John Gierach is known for his witty, trenchant observations about fly-fishing. In A Fly Rod of Your Own, Gierach once again takes us into his world and scrutinizes the art of fly-fishing. He travels to remote fishing locations where the airport is not much bigger than a garage and a flight might be held up because a passenger is running late. He sings the praises of the skilled pilots who fly to remote fishing lodges in tricky locations and bad weather.

Just in the last three years a flood of new scientific findings, driven by revelations discovered in the human genome, has provided compelling new answers to many long-standing mysteries about our most ancient ancestors, the people who first evolved in Africa and then went on to colonize the whole world. Nicholas Wade weaves this host of news-making findings together for the first time into an intriguing new history of the human story before the dawn of civilization.

You are just 10% human. For every one of the cells that make up the vessel that you call your body, there are nine impostor cells hitching a ride. You are not just flesh and blood, muscle and bone, brain and skin, but also bacteria and fungi. Over your lifetime, you will carry the equivalent weight of five African elephants in microbes. You are not an individual but a colony. Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies and becoming a healthy human is impossible without them.

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.

In December 1929, in a cave near Peking, a group of anthropologists and archaeologists that included a young French Jesuit priest named Pierre Teilhard de Chardin uncovered a prehuman skull. The find quickly became known around the world as Peking Man and was acclaimed as the missing link between erect hunting apes and our Cro-Magnon ancestors. It also became a provocative piece of evidence in the roiling debate over creationism versus evolution.

The problem of agriculture is as old as civilization. Throughout history, great societies that abused their land withered into poverty or disappeared entirely. Now we risk repeating this ancient story on a global scale due to ongoing soil degradation, a changing climate, and a rising population. But there is reason for hope. David R. Montgomery introduces us to farmers around the world at the heart of a brewing soil health revolution that could bring humanity's ailing soil back to life remarkably fast.

From the very beginning, life on Earth has been defined by war. Today, those first wars continue to be fought around and literally inside us, influencing our individual behavior and that of civilization as a whole. War between populations - whether between different species or between rival groups of humans - is seen as an inevitable part of the evolutionary process. The popular concept of "the survival of the fittest" explains and often excuses these actions.

Mankind has a distinct advantage over other terrestrial species: we talk to one another. But how did we acquire the most advanced form of communication on Earth? Daniel L. Everett, a "bombshell" linguist and "instant folk hero" (Tom Wolfe, Harper's), provides in this sweeping history a comprehensive examination of the evolutionary story of language, from the earliest speaking attempts by hominids to the more than 7,000 languages that exist today.

In his provocative new book, evolutionary biologist Jerry A. Coyne lays out in clear, dispassionate detail why the toolkit of science, based on reason and empirical study, is reliable, while that of religion - including faith, dogma, and revelation - leads to incorrect, untestable, or conflicting conclusions.

Providing a cover for our delicate and intricate bodies, the skin is our largest and fastest-growing organ. We see it, touch it, and live in it every day. It is a habitat for a mesmerizingly complex world of micro-organisms and physical functions that are vital to our health and our survival. It is also a waste removal plant, a warning system for underlying disease and a dynamic immune barrier to infection. One of the first things people see about us, skin is crucial to our sense of identity, providing us with social significance and psychological meaning.

Forget the Kama Sutra. When it comes to inventive sex acts, just look to the sea. There we find the elaborate mating rituals of armored lobsters; giant right whales engaging in a lively threesome while holding their breath; full-moon sex parties of groupers; and daily mating blitzes by blueheaded wrasse. Deep-sea squid perform inverted 69s while hermaphrodite sea slugs link up in giant sex loops.

Can urban farms reduce neighborhood crime? These may not sound like typical questions for a family physician to consider, but in Farmacology, Daphne Miller, MD, ventures out of her medical office and travels to seven innovative family farms around the country on a quest to discover the hidden connections between how we care for our bodies and how we grow our food. Miller also seeks out the perspectives of noted biomedical scientists and artfully weaves in their research, along with stories from her own practice. Farmacology offers a profound new approach to healing.

A naturalist who spent months at a time living on her own among wild creatures in remote jungles, Sy Montgomery had always felt more comfortable with animals than with people. So she gladly opened her heart to a sick piglet who had been crowded away from nourishing meals by his stronger siblings. Yet Sy had no inkling that this piglet, later named Christopher Hogwood, would not only survive but flourish.

A deft mixture of memoir and history, modern biology and behavior, In Search of Memory brings listeners from Kandel's childhood in Nazi-occupied Vienna to the forefront of one of the great scientific endeavors of the 20th century: the search for the biological basis of memory. Nobel Prize winner Eric R. Kandel intertwines the intellectual history of the powerful new science of the mind - a combination of cognitive psychology, neuroscience, and molecular biology - with his own personal quest to understand memory.

Written with the same heartwarming sentiment that made the memoir Marley & Me a runaway best seller, biologist and owl expert Stacey O'Brien chronicles her rescue of an adorable, abandoned baby barn owl - and their astonishing and unprecedented 19-year life together.

Birds are highly intelligent animals, yet their intelligence is dramatically different from our own and has been little understood. As we learn more about the secrets of bird life, we are unlocking fascinating insights into memory, relationships, game theory, and the nature of intelligence itself. The Thing with Feathers explores the astonishing homing abilities of pigeons, the good deeds of fairy-wrens, the influential flocking abilities of starlings, the deft artistry of bowerbirds, the extraordinary memories of nutcrackers, and other mysteries.

What caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

This paradigm-shifting book paints a spirited portrait of a restless people that challenges our established ways of looking at Europe's past. The story is more complex than at first believed, with new evidence suggesting that the European gene pool was stirred vigorously multiple times. Genetic clues are also enhancing our understanding of European mobility in epochs with written records, including the arrival of the Anglo-Saxons, the spread of the Slavs, and the adventures of the Vikings.

The father of cognitive neuroscience and author of Human offers a provocative argument against the common belief that our lives are wholly determined by physical processes and we are therefore not responsible for our actions.

A pioneering exploration of olfaction that upsets settled notions of how the brain translates sensory information.
