Instead, ants decide what to do based on the rate, rhythm, and pattern of individual encounters and interactions--resulting in a dynamic network that coordinates the functions of the colony. Ant Encounters provides a revealing and accessible look into ant behavior from this complex systems perspective.Focusing on the moment-to-moment behavior of ant colonies, Deborah Gordon investigates the role of interaction networks in regulating colony behavior and relations among ant colonies. She shows how ant behavior within and between colonies arises from local interactions of individuals, and how interaction networks develop as a colony grows older and larger. The more rapidly ants react to their encounters, the more sensitively the entire colony responds to changing conditions. Gordon explores whether such reactive networks help a colony to survive and reproduce, how natural selection shapes colony networks, and how these structures compare to other analogous complex systems. Ant Encounters sheds light on the organizational behavior, ecology, and evolution of these diverse and ubiquitous social insects.

    Many studies have supported this, proving that life expectancy is 75 to 90 percent due to habits and only 10 to 25 percent due to genetics. This means that someone who is genetically destined to die at age 100 may not live past age 60 because of poor habits and lifestyle choices that cause accelerated aging and premature death. Conversely, a person can live to 100 and be functionally healthy. In this highly anticipated follow-up, Diana Schwarzbein, M.D., goes beyond the diet she introduced in her first book—which literally helped thousands of people lose weight—and offers a personalized anti-aging program for readers to heal their metabolisms and stop advanced aging in its tracks. Weaving in groundbreaking research and provocative case studies—including her own regeneration and that of her clients—she leads readers through a series of eye-opening questionnaires, which identify where they are on their path to either accelerated or healthy aging. Based on readers’ answers, she leads them to the “how-to” sections, which explain, in easy-to-follow and personalized detail, the steps they need to take to restore healthy functioning. For each unique situation, she covers five areas: Nutrition , Hormone Replacement Therapy (if needed), Tapering Off Toxic Chemicals or Avoiding Them Completely , Cross-Training Exercises and Stress Management. The Schwarzbein Principle II is sure to follow the success of the first book and will help people live a more healthful lifestyle by embracing a regeneration process to prevent and reverse accelerated aging.

Extensive charts, exercises, and formulas demonstrate the use of aroma in healing, prayer, and meditation and in conjunction with vibrational and energetic healing. Covering more than 70 essential oils, this extraordinary guide helps readers call upon the divine power of fragrance to enrich their own spiritual journeys.

    Almost everyone has had a moment when they felt a connection to an animal, almost as if they were communicating. According to animal communicator and author Marta Williams, they probably were. Over the past 13 years, Marta has worked with clients (people and the animals in their lives) to resolve behavior and training problems, find lost animals, assist animals that are ill or dying, and help animals get along with each other. Her human clients have contacted her from all parts of the globe, and her animal clients have included horses, dogs, and cats. In the course of her work, she has come to believe that anyone can learn to communicate with animals and with nature, and this inviting book teaches readers how they can use techniques and exercises to tune in and learn this language.

    And survival is never a given. Somehow, a blind, defenseless tiger kitten must evolve into a deadly, efficient predator; a chimp must learn to distinguish edible plants from lethal poisons; a baby buffalo must be able to pick its mother out of a herd of hundreds. Contrary to common belief, not everything is "hardwired" -- or instinctual -- in the animal kingdom. Many skills a wild animal needs to thrive, to grow, to be what nature intended, must be developed through play, painstaking teaching, and often treacherous trial and error. The coming-of-age processes of the myriad creatures of plain, forest, ocean, and jungle are truly fascinating and often astonishing natural events.In Becoming a Tiger, Susan McCarthy, co-author of the critically acclaimed New York Times bestseller When Elephants Weep, offers readers an in-depth look into the amazing ways baby animals learn not only about themselves, but about their world and ours -- and how to survive in both. Based on extensive scientific research done in the lab, in controlled "natural" settings, as well as in the wild, her findings provide stunning new insights into the lives and development of Earth's nonhuman inhabitants -- not only tigers, but lions, bears, bats, rats, birds, dolphins, whales, apes, elephants, and dozens of other species.Sharing stories and discoveries at once captivating, funny, breathtaking, provocative, and heartwarming, Susan McCarthy carries us on a remarkable journey into untamed places, immersing us in the fascinating, complex, and hitherto unimagined societies and cultures of the beasts and birds. Along the way she shines a brilliant new light on subjects scientists, biologists, and zoologists have only begun to explore, revealing startling truths about the behavior, and sometimes humanlike foibles, of creatures great and small.Warm, informative, and beautifully written, Becoming a Tiger is an enthralling reading experience for animal lovers everywhere. In the transformation tales of playful pups, big-footed cubs, and scrawny chicks becoming deadly hunters, able foragers, and deft nest-builders are valuable and enriching life lessons for members of our own inquisitive, ever-developing species.

