But in recent decades, these claims have eroded, or even been disproven outright, by a revolution in the study of animal cognition. Take the way octopuses use coconut shells as tools; elephants that classify humans by age, gender, and language; or Ayumu, the young male chimpanzee at Kyoto University whose flash memory puts that of humans to shame. Based on research involving crows, dolphins, parrots, sheep, wasps, bats, whales, and of course chimpanzees and bonobos, Frans de Waal explores both the scope and the depth of animal intelligence. He offers a firsthand account of how science has stood traditional behaviorism on its head by revealing how smart animals really are, and how we’ve underestimated their abilities for too long.People often assume a cognitive ladder, from lower to higher forms, with our own intelligence at the top. But what if it is more like a bush, with cognition taking different forms that are often incomparable to ours? Would you presume yourself dumber than a squirrel because you’re less adept at recalling the locations of hundreds of buried acorns? Or would you judge your perception of your surroundings as more sophisticated than that of a echolocating bat? De Waal reviews the rise and fall of the mechanistic view of animals and opens our minds to the idea that animal minds are far more intricate and complex than we have assumed. De Waal’s landmark work will convince you to rethink everything you thought you knew about animal—and human—intelligence.

    People knew the basics: men and women had sex, and sometimes babies followed. But beyond that the origins of life were a colossal mystery. The Seeds of Life is the remarkable and rollicking story of how a series of blundering geniuses and brilliant amateurs struggled for two centuries to discover where, exactly, babies come from. Taking a page from investigative thrillers, acclaimed science writer Edward Dolnick looks to these early scientists as if they were detectives hot on the trail of a bedeviling and urgent mystery. These strange searchers included an Italian surgeon using shark teeth to prove that female reproductive organs were not 'failed' male genitalia, and a Catholic priest who designed ingenious miniature pants to prove that frogs required semen to fertilize their eggs. A witty and rousing history of science, The Seeds of Life presents our greatest scientists struggling-against their perceptions, their religious beliefs, and their deep-seated prejudices-to uncover how and where we come from.

    There are countless books on bird behavior, but Heinrich argues that some of the most amazing bird behaviors fall below the radar of what most birds do in aggregate. Heinrich’s “passionate observations [that] superbly mix memoir and science” (New York Times Book Review) lead to fascinating questions — and sometimes startling discoveries. A great crested flycatcher, while bringing food to the young in their nest, is attacked by the other flycatcher nearby. Why? A pair of Northern flickers hammering their nest-hole into the side of Heinrich’s cabin deliver the opportunity to observe the feeding competition between siblings, and to make a related discovery about nest-cleaning. One of a clutch of redstart warbler babies fledges out of the nest from twenty feet above the ground, and lands on the grass below. It can’t fly. What will happen next? Heinrich “looks closely, with his trademark ‘hands-and-knees science’ at its most engaging, [delivering] what can only be called psychological marvels of knowing” (Boston Globe). An eminent biologist shares the joys of bird-watching and how observing the anomalous behaviors of individual birds has guided his research.   Heinrich (Emeritus, Biology/Univ. of Vermont; The Homing Instinct: Meaning and Mystery in Animal Migration, 2014, etc.) smoothly describes how studying the daily lives of birds in their natural environments allows him to experience their world vicariously. Now retired and living in a cabin in the Maine woods, he devotes himself to closely observing “his avian neighbors, visitors, and vagrants, and keep[ing] daily records throughout spring, summer, fall, and winter.” Every year, he welcomes a pair of broad-wing hawks who feast at a vernal pond populated by frogs, spring peepers, and salamanders while refurbishing their old nest. Unusually, they provide a fern cover on the nest, which they update on a daily basis after their chicks hatch. Heinrich also includes anecdotes from an earlier time when he still lived in Vermont. Awakened one morning by the loud drumming of a male woodpecker on a nearby apple tree, the author wondered if perhaps he was seeking to attract a female. Surprisingly, when a female was drawn to the sound, he stopped drumming and flew away. The same behavior was repeated the following day. The author’s observations led him to conclude that the bird's drumming was not part of a mating ritual but rather a noisy advertisement of his nest-building skills. Vireos nesting near his cabin allowed him to observe how they deliberately reduced the number of eggs they were hatching to accommodate the reduced food supply after an unseasonal freeze. Heinrich explains that bird-watching has been an important part of his life since he was a boy on his family's farm. When he was 6, they moved from Germany to Maine. Finding familiar birds nesting “immediately made this place our home,” he writes.   An engaging memoir of the opportunities for doing scientific research without leaving one's own backyard. (Kirkus)

