Abstract

One of the most important discoveries in hominoid evolutionary studies is the fossil forelimb of Proconsul africanus (KNM-RU 2036), discovered in 1951 from the early Miocene deposits of Rusinga Island, Kenya. Napier and Davis (1959, p. 1) describe the importance of the fossil:

The discovery of the fore-limb bones of P. africanus is therefore an event of considerable moment, for they constitute the oldest and most complete skeleton of the hominoid fore-limb so far known. It is clear that these bones belong to one of the most significant periods of primate evolution; a period when the generalized catarrhine stock was emerging from a prolonged phase of arboreal quadrupedalism with its limited opportunities for adaptive radiation and was entering upon a phase that would provide a diversity of environmental opportunity leading ultimately to the emergence of four distinct patterns of locomotion among the Anthropoidea: (1) arboreal quadrupedalism, (2) terrestrial quadrupedalism, (3) brachiation, (4) terrestrial bipedalism.
