The Red Queen answers dozens of other riddles of human nature and culture -- including why men propose marriage, the method behind our maddening notions of beauty, and the disquieting fact that a woman is more likely to conceive a child by an adulterous lover than by her husband. Brilliantly written, The Red Queen offers an extraordinary new way of interpreting the human condition and how it has evolved.

    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.

    In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

    Beginning with rape, and moving on to murder, war, and genocide, Ghiglieri offers the most up-to-date, comprehensive look at the male proclivity for violence. In a strong narrative voice, he draws on the latest research and his own personal experiences—both as a primatologist and as a soldier—to explain that male violence is largely innate, a product of millions of years of evolution. In the process, he debunks many of our most clung-to, “politically correct” notions: that the differences between men and women are strictly due to socialization, that rape is really about power—not sex—and that genocide is only possible with a single madman at the helm. Well-argued, evenhanded, yet never dull, this important book illuminates the darkest impulses of the male psyche, and suggests ways for modern society to curb them.

    Females--both human and of other species--are naturally monogamous. That at least is what the study of sexual behavior after Darwin assumed, perhaps because it was written by men. Only in recent years has this version of events been challenged. Females, it has become clear, are remarkably promiscuous and have evolved an astonishing array of strategies, employed both before and after copulation, to determine exactly who will father their offspring. Tim Birkhead reveals a wonderful world in which males and females vie with each other as they strive to maximize their reproductive success. Both sexes have evolved staggeringly sophisticated ways to get what they want--often at the expense of the other. He introduces us to fish whose first encounter locks them together for life in a perpetual sexual embrace; hermaphrodites who "joust" with their reproductive organs, each trying to inseminate the other without being inseminated; and tiny flies whose seminal fluid is so toxic that it not only destroys the sperm of rival males but eventually kills the female. He explores the long and tortuous road leading to our current state of knowledge, from Aristotle's observations on chickens, to the first successful artificial insemination in the seventeenth century, to today's ingenious molecular markers for assigning paternity. And he shows how much human behavior--from the wife-sharing habits of Inuit hunters to Charlie Chaplin's paternity case--is influenced by sperm competition.Lucidly written and lavishly illustrated, with a wealth of fascinating detail and vivid examples, "Promiscuity" is the ultimate guide to the battle of the sexes.

    Humans: from the beginning will appeal to anybody who reads about these discoveries, is intrigued by them, and would like to know more about prehistory. Now brought fully up to date for 2015, Humans: from the beginning is a single-volume guide to the human past. Drawing upon expert literature and the latest multi-disciplinary research, this rigorous but accessible book traces the whole of the human story from the first apes to the first cities. The end product of five years of research, it has also been planned from the ground up to take advantage of the eBook format and ease access to visual matter, references and glossary items. Humans: from the beginning is written for the non-specialist, but it is sufficiently comprehensive in scope, rigorous in content, and well-referenced to serve as an ideal ‘one-stop’ text not only for undergraduate students of relevant disciplines, but also to postgraduates, researchers and other academics seeking to broaden their knowledge. This 32-chapter work presents an even-handed coverage of topics including: • How climate change has long played a pivotal role in our affairs and those of our ancestors. • How humans evolved from apes at a time when the apes were facing extinction. • Why the last common ancestor of humans and chimpanzees (our closest living relatives) might have been more like a human than a chimpanzee. • A possible Asian rather than African origin for the earliest humans. • Why the Neanderthals were not the dimwits of popular imagination. • How language and modern human behaviour evolved: an examination of theories including those of Robin Dunbar, Steven Mithen and Derek Bickerton. • How the small group of modern humans that eventually colonised the whole of the non-African world might have started from Arabia rather than Africa. • David Lewis-Williams’ theory that the cave art of Ice Age Europe was linked to a shamanistic belief system that might be rooted in the very architecture of the human brain. • Why the Neolithic transition from hunter-gathering to agriculture was a lengthy process, with many down sides. • Colin Renfrew’s still-controversial theory that the spread of farming communities in Neolithic times was responsible for the languages now spoken in many parts of the world. • How an ‘Urban Revolution’ replaced egalitarian farming communities with socially-stratified kingdoms and city-states in just a few millennia. • How the complex, technological societies of today have much in common with not only the earliest states but much earlier primate societies.

    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.

    This page-turning survey of the whole of terrestrial evolution sheds new light on how nervous systems evolved in animals, how the brain developed, and what it means to be human.In The Deep History of Ourselves LeDoux argues that the key to understanding all human behavior lies in viewing evolution through the prism of the first living organisms. By tracking the chain of the evolutionary timeline he shows how even the earliest single cell organisms had to solve the same problems we and our cells have to solve today in order to survive and thrive. Along the way, LeDoux explores our place in nature, how the evolution of nervous systems enchanced the ability of organisms to survive and thrive, and how the emergence of what we humans understand as consciousness made our greatest and most horrendous achievements as a species possible.

    All that mystery, all that poetry, all those complex behaviors sur­rounding human bonding leading to the most life-changing decisions we’ll ever make, are unconsciously driven by a few molecules in our brain. How does love begin? How can two strangers come to the conclusion that it would not only be pleasant to share their lives, but that they must share them? How can a man say he loves his wife, yet still cheat on her? Why do others stay in relationships even after the ro­mance fades? How is it possible to fall in love with the “wrong” person? How do people come to have a “type”? Physical attraction, jealousy, infidelity, mother-infant bonding—all the behaviors that so often leave us befuddled—are now being teased out of the fog of mystery thanks to today’s social neuroscience. Larry Young, one of the world’s leading experts in the field, and journalist Brian Alexander explain how those findings apply to you. Drawing on real human stories and research from labs around the world, The Chemistry Between Us is a bold attempt to create a “grand unified theory” of love. Some of the mind-blowing insights include:Love can get such a grip on us because it is, literally, an addiction. To a woman falling in love, a man is like her baby. Why it’s false to say society makes gender, and how it’s possible to have the body of one gender and the brain of another.Why some people are more likely to cheat than others. Why we sometimes truly can’t resist temptation.  Young and Alexander place their revelations into historical, political, and social contexts. In the pro­cess, they touch on everything from gay marriage to why single-mother households might not be good for society. The Chemistry Between Us offers powerful in­sights into love, sex, gender, sexual orientation, and family life that will prove to be enlightening, contro­versial, and thought provoking.

