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.

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.

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.

From the family to the workplace to the marketplace, every facet of our lives is shaped by cooperative interactions. Yet everywhere we look, we are confronted by proof of how difficult cooperation can be - snarled traffic, polarized politics, overexploited resources, social problems that go ignored. The benefits to oneself of a free ride on the efforts of others mean that collective goals often are not met. But compared to most other species, people actually cooperate a great deal. Why is this?

The current controversy over teaching evolution in the public schools has grabbed front-page headlines and topped news broadcasts all across the United States. In the Beginning investigates the movement that has ignited debate in state legislatures and at school board meetings. Reaching back to the origins of antievolutionism in the 1920s, and continuing to the promotion of intelligent design today, Michael Lienesch skillfully analyzes one of the most formidable political movements of the 20th century.

In Strange Bedfellows, David P. Barash and Judith Eve Lipton look at how biology actually promotes monogamy in some species and how these lessons apply to human beings. An accessible work of science that is relevant to our intimate daily life, Strange Bedfellows will reassure some people, surprise others, and engage everyone.

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.

An extraterrestrial colony, in some form, may already exist, just awaiting discovery. But the greatest impediment to such an important scientific discovery may not be technological, but political. No scientific endeavor can be launched without a budget, and matters of money are within the arena of politicians. Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities.

I had a crazy uncle, like most everyone does. Many of his stories were about a big hairy monster that lived in the woods behind his cabin in the woods. He called the monster Bigfoot, a name I thought he made up when I was eight years old because I hadn’t heard the word before that. He had a Bigfoot encounter and was worried about abduction and attack all the time. My story takes place while I was in college, but it started way before that when Uncle Chip was still alive.

August Weismann is regarded by many biologists, including Ernst Mayr from Harvard University, to be second only to Charles Darwin for progressing our understanding of evolution by natural selection. In this book, excerpted from the larger commemorative tome Darwin and Modern Science, edited by A. C. Seward and others, Weismann tackles many of the difficult questions confronting natural selection. In the process, Weismann offers a penetrating critique of Lamarck and provides the listener with rich and robust understanding of evolutionary theory.
