While some books explore our genetic inheritance and popular television shows celebrate ancestry, this is the first book to explore how everything from DNA to emotions to names and the stories that form our lives are all part of our human legacy. This book shows how trust is inherited in Africa, silence is passed down in Tasmania, and how the history of nations is written in our DNA. From fateful, ancient encounters to modern mass migrations and medical diagnoses, Kenneally explains how the forces that shaped the history of the world ultimately shape each human who inhabits it. The Invisible History of the Human Race is a deeply researched, carefully crafted, and provocative perspective on how our stories, psychology, and genetics affect our past and our future.

    Mainstream science--as well as religious and cultural institutions--has maintained that men and women evolved in families in which a man's possessions and protection were exchanged for a woman's fertility and fidelity. But this narrative is collapsing. Fewer and fewer couples are getting married, and divorce rates keep climbing as adultery and flagging libido drag down even seemingly solid marriages.How can reality be reconciled with the accepted narrative? It can't be, according to renegade thinkers Christopher Ryan and Cacilda Jethá. While debunking almost everything we "know" about sex, they offer a bold alternative explanation in this provocative and brilliant book.Ryan and Jethá's central contention is that human beings evolved in egalitarian groups that shared food, child care, and, often, sexual partners. Weaving together convergent, frequently overlooked evidence from anthropology, archaeology, primatology, anatomy, and psychosexuality, the authors show how far from human nature monogamy really is. Human beings everywhere and in every era have confronted the same familiar, intimate situations in surprisingly different ways. The authors expose the ancient roots of human sexuality while pointing toward a more optimistic future illuminated by our innate capacities for love, cooperation, and generosity.With intelligence, humor, and wonder, Ryan and Jethá show how our promiscuous past haunts our struggles over monogamy, sexual orientation, and family dynamics. They explore why long-term fidelity can be so difficult for so many; why sexual passion tends to fade even as love deepens; why many middle-aged men risk everything for transient affairs with younger women; why homosexuality persists in the face of standard evolutionary logic; and what the human body reveals about the prehistoric origins of modern sexuality.In the tradition of the best historical and scientific writing, Sex at Dawn unapologetically upends unwarranted assumptions and unfounded conclusions while offering a revolutionary understanding of why we live and love as we do.

    Morell probes the moral and ethical dilemmas of recognizing that even “lesser animals” have cognitive abilities such as memory, feelings, personality, and self-awareness--traits that many in the twentieth century felt were unique to human beings.By standing behaviorism on its head, Morell brings the world of nature brilliantly alive in a nuanced, deeply felt appreciation of the human-animal bond, and she shares her admiration for the men and women who have simultaneously chipped away at what we think makes us distinctive while offering a glimpse of where our own abilities come from.

    For the seventeenth-century aristocratic Frenchman, it meant changing his shirt once a day, using perfume to obliterate both his own aroma and everyone else’s, but never immersing himself in – horrors! – water. By the early 1900s, an extraordinary idea took hold in North America – that frequent bathing, perhaps even a daily bath, was advisable. Not since the Roman Empire had people been so clean, and standards became even more extreme as the millennium approached. Now we live in a deodorized world where germophobes shake hands with their elbows and where sales of hand sanitizers, wipes and sprays are skyrocketing.The apparently routine task of taking up soap and water (or not) is Katherine Ashenburg’s starting point for a unique exploration of Western culture, which yields surprising insights into our notions of privacy, health, individuality, religion and sexuality.Ashenburg searches for clean and dirty in plague-ridden streets, medieval steam baths, castles and tenements, and in bathrooms of every description. She reveals the bizarre rescriptions of history’s doctors as well as the hygienic peccadilloes of kings, mistresses, monks and ordinary citizens, and guides us through the twists and turns to our own understanding of clean, which is no more rational than the rest. Filled with amusing anecdotes and quotations from the great bathers of history, The Dirt on Clean takes us on a journey that is by turns intriguing, humorous, startling and not always for the squeamish. Ashenburg’s tour of history’s baths and bathrooms reveals much about our changing and most intimate selves – what we desire, what we ignore, what we fear, and a significant part of who we are.

    Poisons permeate our world. They are in the environment, the workplace, the home. They are in food, our favorite whiskey, medicine, well water. They have been used to cure disease as well as to incapacitate and kill. They smooth wrinkles, block pain, stimulate, and enhance athletic ability. In this entertaining and fact-filled book, science writer Peter Macinnis considers poisons in all their aspects. He recounts stories of the celebrated poisoners in history and literature, from Nero to Thomas Wainewright, and from the death of Socrates to Hamlet and Peter Pan. He discusses the sources of various poisons-from cyanide to strychnine, from Botox to ricin and Sarin gas-as well as their detection. Then he analyzes the science of their action in the body and their uses in medicine, cosmetics, war, and terrorism. With wit and precision, he weighs such questions as: Was Lincoln's volatility caused by mercury poisoning? Was Jack the Ripper an arsenic eater? Can wallpaper kill? For anyone who has ever wondered and been afraid to ask, here is a rich miscellany for your secret questions about toxins.

