Since Darwin's day, we've been told that sexual monogamy comes naturally to our species. 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....

From the celebrated neurobiologist and primatologist, a landmark, genre-defining examination of human behavior, both good and bad, and an answer to the question: Why do we do the things we do? Sapolsky's storytelling concept is delightful but it also has a powerful intrinsic logic: He starts by looking at the factors that bear on a person's reaction in the precise moment a behavior occurs, and then hops back in time from there, in stages, ultimately ending up at the deep history of our species and its evolutionary legacy.

Now in a third edition, Robert M. Sapolsky's acclaimed and successful Why Zebras Don't Get Ulcers features new chapters on how stress affects sleep and addiction, as well as new insights into anxiety and personality disorder and the impact of spirituality on managing stress. As Sapolsky explains, most of us do not lie awake at night worrying about whether we have leprosy or malaria. Instead, the diseases we fear-and the ones that plague us now-are illnesses brought on by the slow accumulation of damage, such as heart disease and cancer.

Neural networks, the hypothalamus, and the secrets of a woman’s mind! You probably aren’t sure what a neural network is, you likely have no clue what a hypothalamus is, but I bet you are aching to get your hands on the last one, especially if you are a dude. Never fear my friends, for this book will teach you how neural networks operate and how they are used in medical diagnostics and Forex trading. You’ll learn what a hypothalamus is and how it works, tips for keeping it healthy along with six natural ways to improve its functioning capacity.

What makes you the way you are - and what makes each of us different from everyone else? In Innate, leading neuroscientist and popular science blogger Kevin Mitchell traces human diversity and individual differences to their deepest level: in the wiring of our brains.

The father of cognitive neuroscience and author of Human offers a provocative argument against the common belief that our lives are wholly determined by physical processes and we are therefore not responsible for our actions.

We evolved for a particular environment, but our rapid social advances and mushrooming populations have created a bewildering new world. On the timescale of this dizzying change, evolution has effectively stopped, and we must rely on what has gotten us this far. By retracing the path that our distant ancestors took to get here, we can understand the stunning abilities and glaring weaknesses which we have inherited.

Through riveting personal stories and the latest research, Harvard evolutionary biologist Carole Hooven shows how testosterone drives the behavior of the sexes apart and how understanding the science behind this hormone is empowering for all.

What causes a child to grow up gay or straight? In this book, neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points to one inescapable conclusion: Sexual orientation results primarily from an interaction between genes, sex hormones, and the cells of the developing body and brain. LeVay helped create this field in 1991 with a much-publicized study in Science, where he reported on a difference in the brain structure between gay and straight men. Since then, an entire scientific discipline has sprung up around the quest for a biological explanation of sexual orientation. In this book, LeVay provides a clear explanation of where the science stands today, taking the reader on a whirlwind tour of laboratories that specialize in genetics, endocrinology, neuroscience, cognitive psychology, evolutionary psychology, and family demographics. He describes, for instance, how researchers have manipulated the sex hormone levels of animals during development, causing them to mate preferentially with animals of their own gender. LeVay also reports on the prevalence of homosexual behavior among wild animals, ranging from Graylag geese to the Bonobo chimpanzee.

Many people believe that, at its core, biological sex is a fundamental, diverging force in our development. According to this familiar story, differences between the sexes are shaped by past evolutionary pressures - women are more cautious and parenting-focused, men seek status to attract more mates - re-created in each generation by sex hormones and male and female brains. This, in turn, is the basis of supposedly entrenched inequalities in our modern societies.

The burgeoning new science of epigenetics offers a cornucopia of insights - some comforting, some frightening. For example, the male fetus may be especially vulnerable to certain common chemicals in our environment, in ways that damage not only his own sperm but also the sperm of his sons. And it’s epigenetics that causes identical twins to vary widely in their susceptibility to dementia and cancer. But here’s the good news: unlike mutations, epigenetic effects are reversible. Indeed, epigenetic engineering is the future of medicine.

You've probably seen it before: a human brain dramatically lit from the side, the camera circling it like a helicopter shot of Stonehenge, and a modulated baritone voice exalting the brain's elegant design in reverent tones... to which this book says: Pure nonsense.

Over a decade ago, as the Human Genome Project completed its mapping of the entire human genome, hopes ran high that we would rapidly be able to use our knowledge of human genes to tackle many inherited diseases, and understand what makes us unique among animals. But things didn't turn out that way.

