From its first edition, Life has set the standard for experiment-based introductory biology texts. There is no stronger textbook for helping students understand not just what we know (scientific facts), but how we know it (the experimental process that leads to their discovery).

The new edition of Life builds upon this tradition, teaching fundamental concepts and showcasing significant research while responding to changes in biology education with new design and learning features, new technologies, and new assessment resources.

DAVID SADAVA is the

DAVID M. HILLIS is the

Pritzker Family Foundation Professor of Biology, Emeritus at the Keck Science Center of Claremont McKenna, Pitzer, and Scripps, three of The Claremont Colleges. In addition, he is Adjunct Professor of Cancer Cell Biology at the City of Hope Medical Center in Duarte, California. Twice winner of the Huntoon Award for superior teaching, Dr. Sadava has taught courses on introductory biology, biotechnology, biochemistry, cell biology, molecular biology, plant biology, and cancer biology.

In addition to Life: The Science of Biology and Principles of Life, he is the author or coauthor of books on cell biology and on plants, genes, and crop biotechnology.

His research has resulted in many papers coauthored with his students, on topics ranging from plant biochemistry to pharmacology of narcotic analgesics to human genetic diseases. For the past 15 years, he has investigated multi-drug resistance in human small-cell lung carcinoma cells with a view to understanding and overcoming this clinical challenge. At the City of Hope, his current work focuses on new anti-cancer agents from plants. He is the featured lecturer in “Understanding Genetics: DNA, Genes and their Real-World Applications,“ a video course for The Great Courses series.

Alfred W. Roark Centennial Professor in Integrative Biology and the Director of the Dean’s Scholars Program at the University of Texas at Austin, where he also has directed the School of Biological Sciences and the Center for Computational Biology and Bioinformatics. Dr. Hillis has taught courses in introductory biology, genetics, evolution, systematics, and biodiversity. He has been elected to the National Academy of Sciences and the American Academy of Arts and Sciences, awarded a John D. and Catherine T. MacArthur fellowship, and has served as President of the Society for the Study of Evolution and of the Society of Systematic Biologists. He served on the National Research Council committee that wrote the report BIO 2010: Transforming Undergraduate Biology Education for Research Biologists. His research interests span much of evolutionary biology, including experimental studies of viral evolution, empirical studies of natural molecular evolution, applications of phylogenetics, analyses of biodiversity, and evolutionary modeling. He is particularly interested in teaching and research about the practical applications of evolutionary biology.

H. CRAIG HELLER is the Lorry I. Lokey/Business Wire Professor in Biological Sciences and Human Biology at Stanford University. He has taught in the core biology courses at Stanford since 1972 and served as Director of the Program in Human Biology, Chairman of the Biolo-gical Sciences Department, and Associate Dean of Research. Dr. Heller is a fellow of the American Association for the Advancement of Science and a recipient of the Walter J. Gores Award for excellence in teaching and the Kenneth Cuthberson Award for Exceptional Service to Stanford University. His research is on the neurobiology of sleep and circadian rhythms, mammalian hibernation, the regulation of body temperature, the physiology of human performance, and the neurobiology of learning. He has done research on a huge variety of animals and physiolo-gical problems, including from sleeping kangaroo rats, diving seals, hibernating bears, photo-periodic hamsters, and exercising athletes. Dr. Heller has extended his enthusiasm for promoting active learning via the development of a two-year curriculum in human biology for the middle grades, through the production of Virtual Labs— interactive computer-based modules to teach physiology.

MAY BERENBAUM is the Swanlund Professor and Head of the Department of Entomology at the University of Illinois at Urbana-Champaign. She has taught courses in introductory animal biology, entomology, insect ecology and chemical ecology and has received awards at the regional and national levels teaching from the Entomological Society of America. A fellow of the National Academy of Sciences, the American Academy of Arts and Sciences, and the American Philosophical Society, she served as President of the American Institute for Biological Sciences in 2009 and currently serves on the Board of Directors of AAAS. Her research addresses insect-plant coevolution from molecular mechanisms of detoxification to impacts of herbivory on community structure.

Concerned with the practical application of ecological and evolutionary principles, she has examined impacts of genetic engineering, global climate change, and invasive species on natural and agricultural ecosystems. In recognition of her work, she received the 2011 Tyler Prize for Environmental Achievement. Devoted to fostering science literacy, she has published numerous articles and five books on insects for the general public.

Principles of Life, First Edition David M. Hillis, The University of Texas at Austin David Sadava, The Claremont Colleges H. Craig Heller, Stanford University Mary V. Price, Emerita, The University of California, Riverside © 2012, co-published by Sinauer Associates, Inc., and W. H. Freeman and Company

Hardback ISBN: 978-1-4292-8657-2

Written in the spirit of the reform movement that is reinvigorating the introductory majors course, Principles of Life cuts through the thicket of excessive detail to focus on what matters most in the study of biology today. Students explore the most essential biological ideas and information in the context of the field’s defining experiments, and are actively engaged in analyzing research data. The result is a textbook that is hundreds of pages shorter (and significantly less expensive) than current majors introductory books.

This title may not be available in all areas. Please contact your representative for more information.

“Our department adopted Principles of Life last year as part of our effort to refocus our introductory sequence in a manner consistent with the NSF/AAAS mandate ‘Vision and Change in Undergraduate Biology Education.’ While the text is substantially slimmer than the dominant introductory biology books in the market, we found that essential concepts and content are well represented. I found that I was able to address foundational material as deeply as I had in the past, but I was able to do so more efficiently. As a result—for the first time in eight years teaching this course—I was able to address all of the major sections I’d aspired to teach in the semester. I look forward to using the text again this fall.”
