The journey we invite you to take this evening is perhaps the most beautiful one. Let's go in search of our most ancient origins. The starting point for our journey is the discovery of a new important hominid that has been added to our family tree. If we had been in Ethiopia about four and a half million years ago, perhaps we might have come across an Ardipithecus ramidus. He is the most ancient ancestor of man; scientists have called him Ardi. She was probably a female and lived in the same region of East Africa where over a million years later another very famous creature of antiquity, Lucy, would roam. Until Ardi's arrival, Lucy's remains were considered the oldest hominid skeleton in our possession. Alberto Angela tells the long history of our species, which starting from very primitive beings led to modern man. An exciting journey in two episodes, a new look at our past, told through what research allows us, albeit incompletely, to reconstruct.
