Extended Data Fig. 8 in A new species of Homo from the Late Pleistocene of the Philippines

Extended Data Fig. 8 | CCH4, proximal pedal phalanx of H. luzonensis. a, Photograph of the original specimen CCH4 in lateral view. b, Threedimensional rendering of CCH4. From left to right: plantar, lateral, dorsal, medial, distal (top), proximal (bottom), disto-lateral and proximo-lateral aspects. c, Comparison of CCH4 with Pliocene (A.L.333-115h, left third proximal phalanx, mirrored), Pleistocene (LB1/36, unknown side and rays 2–5) and recent ('Negrito' 9764, right third proximal pedal phalanx), proximal pedal phalanges in plantar (top) and side (bottom) views. d, Transverse (1, 2, 3) and mid-sagittal (4) micro-CT slices of CCH4 (plantar aspect of three-dimensional rendering, during the segmentation process; 1, 2, 3, dorsal is up, plantar is down, lateral is left, medial is right; 4, distal is up, proximal is down, dorsal is left, plantar is right). e, Protocol for three-dimensional Procrustes analysis: landmarks placed on the main anatomical features (n = 20, in red) and equally spaced semilandmarks (n = 250, in green) placed on the whole surface of the proximal pedal phalanx (template shown on the proximal pedal phalanx, ray 2 of the right foot of the recent H. sapiens 35071). f, g, Box-and-whisker plots depicting comparisons of the articular angle a (f) and the dorsal canting angle α (g) of the proximal pedal phalanx CCH4. Box, 25–75th percentiles; centre line, median; whiskers, non-outlier range; dots, outliers; dotted line, value for CCH4. A detailed list of specimens can be found in Supplementary Table 11.
