Smaller phylogenies (B) show the four distinct shift configurations with the highest posterior probability. For each distinct shift configuration, the locations of rate shifts are shown as red (rate increases) and blue (rate decreases) circles, with circle size proportional to the marginal probability of the shift. The macroevolutionary cohort analysis (C) displays the pairwise probability that any two species share a common macroevolutionary rate dynamic. Dashed arrow indicates position of RTA clade on each tree.
