. . A tour de force of a book that begs to be seen as well as to be read."--The Washington Post Book WorldWorld renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are. Shadows of Forgotten Ancestors is a thrilling saga that starts with the origin of the Earth. It shows with humor and drama that many of our key traits--self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics--are rooted in the deep past, and illuminated by our kinship with other animals.Sagan and Druyan conduct a breathtaking journey through space and time, zeroing in on critical turning points in evolutionary history, and tracing the origins of sex, altruism, violence, rape, and dominance. Their book culminates in a stunningly original examination of the connection between primate and human traits. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, Shadows of Forgotten Ancestors is a triumph of popular science.

    Edward O. Wilson eloquently describes how the species of the world became diverse and why that diversity is threatened today as never before. A great spasm of extinction — the disappearance of whole species — is occurring now, caused this time entirely by humans. Unlike the deterioration of the physical environment, which can be halted, the loss of biodiversity is a far more complex problem — and it is irreversible. Defining a new environmental ethic, Wilson explains why we must rescue whole ecosystems, not only individual species. He calls for an end to conservation versus development arguments, and he outlines the massive shift in priorities needed to address this challenge. No writer, no scientist, is more qualified than Edward O. Wilson to describe, as he does here, the grandeur of evolution and what is at stake. "Engaging and nontechnical prose. . . . Prodigious erudition. . . . Original and fascinating insights." — John Terborgh, New York Review of Books, front page review "Eloquent. . . . A profound and enduring contribution." — Alan Burdick, Audubon

    An x-ray microscope would do the trick, or since we're dreaming, perhaps an Asimov-style nanosubmarine (unfortunately, neither is currently feasible). Think of the wonders we could witness firsthand: antibodies atta- ing a virus, electrical signals racing down nerve fibers, proteins building new strands of DNA. Many of the questions puzzling the current cadre of sci- tists would be answered at a glance. But the nanoscale world of molecules is separated from our everyday world of experience by a daunting million-fold difference in size, so the world of molecules is completely invisible. I created the illustrations in this book to help bridge this gulf and allow us to see the molecular structure of cells, if not directly, then in an artistic rendition. I have included two types of illustrations with this goal in mind: watercolor paintings which magnify a small portion of a living cell by one million times, showing the arrangement of molecules inside, and comput- generated pictures, which show the atomic details of individual molecules. In this second edition of The Machinery of Life, these illustrations are presented in full color, and they incorporate many of the exciting scientific advances of the 15 years since the first edition.

    Converging findings from a variety of disciplines are leading to the emergence of a fundamentally new view of the human mind, and with it a new framework for the behavioral and social sciences. First, with the advent of the cognitive revolution, human nature can finally be defined precisely as the set of universal, species-typical information-processing programs that operate beneath the surface of expressed cultural variability. Second, this collection of cognitive programs evolved in the Pleistocene to solve the adaptive problems regularly faced by our hunter-gatherer ancestors--problems such as mate selection, language acquisition, cooperation, and sexual infidelity. Consequently, the traditional view of the mind as a general-purpose computer, tabula rasa, or passive recipient of culture is being replaced by the view that the mind resembles an intricate network of functionally specialized computers, each of which imposes contentful structure on human mental organization and culture. The Adapted Mind explores this new approach--evolutionary psychology--and its implications for a new view of culture.

    Drawing upon the latest in brain research, Pearce traces the development of intelligence from infancy to adulthood, cites five negative common practices that threaten our future, and explores possibilities for the unfolding of human intelligence.

    The book offers an up-to-date description of the analytical tools used in evolutionary explanation: demographics, quantitative genetics, reaction norms, trade-offs, and phylogenetic/comparative analysis. It goes on to discuss the evolution of such major life-history traits as age and size at maturity; clutch size, reproductive investment and size of offspring; reproductive lifespan; and aging. This is an essential text for biologists wishing to understand the evolution of the life cycle and the causes of phenotypic variation in fitness. It is additionally the only book available designed specifically for teaching the subject, with problems and discussion questions at the end of each chapter.

