Bipedalism Theories

Bipedalism theories explore why humans evolved to walk upright on two legs. Some suggest it helped early humans see over tall grass or spot predators, improving survival. Others believe walking upright freed the hands for tool use and carrying objects. Climate changes may have made forests sparse, encouraging movement on open ground. It might also have helped regulate body temperature by reducing sun exposure. Most theories agree that a combination of these factors influenced our ancestors to adopt efficient two-legged walking, which is a key step in human evolution.
