When We First Walked

The video explores the evolution of bipedalism in human ancestors, starting with the discovery of the Laetoli footprints, which challenged the traditional view of human evolution. It discusses the anatomical adaptations for bipedalism, evidence from Australopithecus anamensis and Ardipithecus ramidus, and the potential bipedalism of earlier hominins. Theories on why bipedalism evolved, such as the savannah hypothesis, are examined, highlighting the complexity of this evolutionary transition.
