    Its effects on our view of life have been wide and deep. One of the most world-shaking books ever published, Charles Darwin's On the Origin of Species, first appeared in print over 130 years ago, and it touched off a debate that rages to this day.Every modern evolutionist turns to Darwin's work again and again. Current controversies in the life sciences very often have as their starting point some vagueness in Darwin's writings or some question Darwin was unable to answer owing to the insufficient biological knowledge available during his time. Despite the intense study of Darwin's life and work, however, many of us cannot explain his theories (he had several separate ones) and the evidence and reasoning behind them, nor do we appreciate the modifications of the Darwinian paradigm that have kept it viable throughout the twentieth century.Who could elucidate the subtleties of Darwin's thought and that of his contemporaries and intellectual heirs--A. R. Wallace, T. H. Huxley, August Weismann, Asa Gray--better than Ernst Mayr, a man considered by many to be the greatest evolutionist of the century? In this gem of historical scholarship, Mayr has achieved a remarkable distillation of Charles Darwin's scientific thought and his enormous legacy to twentieth-century biology. Here we have an accessible account of the revolutionary ideas that Darwin thrust upon the world. Describing his treatise as "one long argument," Darwin definitively refuted the belief in the divine creation of each individual species, establishing in its place the concept that all of life descended from a common ancestor. He proposed the idea that humans were not the special products of creation but evolved according to principles that operate everywhere else in the living world; he upset current notions of a perfectly designed, benign natural world and substituted in their place the concept of a struggle for survival; and he introduced probability, chance, and uniqueness into scientific discourse.This is an important book for students, biologists, and general readers interested in the history of ideas--especially ideas that have radically altered our worldview. Here is a book by a grand master that spells out in simple terms the historical issues and presents the controversies in a manner that makes them understandable from a modern perspective.

    The first small cities formed not only the cradle of civilization, but the spawning ground for the earliest viral epidemics, the first opportunity for viruses to find a home in the human herd. This is a story of fear and ignorance, as everything from demons and the wrath of the gods to minority groups have been blamed for epidemics from smallpox to yellow fever to AIDS. It is a story of grief and heartbreak, as hundreds of thousands, sometimes millions, are wiped out in a single year. And it is a story of great bravery and sacrifice, as doctors and nurses put themselves in harm's way to combat yellow fever in Memphis and Ebola in Zaire, and as researchers risk their own lives to test theories of vaccines and the transmission of disease. Now, in Viruses, Plagues, and History, Michael B. A. Oldstone tells all these stories as he illuminates the history of the devastating diseases that have tormented humanity.Oldstone focuses his tale on a few of the most famous viruses humanity has battled, beginning with some we have effectively defeated, such as smallpox, polio, and measles. Nearly 300 million people were killed by smallpox in this century alone -- more than were killed in all the wars of the twentieth century combined. The author presents a vivid account of the long campaign against the virus, the insightful work of Edward Jenner, who created the smallpox vaccine from cowpox virus in 1796, and the monumental efforts of D. A. Henderson and an army of W.H.O. health care workers to finally eradicate smallpox. The smallpox virus remains the only organism that we have deliberately pushed to complete extinction in the wild.Oldstone then describes the fascinating viruses that have captured headlines in more recent years: Ebola and other hemorrhagic fevers, which literally turn their victims' organs to a bloody pulp; the Hantavirus outbreaks in the southwestern United States and elsewhere; mad cow disease, a frightening illness made worse by government mishandling and secrecy; and, of course, AIDS, often called the plague of our time. And he tells us of the many scientists watching and waiting even now for the next great plague, monitoring influenza strains to see whether the deadly variant from 1918 -- a viral strain that killed over 20 million people in 1918-1919, more than twice the military and civilian casualties of the First World War -- will make a comeback.Viruses have enormous power. They have wiped out cities, brought down dynasties, and helped destroy civilizations. But, as Michael Oldstone reveals, scientific research has given us the power to tame many of these viruses as well. Viruses, Plagues, and History shows us the panorama of humanity's long-standing conflict with our unseen viral enemies, from our successes to our continuing struggles. Oldstone's book is a vivid history of a fascinating field, and a highly reliable dispatch from a worker on the frontiers of this ongoing campaign.

