From: Evolutionary development of the Homo antecessor scapulae (Gran Dolina site, Atapuerca) suggests a modern-like development for Lower Pleistocene Homo

Figure 1

Centroid size analysis for the current and fossil specimens, showing 95% confidence intervals for the mean of each species and group. Numbers along the x-axis refer to the ontogenetic stage in Pan and Homo (green = Pan; red = Homo) and fossil scapulae are inserted. The DIK-1-1 interval is based on its right and left scapula; other fossil CI are based on particular estimates from previous analyses. DIK-1-1 is stage 2, based on its fully erupted deciduous dentition (no permanent teeth). KNM-WT 15000 is between stages 4 and 5, based on its fully erupted 2nd molar. MH2 is a small adult female, based on long bones lacking an unfused epiphysis65. The Gran Dolina fossils are not associated with dental remains, and so their ontogenetic stage can only be estimated by their relative size.
