a, Bivariate plot of the posterior depth of the hyoid body against its height (in mm). The values are logged because the relationship is allometric in modern humans (Supplementary Note S5c). b, Principal components analysis (PCA) of 11 linear morphometric measurements of the scapula of DIK-1-1 (D), G. gorilla (G), P. troglodytes (P) and Homo sapiens (H). Comparative samples include juveniles and adults (Supplementary Note S6i).
