The Ape Ecological Niche: Posture and Hand Use in Gibbons and Macaques and the Influence of Manual Skill on Cognitive Development in Apes and Humans
… This study examines the general model that orthogrady and suspensory postures were the antecedents for enhanced manipulative ability in apes, which consequently set the stage for enhanced cognitive abilities in early hominoids. The primary hypothesis is that if single-handed prehensility is …

Functional morphology of mammalian sacra and caudal vertebrae : implications for tail loss and positional behaviors in extinct primates
… to face difficulty identifying taillessness and orthogrady from fossil material. In part, difficulties persist because although the Miocene fossil record indicates that the evolution of tail loss and orthogrady was decoupled, previous research has focused primarily on how the skeletal anatomy of …
