It takes a brave writer to tackle the truly Herculean task of describing
The Variety of Life with the astronomical numbers of organisms living today, let alone all those that have fallen by the wayside over the billions of years of life on Earth. No one is quite sure how many living species there are, but it is estimated to be somewhere between 10 million and 100 million. Fortunately, since the days of the great Swedish naturalist Linnaeus, around 250 years ago, life has been grouped and classified into hierarchical schemes. As a result, it is possible to encompass this enormous variety of life by describing the relatively few groups into which it can be clustered. And, since the mid-19th century and the Darwin-Wallace theory of evolution by natural selection, classification has taken on an extra, evolutionary dimension.
Colin Tudge, a well-known British science writer, has training in whole animal biology and a self-proclaimed love for the natural-historical foray among our fellow creatures. The first part of this big book (all of 90 pages) deals with the thorny problems of what Tudge rightly calls the craft and science of classification. Since the 1950s, the word cladistics has terrorized many traditional naturalists and biologists. But it is here to stay, and Tudge provides a very welcome guide that will be invaluable to both lay people and students.
The bulk of the text, nearly 500 pages, forms part II and includes the descriptions of the main groups, from the most primitive (alpha proteobacteria) prokaryotes to Eupatorium, a large genus of 1,800 or so species of plant. In between these two groups, at either end of the biological spectrum, lie all the more familiar bugs and beasts, including ourselves. Inevitably, given so many millions of organisms, difficult choices have to be made. Some groups are only dealt with at phylum level (for example, brachiopods), while others are detailed down to family level (for example, primates). Some extinct groups (not surprisingly, the dinosaurs) get a look, but not many overall. The short epilogue concerns conservation and is followed by a useful reference list of sources and an index. Altogether, the 600-odd pages are enlivened with a large number of excellent black-and-white drawings of individual organisms and diagrams illustrating evolutionary relationships. For all natural historians and anyone interested in biology, the The Variety of Life is a must. --Douglas Palmer, Amazon.co.uk

From Library Journal
Science writer Tudge (The Time Before History) has taken an enormous subject--the inventory of all living things past and present--and created a very readable work on the science of classification and the classifications of life. He draws from the work of dozens of scientists from around the world as he endeavors to bring the theories into a workable whole. Tudge imbues his work with a contagious passion for an area of biology that has dropped in profile in recent decades. The first part of the book serves as a well-developed introduction to the history, philosophy, and potential future of classification suitable for the interested lay reader, the undergraduate biology student, or the biologist specializing in any area other than taxonomy. The latter part of the book contains the actual survey of all living things. One of the highlights of this work is Tudge's writing style. He diligently explains every concept using a wide variety of clear examples and down-to-earth analogies. Highly recommended for science collections in both public and academic libraries.
