First coined by Richard Dawkins in The Selfish Gene, a meme is any idea, behavior, or skill that can be transferred from one person to another by imitation. Susan 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.

You are just 10% human. For every one of the cells that make up the vessel that you call your body, there are nine impostor cells hitching a ride. You are not just flesh and blood, muscle and bone, brain and skin, but also bacteria and fungi. Over your lifetime, you will carry the equivalent weight of five African elephants in microbes. You are not an individual but a colony. Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies and becoming a healthy human is impossible without them.

In this captivating book, neuroscientist Shane O'Mara invites us to marvel at the benefits walking confers on our bodies and brains, and to appreciate the advantages of this uniquely human skill. From walking's evolutionary origins, traced back millions of years to life forms on the ocean floor, to new findings from cutting-edge research, he reveals how the brain and nervous system give us the ability to balance, weave through a crowded city, and run our "inner GPS" system.

Until very recently, if you were to ask most doctors, they would tell you there were only two kinds of medicine: the quack kind, and the evidence-based kind. The former is baseless, and the latter based on the best information human effort could buy. Well, Eric Topol isn't most doctors, and he suggests you entertain the notion of a third kind of medicine, one that will make the evidence-based state-of-the-art stuff look scarcely better than an alchemist trying to animate a homunculus in a jar.

Professor Jim Davies's fascinating and highly accessible book, Riveted, reveals the evolutionary underpinnings of why we find things compelling. Drawing on work from philosophy, anthropology, religious studies, psychology, economics, computer science, and biology, Davies offers a comprehensive explanation to show that in spite of the differences between the many things that we find compelling, they have similar effects on our minds and brains.

“There is no good reason why human societies should not be described and explained with the same precision and success as the rest of nature.” Thus argues evolutionary psychologist Pascal Boyer in this uniquely innovative book. Integrating recent insights from evolutionary biology, genetics, psychology, economics, and other fields, Boyer offers precise models of why humans engage in social behaviors such as forming families, tribes, and nations, or creating gender roles.

We have long attributed man's violent, aggressive, competitive nature to his animal ancestry. But what if we are just as given to cooperation, empathy, and morality by virtue of our genes? What if our behavior actually makes us apes? What kind of apes are we?

Around 250,000 people have had their genomes sequenced, and scientists expect that number to rise to one billion by 2025. Professor Steven J. Heine argues that the first thing we will do on receiving our DNA test results is to misinterpret them completely. Despite breathless (often lightly researched) media coverage about newly discovered "cancer" or "divorce" or "IQ" genes, the prospect of a DNA test forecasting how your life is going to turn out is vanishingly small.

In this eye-opening work, Graziano accessibly explores how this sense of an inner being led to empathy and formed us into social beings. The theory may point the way to engineers for building consciousness artificially. Graziano discusses what a future with artificial consciousness might be like, including both advantages and risks, and what AI might mean for our evolutionary future.

Breakthroughs in genetics present us with a promise and a predicament. The promise is that we will soon be able to treat and prevent a host of debilitating diseases. The predicament is that our newfound genetic knowledge may enable us to manipulate our nature - to enhance our genetic traits and those of our children. Although most people find at least some forms of genetic engineering disquieting, it is not easy to articulate why.

In Sleepyhead, science writer Henry Nicholls uses his own experience with chronic narcolepsy as a gateway to better understanding the cryptic, curious, and relatively uncharted world of sleep disorders. Charming, eye-opening, and deeply humanizing, Sleepyhead will help us all uncover the secrets of a good night's sleep.

Food is one of life's great joys. So why has eating become such a source of anxiety and confusion? Bee Wilson shows that in two generations the world has undergone a massive shift from traditional, limited diets to more globalized ways of eating, from bubble tea to quinoa, from Soylent to meal kits. Paradoxically, our diets are getting healthier and less healthy at the same time. For some, there has never been a happier food era than today: a time of unusual herbs, farmers' markets, and internet recipe swaps.

A Sick Life chronicles Tionne's journey from a childhood spent in and out of the hospital, told she wouldn't live to see 30 or have children, to becoming the superstar musician who is still living out her life's dream of performing. For the first time, Tionne will tell her full life story - the diagnosis, the tumultuous rise to fame, the life in the spotlight, and the hard-fought advocacy work.

Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female's pelvis and the increasing size of infants' heads precipitated a crisis for the species. Natural selection allowed for reconfiguration of hormonal cycles, entraining women with the periodicity of the moon - and imbuing women with the concept of time.

Are the ways we look at menopause all wrong? Historian Susan Mattern says yes, and The Slow Moon Climbs reveals just how wrong we have been. Taking listeners from the rainforests of Paraguay to the streets of Tokyo, Mattern draws on historical, scientific, and cultural research to reveal how our perceptions of menopause developed from prehistory to today. For most of human history, people had no word for menopause and did not view it as a medical condition. Rather, in traditional foraging and agrarian societies, it was a transition to another important life stage.

One morning, Tophs, Taylor Harris’ round-cheeked, lively 22-month-old, wakes up listless, only lifting his head to gulp down water. She rushes Tophs to the doctor, ignoring the part of herself, trained by years of therapy for generalized anxiety disorder, that tries to whisper that she’s overreacting. But at the hospital, her maternal instincts are confirmed: something is wrong with her boy, and Taylor’s life will never be the same.

Denial presents a radical new theory on the origins of our species. It was not, the authors argue, a biological leap that set humanity apart from other species, but a psychological one: namely, the uniquely human ability to deny reality in the face of inarguable evidence - including the willful ignorance of our own inevitable deaths.

Los autores del bestseller Supercerebro nos invitan modificar la predisposición genética hacia las enfermedades al cambiar nuestra dieta y nuestro estilo de vida.

Why are we the way we are? Why do some of us find it impossible to calm a quick temper or to shake anxiety? The debate has always been divided between nature and nurture, but as psychology professor Daniel P. Keating demonstrates in Born Anxious, new DNA science points to a third factor that allows us to inherit both the nature and the nurture of previous generations - with significant consequences.

In Survival of the Prettiest, Nancy Etcoff, a faculty member at Harvard Medical School and a practicing psychologist at Massachusetts General Hospital, argues that beauty is neither a cultural construction, an invention of the fashion industry, nor a backlash against feminism - it's in our biology.
