Has a 4.4-million-year-old: missing link, been found? The groundbreaking discovery of the skeleton nicknamed: Ardi, more than a million years older than Lucy, offers a fascinating look at what the last common ancestor of humans and living apes might have been like. An international team of scientists, who 17 years ago began an investigation of the remote Ethiopian desert where the discovery was made, has painstakingly analyzed its findings and now can reveal in compelling detail how and why humans emerged. This exclusive peek at a new chapter on human evolution, narrated by Dirty Jobs’ Mike Rowe and illuminated with 3D recreations, brings Ardi and her world to vivid life.
