Let's face it, say Barash and Lipton: Males and females, boys and girls, men and women are different. To be sure, these differences are often heightened by distinctions in learning, cultural tradition, and social expectation, but underpinning them all is a fundamental difference that derives from biology. Throughout the natural world, males are those creatures that make sperm; females make eggs. The oft-noticed "gender gap" derives, in turn, from this "gamete gap." In "Gender Gap," Barash and Lipton (husband and wife, professor and physician, biologist and psychiatrist) explain the evolutionary aspects of male-female differences.

After describing the theory underlying the evolutionary explanation of male-female differences-in accessible, lay-person's language-they show how it applies to specific examples of animal behavior. Then, they demonstrate comparable male-female differences in the behavior of human beings cross-culturally, as well as within the United States. Barash and Lipton apply this approach to male-female differences in sexual inclinations, propensities for violence, parenting styles, and childhood experiences. They invoke much work within the traditional social sciences, such as psychology, anthropology, and sociology, which have typically ignored biological factors in the past.

Part of the highly successful revolution in scientific thought has been the recognition that evolutionary insights can illuminate behavior, no less than anatomy and physiology. This new discipline, sometimes called "sociobiology" or "evolutionary psychology," promises to help us make sense of ourselves and of our most significant others, shedding new light on what it means to be male or female. Now available in paperback with a new introduction by the authors, this accessible volume integrates work from a variety of fields, applying a new paradigm to research on gender differences.

"Barash . . . brilliantly integrat[es] science, literature, and pop culture into elegant and insightful commentaries on the most interesting and important questions of our time. A delightful read."-Michael Shermer, author of The Science of Good and Evil "Entertaining and thought-provoking."-Steven Pinker, author of The Blank Slate If we are, in part, a product of our genes, can free will exist? Incisive and engaging, this indispensable tour of evolutionary biology runs the gamut of contemporary debates, from science and religion to our place in the universe. David Barash is the author of The Myth of Monogamy and Madame Bovary's Ovaries. He lives in Redmond, Washington.

Costa Rica is the only full-fledged and totally independent country to be entirely demilitarized. Its military was abolished in 1948, with the keys to the armory handed to the Department of Education. Socially, Costa Rica is a success story. Although 94th in the world for GDP, it is in the top 10 on various measurements of health and well-being. Citizens enjoy high standards of living that include universal access to healthcare, education, and pensions. In addition, the country practices sustainable resource management, such as reforestation and the development of solar and wind power, and it expects to be carbon neutral by 2020. Hunting is illegal. 25% of the landmass is parks and reserves. The government supports universal health care, especially maternal and child health. Costa Rica even has a Blue Zone, an area where people live extraordinarily long, healthy lives. To some extent, Costa Rica is simply lucky: it was largely inaccessible, and it had virtually no precious minerals, therefore it was mostly spared the ravages of predatory colonialism. The Costa Rican people made very good social decisions, ranging from an avowed commitment to social democracy at the national level, to local land distribution to develop stable middle class farmers. But Costa Rica's neighbors have not enjoyed nearly as much peace and prosperity. It is unlikely that Costa Rica's demilitarization and its remarkable social success are coincidental; clearly, something special is going on. Through good luck, good leadership, and good decisions, Costa Rica has become arguably the sanest and most progressive country on earth. This book examines how and why Costa Rica is safe and independent without any military at all, and what the rest of us can learn from its success.

From the child taunted by her playmates to the office worker who feels stifled in his daily routine, people frequently take out their pain and anger on others, even those who had nothing to do with the original stress. The bullied child may kick her puppy, the stifled worker yells at his children: Payback can be directed anywhere, sometimes at inanimate things, animals, or other people. In Payback, the husband-and wife team of evolutionary biologist David Barash and psychiatrist Judith Lipton offer an illuminating look at this phenomenon, showing how it has evolved, why it occurs, and what we can do about it.
Retaliation and revenge are well known to most people. We all know what it is like to want to get even, get justice, or take revenge. What is new in this book is an extended discussion of redirected aggression, which occurs not only in people but other species as well. The authors reveal that it's not just a matter of yelling at your spouse "because" your boss yells at you. Indeed, the phenomenon of redirected aggression--so-called to differentiate it from retaliation and revenge, the other main forms of payback--haunts our criminal courts, our streets, our battlefields, our homes, and our hearts. It lurks behind some of the nastiest and seemingly inexplicable things that otherwise decent people do, from road rage to yelling at a crying baby. And it exists across boundaries of every kind--culture, time, geography, and even species. Indeed, it's not just a human phenomenon. Passing pain to others can be seen in birds and horses, fish and primates--in virtually all vertebrates. It turns out that there is robust neurobiological hardware and software promoting redirected aggression, as well as evolutionary underpinnings.
Payback may be natural, the authors conclude, but we are capable of rising above it, without sacrificing self-esteem and social status. They show how the various human responses to pain and suffering can be managed--mindfully, carefully, and humanely.

