The red lines indicate the Procrustes distance between Sts 14 and StW 431. a In modern humans only 35 out of 1353 Procrustes distances (2.6%) exceeded that between Sts 14 and StW 431. b In Pan troglodytes 0% (0 out of 120) distances exceeded that between the fossils, c in Gorilla gorilla 4.5% (6 out of 132), and d in Pongo pygmaeus 3.9% (5 out of 128).
