Fig. 5: EDJ shape variation in maxillary first molars.

a PCA plot of M1 EDJ shape. Homo habilis specimens are represented by green points. Aus = Australopithecus. PC = principal component. b Wireframe images showing shape changes associated with the first principal component, showing landmark positions associated with extremes of PC1 (±1.5 standard deviations from the mean) in occlusal view (top) and lingual view (bottom). c Frequency plot of Procrustes distances between all possible pairs of individuals within (coloured lines) and between groups (grey fill). Vertical lines show the 95% limits of the within-group distributions. Below is shown the Procrustes distances between OH 16 and other H. habilis or early Homo specimens. Green = Pan troglodytes, Purple = Homo sapiens. H. sap = H. sapiens. d Same as c for dentine body height. Source data are provided as a Source Data file.