Do the fractious groups of Arabs and Israelis actually need each other? Can the Pentagon find new enemies to replace the USSR? Are married couples held together by a shared sense of enmity toward outside parties and even each other? Who is more likely to cultivate enemies - men or women? Is the "devil" a created enemy? Is the need for enemies psychological, sociological, or biological? These and other fascinating questions are explored by David P. Barash as he skillfully combines findings from biology, psychology, sociology, politics, history, and even literature to shed new and unexpected light on the human condition.
Barash also offers startling and controversial observations about who we are as human beings and why we seem to thrive on adversarial relationships. He argues that we create and perpetuate our "enemy system" by "passing the pain along" - from child abuse to ethnic antagonism. We may well harbor a vestigial "Neanderthal mentality," which induces us to behave in ways that were adaptive in our evolutionary past but which have broad and even global implications today. Beloved Enemies concludes with a hopeful message: We can overcome, not simply our enemies, but our need to have enemies, and our penchant for creating them. To those who seek a better understanding of the nature of conflict and to those who remain confident that we can find answers to seemingly endless and complex antagonisms, Beloved Enemies offers much food for thought.

"It's a rare author who can combine literary erudition and an easy fluency of style together with expert knowledge of psychology and evolutionary biology. David Barash adds to all this a far-seeing wisdom and a humane decency that shines through on every page. The concluding section on the senseless and dangerous futility of nuclear deterrence theory is an irrefutable tour de force which should be read by every politician and senior military officer. If only!" - Richard Dawkins From hurricanes and avalanches to diseases and car crashes, threats are everywhere. Beyond objective threats like these, there are also subjective ones: situations in which individuals threaten each other or feel threatened by society. Animals, too, make substantial use of threats. Evolution manipulates threats like these in surprising ways, leading us to question the ethics of honest versus dishonest communication. Rarely acknowledged-and yet crucially important-is the fact that humans, animals, and even plants don't only employ threats, they often respond with counter-threats that ultimately make things worse. By exploring the dynamic of threat and counter-threat, this book expands on many fraught human situations, including the fear of death, of strangers, and of "the other." Each of these leads to unique challenges, such as the specter of eternal damnation, the murderous culture of guns and capital punishment, and the emergence of right-wing nationalist populism. Most worrisome is the illusory security of deterrence, the idea that we can use the threat of nuclear war to prevent nuclear war! Threats are so widespread that we often don't realize how deeply they are ingrained in our minds or how profoundly and counter-productively they operate. Animals, humans, societies, and even countries internalize threats, behind which lie a myriad of intriguing questions: How do we know when to take a threat seriously? When do threats make things worse? Can they make things better? What can we do to use them wisely rather than destructively? In a comprehensive exploration into questions like these, noted scientist David P. Barash explains some of the most important characteristics of life as we know it.

Peace and Conflict Studies sets the standard for an accessible introduction, a comprehensive exploration, and analysis of 21st-century world events - including updated coverage of the COVID-19 pandemic, the Middle East, the Social Justice movements within the US, and Global Climate Change. The text examines current conflicts, explores the important aspects of positive peace, individual violence, nationalism, and terrorism, provides numerous visual aids, questions for further study, and suggested readings, and furnishes a comprehensive range of material to enlighten and enrich future discussion and encourage further academic pursuit. With a broad and authoritative scope, this introductory text chronicles a plethora of important global topics from pre-history to the present.

