    Radiometric dating of nearby rocks indicated the skeleton, classified as Ardipithecus ramidus, was 4.4 million years old, more than a million years older than "Lucy," then the oldest known human ancestor. The findings challenged many assumptions about human evolution--how we started walking upright, how we evolved our nimble hands, and, most significantly, whether we were descended from an ancestor that resembled today's chimpanzee--and repudiated a half-century of paleoanthropological orthodoxy.Fossil Men is the first full-length exploration of Ardi, the fossil men who found her, and her impact on what we know about the origins of the human species. It is a scientific detective story played out in anatomy and the natural history of the human body. Kermit Pattison brings into focus a cast of eccentric, obsessive scientists, including one of the world's greatest fossil hunters, Tim White--an exacting and unforgiving fossil hunter whose virtuoso skills in the field were matched only by his propensity for making enemies; Gen Suwa, a Japanese savant who sometimes didn't bother going home at night to devote more hours to science; Owen Lovejoy, a onetime creationist-turned-paleoanthropologist; Berhane Asfaw, who survived imprisonment and torture to become Ethiopia's most senior paleoanthropologist and who fought for African scientists to gain equal footing in the study of human origins; and the Leakeys, for decades the most famous family in paloanthropology.An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa and a nation caught in a brutal civil war, to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must read for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.

    Two hundred million years ago most of Washington consisted of two large islands, each one a scrap of continent, lying somewhere in the vastness of the Pacific Ocean. One after the other they docked onto the North American continent, each adding its distinctive bit to the complex geologic and geographic mosaic of western North America.

    Biologists have been trying to solve the mystery of how organisms have the ability to migrate and orient with such precision—especially since our own adventurous ancestors spread across the world without maps or instruments. O'Connor goes to the Arctic, the Australian bush, and the South Pacific to talk to masters of their environment who seek to preserve their traditions at a time when anyone can use a GPS to navigate.O'Connor explores the neurological basis of spatial orientation within the hippocampus. Without it, people inhabit a dream state, becoming amnesiacs incapable of finding their way, recalling the past, or imagining the future. Studies have shown that the more we exercise our cognitive mapping skills, the greater the grey matter and health of our hippocampus. O'Connor talks to scientists studying how atrophy in the hippocampus is associated with afflictions such as impaired memory, dementia, Alzheimer's Disease, depression, and PTSD.Wayfinding is a captivating book that charts how our species' profound capacity for exploration, memory, and storytelling results in topophilia, the love of place.

    Cameron Webb’s brief but biting assault on the wide spectrum of religiosity that dominates 21st century America, from the hateful and anti-intellectual dogma of the Christian Right to the whitewashed progressivism of religious moderates. It is also a fascinating and humbling journey into the heart of the universe's most mind-numbing wonders.Drawing on recent insights from cosmology and evolution, Despicable Meme paints a vivid portrait of a cosmos unlike anything ever imagined by the provincial, human-centered faiths of the past – a universe of countless worlds spread across unfathomable distances and times, and where, on at least one of those worlds, the slow march of time would combine with the purposeless mechanisms of chemistry and physics to create a being capable of believing that he alone is the reason for it all.With piercing intelligence and candor, Despicable Meme exposes the folly of that conceit and dispenses with the widespread but utterly improbable notion of a personal creator. But it saves its harshest criticism for the vapid accommodationism of religious liberals, those who unknowingly or uncaringly give cover to the misogynistic, racist, homophobic paranoia of the fanatics by refusing to condemn, or quietly tolerating, the outlandish and immoral doctrines that lie festering at the center of their own “moderate” faiths.Despicable Meme is not only a blistering condemnation of radical fundamentalism, it is an impassioned appeal to the rest of us to once and for all abandon the superstitions of the religion we were raised in and embrace the beauty of an endlessly wondrous, but godless, universe.Show less

