Bipedal movement refers to the ability to walk on two legs, a characteristic feature of humans and some other animals. This form of locomotion allows for greater energy efficiency and the ability to cover long distances. Bipedalism is made possible by the unique structure of the human skeleton, including the pelvis, spine, and lower limbs, which are adapted for upright walking. The evolution of bipedal movement is significant in the study of anthropology and paleontology. It is believed to have provided early humans with advantages such as improved visibility over tall grass and the ability to carry objects while moving. Bipedalism also plays a crucial role in the development of tool use and social interaction.
