A breakthrough theory that tools and technology are the real drivers of human evolution Although humans are one of the great apes, along with chimpanzees, gorillas, and orangutans, we are remarkably different from them. Unlike our cousins who subsist on raw food, spend their days and nights outdoors, and wear a thick coat of hair, humans are entirely dependent on artificial things, such as clothing, shelter, and the use of tools, and would die in nature without them. Yet, despite our status as the weakest ape, we are the masters of this planet. Given these inherent deficits, how did humans come out on top? In this fascinating new account of our origins, leading archaeologist Timothy Taylor proposes a new way of thinking about human evolution through our relationship with objects. Drawing on the latest fossil evidence, Taylor argues that at each step of our species' development, humans made choices that caused us to assume greater control of our evolution. Our appropriation of objects allowed us to walk upright, lose our body hair, and grow significantly larger brains. As we push the frontiers of scientific technology, creating prosthetics, intelligent implants, and artificially modified genes, we continue a process that started in the prehistoric past, when we first began to extend our powers through objects. Weaving together lively discussions of major discoveries of human skeletons and artifacts with a reexamination of Darwin's theory of evolution, Taylor takes us on an exciting and challenging journey that begins to answer the fundamental question about our existence: what makes humans unique, and what does that mean for our future? |

This account of one man’s tempestuous relationship with the hawk he trained is at once a comedy of errors, a classic of nature writing, and one of the best glimpses into the world of falconry. The predecessor to Helen Macdonald’s H is for Hawk , T. H. White’s nature writing classic, The Goshawk , asks the age-old question: what is it that binds human beings to other animals? White, the author of The Once and Future King and Mistress Masham’s Repose, was a young writer who found himself rifling through old handbooks of falconry. A particular sentence—“the bird reverted to a feral state”—seized his imagination and he immediately wrote to Germany to acquire a young goshawk. Gos, as White named the bird, was ferocious and free, and White had no idea how to break him in beyond the ancient of depriving him of sleep. Slowly man and bird entered a state of delirium and intoxication, of attraction and repulsion that looks very much like love. White kept a daybook describing his volatile relationship with Gos—at once a tale of obsession, a comedy of errors, and a hymn to the hawk. It was this that became The Goshawk , one of modern literature’s most memorable and surprising encounters with the wilderness—as it exists both within us and without. |

A 2021 Mathical Honor Book: “One of the best math teachers on the planet. His book is as buoyant, open-hearted, and energetic as he is.” —Steven Strogatz,  New York Times –bestselling author of  Infinite Powers: How Calculus Reveals the Secrets of the Universe Why aren’t left-handers extinct? What makes a rainbow round? How is a pancreas like a pendulum? These may not look like math questions, but they are—because they all have to do with patterns. And mathematics, at heart, is the study of patterns. That realization changed Eddie Woo’s life—by turning the “dry” subject he dreaded in high school into a boundless quest for discovery. Now an award-winning math teacher and a YouTuber with nearly two million subscribers, Woo sees patterns everywhere: in the “branches” of blood vessels and lightning, in the growth of a savings account and a sunflower, even in his morning cup of tea! Here are twenty-six bite-size chapters on the hidden mathematical marvels that encrypt our email, enchant our senses, and even keep us alive—from the sine waves we hear as “music” to the mysterious golden ratio. This book will change your mind about what math can be. We are all born mathematicians—and it’s a numberful world. “Introduces mathematical vocabulary in a fun and approachable way. . . . A gentle but enthusiastic introduction to a wide variety of interesting mathematical topics.” —Mathematical Association of America “Lighthearted and delightful . . . the ideal guide to math’s multi-patterned treasures.” — Foreword Reviews Publisher’s note: It’s a Numberful World was published in Australia under the title Woo's Wonderful World of Maths. |

