But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making.In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.

    From blurry vision, to crooked teeth, ACLs that tear at alarming rates and spines that seem to spend a lifetime falling apart, it's a curious thing that human beings have beaten the odds as a species. After all, we're the only survivors on our branch of the tree of life. Why is it that human mothers have such a life-endangering experience giving birth? And why are there entire medical specialties for teeth and feet? In this funny, wide-ranging and often surprising book, biologist Alex Bezzerides tells us just where we inherited our adaptable, achy, brilliant bodies in the process of evolution.The book traces the delightfully unexpected answers to these questions and many more:Why do we blink?Why don't our teeth regularly fit in our mouths?Why do women menstruate when so many other mammals don't?Why did humans stand up on two legs in the first place?

    Through a series of entertaining, bite-sized chapters that combine anthropological insight with cutting-edge science, we gain fresh perspectives into our first hominin ancestors and ways to challenge perceptions about the traditional progression of evolution. With Lee as our guide, we discover that we indeed have always been a species of continuous change.

    This new edition has been entirely rewritten to take account of the latest work of historians and scientists. The sequence of chapters has been reconstructed in a way that will help students and general readers to understand the key phases in the development of modern evolutionism. The book's substantial bibliography has been updated to serve as a valuable introduction to the immense literature on this topic.

    Buried there lie answers about the origins of humankind. After a century of investigation, scientists have transformed our understanding about the beginnings of human life. But vital clues still remain hidden. In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies as well as their feats of skill and endurance.The results have been momentous. Scientists have identified more than twenty species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans. They have revealed how early technology, language ability, and artistic endeavour all originated in Africa; and they have shown how small groups of Africans spread out from Africa in an exodus sixty thousand years ago to populate the rest of the world. We have all inherited an African past.

    Beginning with the above questions, she began informally researching every affliction that she encountered in humans to learn whether it happened with animals, too. And usually, it did: dinosaurs suffered from brain cancer, koalas can catch chlamydia, reindeer seek narcotic escape in hallucinogenic mushrooms, stallions self-mutilate, and gorillas experience clinical depression. Natterson-Horowitz and science writer Kathryn Bowers have dubbed this pan-species approach to medicine zoobiquity. Here, they present a revelatory understanding of what animals can teach us about the human body and mind, exploring how animal and human commonality can be used to diagnose, treat, and heal patients of all species.

    It’s so bound up with our deepest feelings that emotional trauma causes it to change shape.Practising cardiologist Sandeep Jauhar beautifully weaves his own experiences with the defining discoveries of the past to tell the story of our most vital organ. He looks at some of the pioneers who risked their careers and their patients’ lives to better understand the heart. People like Daniel Hale Williams, who performed the world’s first documented heart surgery, and Wilson Greatbatch, who accidentally invented the pacemaker.Amid gripping scenes from the operating theatre, Jauhar interweaves stories about the patients he’s treated with the moving tale of his family’s own history of heart problems, from his grandfather’s sudden death in India – an event that sparked his life-long obsession – to the ominous signs of how he himself might die.He also confronts the limits of medical technology and argues that future progress will be determined more by how we choose to live rather than by any device we invent.

    It is one of many awe-inspiring, magical processes that have evolved among the fungi, yet this group remains the least studied and most poorly understood kingdom of organisms. In Mushroom, NicholasMoney offers a vibrant introduction to the world of mushrooms, investigating the science behind these organisms as well as their enduring cultural and imaginative appeal. Beginning with the basics of mushroom biology, Money leads us through a history of mushroom research, painting portraits of thecolorful characters involved in their study--among them, Beatrix Potter, the celebrated author and creator of Peter Rabbit, and Captain Charles McIlvaine, a Civil War veteran who engaged in a dangerous quest to determine the edibility of every mushroom in North America. Money also discusses the usesof mushrooms today, exploring their importance as food and medicine, their use as recreational drugs, and as the cause of horrific poisonings. A cultural, natural, and scientific history in one, Mushroom is a must-read for mycophiles, mushroom gatherers, and nature lovers alike.

