Why do living things and physical phenomena take the forms they do? Analyzing the mathematical and physical aspects of biological processes, this historic work, first published in 1917, has become renowned as well for the poetry of is descriptions.

    Richard Leakey's personal account of his fossil hunting and landmark discoveries at Lake Turkana, his reassessment of human prehistory based on new evidence and analytic techniques, and his profound pondering of how we became "human" and what being "human" really means.

    While an illness keeps her bedridden, Bailey watches a wild snail that has taken up residence on her nightstand. As a result, she discovers the solace and sense of wonder that this mysterious creature brings and comes to a greater understanding of her own confined place in the world. Intrigued by the snail’s molluscan anatomy, cryptic defenses, clear decision making, hydraulic locomotion, and mysterious courtship activities, Bailey becomes an astute and amused observer, providing a candid and engaging look into the curious life of this underappreciated small animal.  Told with wit and grace, The Sound of a Wild Snail Eating is a remarkable journey of survival and resilience, showing us how a small part of the natural world illuminates our own human existence and provides an appreciation of what it means to be fully alive.

    While most of these discoveries live quietly in museum collections, there are a few that have become world-renowned celebrity personas—ambassadors of science that speak to public audiences. In Seven Skeletons, historian of science Lydia Pyne explores how seven such famous fossils of our ancestors have the social cachet they enjoy today.Drawing from archives, museums, and interviews, Pyne builds a cultural history for each celebrity fossil—from its discovery to its afterlife in museum exhibits to its legacy in popular culture. These seven include the three-foot tall “hobbit” from Flores, the Neanderthal of La Chapelle, the Taung Child, the Piltdown Man hoax, Peking Man, Australopithecus sediba, and Lucy—each embraced and celebrated by generations, and vivid examples of how discoveries of how our ancestors have been received, remembered, and immortalized. With wit and insight, Pyne brings to life each fossil, and how it is described, put on display, and shared among scientific communities and the broader public. This fascinating, endlessly entertaining book puts the impact of paleoanthropology into new context, a reminder of how our past as a species continues to affect, in astounding ways, our present culture and imagination.

    In the book, Sagan explores 15 billion years of cosmic evolution and the development of science and civilization. Cosmos traces the origins of knowledge and the scientific method, mixing science and philosophy, and speculates to the future of science. The book also discusses the underlying premises of science by providing biographical anecdotes about many prominent scientists throughout history, placing their contributions into the broader context of the development of modern science.The book covers a broad range of topics, comprising Sagan's reflections on anthropological, cosmological, biological, historical, and astronomical matters from antiquity to contemporary times. Sagan reiterates his position on extraterrestrial life—that the magnitude of the universe permits the existence of thousands of alien civilizations, but no credible evidence exists to demonstrate that such life has ever visited earth.

    In addition to offering a clear-eyed explanation of the root causes of this insidious and entrenched bias and laying out its effects, she suggests concrete steps we can take to cure it.

    Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    They evolved from land-roaming, dog-like creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Whales fill us with terror, awe, and affection--yet we know hardly anything about them, and they only enter our awareness when they die, struck by a ship or stranded in the surf. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea? Why do they beach themselves? What do their lives tell us about our oceans, and evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive?Nick Pyenson's research has given us the answers to some of our biggest questions about whales. Nick's rich storytelling takes us to the cool halls deep inside the Smithsonian's priceless fossil collection, to the frigid fishing decks on Antarctic whaling stations, and to the blazing hot desert of Chile where scientists race against time to document the largest fossil whalebone site on earth. Spying on Whales is science writing at its best: an author who is an incredible, passionate writer, at the forefront of his field, on a topic that invokes deep fascination.

    According to this false-yet-familiar story, the divisions between men and women are in nature alone and not part of culture. Drawing on evolutionary science, psychology, neuroscience, endocrinology, and philosophy, Testosterone Rex disproves this ingrained myth and calls for a more equal society based on both sexes’ full human potential.

    With more than one in every five people over the age of fourteen addicted, drug abuse has been called the most formidable health problem worldwide. If we are not victims ourselves, we all know someone struggling with the merciless compulsion to alter their experience by changing how their brain functions.Drawing on years of research--as well as personal experience as a recovered addict--researcher and professor Judy Grisel has reached a fundamental conclusion: for the addict, there will never be enough drugs. The brain's capacity to learn and adapt is seemingly infinite, allowing it to counteract any regular disruption, including that caused by drugs. What begins as a normal state punctuated by periods of being high transforms over time into a state of desperate craving that is only temporarily subdued by a fix, explaining why addicts are unable to live either with or without their drug. One by one, Grisel shows how different drugs act on the brain, the kind of experiential effects they generate, and the specific reasons why each is so hard to kick.Grisel's insights lead to a better understanding of the brain's critical contributions to addictive behavior, and will help inform a more rational, coherent, and compassionate response to the epidemic in our homes and communities.

