Less than 50,000 years ago mankind had no art, no religion, no sophisticated symbolism. Then, in a dramatic change, all the skills and qualities appeared already fully formed. This work 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.