    In captivity, octopuses have been known to identify individual human keepers, raid neighboring tanks for food, turn off lightbulbs by spouting jets of water, plug drains, and make daring escapes. How is it that a creature with such gifts evolved through an evolutionary lineage so radically distant from our own? What does it mean that evolution built minds not once but at least twice? The octopus is the closest we will come to meeting an intelligent alien. What can we learn from the encounter?In Other Minds, Peter Godfrey-Smith, a distinguished philosopher of science and a skilled scuba diver, tells a bold new story of how subjective experience crept into being—how nature became aware of itself. As Godfrey-Smith stresses, it is a story that largely occurs in the ocean, where animals first appeared. Tracking the mind’s fitful development, Godfrey-Smith shows how unruly clumps of seaborne cells began living together and became capable of sensing, acting, and signaling. As these primitive organisms became more entangled with others, they grew more complicated. The first nervous systems evolved, probably in ancient relatives of jellyfish; later on, the cephalopods, which began as inconspicuous mollusks, abandoned their shells and rose above the ocean floor, searching for prey and acquiring the greater intelligence needed to do so. Taking an independent route, mammals and birds later began their own evolutionary journeys.But what kind of intelligence do cephalopods possess? Drawing on the latest scientific research and his own scuba-diving adventures, Godfrey-Smith probes the many mysteries that surround the lineage. How did the octopus, a solitary creature with little social life, become so smart? What is it like to have eight tentacles that are so packed with neurons that they virtually “think for themselves”? What happens when some octopuses abandon their hermit-like ways and congregate, as they do in a unique location off the coast of Australia?By tracing the question of inner life back to its roots and comparing human beings with our most remarkable animal relatives, Godfrey-Smith casts crucial new light on the octopus mind—and on our own.

    The book documents the adverse environmental effects caused by the indiscriminate use of pesticides. Carson accused the chemical industry of spreading disinformation, and public officials of accepting the industry's marketing claims unquestioningly.The book appeared in September 1962 and the outcry that followed its publication forced the banning of DDT and spurred revolutionary changes in the laws affecting our air, land, and water. Carson’s book was instrumental in launching the environmental movement.

    Exploring the history of cannibalism, the neurology of people who are sexually attracted to animals, the evolution of human body fluids, the science of homosexuality, and serious questions about life and death, Bering astutely covers a generous expanse of our kaleidoscope of quirks and origins.With his characteristic irreverence and trademark cheekiness, Bering leaves no topic unturned or curiosity unexamined, and he does it all with an audaciously original voice. Whether you're interested in the psychological history behind the many facets of sexual desire or the evolutionary patterns that have dictated our current mystique and phallic physique, Why Is the Penis Shaped Like That? is bound to create lively discussion and debate for years to come.

    But our bins are just the starting point for a strange, impressive, mysterious, and costly journey that may also represent the greatest untapped opportunity of the century. In Garbology, Edward Humes investigates trash—what’s in it; how much we pay for it; how we manage to create so much of it; and how some families, communities, and even nations are finding a way back from waste to discover a new kind of prosperity. Along the way , he introduces a collection of garbage denizens unlike anyone you’ve ever met: the trash-tracking detectives of MIT, the bulldozer-driving sanitation workers building Los Angeles’ Garbage Mountain landfill, the artists residing in San Francisco’s dump, and the family whose annual trash output fills not a dumpster or a trash can, but a single mason jar.  Garbology reveals not just what we throw away, but who we are and where our society is headed. Waste is the one environmental and economic harm that ordinary working Americans have the power to change—and prosper in the process.

    Pigeons have been worshipped as fertility goddesses and used as crucial communicators in war by every major historical superpower from ancient Egypt to the United States, saving thousands of lives. Yet, without just cause, they are reviled today as “rats of the sky.” How did we come to misunderstand one of mankind’s most helpful and steadfast companions? Author Andrew D. Blechman traveled across the United States and Europe to meet with pigeon fanciers and pigeon haters in a quest to chronicle the pigeon’s transformation from beloved friend to feathered outlaw. Pigeons captures a Brooklyn man’s quest to win the Main Event (the pigeon world’s equivalent of the Kentucky Derby), as well as a pigeon shoot where entrants pay $150 to shoot live pigeons. Blechman tracks down Mike Tyson, the nation’s most famous pigeon lover, and he sheds light on a radical “pro-pigeon underground” in New York City. In Pigeons , Blechman tells for the first time the remarkable story behind this seemingly unremarkable bird.