NATIONAL BESTSELLER • The triumphant true story of a woman who rode her horse across America in the 1950s, fulfilling her dying wish to see the Pacific Ocean, from the #1 New York Times bestselling author of The Perfect Horse and The Eighty-Dollar Champion “The gift Elizabeth Letts has is that she makes you feel you are the one taking this trip. This is a book we can enjoy always but especially need now.”—Elizabeth Berg, author of The Story of Arthur Truluv In 1954, sixty-three-year-old Maine farmer Annie Wilkins embarked on an impossible journey. She had no money and no family, she had just lost her farm, and her doctor had given her only two years to live. But Annie wanted to see the Pacific Ocean before she died. She ignored her doctor’s advice to move into the county charity home. Instead, she bought a cast-off brown gelding named Tarzan, donned men’s dungarees, and headed south in mid-November, hoping to beat the snow. Annie had little idea what to expect beyond her rural crossroads; she didn’t even have a map. But she did have her ex-racehorse, her faithful mutt, and her own unfailing belief that Americans would treat a stranger with kindness. Annie, Tarzan, and her dog, Depeche Toi, rode straight into a world transformed by the rapid construction of modern highways. Between 1954 and 1956, the three travelers pushed through blizzards, forded rivers, climbed mountains, and clung to the narrow shoulder as cars whipped by them at terrifying speeds. Annie rode more than four thousand miles, through America’s big cities and small towns. Along the way, she met ordinary people and celebrities—from Andrew Wyeth (who sketched Tarzan) to Art Linkletter and Groucho Marx. She received many offers—a permanent home at a riding stable in New Jersey, a job at a gas station in rural Kentucky, even a marriage proposal from a Wyoming rancher. In a decade when car ownership nearly tripled, when television’s influence was expanding fast, when homeowners began locking their doors, Annie and her four-footed companions inspired an outpouring of neighborliness in a rapidly changing world. |

A guide to listening to songbirds—the key to observing nature in a whole new way. Includes audio of bird vocalizations!   A lifelong birder, tracker, and naturalist, Jon Young is guided in his work and teaching by three basic premises: the robin, junco, and other songbirds know everything important about their environment, be it backyard or forest; by tuning in to their vocalizations and behavior, we can acquire much of this wisdom for our own pleasure and benefit; and the birds’ companion calls and warning alarms are just as important as their songs.   Birds are the sentries of—and our key to understanding the world beyond our front door. By learning to remain quiet and avoid disturbing the environment, we can heed the birds and acquire an amazing new level of awareness. We are welcome in their habitat. The birds don’t fly away. The larger animals don’t race off. No longer hapless intruders, we now find, see, and engage the deer, the fox, the red-shouldered hawk—even the elusive, whispering wren.   Deep bird language is an ancient discipline, perfected by Native peoples the world over. Finally, science is catching up. This groundbreaking book unites the indigenous knowledge, the latest research, and the author’s own experience of four decades in the field to lead us toward a deeper connection to the animals and, in the end, ourselves.   “He can sit still in his yard, watching and listening for the moment when robins and other birds no longer perceive him as a threat. Then he can begin to hear what the birds say to each other, warning about nearby hawks, cats, or competitors. Young’s book will teach you how you, too, can understand birds and their fascinating behaviors.” — BirdWatching   “Here is the ancestral wisdom passed down from Apache elder Stalking Wolf to renowned tracker Tom Brown to Jon Young himself, who in turn passes on to the reader the art of truly listening to the avian soundscape. With all senses more finely tuned, you’ll find yourself more aware of your surroundings, slowing down, and reconnecting with a native intelligence and love of the natural world that lies deep within each of us.” —Donald Kroodsma, author of The Singing Life of Birds  and  Birdsong by the Seasons |