    Because of his studies of the Eskimos, his discoveries of land, the application of new ideas and new methods of exploration, Stefansson was considered the foremost polar explorer of his day, and one of the few great explorers of all time. During a period of three or four years Mr. Stefansson has produced a creditable list of books about the Arctic. In some respects his service in publishing the results of his Northern studies has differed from that of earlier explorers. He has challenged our preconceptions about the Arctic. “Hunters of the Great North” gives details of Northern life such as have doubtless come within the experience of all Arctic explorers, but which are new to the average American reader. In short, it is an elementary text-book of the Arctic. Stefansson lived among the Eskimos of the Mackenzie River, studying their language and adopting their mode of life, and spending ten winters and thirteen summers in the polar regions. Among Stefannson's most famous discovery was that of a race of blond Eskimo on Coronation Gulf. Stefansson writes: "In the present book I have tried by means of diaries and memory to go back to the vivid impressions of my first year among the Eskimos for the story of what I saw and heard." In describing his confrontation with a polar bear, Stefansson writes: “I heard behind me a noise like the spitting of a cat or the hiss of a goose. I looked back and saw, about twenty feet away and almost above me, a polar bear. I had overestimated the bear's distance from shore, and had passed the spot where he lay. From his eye and attitude, as well as the story his trail told afterward there was no doubting his intentions: the hiss was merely his way of saying, "Watch me do it!" Or at least that is how I interpreted it; possibly the motive was chivalry, and the hiss was his way of saying Garde!” Contents I. PREPARATIONS FOR A LIFEWORK OF EXPLORATION II.

    Probably most or even all of the above. The story of our home planet and the organisms spread across its surface is far more spectacular than any Hollywood blockbuster, filled with enough plot twists to rival a bestselling thriller. But only recently have we begun to piece together the whole mystery into a coherent narrative. Drawing on his decades of field research and up-to-the-minute understanding of the latest science, renowned geologist Andrew H. Knoll delivers a rigorous yet accessible biography of Earth, charting our home planet's epic 4.6 billion-year story. Placing twenty first-century climate change in deep context, A Brief History of Earth is an indispensable look at where we’ve been and where we’re going.Features original illustrations depicting Earth history and nearly 50 figures (maps, tables, photographs, graphs).

    In Europe: A Natural History, world-renowned scientist, explorer, and conservationist Tim Flannery applies the eloquent interdisciplinary approach he used in his ecological histories of Australia and North America to the story of Europe. He begins 100 million years ago, when the continents of Asia, North America, and Africa interacted to create an island archipelago that would later become the Europe we know today. It was on these ancient tropical lands that the first distinctly European organisms evolved. Flannery teaches us about Europe's midwife toad, which has endured since the continent's beginning, while elephants, crocodiles, and giant sharks have come and gone. He explores the monumental changes wrought by the devastating comet strike and shows how rapid atmospheric shifts transformed the European archipelago into a single landmass during the Eocene.As the story moves through millions of years of evolutionary history, Flannery eventually turns to our own species, describing the immense impact humans had on the continent's flora and fauna--within 30,000 years of our arrival in Europe, the woolly rhino, the cave bear, and the giant elk, among others, would disappear completely. The story continues right up to the present, as Flannery describes Europe's leading role in wildlife restoration, and then looks ahead to ponder the continent's future: with advancements in gene editing technology, European scientists are working to recreate some of the continent's lost creatures, such as the great ox of Europe's primeval forests and even the woolly mammoth.Written with Flannery's characteristic combination of elegant prose and scientific expertise, Europe: A Natural History narrates the dramatic natural history and dynamic evolution of one of the most influential places on Earth.

