The earthworm may be small, spineless, and blind, but its impact on the ecosystem is profound. It ploughs the soil, fights plant diseases, cleans up pollution, and turns ordinary dirt into fertile land. Who knew? In her witty, offbeat style, Stewart shows that much depends on the actions of the lowly worm. Charles Darwin devoted his last years to the meticulous study of these creatures, praising their remarkable abilities. With the august scientist as her inspiration, Stewart investigates the worm's subterranean realm, talks to oligochaetologists—the unsung heroes of earthworm science—who have devoted their lives to unearthing the complex life beneath our feet, and observes the thousands of worms in her own garden. From the legendary giant Australian worm that stretches to ten feet in length to the modest nightcrawler that wormed its way into the heart of Darwin's last book to the energetic red wigglers in Stewart's compost bin, The Earth Moved gives worms their due and exposes their hidden and extraordinary universe. This book is for all of us who appreciate Mother Nature's creatures, no matter how humble.

    But evolutionary biologists also point out many examples of contingency, cases where the tiniest change--a random mutation or an ancient butterfly sneeze--caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary freaks? And what does that say about life on other planets?Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be.Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

    In Never Home Alone, biologist Rob Dunn introduces us to the nearly 200,000 species living with us in our own homes, from the Egyptian meal moths in our cupboards and camel crickets in our basements to the lactobacillus lounging on our kitchen counters. You are not alone. Yet, as we obsess over sterilizing our homes and separating our spaces from nature, we are unwittingly cultivating an entirely new playground for evolution. These changes are reshaping the organisms that live with us -- prompting some to become more dangerous, while undermining those species that benefit our bodies or help us keep more threatening organisms at bay. No one who reads this engrossing, revelatory book will look at their homes in the same way again.

    In fact the currently accepted history of life on Earth is flawed and out of date. Now two pioneering scientists, one already an award-winning popular author, deliver an eye-opening narrative that synthesizes a generation's worth of insights from new research.Writing with zest, humor, and clarity, Ward and Kirschvink show that many of our long-held beliefs about the history of life are wrong. Three central themes emerge from the narrative. First, the development of life was not a stately, gradual process: Catastrophe, argue Ward and Kirschvink, shaped life's history more than all other forces combined-from notorious events like the sudden extinction of dinosaurs to recently discovered ones like "Snowball Earth" and the "Great Oxygenation Event." One startling possibility: that life arrived on Earth from Mars. Second, life consists of carbon, but three other molecules have determined how it evolved: oxygen, carbon dioxide, and hydrogen sulfide are carbon's silent partners. Third, ever since Darwin we have thought of evolution in terms of species. Yet it is the evolution of ecosystems-from deep-ocean vents to rainforests-that has formed the living world as we know it.Drawing on their years of experience in paleontology, biology, chemistry, and astrobiology, Ward and Kirschvink tell a story of life on Earth that is at once too fabulous to imagine and too familiar to dismiss. And in a provocative coda, they assemble discoveries from the latest cutting-edge research to imagine how the history of life might unfold deep into the future.

    Back in the 1990s--working undercover with his colleagues in the environmental movement--he would descend on trial sites of genetically modified crops at night and hack them to pieces. Two decades later, most people around the world--from New York to China--still think that 'GMO' foods are bad for their health or likely to damage the environment. But Mark has changed his mind. This book explains why.In 2013, in a world-famous recantation speech, Mark apologised for having destroyed GM crops. He spent the subsequent years touring Africa and Asia, and working with plant scientists who are using this technology to help smallholder farmers in developing countries cope better with pests, diseases and droughts.This book lifts the lid on the anti-GMO craze and shows how science was left by the wayside as a wave of public hysteria swept the world. Mark takes us back to the origins of the technology and introduces the scientific pioneers who invented it. He explains what led him to question his earlier assumptions about GM food, and talks to both sides of this fractious debate to see what still motivates worldwide opposition today. In the process he asks--and answers--the killer question: how did we all get it so wrong on GMOs?

    Using the latest genetic and anthropological data, Spencer Wells demonstrates that although humankind's decision to control our own food supply is what propelled us into the modern world, it had many downsides that we're just now beginning to recognize.

    Could such an apparently impotent and mindless force really have built the sophisticated molecular devices found throughout nature? The answer, he insists, is no. The only common-sense explanation is intelligent design

    Looking at the organisms that have made all this possible gives us a new way of understanding how we got here--and perhaps of thinking about where we're going. Instead of a history of which great scientists had which great ideas, this story of passionflowers and hawkweeds, of zebra fish and viruses, offers a bird's (or rodent's) eye view of the work that makes science possible.Mixing the celebrities of genetics, like the fruit fly, with forgotten players such as the evening primrose, the book follows the unfolding history of biological inheritance from Aristotle's search for the "universal, absolute truth of fishiness" to the apparently absurd speculations of eighteenth-century natural philosophers to the spectacular findings of our day--which may prove to be the absurdities of tomorrow.The result is a quirky, enlightening, and thoroughly engaging perspective on the history of heredity and genetics, tracing the slow, uncertain path--complete with entertaining diversions and dead ends--that led us from the ancient world's understanding of inheritance to modern genetics.

