Less than 50,000 years ago mankind had no art, no religion, no sophisticated symbolism, no innovative thinking. Then, in a dramatic and electrifying change, described by scientists as "the greatest riddle in human history," all the skills and qualities that we value most highly in ourselves appeared already fully formed, as though bestowed on us by hidden powers. In Supernatural Graham Hancock sets out to investigate this mysterious "before-and-after moment" and to discover the truth about the influences that gave birth to the modern human mind.
