abstract
For comparison with previously defined relative long bone lengths of growing anthropoid apes, the relative size increase of the raduus/humerus, tibia/femur and leg/arm lengths for Homo sapiens were determined. Results indicate that Homo follows other Hominoidea during postnatal growth, maintaining general isometric patterns of relative long bone size increase within the proximal and distal segments of each limb. Variation between genera is primarily proportional, with Homo showing the relatively shortest radii and shorter tibae throughout growth. Between limbs Homo displays specializations toward disproportional increases of the lower limb, suggesting size required allometry for facilitative support. 1982 Japan Monkey Centre.
