"The face of the earth, crisscrossed by chains of mountains like the scars of old wounds, has changed and changed again over billions of years, and the testament of the remote past is all around us. In this book Richard Fortey teaches us how to read its character, laying out the dominions of the world before us. He shows how human culture and natural history - even the shape of cities - are rooted in this deep geological past."--BOOK JACKET.
