Revised to reflect the latest research in the field, this book emphasizes the relationships and concepts that link cell and tissue structures with their functions. A bonus image library CD-ROM featuring all the photos and illustrations from the text with "zoom in" and "zoom out" capability is also included.

    The sixth edition explores core concepts in considerable depth and presents experimental detail when it helps to explain and reinforce the concepts. The majority of discussions have been modified to reflect the latest changes in the field. The book also builds on its strong illustration program by opening each chapter with “VIP” art that serves as a visual summary for the chapter. Over 60 new micrographs and computer-derived images have been added to enhance the material. Biologists benefit from these changes as they build their skills in making the connection. Doody Review Services Reviewer: Bruce A. Fenderson, PhD(Thomas Jefferson University) Description: The author expertly organizes, explains, and illustrates the chemical and cellular basis of life on Earth in this comprehensive and exciting introduction to cell and molecular biology. The 18 fascinating chapters cover topics ranging from control of gene expression to mechanisms of immune response. There is even a chapter on laboratory techniques. The focus of the book is on biological chemistry, with an emphasis on core concepts and experimental approaches. Purpose: The purpose is to provide a textbook for an introductory course in cell and molecular biology. The author hopes that students will visualize a world filled with "giant molecules and minuscule structures" that constitute the chemistry of life. He encourages students to consider the evidence that is presented to support a biological model, think of alternate explanations, and plan experiments that may lead to new hypotheses. One of the author's goals is to help students develop their independent, critical-thinking skills. Audience: This is an excellent companion textbook for undergraduate and graduate-level courses in cell and molecular biology. It is written for students across a wide range of life science disciplines

    Every person alive today is descended from him. How did this real-life Adam wind up as the father of us all? What happened to the descendants of other men who lived at the same time? And why, if modern humans share a single prehistoric ancestor, do we come in so many sizes, shapes, and races?Examining the hidden secrets of human evolution in our genetic code, Spencer Wells reveals how developments in the revolutionary science of population genetics have made it possible to create a family tree for the whole of humanity. Replete with marvelous anecdotes and remarkable information, from the truth about the real Adam and Eve to the way differing racial types emerged, The Journey of Man is an enthralling, epic tour through the history and development of early humankind.

    The stewards of Earth, these organisms transformed the chemistry of our planet to make it habitable for plants, animals, and us. Life's Engines takes readers deep into the microscopic world to explore how these marvelous creatures made life on Earth possible--and how human life today would cease to exist without them.Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built--and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.A vibrantly entertaining book about the microbes that support our very existence, Life's Engines will inspire wonder about these elegantly complex nanomachines that have driven life since its origin. It also issues a timely warning about the dangers of tinkering with that machinery to make it more "efficient" at meeting the ever-growing demands of humans in the coming century.

    The sixteenth and seventeenth centuries witnessed the Copernican Revolution, which bodychecked the Earth as the pivot point of creation and joined us with the rest of the cosmos as one planet among many orbiting the Sun. Three centuries later came the second great scientific revolution: the Darwinian Revolution. It removed us from a distinct, divine biological status to place us wholly in the ebb and flow of all terrestrial life. This book describes how we’re in the midst of a third great scientific revolution, five centuries in the making: the Stardust Revolution. It is the merging of the once-disparate realms of astronomy and evolutionary biology, and of the Copernican and Darwinian Revolutions, placing life in a cosmic context. This book takes readers on a grand journey that begins on the summit of California’s Mount Wilson, where astronomers first realized that the universe is both expanding and evolving, to a radio telescope used to identify how organic molecules—the building blocks of life—are made by stars. It’s an epic story told through a scientific cast that includes some of the twentieth century’s greatest minds—including Nobel laureate Charles Townes, who discovered cosmic water—as well as the most ambitious scientific explorers of the twenty-first century, those racing to find another living planet. Today, an entirely new breed of scientists—astrobiologists and astrochemists—are taking the study of life into the space age. Astrobiologists study the origins, evolution, and distribution of life, not just on Earth, but in the universe. Stardust science is filling in the missing links in our evolutionary story, ones that extend our family tree back to the stars.

    In The Horse, the journalist and equestrienne Wendy Williams brings that story brilliantly to life.Williams chronicles the 56-million-year journey of horses as she visits with horse experts around the world, revealing what our biological affinities and differences can tell us about the bond between horses and humans, and what our noble companion may think and feel. Indeed, recent scientific breakthroughs regarding the social and cognitive capacities of the horse and its ability to adapt to changing ecosystems indicate that this animal is a major evolutionary triumph.Williams charts the course that leads to our modern Equus-from the protohorse to the Dutch warmbloods, thoroughbreds, and miniature horses of the twenty-first century. She observes magnificent ancient cave art that signals a deep respect and admiration for horses well before they were domesticated, visits the mountains of Wyoming with an expert in equine behavior to understand the dynamics of free-roaming mustangs, witnesses the fluid gracefulness of the famous Lipizzaners of Vienna, contemplates what life is like for the sure-footed, mustachioed Garrano horses who thrive on the rugged terrain of Galicia, celebrates the Takhi horses of Mongolia, and more. She blends profound scientific insights with remarkable stories to create a unique biography of the horse as a sentient being with a fascinating past and a finely nuanced mind.The Horse is a revelatory account of the animal who has been at our side through the ages, carrying us into battle and traveling with us across the plains. Enriched by Wendy Williams's own experience with horses, The Horse is a masterful work of narrative nonfiction that pays tribute to this champion of the natural world.

