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.

    But natural selection has given us a suite of beneficial social features, including our capacity for love, friendship, cooperation, and learning. Beneath all of our inventions -- our tools, farms, machines, cities, nations -- we carry with us innate proclivities to make a good society.In Blueprint, Nicholas A. Christakis introduces the compelling idea that our genes affect not only our bodies and behaviors, but also the ways in which we make societies, ones that are surprisingly similar worldwide.With many vivid examples -- including diverse historical and contemporary cultures, communities formed in the wake of shipwrecks, commune dwellers seeking utopia, online groups thrown together by design or involving artificially intelligent bots, and even the tender and complex social arrangements of elephants and dolphins that so resemble our own -- Christakis shows that, despite a human history replete with violence, we cannot escape our social blueprint for goodness.In a world of increasing political and economic polarization, it's tempting to ignore the positive role of our evolutionary past. But by exploring the ancient roots of goodness in civilization, Blueprint shows that our genes have shaped societies for our welfare and that, in a feedback loop stretching back many thousands of years, societies are still shaping our genes today.

    Just as evolutionary biologists study why we are hungry (to motivate us to eat) or why sex is enjoyable (to motivate us to procreate), they are now searching for the very nature of humanity.In The Science of Good and Evil, science historian Michael Shermer explores how humans evolved from social primates to moral primates; how and why morality motivates the human animal; and how the foundation of moral principles can be built upon empirical evidence.Along the way he explains the implications of scientific findings for fate and free will, the existence of pure good and pure evil, and the development of early moral sentiments among the first humans. As he closes the divide between science and morality, Shermer draws on stories from the Yanamamö, infamously known as the "fierce people" of the tropical rain forest, to the Stanford studies on jailers' behavior in prisons. The Science of Good and Evil is ultimately a profound look at the moral animal, belief, and the scientific pursuit of truth.

    Gould's brilliant, funny, engaging prose dissects the motivations behind those who would judge intelligence, and hence worth, by cranial size, convolutions, or score on extremely narrow tests. How did scientists decide that intelligence was unipolar and quantifiable? Why did the standard keep changing over time? Gould's answer is clear and simple: power maintains itself. European men of the 19th century, even before Darwin, saw themselves as the pinnacle of creation and sought to prove this assertion through hard measurement. When one measure was found to place members of some "inferior" group such as women or Southeast Asians over the supposedly rightful champions, it would be discarded and replaced with a new, more comfortable measure. The 20th-century obsession with numbers led to the institutionalization of IQ testing and subsequent assignment to work (and rewards) commensurate with the score, shown by Gould to be not simply misguided--for surely intelligence is multifactorial--but also regressive, creating a feedback loop rewarding the rich and powerful. The revised edition includes a scathing critique of Herrnstein and Murray's The Bell Curve, taking them to task for rehashing old arguments to exploit a new political wave of uncaring belt tightening. It might not make you any smarter, but The Mismeasure of Man will certainly make you think.--Rob LightnerThis edition is revised and expanded, with a new introduction

    This introductory book provides an overview of the key theoretical principles of human sociobiology and evolutionary psychology and shows how they illuminate the ways humans think and behave. The book takes as one of its main premises the idea that we think, feel, and act in ways that once enhanced the reproductive success of our ancestors.The book covers fundamental issues such as the origins and function of sexual reproduction, mating behavior, human mate choice, patterns of violence in families, altruistic behavior, the evolution of brain size and the origins of language, the modular mind, and the relationship between genes and culture. It also examines the larger implications of Darwinism for how we view ourselves as a species and our sense of ourselves as a moral animal. The book includes a valuable historical introduction to evolutionary theories of behavior and concludes with an examination of the social and political ramifications of evolutionary thought. It contains numerous diagrams and illustrations, comprehensive references, summaries, and suggestions for further reading.

    Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe--descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished. Ever since the first Neanderthal bones were identified in 1856, scientists have been vexed by the question, why did modern humans survive while their evolutionary cousins went extinct?The Invaders musters compelling evidence to show that the major factor in the Neanderthals' demise was direct competition with newly arriving humans. Drawing on insights from the field of invasion biology, which predicts that the species ecologically closest to the invasive predator will face the greatest competition, Pat Shipman traces the devastating impact of a growing human population: reduction of Neanderthals' geographic range, isolation into small groups, and loss of genetic diversity.But modern humans were not the only invaders who competed with Neanderthals for big game. Shipman reveals fascinating confirmation of humans' partnership with the first domesticated wolf-dogs soon after Neanderthals first began to disappear. This alliance between two predator species, she hypothesizes, made possible an unprecedented degree of success in hunting large Ice Age mammals--a distinct and ultimately decisive advantage for humans over Neanderthals at a time when climate change made both groups vulnerable.

    Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.The fossil record is now one of the strongest lines of evidence for evolution. In this engaging and richly illustrated book, Donald R. Prothero weaves an entertaining though intellectually rigorous history out of the transitional forms and series that dot the fossil record. Beginning with a brief discussion of the nature of science and the "monkey business of creationism," Prothero tackles subjects ranging from flood geology and rock dating to neo-Darwinism and macroevolution. He covers the ingredients of the primordial soup, the effects of communal living, invertebrate transitions, the development of the backbone, the reign of the dinosaurs, the mammalian explosion, and the leap from chimpanzee to human. Prothero pays particular attention to the recent discovery of "missing links" that complete the fossil timeline and details the debate between biologists over the mechanisms driving the evolutionary process.Evolution is an absorbing combination of firsthand observation, scientific discovery, and trenchant analysis. With the teaching of evolution still an issue, there couldn't be a better moment for a book clarifying the nature and value of fossil evidence. Widely recognized as a leading expert in his field, Prothero demonstrates that the transformation of life on this planet is far more awe inspiring than the narrow view of extremists.

