In fact the currently accepted history of life on Earth is flawed and out of date.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.

    This chance encounter in the basement of the Natural History Museum of Los Angeles County sparked Troll’s obsession with Helicoprion, a mysterious monster from deep time.In 2010, tattooed undergraduate student and returning Iraq War veteran Jesse Pruitt became seriously smitten with a Helicoprion fossil in a museum basement in Idaho. These two bizarre-shark disciples found each other, and an unconventional band of collaborators grew serendipitously around them, determined to solve the puzzle of the mysterious tooth whorl once and for all.Helicoprion was a Paleozoic chondrichthyan about the size of a modern great white shark, with a circular saw of teeth centered in its lower jaw—a feature unseen in the shark world before or since. For some ten million years, long before the Age of Dinosaurs, Helicoprion patrolled the shallow seas around the supercontinent Pangaea as the apex predator of its time.Just a few tumultuous years after Pruitt and Troll met, imagination, passion, scientific process, and state-of-the-art technology merged into an unstoppable force that reanimated the remarkable creature—and made important new discoveries.In this groundbreaking book, Susan Ewing reveals these revolutionary insights into what Helicoprion looked like and how the tooth whorl functioned—pushing this dazzling and awe-inspiring beast into the spotlight of modern science.

    In the early 1800s, women were dying in large numbers from treatable diseases because they avoided receiving medical care. Examinations performed by male doctors were often demeaning and even painful. In addition, women faced stigma from illness—a diagnosis could greatly limit their ability to find husbands, jobs or be received in polite society.Motivated by personal loss and frustration over inadequate medical care, Elizabeth Blackwell, Elizabeth Garrett Anderson and Sophia Jex-Blake fought for a woman’s place in the male-dominated medical field. For the first time ever, Women in White Coats tells the complete history of these three pioneering women who, despite countless obstacles, earned medical degrees and paved the way for other women to do the same. Though very different in personality and circumstance, together these women built women-run hospitals and teaching colleges—creating for the first time medical care for women by women.With gripping storytelling based on extensive research and access to archival documents, Women in White Coats tells the courageous history these women made by becoming doctors, detailing the boundaries they broke of gender and science to reshape how we receive medical care today.

    This book shows how easy it is to fill our gardens with everything from foxes, frogs and mice, to butterflies, ladybirds and thousands of fascinating creepy-crawlies.

    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!
