Evolución de la región proximal del fémur y su relación con la bipedestación en los homininos del Plioceno-Pleistoceno

Abstract

Traditionally, the emergence of permanent bipedalism in hominins has been associated with the bipedalism/savanna/hominization model (Cerling 2010 and Domínguez-Rodrigo, 2012). Therefore, the idea that a change in vegetation was the triggering factor for upright posture and locomotion is based on the theoretical principle that all evolutionary change is a direct function of environmental changes. However, the origin of bipedalism and its diversification are two different phenomena.

In light of the fossil record, the proximal region of the femur provides information and evidence regarding the process of bodily hominization (Cartmill and Smith, 2009). This summary therefore synthesizes the emergence and diversification of obligate bipedal locomotion in the hominin genera: Ardipithecus, Australopithecus, Paranthropus, and Homo.