    Every new reader's brain possesses the extraordinary capacity to rearrange itself beyond its original abilities in order to understand written symbols. But how does the brain learn to read? As world-renowned cognitive neuroscientist and scholar of reading Maryanne Wolf explains in this impassioned book, we taught our brain to read only a few thousand years ago, and in the process changed the intellectual evolution of our species.Wolf tells us that the brain that examined tiny clay tablets in the cuneiform script of the Sumerians is configured differently from the brain that reads alphabets or of one literate in today's technology.There are critical implications to such an evolving brain. Just as writing reduced the need for memory, the proliferation of information and the particular requirements of digital culture may short-circuit some of written language's unique contributions—with potentially profound consequences for our future.Turning her attention to the development of the individual reading brain, Wolf draws on her expertise in dyslexia to investigate what happens when the brain finds it difficult to read. Interweaving her vast knowledge of neuroscience, psychology, literature, and linguistics, Wolf takes the reader from the brains of a pre-literate Homer to a literacy-ambivalent Plato, from an infant listening to Goodnight Moon to an expert reader of Proust, and finally to an often misunderstood child with dyslexia whose gifts may be as real as the challenges he or she faces.As we come to appreciate how the evolution and development of reading have changed the very arrangement of our brain and our intellectual life, we begin to realize with ever greater comprehension that we truly are what we read. Ambitious, provocative, and rich with examples, Proust and the Squid celebrates reading, one of the single most remarkable inventions in history. Once embarked on this magnificent story of the reading brain, you will never again take for granted your ability to absorb the written word.

    It enabled us to migrate out of Africa and to spread as far as Alaska and Australia. Every day, we put one foot in front of the other―yet how many of us know how we do that, or appreciate the advantages it gives us?Neuroscientist Shane O’Mara invites us to marvel at the benefits walking confers on our bodies and brains. From walking’s evolutionary origins, traced back millions of years to life forms on the ocean floor, to new findings from cutting- edge research, he reveals how the brain and nervous system give us the ability to balance, weave through a crowded city, and run our “inner GPS” system. Walking, in turn, spurs our imaginations and boosts our moods. In Praise of Walking illuminates the joys, health benefits, and mechanics of walking―and reminds us to get out of our chairs and discover a happier, healthier, more creative self.

    As a member of the Citizen Potawatomi Nation, she embraces the notion that plants and animals are our oldest teachers. In Braiding Sweetgrass, Kimmerer brings these lenses of knowledge together to show that the awakening of a wider ecological consciousness requires the acknowledgment and celebration of our reciprocal relationship with the rest of the living world. For only when we can hear the languages of other beings are we capable of understanding the generosity of the earth, and learning to give our own gifts in return.

    Yet this is the first book to tell the story of rain. Cynthia Barnett's  Rain begins four billion years ago with the torrents that filled the oceans, and builds to the storms of climate change. It weaves together science—the true shape of a raindrop, the mysteries of frog and fish rains—with the human story of our ambition to control rain, from ancient rain dances to the 2,203 miles of levees that attempt to straitjacket the Mississippi River. It offers a glimpse of our "founding forecaster," Thomas Jefferson, who measured every drizzle long before modern meteorology. Two centuries later, rainy skies would help inspire Morrissey’s mopes and Kurt Cobain’s grunge. Rain is also a travelogue, taking readers to Scotland to tell the surprising story of the mackintosh raincoat, and to India, where villagers extract the scent of rain from the monsoon-drenched earth and turn it into perfume. Now, after thousands of years spent praying for rain or worshiping it; burning witches at the stake to stop rain or sacrificing small children to bring it; mocking rain with irrigated agriculture and cities built in floodplains; even trying to blast rain out of the sky with mortars meant for war, humanity has finally managed to change the rain. Only not in ways we intended. As climate change upends rainfall patterns and unleashes increasingly severe storms and drought, Barnett shows rain to be a unifying force in a fractured world. Too much and not nearly enough, rain is a conversation we share, and this is a book for everyone who has ever experienced it.

    But in the modern world, the breast is changing. Breasts are getting bigger, arriving earlier, and attracting newfangled chemicals. Increasingly, the odds are stacked against us in the struggle with breast cancer, even among men. What makes breasts so mercurial—and so vulnerable?In this informative and highly entertaining account, intrepid science reporter Florence Williams sets out to uncover the latest scientific findings from the fields of anthropology, biology, and medicine. Her investigation follows the life cycle of the breast from puberty to pregnancy to menopause, taking her from a plastic surgeon’s office where she learns about the importance of cup size in Texas to the laboratory where she discovers the presence of environmental toxins in her own breast milk. The result is a fascinating exploration of where breasts came from, where they have ended up, and what we can do to save them.