    New technologies have revealed secrets locked in prehistoric bones that no one could have previously predicted. We can now work out the color of dinosaurs, the force of their bite, their top speeds, and even how they cared for their young.Remarkable new fossil discoveries—giant sauropod dinosaur skeletons in Patagonia, dinosaurs with feathers in China, and a tiny dinosaur tail in Burmese amber—remain the lifeblood of modern paleobiology. Thanks to advances in technologies and methods, however, there has been a recent revolution in the scope of new information gleaned from such fossil finds.In Dinosaurs Rediscovered, leading paleontologist Michael J. Benton gathers together all the latest paleontological evidence, tracing the transformation of dinosaur study from its roots in antiquated natural history to an indisputably scientific field. Among other things, the book explores how dinosaur remains are found and excavated, and especially how paleontologists read the details of dinosaurs’ lives from their fossils—their colors, their growth, and even whether we will ever be able to bring them back to life. Benton’s account shows that, though extinct, dinosaurs are still very much a part of our world.

    Krause is a pioneer in the revolutionary new science of archaeogenetics, archaeology augmented by revolutionary DNA sequencing technology, which has allowed scientists to uncover a new version of human history reaching back more than 100,000 years. Using this technology to re-examine human bones from the distant past, Krause has been able to map not only the genetic profiles of the dead, but also their ancient journeys.In this concise narrative he tells us their long-forgotten stories of migration and intersection. It's well known that many human populations carry genetic material from Neanderthals; but, as Krause and his colleagues discovered, we also share DNA with a newly uncovered human form, the Denisovans. We know now that a wave of farmers from Anatolia migrated into Europe 8,000 years ago, essentially displacing the dark-skinned, blue-eyed hunter-gatherers who preceded them. The farmer DNA is one of the core genetic components of contemporary Europeans and European Americans. Though the first people to cross into North and South America have long been assumed to be primarily of East Asian descent, we now know that they also share DNA with contemporary Europeans and European Americans. Genetics has an unfortunate history of smuggling in racist ideologies, but our most cutting-edge science tells us that genetic categories in no way reflect national borders.Krause vividly introduces us to prehistoric cultures such as the Aurignacians, innovative artisans who carved animals, people, and even flutes from bird bones more than 40,000 years ago; the Varna, who buried their loved ones with gold long before the Pharaohs of Egypt; and the Gravettians, big-game hunters who were Europe's most successful early settlers until they perished in the ice age. This informed retelling of the human epic confirms that immigration and genetic mingling have always defined our species and that who we are is a question of culture not genetics.

    Settling in at a bonobo sanctuary in Congo's capital, Vanessa and her fiancé entered the world of a rare ape with whom we share 98.7 percent of our DNA. She soon discovered that many of the inhabitants of the sanctuary - ape and human alike - are refugees from unspeakable violence, yet bonobos live in a peaceful society in which females are in charge, war is nonexistent, and sex is as common and friendly as a handshake. A fascinating memoir of hope and adventure, Bonobo Handshake traces Vanessa's self-discovery as she finds herself falling deeply in love with her husband, the apes, and her new surroundings while probing life's greatest question: What ultimately makes us human? Courageous and extraordinary, this true story of revelation and transformation in a fragile corner of Africa is about looking past the differences between animals and ourselves, and finding in them the same extraordinary courage and will to survive. For Vanessa, it is about finding her own path as a writer and scientist, falling in love, and finding a home.

    After the horrors of the Nazi regime in WWII, the mainstream scientific world turned its back on eugenics and the study of racial difference. But a worldwide network of eugenicists founded journals and funded research, providing the kind of shoddy studies that were ultimately cited in Richard Hernstein's and Charles Murray's 1994 title, The Bell Curve, which purported to show differences in intelligence among races.Whether you think of racist science as bad science, evil science, alt-right science, or pseudoscience, why would any contemporary scientist imagine that gross inequality is a fact of nature, rather than of political history? Angela Saini's Superior connects the dots, laying bare the history, continuity, and connections of modern racist science, some more subtle than you might think.

