EL FENÓMENO LITERARIO DE LOS ÚLTIMOS AÑOS Vuelve el tándem más exitoso para abordar el mayor misterio de la naturaleza humana: nuestro cerebro «El cerebro vive en un cuarto oscuro». «Tal es el gran misterio al que nos enfrentamos», afirma Arsuaga en este libro en el que el sapiens y el neandertal afrontan el mayor desafío de su proyecto en común, el más complejo, el que supone abrir una puerta a lo ignorado. Vivimos con la paradoja de que, pese a los avances de la neurociencia en los últimos años, el cerebro, que rige nuestra conexión con el mundo, continúa siendo el gran desconocido. La identidad, la inteligencia la natural y la artificial y la memoria, así como las condiciones para que saltara la chispa y surgiera la conciencia que nos distingue a los humanos del resto de las especies constituyen las tramas de este libro, todas ellas atravesadas por la sabiduría y el humor, y por el eje narrativo de la singular relación entre el científico y el novelista. La crítica ha dicho: «La fiesta de la inteligencia». David Broncano «Un libro para su cerebro y para su formación humana, cívica y científica, sobre todo. […] Un viaje con dos hombres sabios que tratarán de explicarte, de esbozarte el sueño de un claro laberinto que labra un arduo cristal: el infinito, que es el cerebro». Bernardo Munuera Montero, Zenda «Millás y Arsuaga parecen haber encontrado una fórmula perfecta que combina ingenio, entretenimiento y pulgación. Un diálogo pertidísimo». Marta Domínguez, Página dos (RTVE) «Un sabio, divertido y puntilloso combate de boxeo entre un Homo sapiens y un neandertal [que] casan ciencia, literatura y humor. [...] Un apasionante viaje por las profundidades de la materia gris». Miguel Lorenci, Ideal de Granada «Yo prefiero a los clásicos, y Arsuaga y Millás lo son. Dos señores sabios, curiosos, entretenidos y tan distintos que se han hecho como Quijote y Sancho. Y así van cabalgando juntos. [...] Yo estoy disfrutando de volver a tenerlos en mis manos». Sandra Faginas, La Voz de Galicia «Un portento de originalidad que mezcla ciencia, pulgación e imaginación con toneladas de ironía para entender de dónde venimos, quiénes somos y adónde vamos». Miguel Lorenci, La Verdad «Una extraña pareja, una suerte de Walter Matthau y Jack Lemmon a la española. Dos mentes inquietas que se han unido para escribir [...], cuestionar y traer al lenguaje del común de los mortales planteamientos y reflexiones». Pilar Martín, EFE «Un fascinante viaje por la existencia humana, donde el humor pilota la nave». César Suárez, Telva «Se une la erudición brutal de Arsuaga a la capacidad interpretativa y narrativa de Millás». Andreu Buenafuente «Un libro especial. Distinto. Hasta los autores reconocen haber alumbrado un nuevo género». El Cultural «Una maravilla. Un libro lleno de humor y de bondad. Sí, bondad. Un libro que busca entender el misterio de la vida». Manuel Vilas

In our modern world, it is easy to overlook the natural world all around us. Only major life events, such as birth, injury, disease, and death, remind us that we are still biological organisms. We'interact'with nature in controlled and safe environments, such as zoos, theme parks, or through different forms of media. Television shows, films, and books are nearly always in exotic locations (e.g., the Kalahari Desert, the deep ocean, or Antarctica), but they inadvertently reinforce our separation from nature. Biology happens somewhere else. Author Gary Howard seeks to change that perception. The Biology of Us describes the common but fascinating examples of biology and nature that are hidden in plain sight in our daily lives. It focuses on human biology, but describes animals and plants all around, on, and in us to put human features into an evolutionary context. Many aspects of ourselves and our normal activities are examples of evolution: breathing, eating, standing up, communicating, telling time, and more. This book illustrates evolutionary strategies used successfully by common organisms for hundreds of millions of years. Howard shows that the organisms in our daily lives are not trivial neighbors or even pests but are just as amazing as those in the Serengeti or the Galápagos Islands.

A dazzling follow-up to Life As Told by a Sapiens to a Neanderthal. ‘We would love to discover that each species has a biological clock in its cells, because, if that clock existed and if we were able to find it, perhaps we could stop it and thus become eternal,'Arsuaga tells Millás in this book, in which science is intertwined with literature. The paleontologist reveals essential aspects of our existence to the writer, and debates the advisability of transmitting his random vision of life to a dieting Millás, who discovers that old age is a country in which he still feels like a foreigner. After the extraordinary international reception of Life As Told by a Sapiens to a Neanderthal, the most brilliant double act in Spanish literature once again dazzle the reader by addressing topics such as death and eternity, longevity, disease, ageing, natural selection, programmed death, and survival. Here you will find humour, biology, nature, life, a lot of life … and two fascinating characters, the Sapiens and the Neanderthal, who surprise us on every page with their sharp reflections on how evolution has treated us as a species. And also as individuals.

A panoramic view of the evolution of life on our planet, from its origins to humanity's future.In A History of Bodies, Brains, and Minds, Francisco Aboitiz provides a brief history of life, the brain, and cognition, from the earliest living beings to our own species. The author proceeds from the basic premise that, since evolution by natural selection is the process underlying the origin of life and its evolution on earth, the brain—and thus our minds—must also be the result of biological evolution. The aim of this book is to narrate how animal bodies came to be built with their nervous systems and how our species evolved with culture, technology, language, and consciousness.The book is organized in four parts, each delving into a different aspect of evolutionary development:• Definitions lays the groundwork by discussing the principles of biological evolution and explores the definition and mechanisms of life itself.• Beginnings describes the origins of life, starting from the emergence of the first cells to the development of neurons as the building blocks for brain networks.• The Rise of Bodies and Brains examines the evolution of animals with bilateral symmetry, the emergence of chordates and vertebrates, and the expansion and diversification of the vertebrate brain.• A Singular Ape explores Homo sapiens and our species'unique traits, such as bipedality, tool use, culture, language, communication, and consciousness.Comprehensive and deeply insightful, this book helps us understand our place in the natural world and the cosmos—as well as what the future might hold for life on earth.

