Social Science Genetics

Maternal instinct - the all-consuming, utterly selfless love that mothers lavish on their children - has long been assumed to be an innate, indeed defining element of a woman's nature. But is it? In this provocative, groundbreaking audiobook, renowned anthropologist (and mother) Sarah Blaffer Hrdy shares a radical new vision of motherhood and its crucial role in human evolution. Hrdy strips away stereotypes and gender-biased myths to demonstrate that traditional views of maternal behavior are essentially wishful thinking codified as objective observation.

From the very beginning, life on Earth has been defined by war. Today, those first wars continue to be fought around and literally inside us, influencing our individual behavior and that of civilization as a whole. War between populations - whether between different species or between rival groups of humans - is seen as an inevitable part of the evolutionary process. The popular concept of "the survival of the fittest" explains and often excuses these actions.

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.

The desire for dignity is universal and powerful. It is a motivating force behind all human interaction - in families, in communities, in the business world, and in relationships at the international level. When dignity is violated, the response is likely to involve aggression, even violence, hatred, and vengeance. On the other hand, when people treat one another with dignity, they become more connected and are able to create more meaningful relationships.

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

Our Political Nature is the first book to reveal the hidden roots of our most deeply held moral values. It shows how political orientations across space and time arise from three clusters of measurable personality traits. These clusters entail opposing attitudes toward tribalism, inequality, and differing perceptions of human nature. Together, these traits are by far the most powerful cause of left-right voting, even leading people to regularly vote against their economic interests.

Just in the last three years a flood of new scientific findings, driven by revelations discovered in the human genome, has provided compelling new answers to many long-standing mysteries about our most ancient ancestors, the people who first evolved in Africa and then went on to colonize the whole world. Nicholas Wade weaves this host of news-making findings together for the first time into an intriguing new history of the human story before the dawn of civilization.

Whether looking at intelligence or emotion, cognition or behavior, science has continued to tell us that men and women are fundamentally different. Biologists claim that women are better suited to raising families or are, more gently, uniquely empathetic. Men, on the other hand, continue to be described as excelling at tasks that require logic, spatial reasoning, and motor skills. But a huge wave of research is now revealing an alternative version of what we thought we knew.

A natural history of the wilderness in our homes, from the microbes in our showers to the crickets in our basements Even when the floors are sparkling clean and the house seems silent, our domestic domain is wild beyond imagination. In Never Home Alone, biologist Rob Dunn introduces us to the nearly 200,000 species living with us in our own homes, from the Egyptian meal moths in our cupboards and camel crickets in our basements to the lactobacillus lounging on our kitchen counters. You are not alone.

Can there be freedom and free will in a deterministic world? Renowned philosopher Daniel Dennett emphatically answers "yes!" Using an array of provocative formulations, Dennett sets out to show how we alone among the animals have evolved minds that give us free will and morality. Weaving a richly detailed narrative, Dennett explains in a series of strikingly original arguments - drawing upon evolutionary biology, cognitive neuroscience, economics, and philosophy - that far from being an enemy of traditional explorations of freedom, morality, and meaning, the evolutionary perspective can be an indispensable ally.

Ever since Darwin and The Descent of Man, the existence of humans has been attributed to our intelligence and adaptability. But in Catching Fire, renowned primatologist Richard Wrangham presents a startling alternative: our evolutionary success is the result of cooking. In a groundbreaking theory of our origins, Wrangham shows that the shift from raw to cooked foods was the key factor in human evolution.

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.

For all that science knows about the living world, notes David P. Barash, there are even more things 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 we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse.

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.

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 The Lost Family, journalist Libby Copeland investigates what happens when we embark on a vast social experiment with little understanding of the ramifications. Copeland explores the culture of genealogy buffs, the science of DNA, and the business of companies like Ancestry and 23andMe, all while tracing the story of one woman, her unusual results, and a relentless methodical drive for answers that becomes a thoroughly modern genetic detective story.

How four tools enabled humanity to control its destiny What enabled us to go from simple stone tools to smartphones? How did bands of hunter-gatherers evolve into multinational empires? Listeners of Sapiens will say a cognitive revolution - a dramatic evolutionary change that altered our brains, turning primitive humans into modern ones - caused a cultural explosion. In Transcendence, Gaia Vince argues instead that modern humans are the product of a nuanced coevolution of our genes, environment, and culture that goes back into deep time.

To the modern mind, the idea of honor is outdated, sexist, and barbaric. It evokes Hamilton and Burr and pistols at dawn, not visions of a well-organized society. But for philosopher Tamler Sommers, a sense of honor is essential to living moral lives. In Why Honor Matters, Sommers argues that our collective rejection of honor has come at great cost. Reliant only on Enlightenment liberalism, the United States has become the home of the cowardly, the shameless, the selfish, and the alienated. Properly channeled, honor encourages virtues like courage, integrity, and solidarity.

Short, sassy, and bold, Mean Genes reveals that our struggles for self-improvement are, in fact, battles against our own genes - genes that helped our distant ancestors flourish, but are selfish and out of place in the modern world.

Author Brian Switek is a charming and enthusiastic osteological raconteur. In this natural and cultural history of bone, he explains where our skeletons came from, what they do inside us, and what others can learn about us when these wondrous assemblies of mineral and protein are all we've left behind.