    The Repository for Germinal Choice–nicknamed the Nobel Prize sperm bank–opened to notorious fanfare in 1980, and for two decades, women flocked to it from all over the country to choose a sperm donor from its roster of Nobel-laureate scientists, mathematical prodigies, successful businessmen, and star athletes. But the bank quietly closed its doors in 1999–its founder dead, its confidential records sealed, and the fate of its children and donors unknown. In early 2001, award-winning columnist David Plotz set out to solve the mystery of the Nobel Prize sperm bank.Plotz wrote an article for Slate inviting readers to contact him–confidentially–if they knew anything about the bank. The next morning, he received an email response, then another, and another–each person desperate to talk about something they had kept hidden for years. Now, in The Genius Factory, Plotz unfolds the full and astonishing story of the Nobel Prize sperm bank and its founder’s radical scheme to change our world.Believing America was facing genetic catastrophe, Robert Graham, an eccentric millionaire, decided he could reverse the decline by artificially inseminating women with the sperm of geniuses. In February 1980, Graham opened the Repository for Germinal Choice and stocked it with the seed of gifted scientists, inventors, and thinkers. Over the next nineteen years, Graham’s “genius factory” produced more than two hundred children.What happened to them? Were they the brilliant offspring that Graham expected? Did any of the “superman” fathers care about the unknown sons and daughters who bore their genes? What were the mothers like? Crisscrossing the country and logging countless hours online, Plotz succeeded in tracking down previously unknown family members–teenage half-brothers who ended up following vastly different paths, mothers who had wondered for years about the identities of the donors they had selected on the basis of code names and brief character profiles, fathers who were proud or ashamed or simply curious about the children who had been created from their sperm samples. The children of the “genius factory” are messengers from the future–a future that is bearing down on us fast. What will families be like when parents routinely “shop” for their kids’ genes? What will children be like when they’re programmed for greatness? In this stunning, eye-opening book, one of our finest young journalists previews America’s coming age of genetic expectations.From the Hardcover edition.

    But philosopher and cognitive scientist Andy Clark sees it differently. Cyborgs, he writes, are not something to be feared--we already are cyborgs. In Natural-Born Cyborgs, Clark argues that what makes humans so different from other species is our capacity to fully incorporate tools and supporting cultural practices into our existence. Technology as simple as writing on a sketchpad, as familiar as Google or a cellular phone, and as potentially revolutionary as mind-extending neural implants--all exploit our brains' astonishingly plastic nature. Our minds are primed to seek out and incorporate non-biological resources, so that we actually think and feel through our best technologies. Drawing on his expertise in cognitive science, Clark demonstrates that our sense of self and of physical presence can be expanded to a remarkable extent, placing the long-existing telephone and the emerging technology of telepresence on the same continuum. He explores ways in which we have adapted our lives to make use of technology (the measurement of time, for example, has wrought enormous changes in human existence), as well as ways in which increasingly fluid technologies can adapt to individual users during normal use. Bio-technological unions, Clark argues, are evolving with a speed never seen before in history. As we enter an age of wearable computers, sensory augmentation, wireless devices, intelligent environments, thought-controlled prosthetics, and rapid-fire information search and retrieval, the line between the user and her tools grows thinner day by day. This double whammy of plastic brains and increasingly responsive and well-fitted tools creates an unprecedented opportunity for ever-closer kinds of human-machine merger, he writes, arguing that such a merger is entirely natural. A stunning new look at the human brain and the human self, Natural Born Cyborgs reveals how our technology is indeed inseparable from who we are and how we think.