A major new theory of why human intelligence has not evolved in other speciesThe Human Evolutionary Transition offers a unified view of the evolution of intelligence, presenting a bold and provocative new account of how animals and humans have followed two powerful yet very different evolutionary paths to intelligence. This incisive book shows how animals rely on robust associative mechanisms that are guided by genetic information, which enable animals to sidestep complex problems in learning and decision making but ultimately limit what they can learn. Humans embody an evolutionary transition to a different kind of intelligence, one that relies on behavioral and mental flexibility. The book argues that flexibility is useless to most animals because they lack sufficient opportunities to learn new behavioral and mental skills. Humans find these opportunities in lengthy childhoods and through culture.Blending the latest findings in fields ranging from psychology to evolutionary anthropology, The Human Evolutionary Transition draws on computational analyses of the problems organisms face, extensive overviews of empirical data on animal and human learning, and mathematical modeling and computer simulations of hypotheses about intelligence. This compelling book demonstrates that animal and human intelligence evolved from similar selection pressures while identifying bottlenecks in evolution that may explain why human-like intelligence is so rare.

How did humanity evolve? And what does our evolutionary history tell us about what it means to be human? These questions are fundamental to our identity as individuals and as a species and to our relationship with the world. But there are almost as many answers to them as there are scientists who study these topics.This book brings together more than one hundred top experts, who share their insights on the study of human evolution and what it means for understanding our past, present, and future. Sergio Almécija asks leading figures across paleontology, primatology, archaeology, genetics, and many other disciplines about their lives, their work, and the philosophical significance of human evolution. They reflect on questions that are both fun and profound: What set you down your career path? Are humans special? Where and when would you travel in a time machine? Does human evolution offer lessons for society? Is evolution compatible with spirituality and religion?Humans features a remarkably accomplished cast of contributors, including Kay Behrensmeyer, Frans de Waal, Nina Jablonski, Richard Leakey, Robert Sapolsky, and Richard Wrangham. Together, they provide a refreshing, personable, engaging, cross-disciplinary, and thought-provoking exploration of different—even diametrically opposed—ideas about our nature and evolution, what makes humans unique, and what our future might hold. This book also offers practical suggestions for readers seeking to embark on a scientific career.

The epic story of human evolution, from our primate beginnings more than five million years ago to the agricultural eraOver the course of five million years, our primate ancestors evolved from a modest population of sub-Saharan apes into the globally dominant species Homo sapiens. Along the way, humans became incredibly diverse in appearance, language, and culture. How did all of this happen? In The Five-Million-Year Odyssey, Peter Bellwood synthesizes research from archaeology, biology, anthropology, and linguistics to immerse us in the saga of human evolution, from the earliest traces of our hominin forebears in Africa, through waves of human expansion across the continents, and to the rise of agriculture and explosive demographic growth around the world.Bellwood presents our modern diversity as a product of both evolution, which led to the emergence of the genus Homo approximately 2.5 million years ago, and migration, which carried humans into new environments. He introduces us to the ancient hominins—including the australopithecines, Homo erectus, the Neanderthals, and others—before turning to the appearance of Homo sapiens circa 300,000 years ago and subsequent human movement into Eurasia, Australia, and the Americas. Bellwood then explores the invention of agriculture, which enabled farmers to disperse to new territories over the last 10,000 years, facilitating the spread of language families and cultural practices. The outcome is now apparent in our vast array of contemporary ethnicities, linguistic systems, and customs.The fascinating origin story of our varied human existence, The Five-Million-Year Odyssey underscores the importance of recognizing our shared genetic heritage to appreciate what makes us so diverse.

A Fascinating Exploration on Why the Darwinists'Theory No Longer Explains EverythingThere was once a set of ideas called the theory of evolution, conceived by clever people and confirmed by countless scientists. Then people discovered the electron microscope. This made it possible to make the molecules within the cell visible, and suddenly questions about evolution arose that were not possible before. Which force actually bundles the atoms in the right order? What moves the molecular chains into the correct position? How did the first living unit within the cell actually come about? How does inheritance work, how does information pass on to the next generation? Did humans descend only and exclusively from primates—as Charles Darwin and countless other great minds assumed—or did additional “engines” intervene in evolution? Today it is clear: countless questions can no longer be answered with the previous theory of evolution. There is a form of life called “Blob” (Physarum polycephalum). The “thing” has neither eyes nor ears, neither a mouth nor a nose or even a brain. Nevertheless, it takes in food, overcomes obstacles by the shortest route and exchanges information with other “blobs.” The “blob” contradicts any evolutionary thought that one develops from the other. Or the “gastric-brooding frogs” (Rheobatrachus) found in Australia. They hatch their young in the stomach. Impossible in a slow, evolutionary process. Everywhere there are characteristics of animals that do not want to fit into the theory of evolution anywhere. And man? Are we really the most adapted life-form on this planet? Today, more and more scientists who contradict the previous theory of evolution speak out. The theory fits the changes within the species, but it can no longer be reconciled with the inner workings of the cell. Some other influence that has so far escaped us is affecting evolution. It is called “Intelligent Design.” Intelligent planning is suspected behind this. Anyone or anything—a spirit of the universe? Aliens?—could be behind this planning. Erich von Däniken uses countless examples to demonstrate the impossibility of the previous evolutionary idea. He quotes scientists who argue against the previous teaching, but also those who defend it. Unfortunately, established science still refuses to look at discrepancies and holes in the theory of evolution, even though it is quite obvious that there is more going on with regard to the development of all species, as well as human culture, than could be explained by the theory of evolution alone.

