Figure 1.

Average event-pair scores (EPSs) plotted on a phylogeny of the taxa examined, with visual examples of forelimb (FL) and hindlimb (HL) across the tree. Plot symbols in blue and green are significantly less than and greater than one, respectively; forelimb-hindlimb synchrony, in red. The tree is derived from references 33 and 34.
