Probes the mystery of the construction and significance of the Great Pyramid of Cheops, suggesting that it enshrines the scientific data of an advanced Egyptian civilization.

    Mainstream science--as well as religious and cultural institutions--has maintained that men and women evolved in families in which a man's possessions and protection were exchanged for a woman's fertility and fidelity. But this narrative is collapsing. Fewer and fewer couples are getting married, and divorce rates keep climbing as adultery and flagging libido drag down even seemingly solid marriages.How can reality be reconciled with the accepted narrative? It can't be, according to renegade thinkers Christopher Ryan and Cacilda Jethá. While debunking almost everything we "know" about sex, they offer a bold alternative explanation in this provocative and brilliant book.Ryan and Jethá's central contention is that human beings evolved in egalitarian groups that shared food, child care, and, often, sexual partners. Weaving together convergent, frequently overlooked evidence from anthropology, archaeology, primatology, anatomy, and psychosexuality, the authors show how far from human nature monogamy really is. Human beings everywhere and in every era have confronted the same familiar, intimate situations in surprisingly different ways. The authors expose the ancient roots of human sexuality while pointing toward a more optimistic future illuminated by our innate capacities for love, cooperation, and generosity.With intelligence, humor, and wonder, Ryan and Jethá show how our promiscuous past haunts our struggles over monogamy, sexual orientation, and family dynamics. They explore why long-term fidelity can be so difficult for so many; why sexual passion tends to fade even as love deepens; why many middle-aged men risk everything for transient affairs with younger women; why homosexuality persists in the face of standard evolutionary logic; and what the human body reveals about the prehistoric origins of modern sexuality.In the tradition of the best historical and scientific writing, Sex at Dawn unapologetically upends unwarranted assumptions and unfounded conclusions while offering a revolutionary understanding of why we live and love as we do.

    It turns out that the Neanderthals’ behavior was surprisingly modern: they buried the dead, cared for the sick, hunted large animals in their prime, harvested seafood, and communicated with spoken language. Meanwhile, advances in DNA technologies are compelling us to reassess the Neanderthals’ place in our own past.For hundreds of thousands of years, Neanderthals evolved in Europe parallel to Homo sapiens evolving in Africa, and, when both species made their first forays into Asia, the Neanderthals may even have had the upper hand. In this important volume, Dimitra Papagianni and Michael A. Morse compile the first full chronological narrative of the Neanderthals’ dramatic existence—from their evolution in Europe to their expansion to Siberia, their subsequent extinction, and ultimately their revival in popular novels, cartoons, cult movies, and television commercials.

    In How to Clone a Mammoth, Beth Shapiro, evolutionary biologist and pioneer in "ancient DNA" research, walks readers through the astonishing and controversial process of de-extinction. From deciding which species should be restored, to sequencing their genomes, to anticipating how revived populations might be overseen in the wild, Shapiro vividly explores the extraordinary cutting-edge science that is being used--today--to resurrect the past. Journeying to far-flung Siberian locales in search of ice age bones and delving into her own research--as well as those of fellow experts such as Svante Paabo, George Church, and Craig Venter--Shapiro considers de-extinction's practical benefits and ethical challenges. Would de-extinction change the way we live? Is this really cloning? What are the costs and risks? And what is the ultimate goal?Using DNA collected from remains as a genetic blueprint, scientists aim to engineer extinct traits--traits that evolved by natural selection over thousands of years--into living organisms. But rather than viewing de-extinction as a way to restore one particular species, Shapiro argues that the overarching goal should be the revitalization and stabilization of contemporary ecosystems. For example, elephants with genes modified to express mammoth traits could expand into the Arctic, re-establishing lost productivity to the tundra ecosystem.Looking at the very real and compelling science behind an idea once seen as science fiction, How to Clone a Mammoth demonstrates how de-extinction will redefine conservation's future.

    As part of the healing process, she decided to use DNA research to learn more about herself, her family, and the interconnectedness of society. She went deep in search of her genealogy, having her DNA sequenced and tested, and effectively becoming an experimental subject. Remarkably, she was able to trace the path of her ancestors through recorded history and into prehistory. Through the course of her research, she met dozens of scientists working in genetic research. The narrative travels the length and breadth of Europe, from the Neanderthals of central Germany to the Cro-Magnon in France. Bojs visited the ancient caves, realizing that her direct ancestors must have been living in the area when the cave art was painted. A second DNA analysis later revealed she has Sami (i.e. Lapp) genetic material in her genome, and there were further revelations about her hunter-gatherer, Bronze-Age, and Iron-Age relatives, including the Vikings. This fresh, first-person exploration of genes and genetics goes well beyond personal genealogy and reveals much about the shared history of European peoples.

    In this explosive new work of archaeological detection, bestselling author and renowned explorer Graham Hancock embarks on a captivating underwater voyage to find the ruins of a mythical lost civilization hidden for thousands of years beneath the world’s oceans. Guided by cutting-edge science, innovative computer-mapping techniques, and the latest archaeological scholarship, Hancock examines the mystery at the end of the last Ice Age and delivers astonishing revelations that challenge our long-held views about the existence of a sunken universe built on the ocean floor.Filled with exhilarating accounts of his own participation in dives off the coast of Japan, as well as in the Mediterranean, the Atlantic, and the Arabian Sea, we watch as Hancock discovers underwater ruins exactly where the ancient myths say they should be—submerged kingdoms that archaeologists never thought existed. You will be captivated by Underworld, a provocative book that is both a compelling piece of hard evidence for a fascinating forgotten episode in human history and a completely new explanation for the origins of civilization as we know it.