    The Big Questions series is designed to let renowned experts address the 20 most fundamental and frequently asked questions of a major branch of science or philosophy. Each 3,000-word essay simply and concisely examines a question that has eternally perplexed enquiring minds, and provides answers based on the latest research. This ambitious project is a unique distillation of humanity's best ideas. In "The Big Questions: Evolution," Francisco Ayala answers the 20 key questions: What is evolution? Was Darwin right? What is natural selection? What is survival of the fittest? Is evolution a random process? What is a species? What are chromosomes, genes and DNA? How do genes build bodies? What is molecular evolution? How did life begin? What is the tree of life? Am I really a monkey? What does the fossil record tell us? What is the missing link? Is intelligence inherited? Will humans continue to evolve? Can I clone myself? Where does morality come from? Is language a uniquely human attribute? Is Creationism true?

    Konrad Lorenz was gifted with a similar power of understanding the animal world. He was that rare beast, a brilliant scientist who could write (and indeed draw) beautifully. He did more than any other person to establish and popularize the study of how animals behave, receiving a Nobel Prize for his work. King Solomon's Ring, the book which brought him worldwide recognition, is a delightful treasury of observations and insights into the lives of all sorts of creatures, from jackdaws and water-shrews to dogs, cats and even wolves. Charmingly illustrated by Lorenz himself, this book is a wonderfully written introduction to the world of our furred and feathered friends, a world which often provides an uncanny resemblance to our own. A must for any animal-lover!

    William H. Cropper vividly portrays the life and accomplishments of such giants as Galileo and Isaac Newton, Marie Curie and Ernest Rutherford, Albert Einstein and NielsBohr, right up to contemporary figures such as Richard Feynman, Murray Gell-Mann, and Stephen Hawking. We meet scientists--all geniuses--who could be gregarious, aloof, unpretentious, friendly, dogged, imperious, generous to colleagues or contentious rivals. As Cropper captures their personalities, he also offers vivid portraits of their great moments of discovery, their bitter feuds, their relations with family and friends, their religious beliefs and education. In addition, Cropper has grouped these biographies by discipline--mechanics, thermodynamics, particle physics, and others--eachsection beginning with a historical overview. Thus in the section on quantum mechanics, readers can see how the work of Max Planck influenced Niels Bohr, and how Bohr in turn influenced Werner Heisenberg.Our understanding of the physical world has increased dramatically in the last four centuries. With Great Physicists, readers can retrace the footsteps of the men and women who led the way.

    But molecules, such as water and sugar, are not alive. So how do our cells--assemblies of otherwise "dead" molecules--come to life, and together constitute a living being? In "Life's Ratchet," physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale. The complex molecules of our cells can rightfully be called "molecular machines," or "nanobots"; these machines, unlike any other, work autonomously to create order out of chaos. Tiny electrical motors turn electrical voltage into motion, tiny factories custom-build other molecular machines, and mechanical machines twist, untwist, separate and package strands of DNA. The cell is like a city--an unfathomable, complex collection of molecular worker bees working together to create something greater than themselves. Life, Hoffman argues, emerges from the random motions of atoms filtered through the sophisticated structures of our evolved machinery. We are essentially giant assemblies of interacting nanoscale machines; machines more amazing than can be found in any science fiction novel. Incredibly, the molecular machines in our cells function without a mysterious "life force," nor do they violate any natural laws. Scientists can now prove that life is not supernatural, and that it can be fully understood in the context of science. Part history, part cutting-edge science, part philosophy, "Life's Ratchet" takes us from ancient Greece to the laboratories of modern nanotechnology to tell the story of our quest for the machinery of life.

    People knew the basics: men and women had sex, and sometimes babies followed. But beyond that the origins of life were a colossal mystery. The Seeds of Life is the remarkable and rollicking story of how a series of blundering geniuses and brilliant amateurs struggled for two centuries to discover where, exactly, babies come from. Taking a page from investigative thrillers, acclaimed science writer Edward Dolnick looks to these early scientists as if they were detectives hot on the trail of a bedeviling and urgent mystery. These strange searchers included an Italian surgeon using shark teeth to prove that female reproductive organs were not 'failed' male genitalia, and a Catholic priest who designed ingenious miniature pants to prove that frogs required semen to fertilize their eggs. A witty and rousing history of science, The Seeds of Life presents our greatest scientists struggling-against their perceptions, their religious beliefs, and their deep-seated prejudices-to uncover how and where we come from.
