The prolonged encounter between the Cro-Magnons and the archaic Neanderthals and between 45,000 and 30,000 years ago was one of the defining moments of history. The Neanderthals survived for some 15,000 years in the face of the newcomers, but were finally pushed aside by the Cro-Magnons' vastly superior intellectual abilities and cutting-edge technologies, which allowed them to thrive in the intensely challenging climate of the Ice Age.What do we know about this remarkable takeover? Who were the first modern Europeans and what were they like? How did they manage to thrive in such an extreme environment? And what legacy did they leave behind them after the cold millennia? The age of the Cro-Magnons lasted some 30,000 years?longer than all of recorded history. Cro-Magnon is the story of a little known, yet seminal, chapter of human experience.

    Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    And despite centuries of study there is always more to know. In 2008, paleontologist John A. Long and a team of researchers revealed their discovery of a placoderm fish fossil, known as “the mother fish,” which at 380 million years old revealed the oldest vertebrate embryo—the earliest known example of internal fertilization. As Long explains, this find led to the reexamination of countless fish fossils and the discovery of previously undetected embryos. As a result, placoderms are now considered to be the first species to have had intimate sexual reproduction or sex as we know it—sort of. Inspired by this incredible find, Long began a quest to uncover the paleontological and evolutionary history of copulation and insemination. In The Dawn of the Deed, he takes readers on an entertaining and lively tour through the sex lives of ancient fish and exposes the unusual mating habits of arthropods, tortoises, and even a well-endowed (16.5 inches!) Argentine Duck. Long discusses these significant discoveries alongside what we know about reproductive biology and evolutionary theory, using the fossil record to provide a provocative account of prehistoric sex. The Dawn of the Deed also explores fascinating revelations about animal reproduction, from homosexual penguins to monogamous seahorses to the difficulties of dinosaur romance and how sexual organs in ancient shark-like fishes actually relate to our own sexual anatomy. The Dawn of the Deed is Long’s own story of what it’s like to be a part of a discovery that rewrites evolutionary history as well as an absolutely rollicking guide to sex throughout the ages in the animal kingdom. It’s natural history with a naughty wink.

    She introduces us to renowned futurists like Stewart Brand and scientists like George Church, who are harnessing the powers of CRISPR gene editing in the hopes of “reviving” extinct passenger pigeons, woolly mammoths, and heath hens. She speaks with Nikita Zimov, who together with his eclectic father Sergey, is creating Siberia’s Pleistocene Park—a daring attempt to rebuild the mammoth’s ancient ecosystem in order to save earth from climate apocalypse. Through interviews with these and other thought leaders, Wray reveals the many incredible opportunities for research and conservation made possible by this emerging new field.But we also hear from more cautionary voices, like those of researcher and award-winning author Beth Shapiro (How to Clone a Woolly Mammoth) and extinction philosopher Thomas van Dooren. Writing with passion and perspective, Wray delves into the larger questions that come with this incredible new science, reminding us that de-extinction could bring just as many dangers as it does possibilities. What happens, for example, when we bring an “unextinct” creature back into the wild? How can we care for these strange animals and ensure their comfort and safety—not to mention our own? And what does de-extinction mean for those species that are currently endangered? Is it really ethical to bring back an extinct passenger pigeon, for example, when countless other birds today will face the same fate?By unpacking the many biological, technological, ethical, environmental, and legal questions raised by this fascinating new field, Wray offers a captivating look at the best and worst of resurrection science.

    Bursting with all the suspense and intrigue of a fast paced adventure novel, here is Johanson’s lively account of the extraordinary discovery of “Lucy.” By expounding the controversial change Lucy makes in our view of human origins, Johanson provides a vivid, behind-the-scenes account of the history of pealeoanthropology and the colorful, eccentric characters who were and are a part of it. Never before have the mystery and intricacy of our origins been so clearly and compellingly explained as in this astonighing and dramatic book.

    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).

    Members of the phylum Mollusca are among the most ancient animals on the planet. Their shells provide homes for other animals, and across the ages, people have used shells not only as trinkets but also as a form of money, and as powerful symbols of sex and death, prestige and war.The science and natural history of shells are woven into a compelling narrative, revealing their cultural importance and the ways they have been used by humans over the millennia. (Seashells have even been tapped as a source of mind-bending drugs.) Marine biologist Helen Scales shows how seashells have been sculpted by the fundamental rules of mathematics and evolution; how they gave us color, gems, food, and new medicines.After surviving multiple mass extinctions millions of years ago, molluscs and their shells still face an onslaught of anthropogenic challenges, including climate change and corrosive oceans. But rather than dwelling on all that is lost, Scales emphasizes that seashells offer an accessible way to reconnect people with nature, helping to bridge the gap between ourselves and the living world. Spirals in Time: The Secret Life and Curious Afterlife of Seashells shows why nature matters, and reveals the hidden wonders that you can hold in the palm of your hand.