For all that science knows about the living world, notes David P. Barash, there are even more things that we don't know, genuine evolutionary mysteries that perplex the best minds in biology. Paradoxically, many of these mysteries are very close to home, involving some of the most personal aspects of being human. Homo Mysterious examines a number of these evolutionary mysteries, exploring things that we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse. Why do women experience orgasm? Why do men have a shorter lifespan than women? Why does homosexuality exist? Why does religion exist in virtually every culture? Why do we have a fondness for the arts? Why do we have such large brains? And why does consciousness exist? Readers are plunged into an ocean of unknowns-the blank spots on the human evolutionary map, the terra incognita of our own species-and are introduced to the major hypotheses that currently occupy scientists who are attempting to unravel each puzzle (including some solutions proposed here for the first time). Throughout the book, readers are invited to share the thrill of science at its cutting edge, a place where we know what we don't know, and, moreover, where we know enough to come up with some compelling and seductive explanations. Homo Mysterious is a guide to creative thought and future explorations, based on the best, most current thinking by evolutionary scientists. It captures the allure of the "not-yet-known" for those interested in stretching their scientific imaginations.

For all that science knows about the living world, there are even more things that we don't know, genuine evolutionary mysteries that perplex the best minds in biology. And paradoxically, many of these mysteries are very close to home: They involve some of the most personal aspects of being human, including such unresolved questions as why do women experience orgasm, menstruation and menopause, why do men have a shorter lifespan than women, and why does homosexuality exist? Ditto for other evolutionary mysteries of our own species: Why is religion a "cross-cultural universal," along with a fondness for the arts? Why do we have such large brains, and why does consciousness exist? Homo Mysterious examines these and other evolutionary mysteries, exploring things that we don't (yet) know about ourselves, laying out the best current hypotheses and pointing toward insights that scientists are just beginning to glimpse. Readers are invited to share the thrill of science at its exploratory margins, where we know what we don't know, and, moreover, we know enough to come up with some compelling and seductive explanations. Homo Mysterious is a guide to creative thought and future explorations, based on the most current thinking of evolutionary scientists. For those who are interested in stretching their scientific imaginations, this book will expose the lure of the not yet known.

An eye-opening look at the crossroads of religion and science, illuminating the unexpected common ground shared by biology and Buddhism. Many high-profile public intellectuals-such as the well-known "New Atheists" Richard Dawkins, Daniel Dennett, and the late Christopher Hitchens-have argued that religion and science are highly antagonistic, two views of the world that are utterly incompatible. David Barish, a renowned biologist with thirty years of experience, largely agrees with them-with one very big exception. And that exception is Buddhism. In this fascinating book, David Barash highlights an intriguing patch of common ground between scientific and religious thought, illuminating the many parallels between biology and Buddhism, allowing readers to see both in a new way. Indeed, he shows that there are numerous places where the Buddhist and biological perspectives coincide. For instance, the cornerstone ecological concept-the interconnectedness and interdependence of all things-is remarkably similar to the fundamental insight of Buddhism. Indeed, a major Buddhist text, the Avatamsaka Sutra-which consists of ten insights into the "interpenetration" between beings and their environment-could well have been written by a trained ecologist. Barash underscores other similarities, including a shared distrust of simple cause-and-effect analysis, a recognition of life as transient and as a "process" rather than permanent and static, and an appreciation of the "rightness" of nature along with a recognition of the suffering that results when natural processes are tampered with. After decades of removing predators to protect deer and elk herds, ecologists have belatedly come to a Buddhist realization that predation-and even forest fires-are natural processes that have an important place in maintaining healthy ecosystems. Buddhist Biology sheds new light on biology, Buddhism, and the remarkable ways the two perspectives come together, like powerful searchlights that offer complementary and valuable perspectives on the world and our place in it.

Human beings have long seen themselves as the center of the universe, the apple of God's eye, specially-created creatures who are somehow above and beyond the natural world. This viewpoint - a persistent paradigm of our own unique self-importance - is as dangerous as it is false. In Through a Glass Brightly, noted scientist David P. Barash explores the process by which science has, throughout time, cut humanity "down to size," and how humanity has responded. A good paradigm is a tough thing to lose, especially when its replacement leaves us feeling more vulnerable and less special. And yet, as science has progressed, we find ourselves - like it or not - bereft of many of our most cherished beliefs, confronting an array of paradigms lost. Barash models his argument around a set of "old" and "new" paradigms that define humanity's place in the universe. This new set of paradigms range from provocative revelations as to whether human beings are well designed, whether the universe has somehow been established with our species in mind (the so-called anthropic principle), whether life itself is inherently fragile, and whether Homo sapiens might someday be genetically combined with other species (and what that would mean for our self-image). Rather than seeing ourselves through a glass darkly, science enables us to perceive our strengths and weaknesses brightly and accurately at last, so that paradigms lost becomes wisdom gained. The result is a bracing, remarkably hopeful view of who we really are.