    Using the latest genetic and anthropological data, Spencer Wells demonstrates that although humankind's decision to control our own food supply is what propelled us into the modern world, it had many downsides that we're just now beginning to recognize.

    Drawing on his breakthrough research in comparative neuroscience, Terrence Deacon offers a wealth of insights into the significance of symbolic thinking: from the co-evolutionary exchange between language and brains over two million years of hominid evolution to the ethical repercussions that followed man's newfound access to other people's thoughts and emotions.Informing these insights is a new understanding of how Darwinian processes underlie the brain's development and function as well as its evolution. In contrast to much contemporary neuroscience that treats the brain as no more or less than a computer, Deacon provides a new clarity of vision into the mechanism of mind. It injects a renewed sense of adventure into the experience of being human.

    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.

    Their struggle to survive on the open grasslands required a shift from individualism to a new form of collectivism, which forever altered the way our mind works. It changed the way we fight and our proclivity to make peace, it changed the way we lead and the way we follow, it made us innovative but not inventive, it created a new kind of social intelligence, and it led to new sources of life satisfaction.In The Social Leap, William von Hippel lays out this revolutionary hypothesis, tracing human development through three critical evolutionary inflection points to explain how events in our distant past shape our lives today. From the mundane, such as why we exaggerate, to the surprising, such as why we believe our own lies and why fame and fortune are as likely to bring misery as happiness, the implications are far reaching and extraordinary.Blending anthropology, biology, history, and psychology with evolutionary science, The Social Leap is a fresh and provocative look at our species that provides new clues about who we are, what makes us happy, and how to use this knowledge to improve our lives.

    The meme is also one of the most important--and controversial--concepts to emerge since 'The Origin of the Species' appeared nearly 150 years ago.In 'The Meme Machine' Susan Blackmore boldly asserts: "Just as the design of our bodies can be understood only in terms of natural selection, so the design of our minds can be understood only in terms of memetic selection." Indeed, Blackmore shows that once our distant ancestors acquired the crucial ability to imitate, a second kind of natural selection began, a survival of the fittest amongst competing ideas and behaviors. Ideas and behaviors that proved most adaptive - making tools, for example, or using language--survived and flourished, replicating themselves in as many minds as possible. These memes then passed themselves on from generation to generation by helping to ensure that the genes of those who acquired them also survived and reproduced. Applying this theory to many aspects of human life, Blackmore offers brilliant explanations for why we live in cities, why we talk so much, why we can't stop thinking, why we behave altruistically, how we choose our mates, and much more.With controversial implications for our religious beliefs, our free will, our very sense of "self," 'The Meme Machine' offers a provocative theory everyone will soon be talking about.

    Here is the Naked Ape at his most primal in love, at work, at war. Meet man as he really is: relative to the apes, stripped of his veneer as we see him courting, making love, sleeping, socializing, grooming, playing. The Naked Ape takes its place alongside Darwin’s Origin of the Species, presenting man not as a fallen angel, but as a risen ape, remarkable in his resilience, energy and imagination, yet an animal nonetheless, in danger of forgetting his origins. With its penetrating insights on man's beginnings, sex life, habits and our astonishing bonds to the animal kingdom, The Naked Ape is a landmark, at once provocative, compelling and timeless.

    But how did we acquire the most advanced form of communication on Earth? Daniel L. Everett, a “bombshell” linguist and “instant folk hero” (Tom Wolfe, Harper’s), provides in this sweeping history a comprehensive examination of the evolutionary story of language, from the earliest speaking attempts by hominids to the more than seven thousand languages that exist today.Although fossil hunters and linguists have brought us closer to unearthing the true origins of language, Daniel Everett’s discoveries have upended the contemporary linguistic world, reverberating far beyond academic circles. While conducting field research in the Amazonian rainforest, Everett came across an age-old language nestled amongst a tribe of hunter-gatherers. Challenging long-standing principles in the field, Everett now builds on the theory that language was not intrinsic to our species. In order to truly understand its origins, a more interdisciplinary approach is needed—one that accounts as much for our propensity for culture as it does our biological makeup.Language began, Everett theorizes, with Homo Erectus, who catalyzed words through culturally invented symbols. Early humans, as their brains grew larger, incorporated gestures and voice intonations to communicate, all of which built on each other for 60,000 generations. Tracing crucial shifts and developments across the ages, Everett breaks down every component of speech, from harnessing control of more than a hundred respiratory muscles in the larynx and diaphragm, to mastering the use of the tongue. Moving on from biology to execution, Everett explores why elements such as grammar and storytelling are not nearly as critical to language as one might suspect.In the book’s final section, Cultural Evolution of Language, Everett takes the ever-debated “language gap” to task, delving into the chasm that separates “us” from “the animals.” He approaches the subject from various disciplines, including anthropology, neuroscience, and archaeology, to reveal that it was social complexity, as well as cultural, physiological, and neurological superiority, that allowed humans—with our clawless hands, breakable bones, and soft skin—to become the apex predator.How Language Began ultimately explains what we know, what we’d like to know, and what we likely never will know about how humans went from mere communication to language. Based on nearly forty years of fieldwork, Everett debunks long-held theories by some of history’s greatest thinkers, from Plato to Chomsky. The result is an invaluable study of what makes us human.
