Morphological variations and asymmetry

A study of the conarticular surfaces in the reconstructed wrist of Dryopithecus (Proconsul) africanus reveals that they most probably attained their close-packed and habitual position when its hand was dorsiflexed as it occurs in the palmigrade quadrupedal stance and locomotion of Alouatta and Ateles . This report, therefore, denies knuckle-walking as a possible locomotive habitus for D. (Proconsul) africanus , and proposes Alouatta and Ateles as the best available models for the locomotor behavior of D. (Proconsul) africanus .
