Survival expert Cat Bigney and Archaeologist Bill Schindler survive the wild savanna just as primitive people did 2.6 million years ago.

Cat Bigney and Bill Schindler journey into the jungles of Uganda to follow in the footsteps of one our earliest ancestors — Homo erectus.

Archaeologist Bill Schindler and survival instructor Cat Bigney follow in the footsteps of where Homo sapiens first walked the Earth, through the mountains of Ethiopia. This is where humans became the dominant species, by going from hunted to hunter. Schindler and Bigney attempt to hunt using the methods of our earliest ancestors. After little success in the lowland prairie, they move into the higher elevations, where the thin air and thick fog present unforeseen challenges.
