Published to acclaim and controversy a decade ago, Sperm Wars is a revolutionary thesis about sex that turned centuries-old biological assumptions on their head. Evolution has programmed men to conquer and monopolize women while women, without ever knowing they are doing it, seek the best genetic input on offer from potential sexual partners. In this book, best-selling author Robin Baker reveals these new facts of life: ten percent of children are not fathered by their "fathers;" less than one percent of a man's sperm is capable of fertilizing anything (the rest is there to fight off all other men's sperm); "smart" vaginal mucus encourages some sperm but blocks others; and a woman is far more likely to conceive through a casual fling than through sex with her regular partner. It's no wonder that Sperm Wars is a classic of popular science writing that will surprise, entertain, and even shock.

First published in 1998, Baby Wars was the second title in a controversial trilogy of books which placed the past, present and future of human reproduction under the microscope of evolutionary biology. Baby Wars itself was focussed on parenthood and family strife, and attracted such international interest that it was translated into eight different languages. This digital English edition, with a new Preface by the authors, was released in 2017 to celebrate the book's upcoming 20th anniversary. Neither childhood nor parenthood is easy and to a greater or lesser extent babies mean wars in all families. Some of these wars are subtle and physiological, hidden from the conscious mind. Others are obvious, even aggressive, and plain for all to see. Even the most tranquil of families can experience conflict, and for some life can become virtually a running battle. But, as Baby Wars shows, there is an evolutionary rationale behind all of this disharmony. It even emerges that without many of the conflicts most people would gain less than they do from their reproductive and family experience, a paradox that forms one of the major themes of the book. The book's format, a hallmark of the whole trilogy, is first to dramatise each topic as a fictionalised case-study, then to use the perspective of evolutionary biology to interpret the behaviour shown by the drama's main characters. Topics covered range from the commonplace (such as conception campaigns, pregnancy sickness, labour pains, sleepless nights, and grandparenthood) to the illegal (such as incest and child abuse). Apart from the new Preface and an occasional minor correction or clarification the 20th Anniversary edition is a faithful digital version of the original paperback. Yet, despite the years since it was written, this release of Baby Wars is as relevant now to the understanding of the evolved drivers of reproduction and parenthood as it was at the time of the first edition. None of the scientific interpretations in the original book have been superseded in the interim. Nor, naturally, has there been any change in those instincts of men, women and children that are at the book's heart. For anybody who wishes to understand why family life and strife has evolved to be as it is, rather than how many would like it to be, the answers can be found in Baby Wars' pages.

Since the 1970s, behavioural ecologists and evolutionary biologists have been fascinated by the biological implications of sperm from different males competing for fertilization of the egg in the female reproductive tract. But until Human Sperm Competition there had never been a discussion of the phenomenon for the human species in book form, despite its relevance for a full understanding of human reproduction. The book is a pioneering analysis of the evolutionary biology of human sexuality, proposing that all aspects have been shaped by the phenomenon of sperm competition. Written 20 years ago in 1993-94, the print edition was published in 1995. Despite its age that book’s contents are as relevant now as they were two decades ago. Perhaps even more so, because since Baker and Bellis’ demonstration that human sperm competition could actually be studied in a variety of ways a number of research groups have taken up the challenge where they left off. Most of these groups have obtained results that build firmly upon Baker and Bellis’ original work. A few others created important dialogues. None though have destroyed any crucial part of the foundation first laid down in that 1995 book. But the main way in which Human Sperm Competition remains relevant to this day is that for various reasons – some cultural, some procedural, and yet others due to sheer opportunity – Baker and Bellis were able to do a number of experiments that others since have not had the opportunity to repeat. And the results of those unique experiments were presented in Human Sperm Competition and nowhere else. In the first half of the book the authors explore the role of sperm competition in the evolution of human sexual characteristics, considering for example the architecture of the female reproductive tract, the reasons for male and female infidelity and the possible biological reasons for homosexuality, masturbation and orgasm. In the second half, the mechanism of sperm competition is evaluated in detail, together with the evidence for and the implications of the authors’ own Kamikaze Sperm Hypothesis. Human Sperm Competition sets out the thesis that adopting an evolutionary approach to human reproduction exposes the subtle and sophisticated ways in which human sexual anatomy, physiology and behaviour are designed to interact. As a species, understanding this sexual legacy helps explain how we reproduce today and why problems with fertility arise. Over the years, Human Sperm Competition has become a classic in the study of human sexual biology – but although the original hardback is still in print rising costs plus perhaps its classic status have priced it beyond those students who might most wish to read its contents. This digital edition of the original 1995 publication, but at a student-friendly price, now solves this problem.

