Lucy's discovery in eastern Africa reshaped human origins research, highlighting our ancestors' diverse habitats. Initially thought vegetarians like chimpanzees, Lucy's group were adaptable omnivores. Recent findings suggest they used tools and hunted, challenging notions of early human development. This raises questions about when humanity's defining traits emerged. Did Lucy's dietary flexibility pave the way for our intelligence and tool use? Ongoing research aims to unravel these mysteries, using innovative methods to understand ancient diets and behaviors.
