Fig. 7: Comparative analysis of DAN5/P1 occlusal outlines for postcanine teeth.
From: New reconstruction of DAN5 cranium (Gona, Ethiopia) supports complex emergence of Homo erectus
Plots of PC scores derived from the normalized Elliptic Fourier Analyses (EFAs), based on crown contours of a P3 (n = 17), b P4 (n = 17), c M1 (n = 27), d M2 (n = 19), and e M3 (n = 16). Shape differences along PC axes are shown on left teeth, with mesial directed up, two standard deviations from the origin. Points represent individual fossils (Supplementary Table 3). Convex hulls indicate group membership. Colors are as follows: Early Homo = orange and H. erectus = red. Squares differentiate “Sangiran Lower” H. erectus. Specimen abbreviations: prefix K KNM-ER, prefix S Sangiran, KGA Kenyan Gregory Konso, OH Olduvai Hominid, O75-14 Omo 75–14, L894 L894-1, Omo_SH1 Omo SH1-1-17, N2005 Njg 2005.05, SIX Skull IX (Sangiran). The black star represents DAN5/P1. Source data are provided as a Source Data file.