    How is it that Homo sapiens formed such a special relationship with what, on the face of it, is a most unlikely ally? It is more than just a story of domestication but an astonishing example of the co-evolution of two species, man and wolf, to each others' mutual benefit. This co-evolution was a vital step in helping Homo sapiens overcome competition from other human species and to expand in numbers from relative obscurity on the margins towards the overwhelming numerical superiority and influence that we enjoy today. The book draws on the rich scientific detail of the genomes, both dog and human, that has accumulated over the past two decades. In each case we see a clear pattern of the origins of both species, resolving questions that have puzzled scientists for centuries. Sykes explores the breadth of this `special relationship' between man and dog. We know that dogs descend from wolves. We know that their domesticated descendants form close bonds with ourselves and there are a multitude of theories to account for our compatible social organisations. But to a geneticist, this is nowhere near powerful enough to explain this most peculiar situation. Many theories explore what it was that propelled Homo sapiens from the position of a scarce, medium-sized primate to the position of complete domination that we enjoy today. The ability to control fire, the evolution of language and the invention of agriculture are three prominent examples. Sykes crucially adds a fourth: our transformation of the wolf into the multi-purpose helpmate that is the dog. We owe our dominance and our survival to the dog.

    Barash, there are even more things that we don't know, genuine evolutionary mysteries that perplex the best minds in biology. Paradoxically, many of these mysteries are very close to home, involving some of the most personalaspects of being human.Homo Mysterious examines a number of these evolutionary mysteries, exploring things that we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse. Why do women experience orgasm? Why do men have a shorterlifespan than women? Why does homosexuality exist? Why does religion exist in virtually every culture? Why do we have a fondness for the arts? Why do we have such large brains? And why does consciousness exist? Readers are plunged into an ocean of unknowns--the blank spots on the human evolutionarymap, the terra incognita of our own species--and are introduced to the major hypotheses that currently occupy scientists who are attempting to unravel each puzzle (including some solutions proposed here for the first time). Throughout the book, readers are invited to share the thrill of science atits cutting edge, a place where we know what we don't know, and, moreover, where we know enough to come up with some compelling and seductive explanations.Homo Mysterious is a guide to creative thought and future explorations, based on the best, most current thinking by evolutionary scientists. It captures the allure of the not-yet-known for those interested in stretching their scientific imaginations.

    Its contributors—some of the most brilliant young scientists working today—provide not only an introduction to their cutting-edge research, but discuss the social, ethical, and philosophical ramifications of their work. With essays covering fields as diverse as astrophysics, paleoanthropology, climatology, and neuroscience, What's Next? is a lucid and informed guide to the new frontiers of science.

    In his hallmark friendly style, he explores the universal impact of being the right size. By examining stories ranging from Alice in Wonderland to Gulliver's Travels, he shows that humans have always been fascinated by things big and small. Why then does size always reside on the fringes of science and never on the center stage? Why do biologists and others ponder size only when studying something else--running speed, life span, or metabolism? Why Size Matters, a pioneering book of big ideas in a compact size, gives size its due by presenting a profound yet lucid overview of what we know about its role in the living world. Bonner argues that size really does matter--that it is the supreme and universal determinant of what any organism can be and do. For example, because tiny creatures are subject primarily to forces of cohesion and larger beasts to gravity, a fly can easily walk up a wall, something we humans cannot even begin to imagine doing.Bonner introduces us to size through the giants and dwarfs of human, animal, and plant history and then explores questions including the physics of size as it affects biology, the evolution of size over geological time, and the role of size in the function and longevity of living things.As this elegantly written book shows, size affects life in its every aspect. It is a universal frame from which nothing escapes.

    All animals, human or otherwise, thrive when they mimic key elements of life in their natural habitat. From diet to movement to sleep, this evolutionary perspective sheds light on some of our most pressing health concerns. What is causing the rise of chronic conditions, such as obesity, diabetes, and depression? Is eating red meat going to kill you? Is avoiding the sun actually the best way to avoid skin cancer? Durant takes readers on a thrilling ride to the Paleolithic and beyond, unlocking the health secrets of our ancient ancestors. What do obese gorillas teach us about weight loss? How can Paleolithic skulls contain beautiful sets of teeth? Why is the Bible so obsessed with hygiene? What do NASA astronauts teach us about getting a good night’s sleep? And how are Silicon Valley techies hacking the human body? Blending science and culture, anthropology and philosophy, John Durant distills the lessons from his adventures and shows how to apply them to day-to-day life, teaching people how to construct their own personal “habitat” that will enable them to thrive. The book doesn’t just address what we eat, but why we eat it; not just how to exercise, but the purpose of functional movement; not just being healthy, but leading a purposeful life. Combining the best of ancient wisdom with cutting edge science, Durant crafts a vision of health that is both fresh and futuristic.

    This concept of the umwelt has become enormously important within posthumanist philosophy, influencing such figures as Heidegger, Merleau-Ponty, Deleuze and Guattari, and, most recently, Giorgio Agamben, who has called Uexküll "a high point of modern antihumanism."A key document in the genealogy of posthumanist thought, A Foray into the Worlds of Animals and Humans advances Uexküll's revolutionary belief that nonhuman perceptions must be accounted for in any biology worth its name; it also contains his arguments against natural selection as an adequate explanation for the present orientation of a species' morphology and behavior. A Theory of Meaning extends his thinking on the umwelt, while also identifying an overarching and perceptible unity in nature. Those coming to Uexküll's work for the first time will find that his concept of the umwelt holds out new possibilities for the terms of animality, life, and the whole framework of biopolitics itself.
