Title: Optional

Text: Three important revolutions shaped the course of history: the Cognitive Revolution kick-started history about 70,000 years ago. The agricultural Revolution sped it up about 12,000 years ago. The Scientific Revolution, which got under way only 500 years ago, may well end history and start something completely different. This book tells the story of how these three revolutions have affected humans and their fellow organisms. Each paragraph will be a test.