    A sensational disappearance that made headlines around the world. A quest for truth that leads to death, madness or disappearance for those who seek to solve it. The Lost City of Z is a blockbuster adventure narrative about what lies beneath the impenetrable jungle canopy of the Amazon.After stumbling upon a hidden trove of diaries, New Yorker writer David Grann set out to solve "the greatest exploration mystery of the 20th century": What happened to the British explorer Percy Fawcett & his quest for the Lost City of Z?In 1925, Fawcett ventured into the Amazon to find an ancient civilization, hoping to make one of the most important discoveries in history. For centuries Europeans believed the world's largest jungle concealed the glittering kingdom of El Dorado. Thousands had died looking for it, leaving many scientists convinced that the Amazon was truly inimical to humans. But Fawcett, whose daring expeditions inspired Conan Doyle's The Lost World, had spent years building his scientific case. Captivating the imagination of millions round the globe, Fawcett embarked with his 21-year-old son, determined to prove that this ancient civilisation--which he dubbed Z--existed. Then his expedition vanished. Fawcett's fate, & the tantalizing clues he left behind about Z, became an obsession for hundreds who followed him into the uncharted wilderness. For decades scientists & adventurers have searched for evidence of Fawcett's party & the lost City of Z. Countless have perished, been captured by tribes or gone mad. As Grann delved ever deeper into the mystery surrounding Fawcett's quest, & the greater mystery of what lies within the Amazon, he found himself, like the generations who preceded him, being irresistibly drawn into the jungle's green hell. His quest for the truth & discoveries about Fawcett's fate & Z form the heart of this complexly enthralling narrative.

    Krause is a pioneer in the revolutionary new science of archaeogenetics, archaeology augmented by revolutionary DNA sequencing technology, which has allowed scientists to uncover a new version of human history reaching back more than 100,000 years. Using this technology to re-examine human bones from the distant past, Krause has been able to map not only the genetic profiles of the dead, but also their ancient journeys.In this concise narrative he tells us their long-forgotten stories of migration and intersection. It's well known that many human populations carry genetic material from Neanderthals; but, as Krause and his colleagues discovered, we also share DNA with a newly uncovered human form, the Denisovans. We know now that a wave of farmers from Anatolia migrated into Europe 8,000 years ago, essentially displacing the dark-skinned, blue-eyed hunter-gatherers who preceded them. The farmer DNA is one of the core genetic components of contemporary Europeans and European Americans. Though the first people to cross into North and South America have long been assumed to be primarily of East Asian descent, we now know that they also share DNA with contemporary Europeans and European Americans. Genetics has an unfortunate history of smuggling in racist ideologies, but our most cutting-edge science tells us that genetic categories in no way reflect national borders.Krause vividly introduces us to prehistoric cultures such as the Aurignacians, innovative artisans who carved animals, people, and even flutes from bird bones more than 40,000 years ago; the Varna, who buried their loved ones with gold long before the Pharaohs of Egypt; and the Gravettians, big-game hunters who were Europe's most successful early settlers until they perished in the ice age. This informed retelling of the human epic confirms that immigration and genetic mingling have always defined our species and that who we are is a question of culture not genetics.

    Therefore, while students still learn the skills necessary to design research, the book emphasizes the quantitative reasoning skills students need to become systematic and critical consumers of information. Examples from a variety of sources capture students' interest, and the innovative pedagogical framework ensures that students will retain and be able to apply what they learn.

    To top it he had speech difficulties and was vague and inattentive. Albert hated the kind of rote learning he was obliged to do in school, memorizing dates and texts. But as he grew older, it became clear that Albert was no ordinary person. 1905 is often termed his 'miracle year', the year he published not one but four entirely new papers, on four completely different topics.

    New features include an enhanced reader-friendly approach, new color illustrations, and a greater emphasis on clinical applications. A new, interactive CD-ROM offers three-dimensional animations of masticatory movements - including tooth contact relationships and temporomandibular joint movements - that bring the text's illustrations to life. Plus, an interactive mock examination mimics the National Board exam for outstanding review and practice.

    The consequences of this gathering may be enormous. In this new ebook, experts Patrick J. Michaels and Paul C. Knappenberger assess the issues sure to drive the debate before, during, and after the Paris meeting.

    An evolutionary perspective forms the foundation of the entire discussion. The book begins with the natural history of the planet, considers portions of the whole in the middle chapters, and ends with another perspective of the entire planet in the concluding chapter. Its unique organization of focusing only on several key concepts in each chapter sets it apart from the competition. .