    One-tenth of that amount will lower IQ.Nearly two out of every five African-American homes in Baltimore are plagued by lead-based paint. Almost all of the 37,500 Baltimore children who suffered lead poisoning from 2003 to 2015 were African-American.From injuries caused by lead poisoning to the devastating effects of atmospheric pollution, infectious disease, and industrial waste, Americans of color are harmed by environmental hazards in staggeringly disproportionate numbers. This systemic onslaught of toxic exposure and institutional negligence causes irreparable physical harm to millions of people across the country--cutting lives tragically short and needlessly burdening the health care system. But these deadly environments create another insidious and often overlooked consequence: robbing communities of color, and America as a whole, of intellectual power.The 1994 publication of The Bell Curve and its controversial thesis, catapulted the topic of genetic racial differences in IQ to the forefront of a renewed and heated debate. Now, in A Terrible Thing to Waste, award-winning science writer Harriet A. Washington adds her incisive analysis to the fray, arguing that IQ is a biased and flawed metric, but that it is useful for tracking cognitive damage. She tears apart the spurious notion of intelligence as an inherited trait, using copious data that instead point to a different cause of the reported African American-white IQ gap: environmental racism--a confluence of racism and other institutional factors that relegate marginalized communities to living and working near sites of toxic waste, pollution, and insufficient sanitation services. She investigates heavy metals, neuro-toxins, deficient prenatal care, bad nutrition, and even pathogens as chief agents influencing intelligence to explain why communities of color are disproportionately affected--and what can be done to remedy this devastating problem.Featuring extensive scientific research and Washington's sharp, lively reporting, A Terrible Thing to Waste is sure to outrage, transform the conversation, and inspire debate.

    Over time, seahorses have surfaced in some unlikely places. We see them immortalized in the decorative arts; in tribal folklore, literature, and ancient myth; and even on the pages of the earliest medical texts, prescribed to treat everything from skin complaints to baldness to flagging libido. Marine biologist Helen Scales eloquently shows that seahorses are indeed fish, though scientists have long puzzled over their exotic anatomy, and their very strange sex lives?male seahorses are the only males in the animal world that experience childbirth! Our first seahorse imaginings appeared six thousand years ago on cave walls in Australia. The ancient Greeks called the seahorse hippocampus (half-horse, half-fish) and sent it galloping through the oceans of mythology, pulling the sea god Poseidon?s golden chariot. The seahorse has even been the center of a modern-day international art scandal: A two-thousand-year-old winged seahorse brooch was plundered by Turkish tomb raiders and sold to the Metropolitan Museum of Art in New York. A book that is as charming as the seahorse itself, Poseidon?s Steed brings to life an aquatic treasure.Seahorses lead quiet lives, tucked away out of sight on the seafloor. It is rare to catch a glimpse of a seahorse in its natural habitat. But even if few have seen one live, these exotic, seemingly prehistoric creatures exist quite vividly in our imaginations and they have mesmerized scientists, artists, and storytellers throughout time with their otherworldly rarity. Poseidon?s Steed is a sweeping journey that takes us from the coral reefs and seagrass meadows of Indonesia where many seahorses makes their natural habitat to the back streets of Hong Kong where a thriving black market seahorse trade is concealed. Throughout history, seahorses have surfaced in some unexpected places and Scales also follows the seahorse back in time, from our most rudimentary seahorse imaginings six thousand years ago on cave walls in Australia, to the myths of ancient Greece. Scientists have long puzzled over seahorses? unusual anatomy and their very strange sex lives. And male seahorses are the only males in the animal world that experience childbirth! Seahorses are not what scientists call a ?keystone? species. They rely on a healthy ocean to survive, but the marine ecosystem does not rely on them. But their delicate beauty reminds us that we rely on the seas not only to fill our dinner plates, but also to feed our imaginations.

    Why does music evoke such powerful moods? The answers are at last be- coming clear, thanks to revolutionary neuroscience and the emerging field of evolutionary psychology. Both a cutting-edge study and a tribute to the beauty of music itself, This Is Your Brain on Music unravels a host of mysteries that affect everything from pop culture to our understanding of human nature, including: • Are our musical preferences shaped in utero? • Is there a cutoff point for acquiring new tastes in music? • What do PET scans and MRIs reveal about the brain’s response to music? • Is musical pleasure different from other kinds of pleasure?This Is Your Brain on Music explores cultures in which singing is considered an essential human function, patients who have a rare disorder that prevents them from making sense of music, and scientists studying why two people may not have the same definition of pitch. At every turn, this provocative work unlocks deep secrets about how nature and nurture forge a uniquely human obsession.

    Known as Monsanto’s Roundup by consumers, and as glyphosate by scientists, the world’s most popular weed killer is used everywhere from backyard gardens to golf courses to millions of acres of farmland. For decades it’s been touted as safe enough to drink, but a growing body of evidence indicates just the opposite, with research tying the chemical to cancers and a host of other health threats. In Whitewash, veteran journalist Carey Gillam uncovers one of the most controversial stories in the history of food and agriculture, exposing new evidence of corporate influence. Gillam introduces readers to farm families devastated by cancers which they believe are caused by the chemical, and to scientists whose reputations have been smeared for publishing research that contradicted business interests. Readers learn about the arm-twisting of regulators who signed off on the chemical, echoing company assurances of safety even as they permitted higher residues of the herbicide in food and skipped compliance tests. And, in startling detail, Gillam reveals secret industry communications that pull back the curtain on corporate efforts to manipulate public perception. Whitewash is more than an exposé about the hazards of one chemical or even the influence of one company. It’s a story of power, politics, and the deadly consequences of putting corporate interests ahead of public safety.
