Dunn illuminates the nuanced, often imperceptible relationships that exist between homo sapiens and other species, relationships that underpin humanity’s ability to thrive and prosper in every circumstance.

    On the one hand, we struggle to survive on our own in the wild, often unable to solve basic problems, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced innovative technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into environments across the globe. What has enabled us to dominate such a vast range of environments, more than any other species? As this book shows, the secret of our success lies not in our innate intelligence, but in our collective brains--in the ability of human groups to socially interconnect and learn from one another.Drawing insights from lost European explorers, clever chimpanzees, hunter-gatherers, neuroscientists, ancient bones, and the human genome, Joseph Henrich demonstrates how our collective brains have propelled our species' genetic evolution and shaped our biology. Our early capacities for learning from others produced many innovations, such as fire, cooking, water containers, plant knowledge, and projectile weapons, which in turn drove the expansion of our brains and altered our physiology, anatomy, and psychology in crucial ways. Further on, some collective brains generated and recombined powerful concepts, such as the lever, wheel, screw, and writing. Henrich shows how our genetics and biology are inextricably interwoven with cultural evolution, and that this particular culture-gene interaction has propelled our species on an extraordinary evolutionary trajectory.Tracking clues from our ancient past to the present, "The Secret of Our Success" explores how our cultural and social natures produce a collective intelligence that explains both our species' immense success and our human uniqueness.

    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.

    Its presence in nature was dismissed as a desperate response to starvation or other life-threatening circumstances, and few spent time studying it. A taboo subject in our culture, the behavior was portrayed mostly through horror movies or tabloids sensationalizing the crimes of real-life flesh-eaters. But the true nature of cannibalism--the role it plays in evolution as well as human history--is even more intriguing (and more normal) than the misconceptions we've come to accept as fact. In Cannibalism: A Perfectly Natural History, zoologist Bill Schutt sets the record straight, debunking common myths and investigating our new understanding of cannibalism's role in biology, anthropology, and history in the most fascinating account yet written on this complex topic. Schutt takes readers from Arizona's Chiricahua Mountains, where he wades through ponds full of tadpoles devouring their siblings, to the Sierra Nevadas, where he joins researchers who are shedding new light on what happened to the Donner Party--the most infamous episode of cannibalism in American history. He even meets with an expert on the preparation and consumption of human placenta (and, yes, it goes well with Chianti). Bringing together the latest cutting-edge science, Schutt answers questions such as why some amphibians consume their mother's skin; why certain insects bite the heads off their partners after sex; why, up until the end of the twentieth century, Europeans regularly ate human body parts as medical curatives; and how cannibalism might be linked to the extinction of the Neanderthals. He takes us into the future as well, investigating whether, as climate change causes famine, disease, and overcrowding, we may see more outbreaks of cannibalism in many more species--including our own.Cannibalism places a perfectly natural occurrence into a vital new context and invites us to explore why it both enthralls and repels us.

    This may seem hard to accept, but, as Harari explains in his trademark style—thorough, yet riveting—famine, plague and war have been transformed from incomprehensible and uncontrollable forces of nature into manageable challenges. For the first time ever, more people die from eating too much than from eating too little; more people die from old age than from infectious diseases; and more people commit suicide than are killed by soldiers, terrorists and criminals put together. The average American is a thousand times more likely to die from binging at McDonalds than from being blown up by Al Qaeda.What then will replace famine, plague, and war at the top of the human agenda? As the self-made gods of planet earth, what destinies will we set ourselves, and which quests will we undertake? Homo Deus explores the projects, dreams and nightmares that will shape the twenty-first century—from overcoming death to creating artificial life. It asks the fundamental questions: Where do we go from here? And how will we protect this fragile world from our own destructive powers? This is the next stage of evolution. This is Homo Deus.With the same insight and clarity that made Sapiens an international hit and a New York Times bestseller, Harari maps out our future.

    Chance and Necessity is a philosophical statement whose intention is to sweep away as both false and dangerous the animist conception of man that has dominated virtually all Western worldviews from primitive cultures to those of dialectical materialists. He bases his argument on the evidence of modern biology, which indisputably shows, that man is the product of chance genetic mutation. With the unrelenting logic of the scientist, he draws upon what we now know (and can theorize) of genetic structure to suggest an new way of looking at ourselves. He argues that objective scientific knowledge, the only reliable knowledge, denies the concepts of destiny or evolutionary purpose that underlie traditional philosophies. He contends that the persistence of those concepts is responsible for the intensifying schizophrenia of a world that accepts, and lives by, the fruits of science while refusing to face its moral implications. Dismissing as "animist" not only Plato, Hegel, Bergson and Teilhard de Chardin but Spencer and Marx as well, he calls for a new ethic that will recognize the distinction between objective knowledge and the realm of values--an ethic of knowledge that can, perhaps, save us from our deepening spiritual malaise, from the new age of darkness he sees coming.PrefaceOf strange objects Vitalisms and animisms Maxwell's demons Microscopic cyberneticsMolecular ontogenesis Invariance and perturbationsEvolution The frontiers The kingdom and the darknessAppendixes

