Erratum to ‘Early hominin limb proportions’(Journal of Human Evolution 43 (2002) 529–548)

Abstract

Fig. 9. Schematic diagram of limb proportions in extant taxa (P. troglodytes, far left; H. sapiens, far right) and fossil taxa. Two schematic individuals, representing extremes in our sample, are shown for each extant taxon. Each fossil taxon (and Bouri) is represented by an individual skeleton (it remains to be determined whether or not these specimens are truly representative of their respective taxa): A. afarensis (AL 288-1), H. (A.) habilis (OH 62), Bouri (BOU-VP 12/1), and H. ergaster (KNM-WT 15000). Data on associated limbs are not currently available for A. africanus; in light of studies by McHenry and Berger (1998a, b), A. africanus is provisionally given more apelike limb proportions than those of A. afarensis. Since humerus length, relative to body mass, does not differ among African apes and humans (Jungers, 1994), the schematic representations were given equal humerus lengths. Intermembral and brachial proportions are shown relative to this standardized humerus length. African apes and humans also show little interspecific differences in crural proportions (Aiello and Dean, 1990), so all schematics were given equivalent crural indices, with the exception of H. ergaster, for which crural proportions are known. Trunks, heads, and feet are shown in grey for illustrative purposes only and are not drawn to scale. Lines representing limbs are shown in grey where little or no direct evidence is available.
