    In this Very Short Introduction, renowned evolutionary scholar Bernard Wood traces the history of paleoanthropology from its beginnings inthe eighteenth century to today's latest fossil finds. Along the way we are introduced to the lively cast of characters, past and present, involved in evolutionary research. Although concentrating on the fossil evidence for human evolution, the book also covers the latest genetic evidence aboutregional variations in the modern human genome that relate to our evolutionary history. Wood draws on over thirty years of experience to provide an insiders view of the field, and demonstrates that our understanding of human evolution is critically dependent on advances in related sciences such aspaleoclimatology, geochronology, systematics, genetics, and developmental biology. This is an ideal introduction for anyone interested in the origins and development of humankind.

New Inquiry Figures focus students on the experimental process, and new Research Method Figures illustrate important techniques in biology. Each chapter ends with a Scientific Inquiry Question that asks students to apply scientific investigation skills to the content of the chapter.

    Yet there is much more to the monarch than its distinctive presence and mythic journeying. In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed--a toxic plant named for the sticky white substance emitted when its leaves are damaged--and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species.The monarch life cycle begins each spring when it deposits eggs on milkweed leaves. But this dependency of monarchs on milkweeds as food is not reciprocated, and milkweeds do all they can to poison or thwart the young monarchs. Agrawal delves into major scientific discoveries, including his own pioneering research, and traces how plant poisons have not only shaped monarch-milkweed interactions but have also been culturally important for centuries. Agrawal presents current ideas regarding the recent decline in monarch populations, including habitat destruction, increased winter storms, and lack of milkweed--the last one a theory that the author rejects. He evaluates the current sustainability of monarchs and reveals a novel explanation for their plummeting numbers.Lavishly illustrated with more than eighty color photos and images, Monarchs and Milkweed takes readers on an unforgettable exploration of one of nature's most important and sophisticated evolutionary relationships.

    This new edition retains the basic format and pedagogical features of previous editions and provides an up-to-date foundation upon which more advanced and specialized knowledge can be built. This essential volume introduces and surveys the broad and complex interrelationships among food ingredients, processing, packaging, distribution and storage, and explores how these factors influence food quality and safety. Reflecting recent advances and emerging technologies in the area, this new edition includes updated commodity and ingredient chapters to emphasize the growing importance of analogs, macro-substitutions, fat fiber and sugar substitutes and replacement products, especially as they affect new product development and increasing concerns for a healthier diet. Revised processing chapters include changing attitudes toward food irradiation, greater use of microwave cooking and microwaveable products, controlled and modified atmosphere packaging and expanding technologies such a extrusion cooking, ohmic heating and supercritical fluid extraction, new information that addresses concerns about the responsible management of food technology, considering environmental, social and economic consequences, as well as the increasing globalization of the food industry. Discussions of food safety an consumer protection including newer phychrotropic pathogens; HAACP techniques for product safety and quality; new information on food additives; pesticides and hormones; and the latest information on nutrition labeling and food regulation. An outstanding text for students with little or no previous instruction in food science and technology, Food Science is also a valuable reference for professionals in food processing, as well as for those working in fields that service, regulate or otherwise interface with the food industry.

    Although evolution provides credible and reliable answers, polls show that many people turn away from science, seeking other explanations with which they are more comfortable.In the book Science, Evolution, and Creationism, a group of experts assembled by the National Academy of Sciences and the Institute of Medicine explain the fundamental methods of science, document the overwhelming evidence in support of biological evolution, and evaluate the alternative perspectives offered by advocates of various kinds of creationism, including intelligent design. The book explores the many fascinating inquiries being pursued that put the science of evolution to work in preventing and treating human disease, developing new agricultural products, and fostering industrial innovations. The book also presents the scientific and legal reasons for not teaching creationist ideas in public school science classes.Mindful of school board battles and recent court decisions, Science, Evolution, and Creationism shows that science and religion should be viewed as different ways of understanding the world rather than as frameworks that are in conflict with each other and that the evidence for evolution can be fully compatible with religious faith. For educators, students, teachers, community leaders, legislators, policy makers, and parents who seek to understand the basis of evolutionary science, this publication will be an essential resource.

    This Penguin Classics edition is edited with an introduction by James Moore and Adrian Desmond.In The Origin of Species, Charles Darwin refused to discuss human evolution, believing the subject too 'surrounded with prejudices'. He had been reworking his notes since the 1830s, but only with trepidation did he finally publish The Descent of Man in 1871. The book notoriously put apes in our family tree and made the races one family, diversified by 'sexual selection' - Darwin's provocative theory that female choice among competing males leads to diverging racial characteristics. Named by Sigmund Freud as 'one of the ten most significant books' ever written, Darwin's Descent of Man continues to shape the way we think about what it is that makes us uniquely human.In their introduction, James Moore and Adrian Desmond, acclaimed biographers of Charles Darwin, call for a radical re-assessment of the book, arguing that its core ideas on race were fired by Darwin's hatred of slavery. The text is the second and definitive edition and this volume also contains suggestions for further reading, a chronology and biographical sketches of prominent individuals mentioned.Charles Darwin (1809-82), a Victorian scientist and naturalist, has become one of the most famous figures of science to date. The advent of On the Origin of Species by Means of Natural Selection in 1859 challenged and contradicted all contemporary biological and religious beliefs.If you enjoyed The Descent of Man, you might like Darwin's On the Origin of Species, also available in Penguin Classics.

    A. Foley, Antiquity), The Human Career has proved to be an indispensable tool in teaching human origins since its publication in 1989. This substantially revised edition retains Richard Klein's innovative approach and incorporates new findings from the past decade.The Human Career chronicles the evolution of people from the earliest primates through the emergence of fully modern humans within the past 200,000 years. Its comprehensive treatment stresses recent advances in knowledge, including, for example, ever more abundant evidence that fully modern humans originated in Africa and spread from there, replacing the Neanderthals in Europe and equally archaic people in Asia. With its coverage of both the fossil record and the archeological record over the 2.5 million years for which both are available, Klein emphasizes that human morphology and behavior evolved together. Throughout the text, Klein presents evidence for alternative points of view, but also does not hesitate to take a position.In addition to outlining the broad pattern of human evolution, The Human Career details the kinds of data that support this pattern, including information on archeological sites, artifacts, fossils, and methods for establishing dates in geological time. With abundant references and hundreds of illustrations, charts, and diagrams, this new edition is unparalleled in its usefulness for teaching human evolution.
