As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors that resembled tiny deer to carnivorous monsters stalking lakes and rivers and to serpentlike denizens of the coast. Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society. The reader senses the excitement of the digs as well as the rigors faced by scientific researchers, for whom each new insight gives rise to even more questions, and for whom at times the logistics of just staying alive may trump all science. In his search for an understanding of how modern whales live their lives, Thewissen also journeys to Japan and Alaska to study whales and wild dolphins. He finds answers to his questions about fossils by studying the anatomy of otters and porpoises and examining whale embryos under the microscope. In the book's final chapter, Thewissen argues for approaching whale evolution with the most powerful tools we have and for combining all the fields of science in pursuit of knowledge.

    It shows how political orientations across space and time arise from three clusters of measurable personality traits. These clusters entail opposing attitudes toward tribalism, inequality, and differing perceptions of human nature. Together, these traits are by far the most powerful cause of left-right voting, even leading people to regularly vote against their economic interests.      As this book explains, our political personalities also influence our likely choice of a mate, and shape society's larger reproductive patterns. Most importantly of all, it tells the evolutionary stories of these crucial personality traits, which stem from epic biological conflicts.     Based on dozens of exciting new insights from primatology, genetics, neuroscience, and anthropology, this groundbreaking work brings core concepts to life through current news stories and personalities. For instance, readers will meet Glenn Beck and Hugo Chavez and come to understand the underlying evolutionary forces they represent. By blending serious research with relevant contemporary examples, Our Political Nature casts important light onto the ideological clashes that so dangerously divide and imperil our world today.

    But aging does not have to mean decline. World-renowned surgeon Dr. Steven Gundry has been treating mature patients for most of his career. He knows that everyone thinks they want to live forever, until they hit middle age and witness the suffering of their parents and even their peers. So how do we solve the paradox of wanting to live to a ripe old age—but enjoy the benefits of youth?This groundbreaking book holds the answer. Working with thousands of patients, Dr. Gundry has discovered that the “diseases of aging” we most fear are not simply a function of age; rather, they are a byproduct of the way we have lived over the decades. In The Longevity Paradox, he maps out a new approach to aging well—one that is based on supporting the health of the “oldest” parts of us: the microorganisms that live within our bodies.Our gut bugs—the bacteria that make up the microbiome—largely determine our health over the years. From diseases like cancer and Alzheimer’s to common ailments like arthritis to our weight and the appearance of our skin, these bugs are in the driver’s seat, controlling our quality of life as we age.The good news is, it’s never too late to support these microbes and give them what they need to help them—and you—thrive. In The Longevity Paradox, Dr. Gundry outlines a nutrition and lifestyle plan to support gut health and live well for decades to come. A progressive take on the new science of aging, The Longevity Paradox offers an action plan to prevent and reverse disease as well as simple hacks to help anyone look and feel younger and more vital.

    Now he takes the reader through an average day in and around an average house, showing us the fascinating science beneath the surface-from the static between radio stations, to the millions of pillow mites that snuggle up with us every night, from the warm electric fields wrapped around a light bulb filament, to what really makes the garden roses red. With wit, whimsy, and delightful detail, David Bodanis explains it all in ordinary words--on an extraordinary tour...

    This book examines how science comes to be used as a substitute for religion and points out how badly that role distorts it. Her argument is flawlessly insightful: a punch, compelling, lively indictment of these misuses of science. Both the book and its author are true classics of our time.

    This book engaged some of the hardest questions in the evolution debate, and it showed the ever-cautious Darwin at his boldest. If Darwin had one goal with Expression , it was to demonstrate the power of his theories for explaining the origin of our most cherished human qualities: morality and intellect. As Darwin explained, "He who admits, on general grounds, that the structure and habits of all animals have been gradually evolved, will look at the whole subject of Expression in a new and interesting light."

    New genetic technologies are transforming the way we live and promise treatments for otherwise incurable diseases. But these advances are also generating controversy, particularly surrounding issues such as cloning and designer babies. In 50 Genetics Ideas, Mark Henderson distils the central ideas of genetics in a series of clear and concise essays. Beginning with the theory of evolution, and covering such topics as the genome and how nature and nurture work together, he not only illuminates the role of genes in shaping our behaviour and sexuality, but also the very latest, cutting-edge developments in gene therapy and artificial life. Accessible and informative, 50 Genetics Ideas is a timely introduction to this young and ground-breaking strand of science.

    Today, more than sixty years later, members of a new generation of scientists are attempting to create life from the ground up. Science has moved forward in leaps and bounds since Schrodinger's time, but our understanding of what does and does not constitute life has only grown more complex. An era that has already seen computer chip-implanted human brains, genetically engineered organisms, genetically modified foods, cloned mammals, and brain-dead humans kept alive by machines is one that demands fresh thinking about the concept of life. While a segment of our national debate remains stubbornly mired in moral quandaries over abortion, euthanasia, and other right to life issues, the science writer Ed Regis demonstrates how science can and does provide us with a detailed understanding of the nature of life. Written in a lively and accessible style, and synthesizing a wide range of contemporary research, What Is Life? is a brief and illuminating contribution to an age-old debate.

    In this book you will see how commonly performed operations can be found to be useless or even harmful when properly evaluated. That these claims come from an experienced, practicing orthopedic surgeon who performs many of these operations himself, makes the unsettling argument particularly compelling. Of course no surgeon is recommending invasive surgery in bad faith, but Ian Harris argues that the evidence for the success for many common operations, including knee arthroscopies, back fusion or cardiac stenting, become current accepted practice without full examination of the evidence.

    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.

    The latest studies are revealing exciting new discoveries, such as how the DNA and related chemical compounds in our cells work together to direct the processes of life. Scientists are not only unraveling how life evolved in the ancient past, but are also finding the keys to creating a healthier future.  How does the minuscule chemical cluster in each of our 100 trillion cells accomplish the amazing feat of creating and maintaining our bodies? Frank Ryan, a physician and an evolutionary biologist, describes the complex ways in which the genome operates as a holistic system and not solely through genes coding for proteins—the building blocks of life. Also involved are elaborate switching mechanisms that regulate and control portions of our DNA, as well as the interplay of retroviruses and bacteria.This groundbreaking book explains that we are on the cusp of an amazing era of disease treatment and eradication.

    Coauthored by his son, Francesco, the book answers age-old questions such as: Was there a mitochondrial Eve? Did the first humans originate in Africa or in several spots on the planet at about the same time? How did humans get onto North America, the tip of South America, and Australia?

    Could such an apparently impotent and mindless force really have built the sophisticated molecular devices found throughout nature? The answer, he insists, is no. The only common-sense explanation is intelligent design

    The 7th edition incorporates the latest advances in molecular diagnostics, the Human Genome Project, and much more. More than 240 dynamic illustrations and high-quality photos help you grasp complex concepts more easily. In addition to the book, you will also receive STUDENT CONSULT, enabling you to access the complete contents of the book online, anywhere you go

    In this book, he expands the points he has made, and claims that this debate is not so much about religion versus science, as about the nature of science itself. With infectious enthusiasm, he reveals the mechanics of evolutionary theory, explains how it is rooted in the testable and verifiable scientific method, and why it is therefore a sound explanation of our beginning. He argues passionately that to continue to assert otherwise, to continue to insist that creationism has a place in the science classroom is harmful not only to our children, but to the future of the greater world as well.
