Extended Data Fig. 6: Tooth size comparisons.
From: Early hominins from Morocco basal to the Homo sapiens lineage
Plots of tooth size measured as centroid size comparing the three ThI-GH specimens (black solid lines) to H. erectus/H. antecessor (left), H. neanderthalensis (middle), and H. sapiens(right). The top row compares the first deciduous molar, second deciduous molar, and first permanent molar, and the bottom row the third mandibular premolar to the third mandibular molar. Shaded areas represent the range for H. erectus (red), H. neanderthalensis (blue) and H. sapiens (green). Fossil H. sapiens are marked separately and individually identfied by accession number. Continuous lines connect the measurements corresponding to different teeth of the same individual. The teeth of the ThI-GH-10978 immature mandible are larger than those of each comparative sample, whereas the permanent postcanine dentition of adult individuals displays smaller third premolars and third molars than H. erectus, and shows a similar pattern of relative tooth size to H. neanderthalensis and H. sapiens.
