When workers digging in a gravel pit near Piltdown, England, in 1912 discovered a collection of bones, the scientific world was turned on its head as the ancient remnants seemed to be the so-called "missing link" between apes and humans. Many scientists heralded the finding as confirmation of Darwin's Theory of Evolution. But it proved to be an astonishingly effective hoax, not a vital clue to mankind's past! Because the bones were so brilliantly doctored, it took 41 years before they were conclusively proven to be the fragments from a human cranium and the jawbone of an ape. Using rare footage and photos, period accounts and expert interviews we tell the fascinating story of Piltdown Man. Relive the incredible uproar the discovery sparked, and examine the many theories about the identity of the con-artist responsible, including Sherlock Holmes's creator Sir Arthur Conan Doyle!