    Based on the most massive study of human mating ever undertaken, encompassing more than 10,000 people of all ages from thirty-seven cultures worldwide, The Evolution of Desire is the first book to present a unified theory of human mating behavior.Now in an updated edition with two new chapters by the author, The Evolution of Desire presents the latest research in the field, including starting new discoveries about the evolutionary advantages of infidelity, orgasm, and physical attractiveness.

    Morris finds remarkable similarities with captive zoo animals and looks closely at the aggressive, sexual and parental behaviour of the human species under the stresses and pressures of urban living.

    Psychologist Geoffrey Miller offers the most convincing-and radical-explanation for how and why the human mind evolved.Consciousness, morality, creativity, language, and art: these are the traits that make us human. Scientists have traditionally explained these qualities as merely a side effect of surplus brain size, but Miller argues that they were sexual attractors, not side effects. He bases his argument on Darwin's theory of sexual selection, which until now has played second fiddle to Darwin's theory of natural selection, and draws on ideas and research from a wide range of fields, including psychology, economics, history, and pop culture. Witty, powerfully argued, and continually thought-provoking, The Mating Mind is a landmark in our understanding of our own species.

    His previous books, including the Pulitzer Prize finalist The Blank Slate, have catapulted him into the limelight as one of today's most important and popular science writers. Now, in The Stuff of Thought, Pinker marries two of the subjects he knows best: language and human nature. The result is a fascinating look at how our words explain our nature. What does swearing reveal about our emotions? Why does innuendo disclose something about relationships? Pinker reveals how our use of prepositions and tenses taps into peculiarly human concepts of space and time, and how our nouns and verbs speak to our notions of matter. Even the names we give our babies have important things to say about our relations to our children and to society. With his signature wit and style, Pinker takes on scientific questions like whether language affects thought, as well as forays into everyday life: why is bulk e-mail called spam and how do romantic comedies get such mileage out of the ambiguities of dating? The Stuff of Thought is a brilliantly crafted and highly readable work that will appeal to fans of readers of everything from The Selfish Gene and Blink to Eats, Shoots & Leaves.

    Christopher Ryan and Cacilda Jethá claim that their evidence shows that before 10,000 years ago sexual constraints did not exist, paternity was not an issue, and men and women engaged in fairly free and casual bonobo-like sexual activity. Our ancestors, they argue, not only shared food, they shared sex. Are they right? Using predominantly the same sources, SEX AT DUSK takes another look at that evidence, fills in many gaps, makes many corrections, and reveals something far less candy-coated. Bringing together evolutionary biology, primatology, anthropology, and human sexuality, SEX AT DUSK shows that, rather than revealing important facts about our sexual evolution, Ryan and Jethá shroud it in a fog of misinformation and faulty logic that can only lead us further into the dark."Nearly all biologists, including yours truly, haven’t bothered to waste their time on such tripe [Sex at Dawn], although a case can be made that we have a professional responsibility to respond when the public is being so egregiously misled. Fortunately, a rebuttal to the Sex at Dawn nonsense is now available via Amazon: Sex at Dusk. It’s not only a suitable slap-down of its woeful predecessor, but Ms. Saxon even got the science right! Moreover, she has a wide-ranging and delightful mind, worth spending time with." David Barash, author of The Myth of Monogamy: fidelity and infidelity in animals and people (Holt, 2002)"Human sexuality has always been politicized, prettified, sanitized, romanticized and mythologized. For adults for whom truth is the ultimate turn-on, I recommend Lynn Saxon's insightful treatment of this eternally fascinating subject." Steven Pinker, Harvard College Professor of Psychology, Harvard University, and the author of How the Mind Works and The Blank Slate."Cleaning the Augean Stables was one of Hercules's more odious tasks, but also perhaps the most useful. Correcting the errors and misrepresentations of Sex at Dawn has been Lynn Saxon's self-imposed labor, and she does it with Herculean strength. Moreover, Sex at Dusk isn't only well-written and scientifically valid, it is great fun as well! This particular transition from Dawn to Dusk is not only natural, but much needed." David P. Barash, Professor of Psychology, University of Washington, Seattle and author of Homo mysterious: evolutionary puzzles of human nature." (Oxford University Press)

    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.Low begins by reviewing the fundamental arguments and assumptions of behavioral ecology: selfish genes, conflicts of interest, and the tendency for sexes to reproduce through different behaviors. She explains why in primate species--from chimpanzees and apes to humans--males seek to spread their genes by devoting extraordinary efforts to finding mates, while females find it profitable to expend more effort on parenting. Low illustrates these sexual differences among humans by showing that in places as diverse as the parishes of nineteenth-century Sweden, the villages of seventeenth-century China, and the forests of twentieth-century Brazil, men have tended to seek power and resources, from cattle to money, to attract mates, while women have sought a secure environment for raising children. She makes it clear, however, they have not done so simply through individual efforts or in a vacuum, but that men and women act in complex ways that involve cooperation and coalition building and that are shaped by culture, technology, tradition, and the availability of resources. Low also considers how the evolutionary drive to acquire resources leads to environmental degradation and warfare and asks whether our behavior could be channeled in more constructive ways.