The #1 international bestseller on climate change that’s been endorsed by policy makers, scientists, writers, and energy executives around the world.   Tim Flannery’s The Weather Makers contributed in bringing the topic of global warming to worldwide prominence. For the first time, a scientist provided an accessible and comprehensive account of the history, current status, and future impact of climate change, writing what has been acclaimed by reviewers everywhere as the definitive book on global warming.   With one out of every five living things on this planet committed to extinction by the levels of greenhouse gases that will accumulate in the next few decades, we are reaching a global climatic tipping point. The Weather Makers is both an urgent warning and a call to arms, outlining the history of climate change, how it will unfold over the next century, and what we can do to prevent a cataclysmic future.   Originally somewhat of a global warming skeptic, Tim Flannery spent several years researching the topic and offers a connect-the-dots approach for a reading public who has received patchy or misleading information on the subject. Pulling on his expertise as a scientist to discuss climate change from a historical perspective, Flannery also explains how climate change is interconnected across the planet.   This edition includes a new afterword by the author.   “An authoritative, scientifically accurate book on global warming that sparkles with life, clarity, and intelligence.” — The Washington Post |

This "eye-opening and essential" book (Bill Gates) will transform how you see our biggest environmental problems—and explains how we can solve them. It’s become common to tell kids that they’re going to die from climate change. We are constantly bombarded by doomsday headlines that tell us the soil won’t be able to support crops, fish will vanish from our oceans, and that we should reconsider having children. But in this bold, radically hopeful book, data scientist Hannah Ritchie argues that if we zoom out, a very different picture emerges. In fact, the data shows we’ve made so much progress on these problems that we could be on track to achieve true sustainability for the first time in human history. Did you know that: Carbon emissions per capita are actually down Deforestation peaked back in the 1980s The air we breathe now is vastly improved from centuries ago And more people died from natural disasters a hundred years ago? Packed with the latest research, practical guidance, and enlightening graphics, this book will make you rethink almost everything you’ve been told about the environment. Not the End of the World will give you the tools to understand our current crisis and make lifestyle changes that actually have an impact. Hannah cuts through the noise by outlining what works, what doesn’t, and what we urgently need to focus on so we can leave a sustainable planet for future generations.       These problems are big. But they are solvable. We are not doomed. We can build a better future for everyone. Let’s turn that opportunity into reality.   |

Why do we do the things we do? Over a decade in the making, this game-changing book is Robert Sapolsky's genre-shattering attempt to answer that question as fully as perhaps only he could, looking at it from every angle. Sapolsky's storytelling concept is delightful but it also has a powerful intrinsic logic: he starts by looking at the factors that bear on a person's reaction in the precise moment a behavior occurs, and then hops back in time from there, in stages, ultimately ending up at the deep history of our species and its genetic inheritance. And so the first category of explanation is the neurobiological one. What goes on in a person's brain a second before the behavior happens? Then he pulls out to a slightly larger field of vision, a little earlier in time: What sight, sound, or smell triggers the nervous system to produce that behavior? And then, what hormones act hours to days earlier to change how responsive that individual is to the stimuli which trigger the nervous system? By now, he has increased our field of vision so that we are thinking about neurobiology and the sensory world of our environment and endocrinology in trying to explain what happened. Sapolsky keeps going--next to what features of the environment affected that person's brain, and then back to the childhood of the individual, and then to their genetic makeup. Finally, he expands the view to encompass factors larger than that one individual. How culture has shaped that individual's group, what ecological factors helped shape that culture, and on and on, back to evolutionary factors thousands and even millions of years old. The result is one of the most dazzling tours de horizon of the science of human behavior ever attempted, a majestic synthesis that harvests cutting-edge research across a range of disciplines to provide a subtle and nuanced perspective on why we ultimately do the things we do...for good and for ill. Sapolsky builds on this understanding to wrestle with some of our deepest and thorniest questions relating to tribalism and xenophobia, hierarchy and competition, morality and free will, and war and peace. Wise, humane, often very funny, Behave is a towering achievement, powerfully humanizing, and downright heroic in its own right. |