    Why, if the human instinct to survive and reproduce is “selfish,” do people engage in self-sacrifice, and even develop ideas like virtue and shame to justify that altruism? Many theories have been put forth, some emphasizing the role of nepotism, others emphasizing the advantages of reciprocation or group selection effects. But evolutionary anthropologist Christopher Boehm finds existing explanations lacking, and in Moral Origins, he offers an elegant new theory.Tracing the development of altruism and group social control over 6 million years, Boehm argues that our moral sense is a sophisticated defense mechanism that enables individuals to survive and thrive in groups. One of the biggest risks of group living is the possibility of being punished for our misdeeds by those around us. Bullies, thieves, free-riders, and especially psychopaths—those who make it difficult for others to go about their lives—are the most likely to suffer this fate. Getting by requires getting along, and this social type of selection, Boehm shows, singles out altruists for survival. This selection pressure has been unique in shaping human nature, and it bred the first stirrings of conscience in the human species. Ultimately, it led to the fully developed sense of virtue and shame that we know today.A groundbreaking exploration of the evolution of human generosity and cooperation, Moral Origins offers profound insight into humanity’s moral past—and how it might shape our moral future.

    If...we could ask and it could reply, it would give up to us the most intimate secrets of life. -from Chapter II Anticipating not only modern scientific theories of psychology but also those of cosmology, this astonishing book sets out a impressive goal for itself: to reconcile human biology with a theory of consciousness. First published in France in 1907, and translated into English in 1911, this work of wonder was esteemed at the time in scientific circles and in the popular culture alike for its profound explorations of perception and memory and its surprising conclusions about the nature and value of art. Contending that intuition is deeper than intellect and that the real consequence of evolution is a mental freedom to grow, to change, to seek and create novelty, Bergson reinvigorated the theory of evolution by refusing to see it as merely mechanistic. His expansion on Darwin remains one of the most original and important philosophical arguments for a scientific inquiry still under fire today. French philosopher HENRI BERGSON (1859-1941) was born in Paris. Among his works are Matter and Memory (1896), An Introduction to Metaphysics (1903), and The Two Sources of Morality and Religion (1932). He was awarded the Nobel Prize for Literature in 1927.

    With the help of a beguiling mix of illustrated optical illusions and puzzles, anecdotes, mathematics, and philosophy, Ings reveals age-old mysteries from how humans perceive color to Woody Allen's ability to raise the inner corners of his eyebrows." A Natural History of Seeing delves into both the evolution of sight and the evolution of our understanding of sight. It gives us the natural science - the physics of light and the biology of animals and humans alike - while also addressing Leonardo da Vinci's theories of perception in painting and Homer's confused and strangely limited sense of color. Panoramic in every sense, it reaches back to the first seers (and to ancient beliefs that vision is the product of mysterious optic rays) and forward to the promise of modern experiments in making robots that see.

    The sixteenth and seventeenth centuries witnessed the Copernican Revolution, which bodychecked the Earth as the pivot point of creation and joined us with the rest of the cosmos as one planet among many orbiting the Sun. Three centuries later came the second great scientific revolution: the Darwinian Revolution. It removed us from a distinct, divine biological status to place us wholly in the ebb and flow of all terrestrial life. This book describes how we’re in the midst of a third great scientific revolution, five centuries in the making: the Stardust Revolution. It is the merging of the once-disparate realms of astronomy and evolutionary biology, and of the Copernican and Darwinian Revolutions, placing life in a cosmic context. This book takes readers on a grand journey that begins on the summit of California’s Mount Wilson, where astronomers first realized that the universe is both expanding and evolving, to a radio telescope used to identify how organic molecules—the building blocks of life—are made by stars. It’s an epic story told through a scientific cast that includes some of the twentieth century’s greatest minds—including Nobel laureate Charles Townes, who discovered cosmic water—as well as the most ambitious scientific explorers of the twenty-first century, those racing to find another living planet. Today, an entirely new breed of scientists—astrobiologists and astrochemists—are taking the study of life into the space age. Astrobiologists study the origins, evolution, and distribution of life, not just on Earth, but in the universe. Stardust science is filling in the missing links in our evolutionary story, ones that extend our family tree back to the stars.

