Figure 4 in Adaptation to graviportality in Rhinocerotoidea? An investigation through the long bone shape variation in their hindlimb

Figure 4. Results of the PCA performed on morphometric data of the complete femur and shape variation associated with the first axis of the PCA (cranial view). Blue: negative side of the axis. Orange: positive side of the axis. Phylogenetic relationships are plotted in the morphospace. Colour codes follow Figure 1 and abbreviations follow Table 1. Point size is proportional to the mean log centroid size of each species.
