Extended Data Fig. 2 in A new species of Homo from the Late Pleistocene of the Philippines

Extended Data Fig. 2 | Dental metrics. a, b, d–f, Bivariate scatter plots for mesio-distal (MD) versus bucco-lingual (BL) diameters of P3 (a), P4 (b), M1 (d), M2 (e) and M3 (f). c, Key for a, b, d–g, j, k. Sample sizes for a, b, d, e, f, respectively: Australopithecus, n = 23, 23, 21, 26, 26; Paranthropus, n = 22, 20, 26, 23, 20; African and European early Homo, n = 23, 19, 37, 21, 17; Asian early Homo, n = 16, 17, 17, 13, 11; H. neanderthalensis, n = 23, 26, 27, 30, 20; H. sapiens, n = 57, 61, 86, 70, 33; H. floresiensis, n = 1, 1, 1, 1, 0; H. luzonensis, n = 2∗, 2∗, 1, 1, 2 (∗CCH8 is a P3 or a P4). A detailed list of specimens can be found in Supplementary Table 4. g–i, bgPCA of the log-shape ratios of bucco-lingual and mesio-distal diameters of four postcanine maxillary teeth (P3, P4, M1 and M2), CCH6 was treated as a supplementary individual and was plotted a posteriori. g, Scatter plot of specimens for bgPC1 versus bgPC2, with convex hulls for all groups, except H. floresiensis and H. luzonensis. Sample sizes: Australopithecus, n = 6; Paranthropus, n = 5; African and European early Homo, n = 13; Asian early Homo, n = 5; H. neanderthalensis, n = 12; H. sapiens, n = 47; H. floresiensis, n = 1; H. luzonensis, n = 1. A detailed list of specimens can be found in Supplementary Table 4. h, Variable scores for bgPC1 versus bgPC2 (correlation circle; log-shape ratios of variables). i, Bar plot of eigenvalues (%) of bgPC1–bgPC5. j, k, Bivariate scatter plot of the summed square root of computed occlusal surface areas of premolars versus molars (j) and bgPCA of the log-shape ratios of buccolingual and mesio-distal diameters of four postcanine maxillary teeth (k) similar to the analyses presented in Fig. 3b and in g, respectively, but with 'Negritos' treated as a separate group (same sample sizes as in g, except for: H. sapiens, n = 38 and H. sapiens 'Negritos', n = 9).
