"Lianyungang, a booming port city, has China's most extreme gender ratio for children under four: 163 boys for every 100 girls. These numbers don't seem terribly grim, but in ten years, the skewed sex ratio will pose a colossal challenge. By the time those children reach adulthood, their generation will have twenty-four million more men than women. The prognosis for China's neighbors is no less bleak: Asia now has 163 million females "missing" from its population. Gender imbalance reaches far beyond Asia, affecting Georgia, Eastern Europe, and cities in the U.S. where there are significant immigrant populations. The world, therefore, is becoming increasingly male, and this mismatch is likely to create profound social upheaval. Historically, eras in which there have been an excess of men have produced periods of violent conflict and instability. Mara Hvistendahl has written a stunning, impeccably-researched book that does not flinch from examining not only the consequences of the misbegotten policies of sex selection but Western complicity with them"--

A lavishly illustrated look at how evolution plays out in selective breeding Unnatural Selection is a stunningly illustrated book about selective breeding--the ongoing transformation of animals at the hand of man. More important, it's a book about selective breeding on a far, far grander scale—a scale that encompasses all life on Earth. We'd call it evolution. A unique fusion of art, science, and history, this book celebrates the 150th anniversary of Charles Darwin's monumental work The Variation of Animals and Plants under Domestication, and is intended as a tribute to what Darwin might have achieved had he possessed that elusive missing piece to the evolutionary puzzle—the knowledge of how individual traits are passed from one generation to the next. With the benefit of a century and a half of hindsight, Katrina van Grouw explains evolution by building on the analogy that Darwin himself used—comparing the selective breeding process with natural selection in the wild, and, like Darwin, featuring a multitude of fascinating examples. This is more than just a book about pets and livestock, however. The revelation of Unnatural Selection is that identical traits can occur in all animals, wild and domesticated, and both are governed by the same evolutionary principles. As van Grouw shows, animals are plastic things, constantly changing. In wild animals the changes are usually too slow to see—species appear to stay the same. When it comes to domesticated animals, however, change happens fast, making them the perfect model of evolution in action. Suitable for the lay reader and student, as well as the more seasoned biologist, and featuring more than four hundred breathtaking illustrations of living animals, skeletons, and historical specimens, Unnatural Selection will be enjoyed by anyone with an interest in natural history and the history of evolutionary thinking.

Gonorrhea. Bed bugs. Weeds. Salamanders. People. All are evolving, some surprisingly rapidly, in response to our chemical age. In Unnatural Selection, Emily Monosson shows how our drugs, pesticides, and pollution are exerting intense selection pressure on all manner of species. And we humans might not like the result. Monosson reveals that the very code of life is more fluid than once imagined. When our powerful chemicals put the pressure on to evolve or die, beneficial traits can sweep rapidly through a population. Species with explosive population growth--the bugs, bacteria, and weeds--tend to thrive, while bigger, slower-to-reproduce creatures, like ourselves, are more likely to succumb. Unnatural Selection is eye-opening and more than a little disquieting. But it also suggests how we might lessen our impact: manage pests without creating super bugs; protect individuals from disease without inviting epidemics; and benefit from technology without threatening the health of our children.

Adopted at birth, Andrea Ross grew up inhabiting two ecosystems: one was her tangible, adoptive family, the other her birth family, whose mysterious landscape was hidden from her. In this coming-of-age memoir, Ross narrates how in her early twenties, while working as a ranger in Grand Canyon National Park, she embarked on a journey to discover where she came from and, ultimately, who she was. After many missteps and dead ends, Ross uncovered her heartbreaking and inspiring origin story and began navigating the complicated turns of reuniting with her birth parents and their new families. Through backcountry travel in the American West, she also came to understand her place in the world, realizing that her true identity lay not in a choice between adopted or biological parents, but in an expansion of the concept of family.

Timely and provocative, Unnatural Selection explores advances in human genetic research--and how these advances are redefining the way we view ourselves and our world. From physical illnesses to behavioral traits, the mapping of our genes is moving with astonishing rapidity. Every week brings word of new genetic findings. Soon we will have extraordinary amounts of information about our most intimate selves. But--as this insightful, sometimes disturbing book makes clear--this knowledge raises serious ethical, legal, and personal issues none of us can afford to ignore. With each new genetic test, new questions arise. Just because the test exists, should we be tested? The tests are often marketed by for-profit companies. Who determines what conditions warrant testing? If a person discovers he or she carries the gene for a particular disorder, what then? How private is this knowledge of our most intimate selves? Who has access to it in an age of medical claim forms and computer networks? In clear and accessible language, Unnatural Selection takes us into the world of researchers, physicians, ethicists, families, and people like ourselves as they contemplate the promise and the pitfalls of this exploding field of knowledge.

Challenging conventional constructions of the Harlem Renaissance and American modernism, Daylanne English links writers from both movements to debates about eugenics in the Progressive Era. She argues that, in the 1920s, the form and content of writings by figures as disparate as W. E. B. Du Bois, T. S. Eliot, Gertrude Stein, and Nella Larsen were shaped by anxieties regarding immigration, migration, and intraracial breeding. English's interdisciplinary approach brings together the work of those canonical writers with relatively neglected literary, social scientific, and visual texts. She examines antilynching plays by Angelina Weld Grimke as well as the provocative writings of white female eugenics field workers. English also analyzes the Crisis magazine as a family album filtering uplift through eugenics by means of photographic documentation of an ever-improving black race. English suggests that current scholarship often misreads early-twentieth-century visual, literary, and political culture by applying contemporary social and moral standards to the past. Du Bois, she argues, was actually more of a eugenicist than Eliot. Through such reconfiguration of the modern period, English creates an allegory for the American present: because eugenics was, in its time, widely accepted as a reasonable, progressive ideology, we need to consider the long-term implications of contemporary genetic engineering, fertility enhancement and control, and legislation promoting or discouraging family growth.

An eye-opening, mind-bending exploration of how mankind is reshaping its genetic future, based on the viral TED Talk series “Will Our Kids Be a Different Species?” and “The Next Species of Human.” Are you willing to engineer the DNA of your unborn children and grand-children to be healthier? Better looking? More intelligent? Why are rates of autism, asthma, and allergies exploding at an unprecedented pace? Why are humans living longer and having far fewer kids? Futurist Juan Enriquez and scientist Steve Gullans conduct a sweeping tour of how humans are changing the course of evolution for all species—sometimes intentionally, sometimes not. For example: • What if life forms are limited only by the bounds of our imagination? Are designer babies and pets, de-extinction, even entirely newspecies fair game? • As humans, animals, and plants become ever more resistant to disease and aging, what will become the leading causes of death? • Man-machine interfaces may allow humans to live much longer. What will happen when we transfer parts of our “selves” into clones, into stored cells and machines? Though these harbingers of change are deeply unsettling, the authors argue we are also in an epoch of tremendous opportunity. Future humans, perhaps a more diverse, resilient, gentler, and intelligent species, may become better caretakers of the planet—but only if we make the right choices now. Intelligent, provocative, and optimistic, Evolving Ourselves is the ultimate guide to the next phase of life on Earth. Chosen by Nature magazine as a Fall 2016 season highlight.
