In this first episode Zeinab Badawi travels across the continent, examining the origins of humankind and how and why it evolved in Africa. During her journey Zeinab is granted rare access to the genuine bones of one of the most iconic discoveries in the field of archaeology: Lucy in Ethiopia, the oldest hominin ever discovered. Zeinab also spends time with a unique tribe in Tanzania, who provide insight into how we have lived, for most of our history, as hunter-gatherers. She also looks at what distinguishes us from the animal world and makes us human.
