Fig. 6: Tooth size apportionment (TSA) analysis for size-corrected MD and BL crown dimensions of P3-M3 (n = 12).

a Ordination of PC 1 and PC 2 of size corrected MD and BL dimensions for P3‒M3 (TSA). Description of changes along each PC are based on PC loadings ≥ |0.6|. b Visual representation of loadings in this PC subspace at the position corresponding to DAN5/P1. White lines represent negative loadings (relatively smaller dimensions) and black lines represent positive loadings (relatively larger dimensions), with thickness corresponding to strength of the loading. c Occlusal views of left postcanine teeth in DAN5/P1 to scale (adherent bone masked in M1 photograph). Convex hulls indicate group membership. Colors are as follows: Early Homo = orange, H. erectus = red, H. naledi = brown. A square differentiates “Sangiran Lower” H. erectus. The black star represents DAN5/P1. Small symbols represent individual fossils. Specimen abbreviations: S4 Sangiran IV, L894 L894-1. Large symbols are group averages for early African H. erectus (EAf_erec), “Sangiran Upper” H. erectus (USang_erec), and H. naledi (H_nal) (Supplementary Table 3 and Supplementary Data 1).
