Since the birth of civilization, human beings have manipulated other life-forms. We have selectively bred plants and animals for thousands of years to maximize agricultural production and cater to our tastes in pets. The observation of the creation of artificial animal and plant variants was a key stimulant for Charles Darwin's theory of evolution. The ability to directly engineer the genomes of organisms first became possible in the 1970s, when the gene for human insulin was introduced into bacteria.

We evolved to eat berries rather than bagels, to live in mud huts rather than condos, to sprint barefoot rather than play football - or did we? Are our bodies and brains truly at odds with modern life? Although it may seem as though we have barely had time to shed our hunter-gatherer legacy, biologist Marlene Zuk reveals that the story is not so simple. Popular theories about how our ancestors lived - and why we should emulate them - are often based on speculation, not scientific evidence. Armed with a razor-sharp wit and brilliant, eye-opening research, Zuk takes us to the cutting edge of biology to show that evolution can work much faster than was previously realized.

An entertaining and enlightening exploration of why waste matters, this cultural history explores an often ignored subject matter and makes a compelling argument for a deeper understanding of human and animal waste. Approaching the subject from a variety of perspectives - evolutionary, ecological, and cultural - this examination shows how integral excrement is to biodiversity, agriculture, public health, food production and distribution, and global ecosystems.

The Galapagos were once known to the sailors and pirates who encountered them as Las Encantadas: the enchanted islands, home to exotic creatures and dramatic volcanic scenery. In The Galapagos, science writer Henry Nicholls offers a lively natural and human history of the archipelago, charting its evolution from deserted wilderness to scientific resource (made famous by Charles Darwin) and global ecotourism hot spot.

Could extinct species, like mammoths and passenger pigeons, be brought back to life? The science says yes. In How to Clone a Mammoth, Beth Shapiro, evolutionary biologist and pioneer in "ancient DNA" research, walks listeners through the astonishing and controversial process of de-extinction.

There is a human genetic fluke that is surprisingly common, due to a change in a key pair of chromosomes. In the normal condition the two look the same, but in this disorder one is malformed and shrunken beyond recognition. The result is a shortened life span, higher mortality at all ages, an inability to reproduce, premature hair loss, and brain defects variously resulting in attention deficit, hyperactivity, conduct disorder, hypersexuality, and an enormous excess of both outward and self-directed aggression. It is called maleness.

Humans are awesome. Our brains are gigantic, seven times larger than they should be for the size of our bodies. The human brain uses 25 percent of all the energy the body requires each day. And it became enormous in a very short amount of time in evolution, allowing us to leave our cousins, the great apes, behind. So the human brain is special, right? Wrong, according to Suzana Herculano-Houzel. Humans have developed cognitive abilities that outstrip those of all other animals but not because we are evolutionary outliers.

Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built - and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.

A panoramic overview of biotechnologies that can endlessly boost human capabilities and the drastic changes these "superhuman" traits could trigger. Biotechnology is moving fast. In the coming decades, advanced pharmaceuticals, bioelectronics, and genetic interventions will be used not only to heal the sick but to boost human physical and mental performance to unprecedented levels.

Most people know that Gregor Mendel, the Moravian monk who patiently grew his peas in a monastery garden, shaped our understanding of inheritance. But people might not know that Mendel's work was ignored in his own lifetime, even though it contained answers to the most pressing questions raised by Charles Darwin's revolutionary book, On Origrin of the Species, published only a few years earlier. Mendel's single chance of recognition failed utterly, and he died a lonely and disappointed man.

How did species wind up where they are today? Scientists have long conjectured that plants and animals dispersed throughout the world by drifting on large landmasses as they broke up, but in The Monkey’s Voyage, biologist Alan de Queiroz offers a radical new theory that displaces this passive view.

We have long fantasized about finding life on planets other than our own. Yet even as we become aware of the vast expanses beyond our solar system, it remains clear that Earth is exceptional. The question is: Why? In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is what makes it uniquely able to support life, and it is nothing short of luck that made such conditions possible. The four-billion-year stretch of good weather that our planet has experienced is statistically so unlikely that chances are slim that we will ever encounter intelligent extraterrestrial others.

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.

In this startling study of human emotion, Dacher Keltner investigates an unanswered question of human evolution: If humans are hardwired to lead lives that are "nasty, brutish, and short," why have we evolved with positive emotions like gratitude, amusement, awe, and compassion that promote ethical action and cooperative societies? Born to Be Good takes us on a journey through scientific discovery, personal narrative, and Eastern philosophy.

Survival of the fittest or survival of the nicest? Since the dawn of time man has contemplated the mystery of altruism, but it was Darwin who posed the question most starkly. From the selfless ant to the stinging bee to the man laying down his life for a stranger, evolution has yielded a goodness that in theory should never be. Set against the sweeping tale of 150 years of scientific attempts to explain kindness, The Price of Altruism tells for the first time the moving story of the eccentric American genius George Price (1922-1975), as he strives to answer evolution's greatest riddle.

Without our domesticated plants and animals, human civilization as we know it would not exist. We would still be living at subsistence level as hunter-gatherers if not for domestication. It is no accident that the cradle of civilization - the Middle East - is where sheep, goats, pigs, cattle, and cats commenced their fatefully intimate associations with humans.

The question of teaching evolution in the public schools is a continuing and frequently heated political issue in America. From Tennessee's Scopes Trial in 1925 to recent battles that have erupted in Louisiana, Kansas, Ohio, and countless other localities, the critics and supporters of evolution have fought nonstop over the role of science and religion in American public life. In American Genesis, Jeffrey P. Moran explores the ways in which the evolution debate has reverberated beyond the confines of state legislatures and courthouses.

John Tyler Bonner, one of our most distinguished and insightful biologists, here challenges a central tenet of evolutionary biology. In this concise, elegantly written book, he makes the bold and provocative claim that some biological diversity may be explained by something other than natural selection. With his customary wit and accessible style, Bonner makes an argument for the underappreciated role that randomness - or chance - plays in evolution.

Despite extensive evidence highlighting the influence of genetics in the business world, this critical connection has been glossed over by corporate leaders and management gurus. Now, for the first time, author Scott Shane explains why genes matter, and how an understanding of their relationship to behavior is of vital importance to employers, employees, and policy makers.

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.
