Fig. 4: Centroid size of the distal humeral transverse (~19%) section.
From: Early evolution of small body size in Homo floresiensis
Symbols: circle = australopith; square = Homo; black = adult (possibly including some late adolescents); white = subadult. The specimens in each morphological group are listed in Supplementary Data 3 along with their size values. A standard box plot (the median at horizontal line and the ‘whiskers’ representing minimum/maximum values) is shown for a sample (N = 21) of modern humans. Transverse dashed line for Group 2 connects specimens belonging to Au. sediba and Au. sp. indet. Vertical dashed lines represent the smallest (proximal section) and largest (distal section) values obtained for SOA-MM9, which is smaller than all adult Plio-Pleistocene fossil hominin humeri (including LB1) and similar in size to specimens of H. naledi. Note that fully adult status (proximal epiphyseal fusion or developed muscle markings on the shaft) cannot be confirmed for some specimens such as the smallest individuals of Group 1b (SKX 10924) and Group 4 (SK 2598 and SK 24600). See Supplementary Data 3 for other notes.
