This ebook edition does not include illustrations. A magisterial exploration of the natural history of the first four thousand million years of life on and in the earth, by one of Britain's most dazzling science writers. What do any of us know about the history of our planet before the arrival of man? Most of us have a dim impression of a swirling mass of dust solidifying to form a volcanic globe, briefly populated by dinosaurs, then by woolly mammoths and finally by our own hairy ancestors. This book, aimed at the curious and intelligent but perhaps mildly uninformed reader, brilliantly dispels such lingering notions forever. At the end of the book we understand the complexity of the history of life on earth, and the complexity of how it has come to be understood, as, perhaps, from no other single volume. The result is enthralling. Note that it has not been possible to include the same picture content that appeared in the original print version.