‘Brilliant, eye-opening, and absolutely inspiring – and a riveting read.'Cass Sunstein, author of How Change Happens and co-author of Nudge What is the secret to humanity's evolutionary success? Could it be our strength, our intellect… or something much nicer? From the authors of New York Times bestseller The Genius of Dogs comes a powerful new idea about how ‘friendliness'is the key factor in the flourishing of our species. Hare and Woods present an elegant new theory called self-domestication, looking at examples of co-operation and empathy and what this can tell us about the evolutionary success of Homo sapiens…

'Riveting.... Pattison's uncanny ability [is] to write evocatively about science.... In this, he is every bit as good as the best scientist writers.'—New York Times Book Review (Editors'Choice)'Brilliant.... A work of staggering depth.'—Minneapolis Star TribuneA decade in the making, Fossil Men is a scientific detective story played out in anatomy and the natural history of the human body: the first full-length account of the discovery of a startlingly unpredicted human ancestor more than a million years older than LucyIt is the ultimate mystery: where do we come from? In 1994, a team led by fossil-hunting legend Tim White uncovered a set of ancient bones in Ethiopia's Afar region. Radiometric dating of nearby rocks indicated the resulting skeleton, classified as Ardipithecus ramidus—nicknamed “Ardi”—was an astounding 4.4 million years old, more than a million years older than the world-famous “Lucy.” The team spent the next 15 years studying the bones in strict secrecy, all while continuing to rack up landmark fossil discoveries in the field and becoming increasingly ensnared in bitter disputes with scientific peers and Ethiopian bureaucrats. When finally revealed to the public, Ardi stunned scientists around the world and challenged a half-century of orthodoxy 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. But the discovery of Ardi wasn't just a leap forward in understanding the roots of humanity--it was an attack on scientific convention and the leading authorities of human origins, triggering an epic feud about the oldest family skeleton.In Fossil Men, acclaimed journalist Kermit Pattison brings us a cast of eccentric, obsessive scientists, including White, an uncompromising perfectionist whose virtuoso skills in the field were matched only by his propensity for making enemies; Gen Suwa, a Japanese savant whose deep expertise about teeth rivaled anyone on Earth; Owen Lovejoy, a onetime creationist-turned-paleoanthropologist with radical insights into human locomotion; Berhane Asfaw, who survived imprisonment and torture to become Ethiopia's most senior paleoanthropologist; Don Johanson, the discoverer of Lucy, who had a rancorous falling out with the Ardi team; and the Leakeys, for decades the most famous family in paleoanthropology. Based on a half-decade of research in Africa, Europe and North America, Fossil Men is not only a brilliant investigation into the origins of the human lineage, but the oldest of human emotions: curiosity, jealousy, perseverance and wonder.

“A fascinating new analysis of human violence, filled with fresh ideas and gripping evidence from our primate cousins, historical forebears, and contemporary neighbors.”—Steven Pinker, author of The Better Angels of Our NatureWe Homo sapiens can be the nicest of species and also the nastiest. What occurred during human evolution to account for this paradox? What are the two kinds of aggression that primates are prone to, and why did each evolve separately? How does the intensity of violence among humans compare with the aggressive behavior of other primates? How did humans domesticate themselves? And how were the acquisition of language and the practice of capital punishment determining factors in the rise of culture and civilization?Authoritative, provocative, and engaging, The Goodness Paradox offers a startlingly original theory of how, in the last 250 million years, humankind became an increasingly peaceful species in daily interactions even as its capacity for coolly planned and devastating violence remains undiminished. In tracing the evolutionary histories of reactive and proactive aggression, biological anthropologist Richard Wrangham forcefully and persuasively argues for the necessity of social tolerance and the control of savage divisiveness still haunting us today.

All humans share three origins: the beginning of our individual lives, the appearance of life on Earth, and the formation of our planetary home. Life through Time and Space brings together the latest discoveries in both biology and astronomy to examine our deepest questions about where we came from, where we are going, and whether we are alone in the cosmos.A distinctive voice in the growing field of astrobiology, Wallace Arthur combines embryological, evolutionary, and cosmological perspectives to tell the story of life on Earth and its potential to exist elsewhere in the universe. He guides us on a journey through the myriad events that started with the big bang and led to the universe we inhabit today. Along the way, readers learn about the evolution of life from a primordial soup of organic molecules to complex plants and animals, about Earth's geological transformation from barren rock to diverse ecosystems, and about human development from embryo to infant to adult. Arthur looks closely at the history of mass extinctions and the prospects for humanity's future on our precious planet.Do intelligent aliens exist on a distant planet in the Milky Way, sharing the three origins that characterize all life on Earth? In addressing this question, Life through Time and Space tackles the many riddles of our place and fate in the universe that have intrigued human beings since they first gazed in wonder at the nighttime sky.

How our ability to learn from each other has been the essential ingredient to our remarkable success as a speciesHuman beings are a very different kind of animal. We have evolved to become the most dominant species on Earth. We have a larger geographical range and process more energy than any other creature alive. This astonishing transformation is usually explained in terms of cognitive ability—people are just smarter than all the rest. But in this compelling book, Robert Boyd argues that culture—our ability to learn from each other—has been the essential ingredient of our remarkable success.A Different Kind of Animal demonstrates that while people are smart, we are not nearly smart enough to have solved the vast array of problems that confronted our species as it spread across the globe. Over the past two million years, culture has evolved to enable human populations to accumulate superb local adaptations that no individual could ever have invented on their own. It has also made possible the evolution of social norms that allow humans to make common cause with large groups of unrelated individuals, a kind of society not seen anywhere else in nature. This unique combination of cultural adaptation and large-scale cooperation has transformed our species and assured our survival—making us the different kind of animal we are today.Based on the Tanner Lectures delivered at Princeton University, A Different Kind of Animal features challenging responses by biologist H. Allen Orr, philosopher Kim Sterelny, economist Paul Seabright, and evolutionary anthropologist Ruth Mace, as well as an introduction by Stephen Macedo.

The twenty-first century presents an increasing number of environmental problems, including toxic pollution, global warming, destruction of tropical forests, extinction of biological diversity, and depletion of natural resources. These environmental problems are generally due to human behavior, namely over-consumption of resources and overpopulation. Designing effective policies to address these problems requires a deep understanding of human behavior as well as ecology. This in turn requires considerations of human nature, and the evolutionary'design'of the human mind.Evolutionary research on human behavior has profound implications for the environmental sciences. The aim of this collection is to bring together a variety of chapters that show how and why. Part 1,'Human Nature and Resource Conservation,'addresses environmental problems from different evolutionary perspectives. Part 2,'The Ecological Noble Savage Hypothesis,'examines the notion that our environmental problems are due to Western culture, and that our ancestors and people in indigenous societies lived in harmony with nature until the corrupting influences of Western culture. Part 3,'The Tragedy of the Commons,'explores the conservation of common-pool or open-access natural resources, such as fisheries, forests, grazing lands, freshwater, and clean air. Part 4,'The Evolution of Discounting and Conspicuous Consumption,'looks at the problem of explaining why people are so ecologically short-sighted and why people in developed countries consume so many resources. Part 5,'Overpopulation and Fertility Declines,'addresses the evolution of human reproductive decisions. Part 6,'Biophilia,'aims to explain why people cherish nature as well as destroy it.The goal of this volume is to introduce environmental thinkers to evolutionary perspectives on human behavior, and the new interdisciplinary sciences of evolutionary psychology and behavioral ecology. This reader aims to help bridge

