Ulisse offers his listeners a journey through time to tell the story of prehistoric man who populated Europe in a period ranging from approximately thirty-five thousand to twenty-five thousand years ago, from the Neanderthals to the glaciations. In the first episode, the program retraced the group life, hunting, affections, daily problems of a small tribe of Neanderthals up to the dramatic encounter with Homo Sapiens Sapiens, who migrated to Europe from Africa in that period. A fatal encounter for the Neanderthal, who became extinct within a short time, leaving his territories to this new living species: the species from which we all descend, and which was then to give rise to the great cultures of our history. The story tells a small group of men who lived in a period following the Neanderthals, about ten thousand years later, in the ice age.
