NOVA and National Geographic present exclusive access to a unique discovery of ancient remains. Located in an almost inaccessible chamber deep in a South African cave, the site required recruiting a special team of experts slender enough to wriggle down a vertical, pitch-dark, seven-inch-wide passage. Most fossil discoveries of human relatives consist of just a handful of bones.