Humans possess an extraordinary capacity for culture, from the arts and language to science and technology. But how did the human mind—and the uniquely human ability to devise and transmit culture—evolve from its roots in animal behavior? Darwin's Unfinished Symphony presents a captivating new theory of human cognitive evolution. This compelling and accessible book reveals how culture is not just the magnificent end product of an evolutionary process that produced a species unlike all others—it is also the key driving force behind that process. Kevin N. Lala tells the story of the painstaking fieldwork, the key experiments, the false leads, and the stunning scientific breakthroughs that led to this new understanding of how culture transformed human evolution. It is the story of how Darwin's intellectual descendants picked up where he left off and took up the challenge of providing a scientific account of the evolution of the human mind.

What teeth can teach us about the evolution of the human speciesWhether we realize it or not, we carry in our mouths the legacy of our evolution. Our teeth are like living fossils that can be studied and compared to those of our ancestors to teach us how we became human. In Evolution's Bite, noted paleoanthropologist Peter Ungar brings together for the first time cutting-edge advances in understanding human evolution and climate change with new approaches to uncovering dietary clues from fossil teeth to present a remarkable investigation into the ways that teeth—their shape, chemistry, and wear—reveal how we came to be.Ungar describes how a tooth's'foodprints'—distinctive patterns of microscopic wear and tear—provide telltale details about what an animal actually ate in the past. These clues, combined with groundbreaking research in paleoclimatology, demonstrate how a changing climate altered the food options available to our ancestors, what Ungar calls the biospheric buffet. When diets change, species change, and Ungar traces how diet and an unpredictable climate determined who among our ancestors was winnowed out and who survived, as well as why we transitioned from the role of forager to farmer. By sifting through the evidence—and the scars on our teeth—Ungar makes the important case for what might or might not be the most natural diet for humans.Traveling the four corners of the globe and combining scientific breakthroughs with vivid narrative, Evolution's Bite presents a unique dental perspective on our astonishing human development.

The astonishing new story of human originsWas Darwin wrong when he traced our origins to Africa? The Real Planet of the Apes makes the explosive claim that it was in Europe, not Africa, where apes evolved the most important hallmarks of our human lineage—such as dexterous hands and larger brains. In this compelling and accessible book, David Begun, one of the world's leading paleoanthropologists, transports readers to an epoch in the remote past when the Earth was home to many migratory populations of ape species.Drawing on the latest astonishing discoveries in the fossil record as well as his own experiences conducting field expeditions across Europe and Asia, Begun provides a sweeping evolutionary history of great apes and humans. He tells the story of how one of the earliest members of our evolutionary group—a new kind of primate called Proconsul—evolved from lemur-like monkeys in the primeval forests of Africa. Begun vividly describes how, over the next 10 million years, these hominoids expanded into Europe and Asia and evolved climbing and hanging adaptations, longer maturation times, and larger brains, setting the stage for the emergence of humans. As the climate deteriorated in Europe around 10 million years ago, these apes either died out or migrated south, reinvading the African continent and giving rise to the lineages of the gorilla, chimpanzee, and, ultimately, the human.Presenting startling new insights about our fossil ape ancestors, The Real Planet of the Apes is a book that fundamentally alters our understanding of human origins.

Are humans still subject to the forces of evolution? An evolutionary biologist provides surprising insights into the future of Homo sapiens In this intriguing book, evolutionary biologist Scott Solomon draws on the explosion of discoveries in recent years to examine the future evolution of our species. Combining knowledge of our past with current trends, Solomon offers convincing evidence that evolutionary forces still affect us today. But how will modernization—including longer lifespans, changing diets, global travel, and widespread use of medicine and contraceptives—affect our evolutionary future? Solomon presents an entertaining and accessible review of the latest research on human evolution in modern times, drawing on fields from genomics to medicine and the study of our microbiome. Surprising insights, on topics ranging from the rise of online dating and Cesarean sections to the spread of diseases such as HIV and Ebola, suggest that we are entering a new phase in human evolutionary history—one that makes the future less predictable and more interesting than ever before.

An authoritative exploration of why understanding evolution is crucial to human life todayIt is easy to think of evolution as something that happened long ago, or that occurs only in'nature,'or that is so slow that its ongoing impact is virtually nonexistent when viewed from the perspective of a single human lifetime. But we now know that when natural selection is strong, evolutionary change can be very rapid. In this book, some of the world's leading scientists explore the implications of this reality for human life and society. With some twenty-three essays, this volume provides authoritative yet accessible explorations of why understanding evolution is crucial to human life—from dealing with climate change and ensuring our food supply, health, and economic survival to developing a richer and more accurate comprehension of society, culture, and even what it means to be human itself. Combining new essays with essays revised and updated from the acclaimed Princeton Guide to Evolution, this collection addresses the role of evolution in aging, cognition, cooperation, religion, the media, engineering, computer science, and many other areas. The result is a compelling and important book about how evolution matters to humans today.The contributors are Dan I. Andersson, Francisco J. Ayala, Amy Cavanaugh, Cameron R. Currie, Dieter Ebert, Andrew D. Ellington, Elizabeth Hannon, John Hawks, Paul Keim, Richard E. Lenski, Tim Lewens, Jonathan B. Losos, Virpi Lummaa, Jacob A. Moorad, Craig Moritz, Martha M. Muñoz, Mark Pagel, Talima Pearson, Robert T. Pennock, Daniel E. L. Promislow, Erik M. Quandt, David C. Queller, Robert C. Richardson, Eugenie C. Scott, H. Bradley Shaffer, Joan E. Strassmann, Alan R.

