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.

Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. We have hunted them for thousands of years and scratched their icons into our mythologies. They simultaneously fill us with waves of terror, awe and affection - yet we know hardly anything about them. Whales tend to enter our awareness only when they die, struck by a ship or stranded in the surf. They evolved from land-roaming, doglike creatures into animals that move like fish and breathe like us and can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Yet despite centuries of observing whales, we know little about their evolutionary past.

What is it that makes humans human? As science and technology challenge the boundaries between life and nonlife, between organic and inorganic, this ancient question is more timely than ever. Acclaimed object-oriented philosopher Timothy Morton invites us to consider this philosophical issue as eminently political. In our relationship with nonhumans, we decide the fate of our humanity. Becoming human, claims Morton, actually means creating a network of kindness and solidarity with nonhuman beings, in the name of a broader understanding of reality.

Emma Gatewood told her family she was going on a walk and left her small Ohio hometown with a change of clothes and less than $200. The next anybody heard from her, this genteel, farm-reared, 67-year-old great-grandmother had walked 800 miles along the 2,050-mile Appalachian Trail. And in September 1955, atop Maine's Mount Katahdin, she sang the first verse of "America, the Beautiful" and proclaimed, "I said I'll do it, and I've done it."

Musician and naturalist Bernie Krause is one of the world's leading experts in natural sound, and he's spent his life discovering and recording nature's rich chorus. Searching far beyond our modern world's honking horns and buzzing machinery, he has sought out the truly wild places that remain, where natural soundscapes exist virtually unchanged from when the earliest humans first inhabited the earth.

At the age of 30, Amy Liptrot finds herself washed up back home on Orkney. Standing unstable on the island, she tries to come to terms with the addiction that has swallowed the last decade of her life. As she spends her mornings swimming in the bracingly cold sea, her days tracking Orkney's wildlife, and her nights searching the sky for the Merry Dancers, Amy discovers how the wild can restore life and renew hope.

"In mid-July of 1879, John Muir sailed for the first time through the sheer-walled fjords of Alaska's Inside Passage. 'Never before this,' he wrote, 'had I been embosomed in scenery so hopelessly beyond description.' During the previous 15 years, Muir had vanished into the north woods of Canada, walked a thousand miles from Kentucky to the Gulf of Mexico, and nested himself in the granite heart of California's Sierra Nevada mountains. Wild nature burned with volcanic intensity in the core of John Muir's soul."

Before there were mammals on land, there were dinosaurs. And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth's first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean's former top predator became its most delicious snack. Cephalopods had to step up their game.

Bernd Heinrich involves us in his quest to get inside the mind of the raven. But as animals can be spied on only by getting quite close, Heinrich adopts ravens, thereby becoming a "raven father", as well as observing them in their natural habitat. He studies their daily routines and, in the process, paints a vivid picture of the ravens' world. At the heart of this book are Heinrich's love and respect for these complex and engaging creatures, and through his keen observation and analysis we become their intimates, too.

In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field is horizontal gene transfer (HGT), or the movement of genes across species lines. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection - a type of HGT. In The Tangled Tree David Quammen chronicles these discoveries through the lives of the researchers who made them.

Since the 1987 publication of Diet for a New America, beef consumption in the United States has fallen a remarkable 19 percent. While many forces are contributing to this dramatic shift in our habits, Diet for a New America is considered to be one of the most important. Diet for a New America is a startling examination of the food we currently buy and eat in the United States and the astounding moral, economic, and emotional price we pay for it.

It's five o'clock in the morning and still dark. Swimming outside the wave break off the Catalina coast, training for her next long-distance swim (she has already crossed the English Channel twice), 17-year-old Lynne Cox senses that something is following her. She worries that it might be a great white shark.

On October 12, 1972, a plane carrying a team of young rugby players crashed into the remote, snow-peaked Andes. Out of the 45 original passengers and crew, only 16 made it off the mountain alive. For 10 excruciating weeks, they suffered deprivations beyond imagining, confronting nature head-on at its most furious and inhospitable. And to survive, these men and women not only had to keep their faith; they had to make an impossible decision: Should they eat the flesh of their dead friends?

Honeybees make decisions collectively-and democratically. Every year, faced with the life-or-death problem of choosing and traveling to a new home, honeybees stake everything on a process that includes collective fact-finding, vigorous debate, and consensus building. In fact, as world-renowned animal behaviorist Thomas Seeley reveals, these incredible insects have much to teach us when it comes to collective wisdom and effective decision making.

Dans ce livre plein de grâce, acclamé dans le monde entier, le forestier Peter Wohlleben nous apprend comment s'organise la société des arbres. Les forêts ressemblent à des communautés humaines. Les parents vivent avec leurs enfants, et les aident à grandir. Les arbres répondent avec ingéniosité aux dangers. Leur système radiculaire, semblable à un réseau internet végétal, leur permet de partager des nutriments avec les arbres malades mais aussi de communiquer entre eux.

"Ants are the most warlike of all animals, with colony pitted against colony.... Their clashes dwarf Waterloo and Gettysburg", writes Edward O. Wilson in his most finely observed work in decades. In a myrmecological tour to such far-flung destinations as Mozambique and New Guinea, the Gulf of Mexico's Dauphin Island and even his parents' overgrown yard back in Alabama, Wilson thrillingly evokes his nine-decade-long scientific obsession with more than 15,000 ant species.

In this Very Short Introduction, Nick Jenkins explores our historic investment in the exploitation of fossil energy resources and their current importance, and discusses the implications of our increasing rate of energy use. He considers the widespread acceptance by scientists and policy makers that our energy systems must reduce emissions of CO2 and other greenhouse gases, and looks forward to the radical changes in fuel technology that will be necessary to continue to provide energy supplies in a sustainable manner, and extend access across the developing world.
