Abstract:
:This paper describes the development of a knuckle walking mode of locomotion by a free-living yellow baboon (Papio cynocephalus). Some implications of this occurrence for theories of the evolution of knuckle walking are discussed.

杂志文章abstract::Inferred dietary preference is a major component of paleoecologies of extinct primates. Molar occlusal shape correlates with diet in living mammals, so teeth are a potentially useful structure from which to reconstruct diet in extinct taxa.