The dean of Columbia University's medical school explains why our bodies are out of sync with today's environment and how we can correct this to save our health. Over the past 200 years, human life-expectancy has approximately doubled. Yet we face soaring worldwide rates of obesity, diabetes, high blood pressure, mental illness, heart disease, and stroke. In his fascinating new book, Dr. Lee Goldman presents a radical explanation: The key protective traits that once ensured our species'survival are now the leading global causes of illness and death. Our capacity to store food, for example, lures us into overeating, and a clotting system designed to protect us from bleeding to death now directly contributes to heart attacks and strokes. A deeply compelling narrative that puts a new spin on evolutionary biology, Too Much of a Good Thing also provides a roadmap for getting back in sync with the modern world.

Why are men, like other primate males, usually the aggressors and risk takers? Why do women typically have fewer sexual partners? In Why Sex Matters, Bobbi Low ranges from ancient Rome to modern America, from the Amazon to the Arctic, and from single-celled organisms to international politics, to show that these and many other questions about human behavior largely come down to evolution and sex. More precisely, as she shows in this uniquely comprehensive and accessible survey of behavioral and evolutionary ecology, they come down to the basic principle that all organisms evolved to maximize their reproductive success and seek resources to do so, but that sometimes cooperation and collaboration are the most effective ways to succeed.This newly revised edition has been thoroughly updated to include the latest research and reflect exciting changes in the field, including how our evolutionary past continues to affect our ecological present.

How our collective intelligence has helped us to evolve and prosperHumans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals? This book shows that the secret of our success lies not in our innate intelligence, but in our collective brains—on the ability of human groups to socially interconnect and learn from one another over generations.Drawing insights from lost European explorers, clever chimpanzees, mobile hunter-gatherers, neuroscientific findings, 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 cultural 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. Later on, some collective brains generated and recombined powerful concepts, such as the lever, wheel, screw, and writing, while also creating the institutions that continue to alter our motivations and perceptions. Henrich shows how our genetics and biology are inextricably interwoven with cultural evolution, and how culture-gene interactions launched our species on an extraordinary evolutionary trajectory.Tracking clues from our ancient past to the present, The Secret of Our Success explores how the evolution of both our cultural and social natures produce a collective intelligence that explains both our species'immense success and the origins of human uniqueness.

“Extraordinary.... takes the reader into the overlap of medicine, ecology, and evolutionary biology to reveal an important domain of the human condition.” —Edward O. Wilson, Pulitzer Prize–winning author of Anthill and The Future of Life We evolved in a wilderness of parasites, mutualists, and pathogens, but we no longer see ourselves as being part of nature. In the name of progress and clean living, we scrub much of nature off our bodies and try to remove whole kinds of life—parasites, bacteria, mutualists, and predators—to allow ourselves to live free of wild danger. Nature, in this new world, is the landscape outside, a kind of living painting that is pleasant to contemplate but nice to have escaped. The truth, though, according to biologist Rob Dunn, is that while “clean living” has benefited us in some ways, it has also made us sicker in others. As Dunn reveals, our modern disconnect from the web of life has resulted in unprecedented effects that immunologists, evolutionary biologists, psychologists, and other scientists are only beginning to understand. Diabetes, autism, allergies, many anxiety disorders, autoimmune diseases, and even tooth, jaw, and vision problems are increasingly plaguing bodies that have been removed from the ecological context in which they existed for millennia. In this eye-opening book, Dunn considers the crossroads at which we find ourselves. Through the stories of visionaries, Dunn argues that we can create a richer nature, one in which we choose to surround ourselves with species that benefit us, not just those that, despite us, survive. “A pleasure to read.” —Boston Globe “[Dunn's] sure use of language, scientific research, and humor... keep the reader highly engaged.” —New York Journal of Books “Not merely interesting but gripping.” —Booklist, starred review

Human Evolutionary Genetics is a groundbreaking text which for the first time brings together molecular genetics and genomics to the study of the origins and movements of human populations. Starting with an overview of molecular genomics for the non-specialist (which can be a useful review for those with a more genetic background), the book shows h

Evolution and the Emergent Self is an eloquent and evocative new synthesis that explores how the human species emerged from the cosmic dust. Lucidly presenting ideas about the rise of complexity in our genetic, neuronal, ecological, and ultimately cosmological settings, the author takes readers on a provocative tour of modern science's quest to understand our place in nature and in our universe. Readers fascinated with'Big History'and drawn to examine big ideas will be challenged and enthralled by Raymond L. Neubauer's ambitious narrative.How did humans emerge from the cosmos and the pre-biotic Earth, and what mechanisms of biological, chemical, and physical sciences drove this increasingly complex process? Neubauer presents a view of nature that describes the rising complexity of life in terms of increasing information content, first in genes and then in brains. The evolution of the nervous system expanded the capacity of organisms to store information, making learning possible. In key chapters, the author portrays four species with high brain:body ratios—chimpanzees, elephants, ravens, and dolphins—showing how each species shares with humans the capacity for complex communication, elaborate social relationships, flexible behavior, tool use, and powers of abstraction. A large brain can have a hierarchical arrangement of circuits that facilitates higher levels of abstraction.Neubauer describes this constellation of qualities as an emergent self, arguing that self-awareness is nascent in several species besides humans and that potential human characteristics are embedded in the evolutionary process and have emerged repeatedly in a variety of lineages on our planet. He ultimately demonstrates that human culture is not a unique offshoot of a language-specialized primate, but an analogue of fundamental mechanisms that organisms have used since the beginning of life on Earth to gather and process information in order to buffer themselves from fluctuations in the environment.Neubauer also views these developments in a cosmic setting, detailing open thermodynamic systems that grow more complex as the energy flowing through them increases. Similar processes of increasing complexity can be found in the'self-organizing'structures of both living and nonliving forms. Recent evidence from astronomy indicates that planet formation may be nearly as frequent as star formation. Since life makes use of the elements commonly seeded into space by burning and expiring stars, it is reasonable to speculate that the evolution of life and intelligence that happened on our planet may be found across the universe.

As news of war and terror dominates the headlines, scientist Malcolm Potts and veteran journalist Thomas Hayden take a step back to explain it all. In the spirit of Guns, Germs and Steel, Sex and War asks the basic questions: Why is war so fundamental to our species? And what can we do about it?Malcolm Potts explores these questions from the frontlines, as a witness to war-torn countries around the world. As a scientist and obstetrician, Potts has worked with governments and aid organizations globally, and in the trenches with women who have been raped and brutalized in the course of war. Combining their own experience with scientific findings in primatology, genetics, and anthropology, Potts and Hayden explain war's pivotal position in the human experience and how men in particular evolved under conditions that favored gang behavior, rape, and organized aggression. Drawing on these new insights, they propose a rational plan for making warfare less frequent and less brutal in the future.Anyone interested in understanding human nature, warfare, and terrorism at their most fundamental levels will find Sex and War to be an illuminating work, and one that might change the way they see the world.