    Every day, we break our fast. Hunger explores the range of this primal experience. Sharman Apt Russell, the highly acclaimed author of Anatomy of a Rose and An Obsession with Butterflies, here takes us on a tour of hunger, from eighteen hours without food to thirty-six hours to seven days and beyond. What Russell finds-both in our bodies and in cultures around the world-is extraordinary. It is a biological process that transcends nature to shape the very of fabric of societies. In a fascinating survey of centuries of thought on hunger's unique power, she discovers an ability to adapt to it that is nothing short of miraculous. From the fasting saints of the early Christian church to activists like Mahatma Gandhi, generations have used hunger to make spiritual and political statements. Russell highlights these remarkable cases where hunger can inspire and even heal, but she also addresses the devastating impact of starvation on cultures around the world today. Written with consummate skill, a compassionate heart, and stocked with facts, figures, and fascinating lore, Hunger is an inspiring window on history and the human spirit.

    New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four dimensions in evolution -- four inheritance systems that play a role in evolution: genetic, epigenetic (or non-DNA cellular transmission of traits), behavioral, and symbolic (transmission through language and other forms of symbolic communication). These systems, they argue, can all provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution. After discussing each of the four inheritance systems in detail, Jablonka and Lamb put Humpty Dumpty together again by showing how all of these systems interact. They consider how each may have originated and guided evolutionary history and they discuss the social and philosophical implications of the four-dimensional view of evolution. Each chapter ends with a dialogue in which the authors engage the contrarieties of the fictional (and skeptical) I.M., or Ifcha Mistabra -- Aramaic for the opposite conjecture -- refining their arguments against I.M.'s vigorous counterarguments. The lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points.

    His simple but staggering theory of quantum evolution shows how quantum mechanics gives living organisms the ability to initiate specific actions, including new mutations. As Paul Davies exclaims, "if these ideas are right, they will transform our understanding of the relationship between physics and biology" and may radically revise the notion of random evolution and the debate over consciousness and free will.

    Right? Wrong, says Alex Rosenberg in How History Gets Things Wrong. Feeling especially well-informed after reading a book of popular history on the best-seller list? Don't. Narrative history is always, always wrong. It's not just incomplete or inaccurate but deeply wrong, as wrong as Ptolemaic astronomy. We no longer believe that the earth is the center of the universe. Why do we still believe in historical narrative? Our attachment to history as a vehicle for understanding has a long Darwinian pedigree and a genetic basis. Our love of stories is hard-wired. Neuroscience reveals that human evolution shaped a tool useful for survival into a defective theory of human nature.Stories historians tell, Rosenberg continues, are not only wrong but harmful. Israel and Palestine, for example, have dueling narratives of dispossession that prevent one side from compromising with the other. Henry Kissinger applied lessons drawn from the Congress of Vienna to American foreign policy with disastrous results. Human evolution improved primate mind reading—the ability to anticipate the behavior of others, whether predators, prey, or cooperators—to get us to the top of the African food chain. Now, however, this hard-wired capacity makes us think we can understand history—what the Kaiser was thinking in 1914, why Hitler declared war on the United States—by uncovering the narratives of what happened and why. In fact, Rosenberg argues, we will only understand history if we don't make it into a story.

    It offers a battery of methods that can be used to help us understand human behavior. Nevertheless, the legitimacy of this exercise is at the center of a heated controversy that has raged for over a century. Many evolutionary biologists, anthropologists and psychologists have taken these evolutionary principles and tried using them to explain a wide range of human characteristics, such as homicide, religion and sex differences in behavior. Others, however, are sceptical of these interpretations. Moreover, researchers disagree as to the best ways to use evolution to explore humanity, and a number of schools have emerged. Sense and Nonsense provides an introduction to the ideas, methods, and findings of five such schools, namely, sociobiology, human behavioural ecology, evolutionary psychology, memetics, and gene-culture co-evolution. Carefully guiding the reader through the mire of confusing terminology, claim and counter-claim, and polemical statements, Laland and Brown provide a balanced, rigorous analysis that scrutinizes both the evolutionary arguments and the allegations of the critics. This is a book that will be make fascinating reading for popular science readers, undergraduate and postgraduate students (for example, in psychology, anthropology and zoology), and to experts on one approach who would like to know more about the other perspectives. Having completed this book the reader will feel better placed to assess the legitimacy of claims made about human behavior under the name of evolution, and to make judgements as to what is sense and what is nonsense.