    But was it a savage sheep killer or a shy, fussy, nocturnal feeder? And did it really drink its victims' blood? Once reviled, feared and slaughtered by government decree, the myth of the Tasmanian Tiger continues to grow. So treasured is it now, the Tasmanian Tiger has become the official logo of the island that wiped it out and a symbol of the conservation movement world-wide.A number of Australian species have miraculously reappeared after being labelled as extinct. Perhaps the Tiger is still with us. And if it's not, can it be brought back by cloning?

    bataar bones he was impressed. The enormous skull and teeth betrayed the apex predators close relation to the storied Tyrannosaurus rex, the most famous animal that ever lived. Prokopi's obsession with fossils had begun decades earlier, when he was a Florida boy scouring for shark teeth and Ice Age remnants, and it had continued as he built a thriving business hunting, preparing, and selling specimens to avid collectors and private museums around the world. To scientists' fury and dismay, there was big money to be made in certain corners of the fossil trade. Prokopi didn't consider himself merely a businessman, though. He also thought of himself as a vital part of paleontology--as one of the lesser-known artistic links in bringing prehistoric creatures back to life--and saw nothing wrong with turning a profit in the process. Bone hunting was expensive, risky, controversial work, and he increasingly needed bigger "scores." By the time he acquired a largely complete skeleton of T. bataar and restored it in his workshop, he was highly leveraged and drawing quiet scorn from peers who worried that by bringing such a big, beautiful Mongolian dinosaur to market he would tarnish the entire trade. Presenting the skeleton for sale at a major auction house in New York City, he was relieved to see the bidding start at nearly $1 million---only to fall apart when the president of Mongolia unexpectedly stepped in to question the specimen's origins and demand its return. An international custody battle ensued, shining new light on the black market for dinosaur fossils, the angst of scientists who fear for their field, and the precarious political tensions in post-Communist Mongolia. The Prokopi case, unprecedented in American jurisprudence, continues to reverberate throughout the intersecting worlds of paleontology, museums, art, and geopolitics.

    But evolutionary biologists also point out many examples of contingency, cases where the tiniest change--a random mutation or an ancient butterfly sneeze--caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary freaks? And what does that say about life on other planets?Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be.Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

    Situating these fascinating animals in a broad ecological and evolutionary context, leading dinosaur expert Scott D. Sampson fills us in on the exhilarating discoveries of the past twenty-five years, the most active period in the history of dinosaur paleontology, during which more “new” species were named than in all prior history. With these discoveries—and the most recent controversies—in mind, Sampson reconstructs the odyssey of the dinosaurs from their humble origins on the supercontinent Pangaea, to their reign as the largest animals the planet has ever known, and finally to their abrupt demise. Much more than the story of who ate whom way back when, Dinosaur Odyssey places dinosaurs in an expansive web of relationships with other organisms and demonstrates how they provide a powerful lens through which to observe the entire natural world. Addressing topics such as extinction, global warming, and energy flow, Dinosaur Odyssey finds that the dinosaurs' story is, in fact, a major chapter in our own story.

    Hazen writes of how the co-evolution of the geosphere and biosphere—of rocks and living matter—has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.With an astrobiologist’s imagination, a historian’s perspective, and a naturalist’s passion for the ground beneath our feet, Hazen explains how changes on an atomic level translate into dramatic shifts in Earth’s makeup over its 4.567 billion year existence. He calls upon a flurry of recent discoveries to portray our planet’s many iterations in vivid detail. Through his theory of “co-evolution,” we learn how reactions between organic molecules and rock crystals may have generated Earth’s first organisms, which in turn are responsible for more than two-thirds of the mineral varieties on the planet.The Story of Earth is also the story of the pioneering men and women behind the sciences. Readers will meet black-market meteorite hawkers of the Sahara Desert, the gun-toting Feds who guarded the Apollo missions’ lunar dust, and the World War II Navy officer whose super-pressurized “bomb”—recycled from military hardware—first simulated the molten rock of Earth’s mantle. As a mentor to a new generation of scientists, Hazen introduces the intrepid young explorers whose dispatches from Earth’s harshest landscapes will revolutionize geology.

    Legendary marine scientist Sylvia Earle portrays a planet teetering on the brink of irreversible environmental crisis.In recent decades we’ve learned more about the ocean than in all previous human history combined. But, even as our knowledge has exploded, so too has our power to upset the delicate balance of this complex organism. Modern overexploitation has driven many species to the verge of extinction, from tiny but indispensable biota to magnificent creatures like tuna, swordfish, and great whales. Since the mid-20th century about half our coral reefs have died or suffered sharp decline; hundreds of oxygen-deprived "dead zones" blight our coastal waters; and toxic pollutants afflict every level of the food chain.Fortunately, there is reason for hope, but what we do—or fail to do—in the next ten years may well resonate for the next ten thousand. The ultimate goal, Earle argues passionately and persuasively, is to find responsible, renewable strategies that safeguard the natural systems that sustain us. The first step is to understand and act upon the wise message of this accessible, insightful, and compelling book.

    Told through an examination of animal and plant life today - with occasional juxtapositions of extinct fossil forms to reveal the origin of living creatures - "Life on Earth" is an astonishing pageant of life, with a cast of characters drawn from the whole range of living animals the world over. Attenborough's perceptive, dynamic approach to the evolution of some four million species of living organisms that populate the planet is to trace the most significant thread in the history of each major group. He then proceeds to explain from the evidence of living representatives and fossil remains why certain animals adapted and survived, evolved to more complex and "higher" forms of life, while others, by some inherent limitation imposed by their physiology or structure, failed and became extinct. "Life on Earth" is a book of wonders. A model of clarity and ease as a guide, Attenborough takes the reader around the world with him into jungles where orchids have petals that "impersonate" wasps to attract pollinating insects; to Australia, where honeypot ants force feed nectar to workers of a special caste, then hang them up by their forelegs like living storage jars; to remote mountains in Japan where little monkeys called macaques have learned to combat the winter snows by bathing in hot volcanic springs.
