Dogs are smarter than cats, dolphins and chimps are more clever than both, and we who determine the rankings top the scale--or so we think. But are we thinking clearly? To appreciate the mental abilities of the owl and the pussycat, the tortoise and the hare, requires a commitment to unraveling the nature of intelligence--a tricky and controversial proposition that Sonja Yoerg sets out to explore in this learned, lucid, and entertaining book about our complicated, often erroneous notions about animal intelligence.

With forays into evolutionary biology, behavioral science, and comparative psychology, Clever as a Fox reveals the promise and pitfalls inherent in any attempt to assess animal intelligence. Along with the concepts we deploy to define and compare intelligence, Yoerg looks at the expectations and prejudices that cloud our judgment of the animal mind, perceptions shaped as much by Aesop and Disney as by direct observation of our fellow creatures. And because such perceptions are inextricably linked with judgments of value--ideas about animal mentality have much to do with which species end up on our laps and which on our plates--this deeply revealing look at how we think about animal intelligence should help us use our own intelligence more wisely.

The human genome is the key to what makes us human. Composed of the many different genes found in our cells, it defines our possibilities and limitations as members of the species. The ultimate goal of the pioneering project outlined in this book is to map our genome in detail—an achievement that will revolutionize our understanding of human development and the expression of both our normal traits and our abnormal characteristics, such as disease. The Code of Codes is a collective exploration of the substance and possible consequences of this project in relation to ethics, law, and society as well as to science, technology, and medicine.

The many debates on the Human Genome Project are prompted in part by its extraordinary cost, which has raised questions about whether it represents the invasion of biology by the kind of Big Science symbolized by high-energy accelerators. While addressing these matters, this book recognizes that far more than money is at stake. Its intent is not to advance naive paeans for the project but to stimulate thought about the serious issues—scientific, social, and ethical—that it provokes. The Code of Codes comprises incisive essays by stellar figures in a variety of fields, including James D. Watson and Walter Gilbert and the social analysts of science Dorothy Nelkin and Evelyn Fox Keller. An authoritative review of the scientific underpinnings of the project is provided by Horace Freeland Judson, author of the bestselling Eighth Day of Creation.

The book’s broad and balanced coverage and the expertise of its contributors make The Code of Codes the most comprehensive and compelling exploration available on this history-making project.

This book is a concise study of the structure and function of vertebrate respiratory systems. It describes not only the individual organ systems, but also the relationship of these systems to each other and to the animal's environment. For example, the author emphasizes that a proper understanding of respiration involves a consideration of the external environment as a source of oxygen as well as the biochemistry of the cell; and, from the evolutionary point of view, that physiological changes in the respiratory and circulatory systems are dominated by the origin of the land habit.

The author's approach to the subject exemplifies that trend to the amalgamation of Zoology and Physiology, which has become increasingly marked at universities and schools in recent years. This synthesis requires, broadly, a knowledge of classical comparative anatomy, ecology, evolution, physiology and biochemistry; an enormous task, but nevertheless one in which the zoologist holds a central position. This book indicates the nature of such an eclectic approach, with the animal, in its environment and its evolution, as its focal point.

Covering a rapidly changing field of research the author refers to many recent views and indicates where these differ from those commonly accepted.

The biological functions of coloration in animals are sometimes surprising. Color can attract mates, intimidate enemies, and distract predators. But color patterns can also conceal animals from detection. Concealing coloration is unusual because it is an adaptation not only to the visual features of the environment but also to the perceptual and cognitive capabilities of other organisms. Judy Diamond and Alan Bond bring to light the many factors at work in the evolution of concealing coloration.

Animals that resemble twigs, tree bark, stones, and seaweed may appear to be perfect imitations, but no concealment strategy is without flaws. Amid the clutter of the natural world, predators search for minute, telltale clues that will reveal the identity of their prey. Predators have remarkable abilities to learn to discriminate the fake from the real. But prey have their own range of defensive tactics, evolving multiple appearances or the ability to change color at will. Drawing on modern experimental evidence of the functional significance of animal color strategies, Diamond and Bond offer striking illustrations of how the evolution of features in one organism can be driven by the psychology of others.

Concealing Coloration in Animals takes readers on a scientific adventure that explores creatures inside mats of floating seaweed, mice and lizards on desert rocks and sand, and rare parrots in the rainforest of New Zealand. Color photographs extensively document the mind-boggling array of deceptive strategies animals use to blend in, mislead, or vanish from view.

Milk is the only food mammals produce naturally to feed their offspring. The human species is the only one that takes milk from other animals and consumes it beyond weaning age. Cultures of Milk contrasts the practices of the world’s two leading milk producers, India and the United States. In both countries, milk is considered to have special qualities. Drawing on ethnographic and scientific studies, popular media, and government reports, Andrea Wiley reveals that the cultural significance of milk goes well beyond its nutritive value.

Shifting socioeconomic and political factors influence how people perceive the importance of milk and how much they consume. In India, where milk is out of reach for many, consumption is rising rapidly among the urban middle class. But milk drinking is declining in America, despite the strength of the dairy industry. Milk is bound up in discussions of food scarcity in India and food abundance in the United States. Promotion of milk as a means to enhance child growth boosted consumption in twentieth-century America and is currently doing the same in India, where average height is low. Wiley considers how variation among populations in the ability to digest lactose and ideas about how milk affects digestion influence the type of milk and milk products consumed. In India, most milk comes from buffalo, but cows have sacred status for Hindus. In the United States, cow’s milk has long been a privileged food, but is now facing competition from plant-based milk.
