[close] "The excitement of discovery cannot be bought, or faked, or learned from books," London Natural History Museum senior paleontologist Richard Fortey writes in Life. The first chapter, an engrossing account of an Arctic fossil-hunting expedition he undertook as a university student, will bring shivers to anyone who has ever ignored cold hands, hunger, and filthy socks to keep looking for something new, some piece of rock or bit of plant that may hold the key to the gleaming certainty of understanding. Fortey's descriptions of scruffy field assistants and eccentrically brilliant scientists are easily as interesting as the billions of years of evolution he so imaginatively describes. After all, the fossil record has not been accepted without controversy, and the arguments among fallible evolutionary biologists as they refined their theories make for great reading. But it is the little animals that make up our distant ancestry that are the focus here. The often mysterious fossils they left behind are like a history book in a language we don't know--the history of bugs and birds, humans and cauliflowers. One by one, Fortey reveals how the puzzles of paleontology have been subjected to the scientific method and to the politics and personal ambitions of academia, until a beautifully clear path is traced from the very first traces of life all the way across the eons to the advent of Homo sapiens. Fortey's elegantly written tour lets us share his passion for ancient seas and the animals that frolicked in them, and understand how time and chance contributed to the biography of us all. --Therese Littleton [close]
