Genome: The Autobiography of a Species in 23 Chapters [Hardcover]

Science writer Matt Ridley has found a way to tell someone else's story without being accused of plagiarism. Genome: The Autobiography of a Species in 23 Chapters delves deep within your body (and, to be fair, Ridley's too) looking for dirt dug up by the Human Genome Project. Each chapter pries one gene out of its chromosome and focuses on its role in our development and adult life, but also goes further, exploring the implications of genetic research and our quickly changing social attitudes toward this information. Genome shies away from the "tedious biochemical middle managers" that only a nerd could love and instead goes for the A-material: genes associated with cancer, intelligence, sex (of course), and more.

Readers unfamiliar with the jargon of genetic research needn't fear; Ridley provides a quick, clear guide to the few words and concepts he must use to translate hard science into English. His writing is informal, relaxed, and playful, guiding the reader so effortlessly through our 23 chromosomes that by the end we wish we had more. He believes that the Human Genome Project will be as world-changing as the splitting of the atom; if so, he is helping us prepare for exciting times--the hope of a cure for cancer contrasts starkly with the horrors of newly empowered eugenicists. Anyone interested in the future of the body should get a head start with the clever, engrossing Genome. --Rob Lightner

HSoon we'll know what's in our genes: next year, the Human Genome Project will have its first-draft map of our 23 chromosomes. Ridley (The Red Queen; The Origins of Virtue) anticipates the genomic news with an inventively constructed, riveting exposition of what we already know about the links between DNA and human life. His inviting prose proposes "to tell the story of the human genome... chromosome by chromosome, by picking a gene from each." That story begins with the basis of life on earth, the DNA-to-RNA-to-protein process (chapter one, "Life," and also chromosome one); the evolution of Homo sapiens (chromosome two, which emerged in early hominids when two ape chromosomes fused); and the discovery of genetic inheritance (which came about in part thanks to the odd ailment called alkaptonuria, carried on chromosome three). Some facts about your life depend entirely on a single gene--for example, whether you'll get the dreadful degenerative disease Huntington's chorea, and if so, at what age (chromosome four, hence chapter four: "Fate"). But most facts about you are products of pleiotropy, "multiple effects of multiple genes," plus the harder-to-study influences of culture and environment. (One asthma-related gene--but only one--hangs out on chromosome five.) The brilliant "whistle-stop tour of some... sites in the genome" passes through "Intelligence," language acquisition, embryology, aging, sex and memory before arriving at two among many bugbears surrounding human genetic mapping: the uses and abuses of genetic screening, and the ongoing debate on "genetic determinism" and free will. Ridley can explain with equal verve difficult moral issues, philosophical quandaries and technical biochemistry; he distinguishes facts from opinions well, and he's not shy about offering either. Among many recent books on genes, behavior and evolution, Ridley's is one of the most informative. It's also the most fun to read. Agent, Felicity Bryan.