    Over seventy scholars worldwide have collaborated on the Encyclopedia, which is divided into ten main sections. Following a keynote introduction asking simply What makes us human?, the coverage ranges widely: from genetics, primatology and fossil origins to human biology and ecology, brain function and behavior, and demography and disease. Emphasis is placed throughout on the biological diversity of modern people and the increasing convergence of the fossil and genetic evidence for human evolution that has emerged in recent years. Because of the need to look at humankind in the context of our closest relatives, the Encyclopedia also pays particular attention to the evolution and ecology of the living primates--lemurs, lorises, monkeys and apes. It deals with the evolution and ecology of human society, as reconstructed from archaeological remains, and from studies of indigenous peoples and living primates today. It considers the biology of uniquely human abilities such as language and upright walking, and it reviews the biological future of humankind in the face of challenges greater than those ever before experienced. Boxes highlighting key issues and techniques are provided throughout the text, and there are numerous maps, photographs, diagrams, and ready-reference tables--all the reader needs in a single volume to acquire a comprehensive knowledge of how humankind has developed and how scientists set about investigating the origin of our species.

    There are more than 200 species of carnivore in existence which are more diverse than any other living group of vertebrates. The one feature which distinguishes carnivores from all other mammals is the carnassial tooth, designed for shearing meat, although, ironically, their survival has often depended on their ability to survive on diets other than meat. Nearly 40 million years ago the ancestors of two great dynasties of modern predators became divided. In a world dominated by forests the ancestors of the cat remained in the trees, and animals like the sabre-toothed tiger evolved into refined killers. The ancestors of the dog descended to the ground to feed in the clearings and later, with the opening up of the grassy plains and the prey available on these, the dog established its hunting terrain. The book helps to explain the extraordinary myths surrounding the hyena and its peculiar sexuality. It explores how bears, racoons and pandas as a group of carnivores have a truly omnivorous existence, addressing the question - can the vegetarian panda still be classified as a carnivore? The author also looks at the smaller carnivores of the mustella family with their incredible variation in size and lifestyle. They have developed to become both predators and prey and some, such as the skunk, have evolved elaborate defence mechanisms to deter predators. The various species of carnivore depend on each other for their survival, and it is an ironical fact that many skilled and powerful carnivores are more vulnerable than the prey they hunt - resulting in the establishment of intricate carnivore societies, like that of the meerkat.

    In Sexual Strategies, science journalist Mary Batten presents a provocative exploration of female/male behavior in the animal kingdom and its powerful implications for human relationships. Science increasingly acknowledges that much of human behavior is influenced by biology as well as culture. Human reproductive strategies in particular have come to look more like those of the birds and the bees than anyone imagined. In actuality, it is the females, not the males, of many species that actively select their mates. Although Charles Darwin introduced the theory of female mate choice more than a century ago, only in recent years has this controversial idea been appreciated by the scientific community. Studies of female choice are demolishing the age-old myth of the passive female. From fruitflies to primates, Batten shows how female choice truly plays a pivotal role in the evolution of species. By understanding female mate choice and the female's true power in evolution, we see our own complex species with greater clarity. We gain greater insight into why males and females, including men and women, have built-in conflicts in their mating behavior. In addition, Batten illuminates the roots of current social problems related to gender competition and shows that they cannot be fully understood outside a biological context.

    By retracing the steps of men who developed the theory of biological evolution, we see how scientists came to recognize the nature and importance of natural selection. The journey begins in the seventeenth century, when even the most accomplished naturalists knew next to nothing of biology as we understand it today. Steadily increasing knowledge and the quickening pace of research began to uncover much new evidence, and in the middle of the century Charles Darwin and Alfred Russel Wallace incorporated this evidence in a comprehensive theory of evolution. In the twentieth century biology has become steadily more specialized, so the book picks out some of the main developments that bring us to studies of evolution being carried out today.
