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.

Why do organisms grow old and die? What are the theories of aging? Does the Free Radical Theory of Aging still stack up? How do cells decide when to divide, differentiate or die? What factors accelerate the aging process? This essay takes a look at these issues and would thus be useful to students who want to know more about the processes that control cell death. The essay also documents the more extreme measures that some people have taken in the pursuit of eternal youth.

On August 5, 1949, a crew of fifteen of the U.S. Forest Service's elite airborne firefighters, the Smokejumpers, stepped into the sky above a remote forest fire in Montana wilderness. Less than an hour later, all but three were dead or fatally burned in a "blowup," an explosive 2,000 degree...

More than half a billion years ago, our world was completely covered by glaciers, a "Snowball Earth" that persisted for millions of years. Incredibly, this unimaginable cold led to the remarkable diversification of life on earth known as the Cambrian explosion. With a geologist's eye and a knack for storytelling, Graham Shields explores when and how such inhospitable conditions enabled animals to evolve, radiate, and diversify into our earliest ancestors.

If you live on a rapidly changing planet, you'd be wise to learn how it works. The giant old forests on a skinny stretch of land on the far west coast of North America have a lot to say about living in a twitchy world.

The four elements are the pillars that uphold the manifest world and anchor spirit to matter. They are associated with a wide range of spiritual entities, from small elementals to divine beings. This book explores the consciousness of the elements, which provides a system of understanding that supports most of the magic of the West and paganism. The use of the elements in a wide range of systems and practices will be examined. Much has been written about the four elements already; this book offers new teachings for newcomers and long-time practitioners alike.

This Isn’t Fine is a surprisingly funny and accessible ride through a world on the brink of collapse—and what we can do to survive it. Diving headfirst into finance and energy, culture and ecology, Taylor Ahlstrom transforms the complex systems and histories that underpin our society into relatable narratives, all while mythbusting popular delusions on everything from free-market capitalism to electric cars.

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.

Raging wildfires have devastated vast areas of California and Australia in recent years, and predictions are that we will see more of the same in coming years as a result of climate change. But this is nothing new. Andrew C. Scott tells the whole story of fire's impact on our planet's atmosphere, climate, vegetation, ecology, and the evolution of plant and animal life. It has caused mass extinctions, and it has propelled the spread of flowering plants. The exciting evidence we can now draw on has been preserved in fossilized charcoal, found in rocks hundreds of millions of years old....

A mother kisses her child's scraped knee. A father embraces his long-lost son. A dog greets its owner with desperate joy. Every culture, every species, every corner of the living world engages in these intimate acts of connection. We've been told these are merely displays of affection. But what if there’s something more? WHAT IF A KISS IS MORE THAN JUST A KISS? For the first time in human history, we are starting to see the hidden force that builds life through connection—not because we discovered something new, but because we have broken something ancient.
