Summary: a decent book on human prehistory
Review: Tudge has an interesting book with "The Time Before History." He spends a great deal of the book laying the groundwork for the appearence of the ancestors of humans, with detailed discussions of geology, climate, and the evolution of fauna and flora. The chapter on prehistoric creatures was pretty interesting, and considering the dearth of popular works on extinct mammals make this book a worthwhile read alone. Tudge though is at his best when describing the various types of early humans and protohumans -from the various types of Australopithecines to Homo sapiens - and how they evolved, how they lived, and in some cases, how they spread. Useful are his discussion of ecomorphs and how the generalized ecomorphs of primates favored the development of bipedal, tool-using, intelligent protohumans, and his coverage of the diet of australopithecines and early humans and how this affected our evolution, as well as what we know of these beings. Tudge also provides a lot of interesting theories and information regarding the spread of not only Homo sapiens into the world but Homo erectus before him; also theories as to what happened to the Neanderthals and if they were a seperate species or not are detailed as well. The Tudge book is not perfect though. I think he spends too much time on background prior to discussions of early man. Though interesting, they take up a sizeable section of the book. Some of the asides in the chapter on extinct mammals while interesting are controversial, though he does provide citations for those interested in checking on things. Examples include his mentioning of the theory that giant ground sloths may have been arboreal, that the mastodon genus Cuvieronius may have survived in Central America until several centuries after Christ, and that the dwarf mammoth of Wrangel Island (which survived into historic times, this has been well documented) is actually pictured on a pharaoh's tomb in Egypt, according to some having been illustrated when one was presented as a gift! Still, I wouldn't let some of these controversial statements steer potential readers away from this book. It still provides decent coverage of extinct mammals, concepts in paleontology, and a good coverage of eartly man, his development, and spread around the globe.
