This form of locomotion is primarily associated with humans and certain other primates, but some birds, like ostriches and emus, are also bipedal. The evolutionary development of bipedalism in hominins is a significant topic in anthropology, with various theories explaining its advantages, such as freeing up the hands for tool use, improved efficiency in long-distance travel, and better thermoregulation.
The skeletal structure of bipedal animals is adapted for upright posture and locomotion. This typically includes