    In his provocative new book, Guy Claxton draws on the latest findings in neuroscience and psychology to reveal how our bodies—long dismissed as mere conveyances—actually constitute the core of our intelligent life. From the endocrinal means by which our organs communicate to the instantaneous decision-making prompted by external phenomena, our bodies are able to perform intelligent computations that we either overlook or wrongly attribute to our brains.   Embodied intelligence is one of the most exciting areas in contemporary philosophy and neuropsychology, and Claxton shows how the privilege given to cerebral thinking has taken a toll on modern society, resulting in too much screen time, the diminishment of skilled craftsmanship, and an overvaluing of white-collar over blue-collar labor. Discussing techniques that will help us reconnect with our bodies, Claxton shows how an appreciation of the body’s intelligence will enrich all our lives.

    This discovery prompted a complete reevaluation of previous evidence for human origins.In the years since this dramatic discovery Johanson has continued to scour East Africa's Great rift Valley for the earliest evidence of human origins. In 1975 this team unearthed the "First Family", an unparalleled fossil assemblage of 13 individuals dating back to 3.2 million years ago; and in 1986 at the Rift's most famous location, Olduvai Gorge, this same team discovered a 1.8 million-year-old partial adult skeleton that necessitated a reassessment of the earliest members of our own genus Homo.Johanson's fieldwork continues unabated and recently more fossil members of Lucy's family have been found, including the 1992 discovery of the oldest, most complete skull of her species, with future research now planned for 1996 in the virtually unexplored regions of the most northern extension of the Rift Valley in Eritrea.From Lucy to Language is a summing up of this remarkable career and a stunning documentary of human life through time on Earth. It is a combination of the vital experience of field work and the intellectual rigor of primary research. It is the fusion of two great writing talents: Johanson and Blake Edgar, an accomplished science writer, editor of the California Academy of Sciences' Pacific Discovery, and co-author of Johanson's last book, Ancestors.From Lucy to Language is one of the greatest stories ever told, bracketing the timeline between bipedalism and human language. Part I addresses the central issues facing anyone seeking to decipher the mystery of human origins. In this section the authors provide answers to the basics -- "What are our closest living relatives?" -- tackle the controversial -- "What is race?" -- and contemplate the imponderables -- "Why did consciousness evolve?"From Lucy to Language is an encounter with the evidence. Early human fossils are hunted, discovered, identified, excavated, collected, preserved, labeled, cleaned, reconstructed, drawn, fondled, photographed, cast, compared, measured, revered, pondered, published, and argued over endlessly. Fossils like Lucy have become a talisman of sorts, promising to reveal the deepest secrets of our existence. In Part II the authors profile over fifty of the most significant early human fossils ever found. Each specimen is displayed in color and at actual size, most of them in multiple views. With them the authors present the cultural accoutrements associated with the fossils: stone tools which evidence increasing sophistication over time, the earliest stone, clay, and ivory art objects, and the culminating achievement of the dawn of human consciousness -- the magnificent rock and cave paintings of Europe, Africa, Australia, and the Americas.In the end From Lucy to Language is a reminder and a challenge. Like no species before us, we now seem poised to control vast parts of the planet and its life. We possess the power to influence, if not govern, evolution. For that reason, we must not forget our link to the natural world and our debt to natural selection. We need to "think deep", to add a dose of geologic time and evolutionary history to our perspective of who we are, where we came from, and where we are headed. This is the most poignant lesson this book has to offer.

    Our instincts—for food, sex, or territorial protection— evolved for life on the savannahs 10,000 years ago, not in today’s world of densely populated cities, technological innovations, and pollution. We now have access to a glut of larger-than-life objects, from candy to pornography to atomic weapons—that gratify these gut instincts with often-dangerous results. Animal biologists coined the term “supernormal stimuli” to describe imitations that appeal to primitive instincts and exert a stronger pull than real things, such as soccer balls that geese prefer over eggs. Evolutionary psychologist Deirdre Barrett applies this concept to the alarming disconnect between human instinct and our created environment, demonstrating how supernormal stimuli are a major cause of today’s most pressing problems, including obesity and war. However, Barrett does more than show how unfettered instincts fuel dangerous excesses. She also reminds us that by exercising self-control we can rein them in, potentially saving ourselves and civilization. 55 illustrations.

      From an evolutionary viewpoint, Wilson argues, altruism is inextricably linked to the functional organization of groups. “Groups that work” undeniably exist in nature and human society, although special conditions are required for their evolution. Humans are one of the most groupish species on earth, in some ways comparable to social insect colonies and multi-cellular organisms. The case that altruism evolves in all social species is surprisingly simple to make.   Yet the implications for human society are far from obvious. Some of the most venerable criteria for defining altruism aren’t worth caring much about, any more than we care much whether we are paid by cash or check. Altruism defined in terms of thoughts and feelings is notably absent from religion, even though altruism defined in terms of action is notably present. The economic case for selfishness can be decisively rejected. The quality of everyday life depends critically on people who overtly care about the welfare of others. Yet, like any other adaptation, altruism can have pathological manifestations. Wilson concludes by showing how a social theory that goes beyond altruism by focusing on group function can help to improve the human condition.