    Their memories stretch back across the million-year cycles of the ice sheets.Their stories tell of the making of the world. And as the millenia have passed, their legends have served them well.And a thousand years from now, on a different world, they will be the difference between life and death, between extinction and a future as long as the past.This new edition collects three of Stephen Baxter's early books together for the first time.

    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.

    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.

    Never kill a human unprovoked. Never allow a mixed-blood wolf to live. At least that's what the wolves of the Wide Valley believe. Until a young wolf dares to break the rules--and forever alters the relationship between wolves and the humans who share their world.This is the story of such a wolf. Born of a forbidden mixed-blood litter and an outcast after her mother is banished, Kaala is determined to earn a place in the Swift River pack. But her world is turned upside down when she saves a human girl from drowning. Risking expulsion from their pack and exile from the Wide Valley, Kaala and her young packmates begin to hunt with the humans and thus discover the long-hidden bond between the two clans. But when war between wolves and humans threatens, Kaala learns the lies behind the wolf's promise. Lies that force her to choose between safety for herself and her friends and the survival of her pack--and perhaps of all wolf- and humankind. Set 14,000 years ago, Promise of the Wolves takes us to a land where time is counted in phases of the moon, distance is measured in wolflengths, and direction by the scent of the nearest trail. Years of research into the world of wolves combines with mythical tale-telling to present a fantastical adventure set in a world filled with lore.

    Civilization, we are told, could be achieved only by sacrificing those original freedoms or, alternatively, by taming our baser instincts. David Graeber and David Wengrow show how such theories first emerged in the eighteenth century as a conservative reaction to powerful critiques of European society posed by Indigenous observers and intellectuals. Revisiting this encounter has startling implications for how we make sense of human history today, including the origins of farming, property, cities, democracy, slavery, and civilization itself.Drawing on pathbreaking research in archaeology and anthropology, the authors show how history becomes a far more interesting place once we learn to throw off our conceptual shackles and perceive what's really there. If humans did not spend 95 percent of their evolutionary past in tiny bands of hunter-gatherers, what were they doing all that time? If agriculture, and cities, did not mean a plunge into hierarchy and domination, then what kinds of social and economic organization did they lead to? The answers are often unexpected, and suggest that the course of human history may be less set in stone, and more full of playful, hopeful possibilities, than we tend to assume.The Dawn of Everything fundamentally transforms our understanding of the human past and offers a path toward imagining new forms of freedom, new ways of organizing society. This is a monumental book of formidable intellectual range, animated by curiosity, moral vision, and a faith in the power of direct action.

    It takes another three billion years of evolving life forms until it finally happens, a primate super species emerges: mankind. In conjunction with History Channel's hit television series by the same name, Mankind is a sweeping history of humans from the birth of the Earth and hunting antelope in Africa's Rift Valley to the present day with the completion of the Genome project and the birth of the seven billionth human. Like a Hollywood action movie, Mankind is a fast-moving, adventurous history of key events from each major historical epoch that directly affect us today such as the invention of iron, the beginning of Buddhism, the crucifixion of Jesus, the fall of Rome, the invention of the printing press, the Industrial Revolution, and the invention of the computer. With more than 300 color photographs and maps, Mankind is not only a visual overview of the broad story of civilization, but it also includes illustrated pop-out sidebars explaining distinctions between science and history, such as why there is 700 times more iron than bronze buried in the earth, why pepper is the only food we can taste with our skin, and how a wobble in the earth's axis helped bring down the Egyptian Empire. This is the most exciting and entertaining history of mankind ever produced.

    But when one of her brothers goes hunting and never returns, the fragile balance of life is upset. Half-starved and maddened with grief, Alaia's mother follows her visions and goes in search of her lost son. Then a stranger from a rival tribe appears on their hearth seeking shelter. Are his stories of a great wave and a people perished really to be believed? What else could drive a man to travel alone between tribes in the depths of winter?Hopes of resolution come when Alaia's mother returns home as a Go-Between, one able to commune with the spirits. But as all the Auk people come together for their annual Gathering Night, who there will listen to the voice of a woman?The Gathering Night is a story of conflict, loss, love, adventure and devastating natural disasters. This utterly enchanting pre-historical novel is set deep in our stone-age past, but resonates as a parable of our troubled planet 8000 years on.

    Maybe it's made of silicon! Maybe it has wheels! Or maybe it doesn't. In The Equations of Life, biologist Charles S. Cockell makes the forceful argument that the laws of physics narrowly constrain how life can evolve, making evolution's outcomes predictable. If we were to find on a distant planet something very much like a lady bug eating something like an aphid, we shouldn't be surprised. The forms of life are guided by a limited set of rules, and as a result, there is a narrow set of solutions to the challenges of existence.A remarkable scientific contribution breathing new life into Darwin's theory of evolution, The Equations of Life makes a radical argument about what life can -- and can't -- be.

    Entire cities are replaced by primeval forests. Prehistoric monsters stalk modern city streets, hunting for human prey.While ordinary men and women struggle to survive in this strange new world, the president and his advisers search for a way to undo the catastrophe. But the solution may be more devastating than the dinosaurs....
