Michael Brandt presents a comprehensive overview of data on population growth during the Stone Age and the quantities of tools found. This reveals significant contradictions to the conventional timeline of human history. These can only be satisfactorily resolved if the entire Stone Age is estimated to have lasted only a few thousand years. The author therefore advocates for a substantial correction of early human history. The research is scientifically grounded, yet the book is also accessible to lay readers. Additionally, the reader gains many interesting insights into the living conditions of Stone Age people.