In the early 1890s the theory of evolution gained an unexpected ally: the Edison phonograph. An amateur scientist used the new machine—one of the technological wonders of the age—to record monkey calls, play them back to the monkeys, and watch their reactions. From these soon-famous experiments he judged that he had discovered “the simian tongue,” made up of words he was beginning to translate, and containing the rudiments from which human language evolved. Yet for most of the next century, the simian tongue and the means for its study existed at the scientific periphery. Both returned to great acclaim only in the early 1980s, after a team of ethologists announced that experimental playback showed certain African monkeys to have rudimentarily meaningful calls. Drawing on newly discovered archival sources and interviews with key scientists, Gregory Radick here reconstructs the remarkable trajectory of a technique invented and reinvented to listen in on primate communication. Richly documented and powerfully argued, The Simian Tongue charts the scientific controversies over the evolution of language from Darwin's day to our own, resurrecting the forgotten debts of psychology, anthropology, and other behavioral sciences to the Victorian debate about the animal roots of human language.

Resistance to malaria. Blue eyes. Lactose tolerance. What do all of these traits have in common? Every one of them has emerged in the last 10,000 years. Scientists have long believed that the'great leap forward'that occurred some 40,000 to 50,000 years ago in Europe marked end of significant biological evolution in humans. In this stunningly original account of our evolutionary history, top scholars Gregory Cochran and Henry Harpending reject this conventional wisdom and reveal that the human species has undergone a storm of genetic change much more recently. Human evolution in fact accelerated after civilization arose, they contend, and these ongoing changes have played a pivotal role in human history. They argue that biology explains the expansion of the Indo-Europeans, the European conquest of the Americas, and European Jews'rise to intellectual prominence. In each of these cases, the key was recent genetic change: adult milk tolerance in the early Indo-Europeans that allowed for a new way of life, increased disease resistance among the Europeans settling America, and new versions of neurological genes among European Jews. Ranging across subjects as diverse as human domestication, Neanderthal hybridization, and IQ tests, Cochran and Harpending's analysis demonstrates convincingly that human genetics have changed and can continue to change much more rapidly than scientists have previously believed. A provocative and fascinating new look at human evolution that turns conventional wisdom on its head, The 10,000 Year Explosion reveals the ongoing interplay between culture and biology in the making of the human race.

Richard Dawkins transformed our view of God in his blockbuster, The God Delusion, which sold millions of copies in English alone. He revolutionized the way we see natural selection in the seminal bestseller The Selfish Gene. Now, he launches a fierce counterattack against proponents of'Intelligent Design'in his New York Times bestseller, The Greatest Show on Earth.'Intelligent Design'is being taught in our schools; educators are being asked to'teach the controversy'behind evolutionary theory. There is no controversy. Dawkins sifts through rich layers of scientific evidence—from living examples of natural selection to clues in the fossil record; from natural clocks that mark the vast epochs wherein evolution ran its course to the intricacies of developing embryos; from plate tectonics to molecular genetics—to make the airtight case that'we find ourselves perched on one tiny twig in the midst of a blossoming and flourishing tree of life and it is no accident, but the direct consequence of evolution by non-random selection.'His unjaded passion for the natural world turns what might have been a negative argument, exposing the absurdities of the creationist position, into a positive offering to the reader: nothing less than a master's vision of life, in all its splendor.

In Germs, Genes and Civilization, Dr. David Clark tells the story of the microbe-driven epidemics that have repeatedly molded our human destinies. You'll discover how your genes have been shaped through millennia spent battling against infectious diseases. You'll learn how epidemics have transformed human history, over and over again, from ancient Egypt to Mexico, the Romans to Attila the Hun. You'll learn how the Black Death epidemic ended the Middle Ages, making possible the Renaissance, western democracy, and the scientific revolution. Clark demonstrates how epidemics have repeatedly shaped not just our health and genetics, but also our history, culture, and politics. You'll even learn how they may influence religion and ethics, including the ways they may help trigger cultural cycles of puritanism and promiscuity. Perhaps most fascinating of all, Clark reveals the latest scientific and philosophical insights into the interplay between microbes, humans, and society - and previews what just might come next.

Human beings have astonishing genetic vulnerabilities. More than half of us will die from complex diseases that trace directly to those vulnerabilities, and the modern world we've created places us at unprecedented risk from them. In It Takes a Genome, Greg Gibson posits a revolutionary new hypothesis: Our genome is out of equilibrium, both with itself and its environment. Simply put, our genes aren't coping well with modern culture. Our bodies were never designed to subsist on fat and sugary foods; our immune systems weren't designed for today's clean, bland environments; our minds weren't designed to process hard-edged, artificial electronic inputs from dawn ‘til midnight. And that's why so many of us suffer from chronic diseases that barely touched our ancestors. Gibson begins by revealing the stunningly complex ways in which multiple genes cooperate and interact to shape our bodies and influence our behaviors. Then, drawing on the very latest science, he explains the genetic “mismatches” that increasingly lead to cancer, diabetes, inflammatory and infectious diseases, AIDS, depression, and senility. He concludes with a look at the probable genetic variations in human psychology, sharing the evidence that traits like introversion and agreeableness are grounded in equally complex genetic interactions. It Takes A Genome demolishes yesterday's stale debates over “nature vs. nurture,” introducing a new view that is far more intriguing, and far closer to the truth. See how broken genes cause cancer Meet the body's “genetic repairmen”—and understand what happens when they fail The growing price of the modern lifestyle Why one-third of all Westerners have obesity, Type 2 diabetes, or other signs of “metabolic syndrome” The Alzheimer's generation Why some of us are predisposed to dementia What's really normal: the deepest lessons of the human genome The remarkable diversity of physical and emotional “normality”