Throughout history, even as daily life has exhibited calm and tolerance, war has never been far away, and even within societies, violence can be a threat. The Goodness Paradox gives a new and powerful argument for how and why this uncanny combination of peacefulness and violence crystallized after our ancestors acquired language in Africa a quarter of a million years ago.

What happens when we accept that everything we feel and think stems not from an immaterial spirit but from electrical and chemical activity in our brains? In this thought-provoking narrative - drawn from professional expertise as well as personal life experiences - trailblazing neurophilosopher Patricia S. Churchland grounds the philosophy of mind in the essential ingredients of biology. She reflects with humor on how she came to harmonize science and philosophy, the mind and the brain, abstract ideals and daily life.

This revised edition of Human Nature begins a new phase in the most important intellectual controversy of this generation: Is human behavior controlled by the species' biological heritage? Does this heritage limit human destiny?

With characteristic pungency and simplicity of style, the author of Sociobiology challenges old prejudices and current misconceptions about the nature-nurture debate.

Psychologists often paint a picture of human mating as visceral, instinctual. But that's not the whole story. In courtship and display, sexual competition and rivalry, we are also guided by what Glenn Geher and Scott Barry Kaufman call Mating Intelligence - a range of mental abilities that have evolved to help us find the right partner. Mating Intelligence is at work in our efforts to form, maintain, and end relationships. It guides us in flirtation, foreplay, copulation, finding and choosing a mate, and many other behaviors.

For too long, scientists have focused on the dark side of our biological heritage: our capacity for aggression, cruelty, prejudice, and self-interest. But natural selection has given us a suite of beneficial social features, including our capacity for love, friendship, cooperation, and learning. Beneath all our inventions - our tools, farms, machines, cities, nations - we carry with us innate proclivities to make a good society.

Contrary to conventional wisdom, our brains and bodies are hardwired to carry out an evolutionary mission that determines much of what we do, from life plans to everyday decisions. With an accessible tone and a healthy disregard for political correctness, this lively and eminently readable book popularizes the latest research in a cutting-edge field of study: one that turns much of what we thought we knew about human nature upside-down.

Can twins have different fathers? From the composition and function of human sex organs to the fascinating biochemistry behind sexual attraction, How Sex Works presents captivating new ideas and surprising answers to questions about contraception, fertility, circumcision, menopause, STDs, homosexuality, orgasms, and more. This is an entertaining, comprehensive exploration of culture, biology, and history that takes us far beyond our common understanding of sex.

A leading brain scientist's look at the neurobiology of pleasure-and how pleasures can become addictions. Whether eating, taking drugs, engaging in sex, or doing good deeds, the pursuit of pleasure is a central drive of the human animal. In The Compass of Pleasure Johns Hopkins neuroscientist David J. Linden explains how pleasure affects us at the most fundamental level: in our brain.

The Self Illusion provides a fascinating examination of how the latest science shows that our individual concept of a self is in fact an illusion. Most of us believe that we possess a self - an internal individual who resides inside our bodies, making decisions, authoring actions and possessing free will. The feeling that a single, unified, enduring self inhabits the body is compelling and inescapable. But that sovereignty of the self is increasingly under threat from science as our understanding of the brain advances.

A riveting investigation of the myriad ways that parasites control how other creatures - including humans - think, feel, and act. These tiny organisms can live only inside another animal, and, as McAuliffe reveals, they have many evolutionary motives for manipulating their host's behavior. Far more often than appreciated, these puppeteers orchestrate the interplay between predator and prey.

Where did I come from? Why do I have two arms but just one head? How is my left leg the same size as my right one? Why are the fingerprints of identical twins not identical? How did my brain learn to learn? Why must I die? Questions like these remain biology's deepest and most ancient challenges. They force us to confront a fundamental biological problem: How can something as large and complex as a human body organize itself from the simplicity of a fertilized egg?

Scientists have long counseled against interpreting animal behavior in terms of human emotions, warning that such anthropomorphizing limits our ability to understand animals as they really are. Yet what are we to make of a female gorilla in a German zoo who spent days mourning the death of her baby? Or a wild female elephant who cared for a younger one after she was injured by a rambunctious teenage male?

Why are conditions like autism, asthma, obesity, and allergies exploding at unprecedented rates? Why are we living longer, getting smarter, having far fewer kids? If Darwin were alive today, how would he explain this new world?