    The idea of migration in prehistory, so long out of favor, is back on the agenda. New advances allow us to track human movement and the spread of crops, animals, and disease, and we can see the evidence of population crashes and rises, both continent-wide and locally. Visions of continuity have been replaced with a more dynamic view of Europe’s past, with one wave of migration followed by another, from the first human arrivals in Europe to the Vikings.Ancient DNA links Europe to its nearest neighbors. It is not a new idea that farming was brought from the Near East, but genetics now reveal an unexpectedly complex process in which farmers arrived not in one wave, but several. Even more unexpected is the evidence that the European gene pool was stirred vigorously many times after farming had reached most of Europe. Climate change played a part in this upheaval, but so did new inventions such as the c and wheeled vehicles. Genetic and linguistic clues also enhance our understanding of the upheavals of the Migration Period, the wanderings of steppe nomads, and the adventures of the Vikings.

    Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science.In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings.Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

    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.

    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.

    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 movies, in novels, in comic strips, and on television, we’ve all seen dinosaurs—or at least somebody’s educated guess of what they would look like. But what if it were possible to build, or grow, a real dinosaur, without finding ancient DNA? Jack Horner, the scientist who advised Steven Spielberg on Jurassic Park, and a pioneer in bringing paleontology into the twenty-first century, teams up with the editor of The New York Times’s Science Times section to reveal exactly what’s in store. In the 1980s, Horner began using CAT scans to look inside fossilized dinosaur eggs, and he and his colleagues have been delving deeper ever since. At North Carolina State University, Mary Schweitzer has extracted fossil molecules—proteins that survived 68 million years—from a Tyrannosaurus rex fossil excavated by Horner. These proteins show that T. rex and the modern chicken are kissing cousins. At McGill University, Hans Larsson is manipulating a chicken embryo to awaken the dinosaur within: starting by growing a tail and eventually prompting it to grow the forelimbs of a dinosaur. All of this is happening without changing a single gene. This incredible research is leading to discoveries and applications so profound they’re scary in the power they confer on humanity. How to Build a Dinosaur is a tour of the hot rocky deserts and air-conditioned laboratories at the forefront of this scientific revolution.

    The northern border was America’s primary border for centuries—much of the early history of the United States took place there—and to the tens of millions who live and work near the line, the region even has its own name: the northland.Travel writer Porter Fox spent three years exploring 4,000 miles of the border between Maine and Washington, traveling by canoe, freighter, car, and foot. In Northland, he blends a deeply reported and beautifully written story of the region’s history with a riveting account of his travels. Setting out from the easternmost point in the mainland United States, Fox follows explorer Samuel de Champlain’s adventures across the Northeast; recounts the rise and fall of the timber, iron, and rail industries; crosses the Great Lakes on a freighter; tracks America’s fur traders through the Boundary Waters; and traces the forty-ninth parallel from Minnesota to the Pacific Ocean.Fox, who grew up the son of a boat-builder in Maine’s northland, packs his narrative with colorful characters (Captain Meriwether Lewis, railroad tycoon James J. Hill, Chief Red Cloud of the Lakota Sioux) and extraordinary landscapes (Glacier National Park, the Northwest Angle, Washington’s North Cascades). He weaves in his encounters with residents, border guards, Indian activists, and militia leaders to give a dynamic portrait of the northland today, wracked by climate change, water wars, oil booms, and border security.

    Along the way, she meets biologists who are trying to preserve the world's rarest fish, which lives in a single tiny pool in the middle of the Mojave; engineers who are turning carbon emissions to stone in Iceland; Australian researchers who are trying to develop a super coral that can survive on a hotter globe; and physicists who are contemplating shooting tiny diamonds into the stratosphere to cool the earth.One way to look at human civilization, says Kolbert, is as a ten-thousand-year exercise in defying nature. In The Sixth Extinction, she explored the ways in which our capacity for destruction has reshaped the natural world. Now she examines how the very sorts of interventions that have imperiled our planet are increasingly seen as the only hope for its salvation.
