| ABSTRACT This article aimed to review various theories of bipedalism and provide a holistic answer to human evolution. There have been two questions regarding bipedalism: i) why were the earliest hominins partially bipedal?, and ii) why did hominins become increasingly bipedal over the time and replaced their less bipedal ancestors? To answer these questions, the prominent theories in the field, such as the savanna-based theory, the postural feeding hypotheses, and the provisioning model, are collectively examined. Because biological evolution is not a simple causation; there may be multiple answers to the evolution of bipedalism. The postural feeding hypothesis (reaching for food/balancing) provides an explanation for the partial bipedalism of the... |