    In The Ends of the World, Peter Brannen dives into deep time, exploring Earth’s past dead ends, and in the process, offers us a glimpse of our possible future.Many scientists now believe that the climate shifts of the twenty-first century have analogs in these five extinctions. Using the visible clues these devastations have left behind in the fossil record, The Ends of the World takes us inside “scenes of the crime,” from South Africa to the New York Palisades, to tell the story of each extinction. Brannen examines the fossil record—which is rife with creatures like dragonflies the size of sea gulls and guillotine-mouthed fish—and introduces us to the researchers on the front lines who, using the forensic tools of modern science, are piecing together what really happened at the crime scenes of the Earth’s biggest whodunits.Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave, and casts our future in a completely new light.

    Like when doctors prescribed morphine for crying infants. When snorting skull moss was a cure for a bloody nose. When consuming mail-order tapeworms was a latter-day fad diet. Or when snake oil salesmen peddled strychnine (used in rat poison) as an aphrodisiac in the '60s. Seamlessly combining macabre humor with hard science and compelling storytelling, Quackery is a visually rich and information-packed exploration of history's most outlandish cures, experiments, and scams.A humorous book that delves into some of the wacky but true ways that humans have looked to cure their ills. Leeches, mercury, strychnine, and lobotomies are a few of the topics that explore the lengths society has gone in the search for health.

    From biblical plagues, to the AIDS crisis, to supergerms of the future, this updated and revised edition of the original covers the whole gamut of diseases that have threatened humanity since its origins.It also includes a new chapter on the history of bioterrorism and the deplorable role it has played and is likely to play in the phenomenal diversity of diseases.

    Although several books have been written about this surprising event, known as the Cambrian explosion, none has explained why it occurred. Indeed, none was able to. Here, for the first time, Oxford zoologist Andrew Parker reveals his theory of this great flourishing of life. Parker's controversial but increasingly accepted "Light Switch Theory" holds that it was the development of vision in primitive animals that caused the explosion. Drawing on evidence not just from biology, but also from geology, physics, chemistry, history, and art, In the Blink of an Eye is the fascinating account of a young scientist's intellectual journey, and a celebration of the scientific method.

    Cavalli-Sforza and others have answered this question—anticipated by Darwin—with a decisive yes. Genes, Peoples, and Languages comprises five lectures that serve as a summation of the author's work over several decades, the goal of which has been nothing less than tracking the past hundred thousand years of human evolution.Cavalli-Sforza raises questions that have serious political, social, and scientific import: When and where did we evolve? How have human societies spread across the continents? How have cultural innovations affected the growth and spread of populations? What is the connection between genes and languages? Always provocative and often astonishing, Cavalli-Sforza explains why there is no genetic basis for racial classification.

    The 10,000 Year Explosion: How Civilization Accelerated Human Evolution

    The media seized hold of the story and, in the process, helped to launch one of the most devastating health scares ever. In the years to come Wakefield would be revealed as a profiteer in league with class-action lawyers, and he would eventually lose his medical license. Meanwhile, one study after another failed to find any link between childhood vaccines and autism. Yet the myth that vaccines somehow cause developmental disorders lives on. Despite the lack of corroborating evidence, it has been popularized by media personalities such as Oprah Winfrey and Jenny McCarthy and legitimized by journalists who claim that they are just being fair to “both sides” of an issue about which there is little debate. Meanwhile, millions of dollars have been diverted from potential breakthroughs in autism research; families have spent their savings on ineffective “miracle cures"; and declining vaccination rates have led to outbreaks of deadly illnesses like Hib, measles, and whooping cough. Most tragic of all is the increasing number of children dying from vaccine-preventable diseases. In The Panic Virus Seth Mnookin draws on interviews with parents, public-health advocates, scientists, and anti-vaccine activists to tackle a fundamental question: How do we decide what the truth is? The fascinating answer helps explain everything from the persistence of conspiracy theories about 9/11 to the appeal of talk-show hosts who demand that President Obama “prove” he was born in America. The Panic Virus is the ultimate cautionary tale for our time.
