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.

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

In Zero Waste Home, Bea Johnson shares the story of how she simplified her life by reducing her waste. Today, Bea, her husband, Scott, and their two young sons produce just one quart of garbage a year, and their overall quality of life has changed for the better. They now have more time together, they've cut their annual spending by a remarkable 40 percent, and they are healthier than they've ever been.

The world's worst air disaster happened more than 40 years ago on a remote Atlantic Ocean island, when two fully loaded 747 passenger jets collided after a horrendous series of human errors. One of the jets, KLM Flight 4805, was traveling more than 150 miles an hour and was within seconds of lifting off when it crashed into Pan Am Flight 1736 taxiing in its path. The loss of lives was staggering - 583 dead. The crash happened after a lengthy series of major and minor human errors. In the intervening years, has aviation advanced to the point that such a disaster can't happen again?

In this entertaining book, Donald R. Prothero explores the astonishing connections between climate and life through the ages, telling the remarkable stories of the scientists who made crucial discoveries. Journeying through the intertwined evolution of climate and life, he tackles questions such as: Why do we have phytoplankton to thank for the air we breathe? What kind of climate was necessary for the rise of the dinosaurs-or the mammals, their successors? When and how have climatic changes caused mass extinctions?

We all want to live more healthily and ethically. This book is for anyone interested in veganism, its ideals, and what even nonvegans can learn from its practice. Through a personal and often irreverent lens, the authors explore a variety of contemporary topics related to animal use: from the basics of vegan logic to politics, economics, love, and other aspects of being human, each chapter draws you into a thought-provoking conversation about your daily ethical decisions.

Ants number in the ten quadrillions, and they have been here since the Jurassic era. Inside an anthill, you'll find high drama worthy of a royal court; and between colonies, high-stakes geopolitical intrigue is afoot. Just like us, ants grow crops, raise livestock, tend their young and infirm, and make vaccines. And, just like us, ants have a dark side: They wage war, despoil environments, and enslave rivals - but also rebel against their oppressors.

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.

In 1978, the first group of space shuttle astronauts was introduced to the world - 29 men and six women who would carry NASA through the most tumultuous years of the space shuttle program. Among them was USAF Colonel Mike Mullane, who, in his memoir Riding Rockets, strips the heroic veneer from the astronaut corps and paints them as they are - human.

That the dog evolved from the wolf is an accepted fact of evolution and history, but the question of how wolf became dog has remained a mystery, obscured by myth and legend. How the Dog Became the Dog posits that dog was an evolutionary inevitability in the nature of the wolf and its human soul mate. The natural temperament and social structure of humans and wolves are so similar that as soon as they met on the trail they recognized themselves in each other.

Block by Block offers an original perspective on thermodynamic science and history based on the three approaches of a practicing engineer, academician, and historian. The book synthesizes and gathers into one accessible volume a strategic range of foundational topics involving the atomic theory, energy, entropy, and the laws of thermodynamics.

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.

New from best-selling author Mark Shepard! Written as a companion to the best seller Restoration Agriculture, this book will help farmers capture water in areas they want to and avoid having water flow immediately to the low point. The result? Less water expense, healthier crops and livestock, and less erosion...just to name a few.

For 200 years, a noble Venetian family has suffered from an inherited disease that strikes their members in middle age, stealing their sleep, eating holes in their brains, and ending their lives in a matter of months. In Papua New Guinea, a primitive tribe is nearly obliterated by a sickness whose chief symptom is uncontrollable laughter. Across Europe, millions of sheep rub their fleeces raw before collapsing. What these strange conditions share is their cause: prions.

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.

We have long attributed man's violent, aggressive, competitive nature to his animal ancestry. But what if we are just as given to cooperation, empathy, and morality by virtue of our genes? What if our behavior actually makes us apes? What kind of apes are we?

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.

Growing up in California, J. Craig Venter didn't appear to have much of a future. An unremarkable student, he nearly flunked out of high school. After being drafted into the army, he enlisted in the Navy and went to Vietnam, where the life-and-death struggles he encountered as a medic piqued his interest in science and medicine. After pursuing his advanced degrees, Venter quickly established himself as a brilliant and outspoken scientist.

All social groups have ideals for behavior, even though ethics vary among different cultures and among individuals within each culture. In trying to understand why, Churchland brings together an understanding of the influences of nature and nurture. She looks to evolution to elucidate how, from birth, our brains are configured to form bonds, to cooperate, and to care. Conscience delves into scientific studies, particularly the fascinating work on twins, to deepen our understanding of whether people have a predisposition to embrace specific ethical stands.

Teeming with unsuspected life, an extraordinary, interconnected ecosystem deep below the waves has a huge effect on our daily lives, influencing climate and weather systems, with the potential for much more—good or bad, depending on how it is exploited. Currently, the fantastic creatures that live in the deep—many of them incandescent in a world without light—and its formations capture and trap vast quantities of carbon that would otherwise poison our atmosphere, and novel bacteria as yet undiscovered hold the promise of potent new medicines.
