A walk through time

the long version

Imagine a walk where every step forward transports you a few million years in time. Just such a mind-expanding premise inspired this landmark book, developed from the acclaimed "Walk Through Time" exhibit on tour around the world. Here, in one volume, is the remarkable drama of the history of the universe and life on Earth. Travel from the furious blast of the Big Bang to the first pulse of life, and on through the rich pageant of life's evolution from primordial microbes to the rise of Homo sapiens. Span 15 billion years to discover life's greatest mysteries emerging. Over 130 beautiful four-color illustrations and an absorbing narrative highlight significant events and themes in Earth's life story. The original exhibit itself is re-created as a timeline that runs throughout the book, pinpointing key stages in the evolutionary drama and where they fall in the vast sweep of time.