In Prehistory, the award-winning archaeologist and renowned scholar Colin Renfrew covers human existence before the advent of written records–which is to say, the overwhelming majority of our time here on earth. But Renfrew also opens up to discussion, and even debate, the term “prehistory” itself, giving an incisive, concise, and lively survey of the past, and how scholars and scientists labor to bring it to light. Renfrew begins by looking at prehistory as a discipline, particularly how developments of the past century and a half–advances in archaeology and geology; Darwin's ideas of evolution; discoveries of artifacts and fossil evidence of our human ancestors; and even more enlightened museum and collection curatorship–have fueled continuous growth in our knowledge of prehistory. He details how breakthroughs such as radiocarbon dating and DNA analysis have helped us to define humankind's past–how things have changed–much more clearly than was possible just a half century ago. Answers for why things have changed, however, continue to elude us, so Renfrew discusses some of the issues and challenges past and present that confront the study of prehistory and its investigators. In the book's second part, Renfrew shifts the narrative focus, offering a summary of human prehistory from early hominids to the rise of literate civilization that is refreshingly free from conventional wisdom and grand “unified” theories. The author's own case studies encompass a vast geographical and chronological range–the Orkney Islands, the Balkans, the Indus Valley, Peru, Ireland, and China–and help to explain the formation and development of agriculture and centralized societies. He concludes with a fascinating chapter on early writing systems, “From Prehistory to History.” In this invaluable, brief account of human development prior to the last four millennia, Colin Renfrew delivers a meticulously researched and passionately argued chronicle about our life on earth, and our ongoing quest to understand it.

Experts investigate communicative flexibility (in both form and usage of signals) as the foundation of the evolution of complex communication systems, including human language.The evolutionary roots of human communication are difficult to trace, but recent comparative research suggests that the first key step in that evolutionary history may have been the establishment of basic communicative flexibility—the ability to vocalize freely combined with the capability to coordinate vocalization with communicative intent. The contributors to this volume investigate how some species (particularly ancient hominids) broke free of the constraints of “fixed signals,” actions that were evolved to communicate but lack the flexibility of language—a newborn infant's cry, for example, always signals distress and has a stereotypical form not modifiable by the crying baby. Fundamentally, the contributors ask what communicative flexibility is and what evolutionary conditions can produce it. The accounts offered in these chapters are notable for taking the question of language origins farther back in evolutionary time than in much previous work. Many contributors address the very earliest communicative break of the hominid line from the primate background; others examine the evolutionary origins of flexibility in, for example, birds and marine mammals. The volume's interdisciplinary theoretical perspectives illuminate issues that are on the cutting edge of recent research on this topic.ContributorsStéphanie Barbu, Curt Burgess, Josep Call, Laurance Doyle, Julia Fischer, Michael Goldstein, Ulrike Griebel, Kurt Hammerschmidt, Sean Hanser, Martine Hausberger, Laurence Henry, Allison Kaufman, Stan Kuczaj, Robert F.

The central concern of this book is us human beings. The authors'basic question is: ‘How is it that we can live in mutual care, have ethical concerns, and at the same time deny all that through the rational justification of aggression?'The authors answer this basic question indirectly by providing a look into the fundaments of our biological constitution, concentrating on what they term emotioning, that is the flow of emotions in daily life that guides the flow of the systemic conservation of a manner of living. Maturana and Verden-Zöller claim that the fundamental emotion that gave rise to humans as sapient languaging beings was love, and that this remains our fundament even when other emotions become socially prevalent.

This classic work on the rules of sex -- updated for a new generation -- is still as provocative as the day it was published, providing simple explanations for any and all questions about what happens in the bedroom.Sex isn't as complicated as we make it. In Sperm Wars, evolutionary biologist Robin Baker argues that every question about human sexuality can be explained by one simple thing: sperm warfare. In the interest of promoting competition between sperm to fertilize the same egg, evolution has built men to conquer and monopolize women while women are built to seek the best genetic input on offer from potential sexual partners.Baker reveals, through a series of provocative fictional scene, the far-reaching implications of sperm competition. 10% of children are not fathered by their'fathers;'over 99% of a man's sperm exists simply to fight off all other men's sperm; and a woman is far more likely to conceive through a casual fling than through sex with her regular partner.From infidelity, to homosexuality, to the female orgasm, Sperm Wars turns on every light in the bedroom. Now with new material reflecting the latest research on sperm warfare, this milestone of popular science will still surprise, entertain, and even shock.

This book describes the role of the obligate inhabitants of all vertebrate genomes—endogenous retroviruses, especially those emerged in genomes rather recently, during primate evolution. It specially focuses on human endogenous retroviruses as well as other retroelements.

This volume, published in honor of the occasion of David Pilbeam's 65th birthday, covers major topics in human, primate, and mammalian evolution, mostly from the Miocene to the present. The papers emphasize novel interpretations of several key areas of longstanding interest and importance, including Miocene biogeography and hominoid evolution, the origins of hominids, and new interpretations of the hominid fossil record.In terms of content, most of the papers tackle key issues in the evolution of hominoids and hominids in terms of systematic paleoenvironmental and behavioral questions. More broadly, however, the papers explore the epistemological problems of how one interprets the past from the available data.

Thomas H. Huxley was one of the first supporters of Charles Darwin's theory of evolution by natural selection, and he did more than any other writer to advance its acceptance among scientists and nonscientists alike. His most famous book, Man's Place in Nature, published only five years after Darwin's The Origin of Species, offers a compelling review of primate and human paleontology, and is the first attempt to apply Darwin's theory to human beings. As compelling a piece of analysis now as it was 140 years ago, Man's Place in Nature is a must for every science lover's library.

We emerged after millions of years of evolution, first in the rainforest and then in the dry savanna bush. This nomadic way of life was characterised by seasonal and geographical variation of food; scarcity, particularly of high-energy food containing fats and sugar; and walking as the main form of exercise, with sudden bursts of energy either to catch prey or to avoid becoming prey. Society was organised into structured, small-groups, contact among whom was very limited under normal conditions.After this 25 million-year period of evolution, however, we have now entered a period of de-evolution, in which we shape the world instead of it shaping us. We now have plenty of food (particularly fats, sugar and proteins), with regular'social'feedings even when we do not need food. Food in supermarkets is not subject to seasonal variations and we are fairly static physically (watching television being more frequent than exercise), without sudden use of high levels of energy. Socially, there are too many people, too much contact, causing stress and confusion. We must look to the small pockets of our former way of life which still survive in some parts of Africa to explain our real evolutionary background and nature. We cannot go back, but knowing who we are will help us to survive and to create a better world, according to our true evolutionary plan.

