Fig. 3: PCA plots of great apes, H. sapiens, and fossil hominins.

PCA plots showing PC1 vs. PC2 (on the left) and PC1 vs. PC3 (on the right). Each group’s mean is shown together with individual fossil hominins (see SI Fig. S3 for comparison). Navicular shape differences along the first three PCs are represented by the respective renderings in proximal (top left), distal (top right), and plantar (bottom) views.
