Imagine being able to consume 250,000 calories daily without gaining weight. If you had the metabolism of a shrew you could. And while most of us can't hold our breath for more than a few minutes, the Weddell seal can remain underwater for a full 75 minutes! Through many amazing examples this audio discusses the mechanisms humans and other creatures have evolved to maintain survival needs.

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.

To better understand the inner workings of our bodies and to trace the origins of many of today's most common diseases, we have to turn to unexpected sources: worms, flies, and even fish.

Tucked away in Siberia, there are furry, four-legged creatures with wagging tails and floppy ears that are as docile and friendly as any lapdog. But, despite appearances, these are not dogs - they are foxes. They are the result of the most astonishing experiment in breeding ever undertaken - imagine speeding up thousands of years of evolution into a few decades. In 1959, biologists Dmitri Belyaev and Lyudmila Trut set out to do just that, by starting with a few dozen silver foxes from fox farms in the USSR and attempting to recreate the evolution of wolves into dogs in real time.

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.

By identifying the structure of DNA, the molecule of life, Francis Crick and James Watson revolutionized biochemistry and won themselves a Nobel Prize. At the time, Watson was only 24, a young scientist hungry to make his mark. His uncompromisingly honest account of the heady days of their thrilling sprint against other world-class researchers to solve one of science's greatest mysteries gives a dazzlingly clear picture of a world of brilliant scientists with great gifts, very human ambitions, and bitter rivalries.

It is widely understood that Charles Darwin’s theory of evolution completely revolutionized the study of biology. Yet, according to David Sloan Wilson, the Darwinian revolution won’t be truly complete until it is applied more broadly - to everything associated with the words “human,” “culture,” and “policy.”

Stepping effortlessly from myth to cutting-edge science, Mutants gives a brilliant narrative account of our genetic code and the captivating people whose bodies have revealed it - a French convent girl who found herself changing sex at puberty; children who, echoing Homer's Cyclops, are born with a single eye in the middle of their foreheads; a village of long-lived Croatian dwarves; one family, whose bodies were entirely covered with hair, was kept at the Burmese royal court for four generations and gave Darwin one of his keenest insights into heredity.

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.

From leading geopolitical expert and technology futurist Jamie Metzl comes a groundbreaking exploration of the many ways genetic engineering is shaking the core foundations of our lives-sex, war, love, and death. At the dawn of the genetics revolution, our DNA is becoming as readable, writable, and hackable as our information technology. But as humanity starts retooling our own genetic code, the choices we make today will be the difference between realizing breathtaking advances in human well-being and descending into a dangerous and potentially deadly genetic arms race.

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.

Locked inside the DNA of every species that ever lived are endless stories - about origins, ancestors, fate, and much more. Until recently, these secrets were completely inaccessible. But with the help of new technologies, scientists are now reading the hidden history of DNA, making remarkable discoveries about ourselves and our fellow species. Your gateway to this treasure trove of information is Unlocking the Hidden History of DNA, 12 informative and accessible lectures delivered by New York Times best-selling author Sam Kean.

The Big Ratchet is the story of the ratchets: the technologies and innovations, big and small, that propelled our species from hunters and gatherers on the savannahs of Africa to shoppers in the aisles of the supermarket. Our species long lived on the edge of starvation. Now we produce enough food for all 7 billion of us to eat nearly 3,000 calories every day. This is such an astonishing thing in the history of life as to verge on the miraculous. The Big Ratchet is the story of how it happened.

The sixth "mass extinction event" in the history of planet Earth is currently under way, with over two hundred species dying off every day. The cause of this seismic event is also the source of the single biggest threat to human life: our own inventions. But for all our talk about sea levels and biotechnology, do we really know what our future will actually look like? Will our immune systems be attacked by so-called super bugs, always evolving, and more easily spread than ever? Will the disappearance of numerous species cripple the biosphere?

In Cracking the Aging Code, theoretical biologist Josh Mitteldorf and award-winning writer and ecological philosopher Dorion Sagan reveal that evolution and aging are even more complex and breathtaking than we originally thought. Using meticulous multidisciplinary science as well as reviewing the history of our understanding about evolution, this book makes the case that aging is not something that "just happens", nor is it the result of wear and tear or a genetic inevitability.

High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It holds the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book, Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

Cuteness is an area where culture and biology get tangled up. Seeing a cute animal triggers some of the most powerful psychological instincts we have – the ones that elicit our care and protection – but there is a deeper story behind the broad appeal of Japanese cats and saccharine greetings cards. Joshua Paul Dale, a pioneer in the burgeoning field of cuteness studies, explains how the cute aesthetic spread around the globe, from pop brands to Lolita fashion, kids' cartoons and the unstoppable rise of Hello Kitty.

Control is a book about what geneticist Adam Rutherford calls “a defining idea of the twentieth century.” Inspired by Darwin’s ideas about evolution, eugenics arose in Victorian England as a theory for improving the British population, and quickly spread to America. With disarming wit and scientific precision, Rutherford explains why eugenics still figures prominently in the twenty-first century, despite its genocidal past. And he confronts insidious recurring questions, revealing the intellectual bankruptcy of the idea, and the scientific impossibility of its realization.

In The Language Puzzle, renowned archaeologist Steven Mithen puts forward a groundbreaking new account of the origins of language. Scientists have gained new insights into the first humans of 2.8 million years ago, and how numerous species flourished but only one, Homo sapiens, survives today. Drawing from this work and synthesizing research across archaeology, psychology, linguistics, genetics, and more, Mithen details a step-by-step explanation of how our human ancestors transitioned from apelike calls to words, and from words to language as we use it today.

As the planet emerged from the last ice age, a language was born between Europe and Asia, by the Black Sea. This ancient tongue, which we call Proto-Indo-European, soon exploded out of its cradle, changing and fragmenting as it went, until its offspring were spoken from Scotland to China. Today those descendants constitute the world’s largest language family, the thread that connects disparate cultures: Dante’s Inferno to the Rig Veda, The Lord of the Rings to the love poetry of Rumi. Indo-European languages are spoken by nearly half of humanity. How did this happen?