    Putting people into places and situations unprecedented in history is stirred the imagination while the human experience was expanding and redefining. Yet, space exploration compels humans to confront a hostile environment of cosmic radiations, radical changes in the gravity and magnetic fields, as well as social isolation. Therefore, any space traveller is submitted to relevant health-related threats. In the twenty-first century, human space flight is poised to continue, but it will enjoy the ongoing developments in science and technology. It will become more networked, more global, and more oriented toward primary goals. A novel international human space flight policy could help achieve these objectives by clarifying the rationale, the ethics of acceptable risk, the role of remote presence, and the need for balance between funding and ambition to justify the risk of human lives. In order to address such a challenge, a preliminary careful survey of the available scientific data is mandatory to set forth adequate countermeasures. Envisaged solutions should provide a sound and technically feasible approach for counteracting microgravity and cosmic rays effects, which represent the main health risk for space crews. This objective must necessarily be sustained by national/international space agencies, which would coordinate their common efforts into a defined international spaceflight program.

    But things didn't turn out that way. For a start, we turned out to have far fewer genes than originally thought - just over 20,000, the same sort of number as a fruit fly or worm. What's more, the proportionof DNA consisting of genes coding for proteins was a mere 2%. So, was the rest of the genome accumulated 'junk'?Things have changed since those early heady days of the Human Genome Project. But the emerging picture is if anything far more exciting. In this book, John Parrington explains the key features that are coming to light - some, such as the results of the international ENCODE programme, still much debated and controversial in their scope. He gives an outline of the deeper genome, involving layers of regulatory elements controlling and coordinating the switching on and off of genes; the impact ofits 3D geometry; the discovery of a variety of new RNAs playing critical roles; the epigenetic changes influenced by the environment and life experiences that can make identical twins different and be passed on to the next generation; and the clues coming out of comparisons with the genomes ofNeanderthals as well as that of chimps about the development our species. We are learning more about ourselves, and about the genetic aspects of many diseases. But in its complexity, flexibility, and ability to respond to environmental cues, the human genome is proving to be far more subtle than we ever imagined.

    In The Horse, the journalist and equestrienne Wendy Williams brings that story brilliantly to life.Williams chronicles the 56-million-year journey of horses as she visits with horse experts around the world, revealing what our biological affinities and differences can tell us about the bond between horses and humans, and what our noble companion may think and feel. Indeed, recent scientific breakthroughs regarding the social and cognitive capacities of the horse and its ability to adapt to changing ecosystems indicate that this animal is a major evolutionary triumph.Williams charts the course that leads to our modern Equus-from the protohorse to the Dutch warmbloods, thoroughbreds, and miniature horses of the twenty-first century. She observes magnificent ancient cave art that signals a deep respect and admiration for horses well before they were domesticated, visits the mountains of Wyoming with an expert in equine behavior to understand the dynamics of free-roaming mustangs, witnesses the fluid gracefulness of the famous Lipizzaners of Vienna, contemplates what life is like for the sure-footed, mustachioed Garrano horses who thrive on the rugged terrain of Galicia, celebrates the Takhi horses of Mongolia, and more. She blends profound scientific insights with remarkable stories to create a unique biography of the horse as a sentient being with a fascinating past and a finely nuanced mind.The Horse is a revelatory account of the animal who has been at our side through the ages, carrying us into battle and traveling with us across the plains. Enriched by Wendy Williams's own experience with horses, The Horse is a masterful work of narrative nonfiction that pays tribute to this champion of the natural world.

    The culprit--so necessary and yet the source of such upheaval--is the X chromosome, and this is its story. An enlightening and entertaining tour of the cultural and natural history of this intriguing member of the genome, "The X in Sex" traces the journey toward our current understanding of the nature of X. From its chance discovery in the nineteenth century to the promise and implications of ongoing research, David Bainbridge shows how the X evolved and where it and its counterpart Y are going, how it helps assign developing human babies their sex--and maybe even their sexuality--and how it affects our lives in infinitely complex and subtle ways. X offers cures for disease, challenges our cultural, ethical, and scientific assumptions about maleness and femaleness, and has even reshaped our views of human evolution and human nature.