Reproduction is among the most basic of human biological functions, both for our distant ancestors and for ourselves, whether we live on the plains of Africa or in North American suburbs. Our reproductive biology unites us as a species, but it has also been an important engine of our evolution. In the way our bodies function today we can see both the imprint of our formative past and implications for our future. It is the infinitely subtle and endlessly dramatic story of human reproduction and its evolutionary context that Peter T. Ellison tells in On Fertile Ground.Ranging from the latest achievements of modern fertility clinics to the lives of subsistence farmers in the rain forests of Africa, this book offers both a remarkably broad and a minutely detailed exploration of human reproduction. Ellison, a leading pioneer in the field, combines the perspectives of anthropology, stressing the range and variation of human experience; ecology, sensitive to the two-way interactions between humans and their environments; and evolutionary biology, emphasizing a functional understanding of human reproductive biology and its role in our evolutionary history.Whether contrasting female athletes missing their periods and male athletes using anabolic steroids with Polish farm women and hunter-gatherers in Paraguay, or exploring the intricate choreography of an implanting embryo or of a nursing mother and her child, On Fertile Ground advances a rich and deeply satisfying explanation of the mechanisms by which we reproduce and the evolutionary forces behind their design.

A biologist and an anthropologist use evolutionary biology to explain the causes and inform the prevention of rape.In this controversial book, Randy Thornhill and Craig Palmer use evolutionary biology to explain the causes of rape and to recommend new approaches to its prevention. According to Thornhill and Palmer, evolved adaptation of some sort gives rise to rape; the main evolutionary question is whether rape is an adaptation itself or a by-product of other adaptations. Regardless of the answer, Thornhill and Palmer note, rape circumvents a central feature of women's reproductive strategy: mate choice. This is a primary reason why rape is devastating to its victims, especially young women. Thornhill and Palmer address, and claim to demolish scientifically, many myths about rape bred by social science theory over the past twenty-five years. The popular contention that rapists are not motivated by sexual desire is, they argue, scientifically inaccurate.Although they argue that rape is biological, Thornhill and Palmer do not view it as inevitable. Their recommendations for rape prevention include teaching young males not to rape, punishing rape more severely, and studying the effectiveness of'chemical castration.'They also recommend that young women consider the biological causes of rape when making decisions about dress, appearance, and social activities. Rape could cease to exist, they argue, only in a society knowledgeable about its evolutionary causes.The book includes a useful summary of evolutionary theory and a comparison of evolutionary biology's and social science's explanations of human behavior. The authors argue for the greater explanatory power and practical usefulness of evolutionary biology. The book is sure to stir up discussion both on the specific topic of rape and on the larger issues of how we understand and influence human behavior.

Are humans by nature hierarchical or egalitarian? Hierarchy in the Forest addresses this question by examining the evolutionary origins of social and political behavior. Christopher Boehm, an anthropologist whose fieldwork has focused on the political arrangements of human and nonhuman primate groups, postulates that egalitarianism is in effect a hierarchy in which the weak combine forces to dominate the strong.The political flexibility of our species is formidable: we can be quite egalitarian, we can be quite despotic. Hierarchy in the Forest traces the roots of these contradictory traits in chimpanzee, bonobo, gorilla, and early human societies. Boehm looks at the loose group structures of hunter-gatherers, then at tribal segmentation, and finally at present-day governments to see how these conflicting tendencies are reflected.Hierarchy in the Forest claims new territory for biological anthropology and evolutionary biology by extending the domain of these sciences into a crucial aspect of human political and social behavior. This book will be a key document in the study of the evolutionary basis of genuine altruism.

Nobel laureate Erwin Schrödinger's What is Life? is one of the great science classics of the twentieth century. A distinguished physicist's exploration of the question which lies at the heart of biology, it was written for the layman, but proved one of the spurs to the birth of molecular biology and the subsequent discovery of the structure of DNA. The philosopher Karl Popper hailed it as a'beautiful and important book'by'a great man to whom I owe a personal debt for many exciting discussions'. It appears here together with Mind and Matter, his essay investigating a relationship which has eluded and puzzled philosophers since the earliest times. Schrodinger asks what place consciousness occupies in the evolution of life, and what part the state of development of the human mind plays in moral questions. Brought together with these two classics are Schrödinger's autobiographical sketches, published and translated here for the first time. They offer a fascinating fragmentary account of his life as a background to his scientific writings, making this volume a valuable additon to the shelves of scientist and layman alike.

We may regard ourselves as the most advanced species on the planet, but have we really reached our optimum design? Isn't't there always room for improvements? Before you answer, let noted evolutionary biologist George C. Williams remind you of both the exquisite adaptations and absurd maladaptations nature has bestowed upon us, the self-proclaimed'pinnacle of evolution.'Picking up where Darwin left off, Williams combines philosophical perspective and scientific method to provide a foundation for the answers to some fascinating questions. He explains why our bodies have to deteriorate so disastrously with old age. He gives us logical reasons to explain why we crave foods like sugar and fat that have been proven time and again to be detrimental to our health. And Williams single-handedly deflates our Homo sapiens sapiens ego with such insights as: Our eyesight -- it may seem superior, but not when compared to that of the invertebrate squid, whose eye has developed over time to prove more efficient than ours. And wouldn't't it make more sense to have a third eye, located on the back of the head? We could have stereoscopic vision in front and rear-vision warning us of danger sneaking up behind. Rear-view mirrors would become a thing of the past. And why stop at three eyes? This fascinating new book is markedly different from all previous work on evolutionary biology. Using the pony fish and its luminescent abdomen as the perfect evolutionary mystery, Williams explores the intricacies of nature's designs. Rather than telling us how or why the pony fish got its light, Williams explains the functional reasons why the pony fish keeps its light. He also explains why our species keeps arbitrary or malfunctioned features like the reproductive and excretory systems'sharing of parts. George C. Williams, one of today's most qualified evolutionary biologists, has written an important, entertaining, and thought-provoking addition to a science that has captivated the world for almost 150 years.