An unparalleled exploration of the mysteries underlying women's sexuality that rivals the culture-shifting Kinsey Report, from two of America's leading research psychologists Do women have sex simply to reproduce or display their affection? When University of Texas at Austin clinical psychologist Cindy M. Meston and evolutionary psychologist David M. Buss joined forces to investigate the underlying sexual motivations of women, what they found astonished them. Through the voices of real women, Meston and Buss reveal the motivations that guide women's sexual decisions and explain the deep-seated psychology and biology that often unwittingly drive women's desires—sometimes in pursuit of health or pleasure, or sometimes for darker, disturbing reasons that a woman may not fully recognize. Drawing on more than a thousand intensive interviews conducted solely for the book, as well as their pioneering research on physiological response and evolutionary emotions, Why Women Have Sex uncovers an amazingly complex and nuanced portrait of female sexuality. They delve into the use of sex as a defensive tactic against a mate's infidelity (protection), as a ploy to boost self-confidence (status), as a barter for gifts or household chores (resource acquisition), or as a cure for a migraine headache (medication). Why Women Have Sex stands as the richest and deepest psychological understanding of female sexuality yet achieved and promises to inform every woman's (and her partner's) awareness of her relationship to sex and her sexuality.

If we all want love, why is there so much conflict in our most cherished relationships? To answer this question, argues the prominent psychologist David M. Buss, we must look into our evolutionary past. 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. In this fully revised and updated edition of The Evolution of Desire, Buss has incorporated the explosion of research in the field of human mating since its original 1994 publication, from startling discoveries about the evolutionary advantages of infidelity and physical attractiveness to new findings regarding sexual orientation, the emotion of sexual disgust, and incest avoidance adaptations.

Until recently, evolutionary psychologists have considered human mating behavior to be universal and similar to other animals, painting a picture of human mating as visceral, animalistic, and instinctual. But that's not the whole story. In courtship and display, sexual competition and rivalry, we are guided by Mating Intelligence, or the range of psychological abilities designed for sexual reproduction. In this book, psychologists Glenn Geher and Scott Barry Kaufman take a fascinating tour of the intersection of r sing and intelligence by drawing on cutting-edge research on evolutionary psychology, intelligence, creativity, personality, social psychology, developmental psychology, neuroscience, epigenetics, and more. This book will change the way you think about sex, dating, love, and the human mind.

Why do men and women cheat on each other? How do men really feel when their partners have sex with other men? What worries women more -- men who turn to other women for love or men who simply want sexual variety in their lives? Can the jealousy husbands and wives experience over real or imagined infidelities be cured? Should it be? In this surprising and engaging exploration of men's and women's darker passions, David Buss, acclaimed author of The Evolution of Desire, reveals that both men and women are actually designed for jealousy. Drawing on experiments, surveys, and interviews conducted in thirty-seven countries on six continents, as well as insights from recent discoveries in biology, anthropology, and psychology, Buss discovers that the evolutionary origins of our sexual desires still shape our passions today. According to Buss, more men than women want to have sex with multiple partners. Furthermore, women who cheat on their husbands do so when they are most likely to conceive, but have sex with their spouses when they are least likely to conceive. These findings show that evolutionary tendencies to acquire better genes through different partners still lurk beneath modern sexual behavior. To counteract these desires to stray -- and to strengthen the bonds between partners -- jealousy evolved as an early detection system of infidelity in the ancient and mysterious ritual of mating. Buss takes us on a fascinating journey through many cultures, from pre-historic to the present, to show the profound evolutionary effect jealousy has had on all of us. Only with a healthy balance of jealousy and trust can we be certain of a mate's commitment, devotion, and true love.

Sex is cheap. Coupled sexual activity has become more widely available than ever. Cheap sex has been made possible by two technologies that have little to do with each other - the Pill and high-quality pornography - and its distribution made more efficient by a third technological innovation, online dating. Together, they drive down the cost of real sex, and in turn slow the development of love, make fidelity more challenging, sexual malleability more common, and have even taken a toll on men's marriageability. Cheap Sex takes readers on an extended tour inside the American mating market, and highlights key patterns that characterize young adults' experience today, including the timing of first sex in relationships, overlapping partners, frustrating returns on their relational investments, and a failure to link future goals like marriage with how they navigate their current relationships. Drawing upon several large nationally-representative surveys, in-person interviews with 100 men and women, and the assertions of scholars ranging from evolutionary psychologists to gender theorists, what emerges is a story about social change, technological breakthroughs, and unintended consequences. Men and women have not fundamentally changed, but their unions have. No longer playing a supporting role in relationships, sex has emerged as a central priority in relationship development and continuation. But unravel the layers, and it is obvious that the emergence of "industrial sex" is far more a reflection of men's interests than women's.