"THE ULTIMATE DINOSAUR BIOGRAPHY," hails Scientific American: A thrilling new history of the age of dinosaurs, from one of our finest young scientists. "A masterpiece of science writing." —Washington Post A New York Times Bestseller • Goodreads Choice Awards Winner • A BEST BOOK OF THE YEAR: Smithsonian, Science Friday, The Times (London), Popular Mechanics, Science News "This is scientific storytelling at its most visceral, striding with the beasts through their Triassic dawn, Jurassic dominance, and abrupt demise in the Cretaceous." —Nature The dinosaurs. Sixty-six million years ago, the Earth’s most fearsome creatures vanished. Today they remain one of our planet’s great mysteries. Now The Rise and Fall of the Dinosaurs reveals their extraordinary, 200-million-year-long story as never before. In this captivating narrative (enlivened with more than seventy original illustrations and photographs), Steve Brusatte, a young American paleontologist who has emerged as one of the foremost stars of the field—naming fifteen new species and leading groundbreaking scientific studies and fieldwork—masterfully tells the complete, surprising, and new history of the dinosaurs, drawing on cutting-edge science to dramatically bring to life their lost world and illuminate their enigmatic origins, spectacular flourishing, astonishing diversity, cataclysmic extinction, and startling living legacy. Captivating and revelatory, The Rise and Fall of the Dinosaurs is a book for the ages. Brusatte traces the evolution of dinosaurs from their inauspicious start as small shadow dwellers—themselves the beneficiaries of a mass extinction caused by volcanic eruptions at the beginning of the Triassic period—into the dominant array of species every wide-eyed child memorizes today, T. rex, Triceratops, Brontosaurus, and more. This gifted scientist and writer re-creates the dinosaurs’ peak during the Jurassic and Cretaceous, when thousands of species thrived, and winged and feathered dinosaurs, the prehistoric ancestors of modern birds, emerged. The story continues to the end of the Cretaceous period, when a giant asteroid or comet struck the planet and nearly every dinosaur species (but not all) died out, in the most extraordinary extinction event in earth’s history, one full of lessons for today as we confront a “sixth extinction.” Brusatte also recalls compelling stories from his globe-trotting expeditions during one of the most exciting eras in dinosaur research—which he calls “a new golden age of discovery”—and offers thrilling accounts of some of the remarkable findings he and his colleagues have made, including primitive human-sized tyrannosaurs; monstrous carnivores even larger than T. rex; and paradigm-shifting feathered raptors from China. An electrifying scientific history that unearths the dinosaurs’ epic saga, The Rise and Fall of the Dinosaurs will be a definitive and treasured account for decades to come. Includes 75 images, world maps of the prehistoric earth, and a dinosaur family tree. |

#1 NATIONAL BESTSELLER WINNER OF THE BAILLIE GIFFORD PRIZE FOR NONFICTION • FINALIST FOR THE HILARY WESTON WRITERS' TRUST PRIZE FOR NONFICTION • FINALIST FOR THE NATIONAL BOOK AWARD IN NONFICTION • ONE OF THE NEW YORK TIMES ’ TOP TEN BOOKS OF THE YEAR • A stunning account of the colossal wildfire at Fort McMurray, and a panoramic exploration of the rapidly changing relationship between fire and humankind from the award-winning, best-selling author of The Tiger and The Golden Spruce . Named a Best Book of the Year by The Guardian • TIME • The Globe and Mail • The New Yorker • Financial Times • CBC • Smithsonian • Air Mail Weekly • Slate • NPR • Toronto Star • The Washington Post • The Times • Orion Magazine In May 2016, Fort McMurray, the hub of Canada's petroleum industry and America's biggest foreign supplier, was overrun by wildfire. The multi-billion-dollar disaster melted vehicles, turned entire neighborhoods into firebombs, and drove 88,000 people from their homes in a single afternoon. Through the lens of this apocalyptic conflagration—the wildfire equivalent of Hurricane Katrina—John Vaillant warns that this was not a unique event but a shocking preview of what we must prepare for in a hotter, more flammable world.     For hundreds of millennia, fire has been a partner in our evolution, shaping culture, civilization, and, very likely, our brains. Fire has enabled us to cook our food, defend and heat our homes, and power the machines that drive our titanic economy. Yet this volatile energy source has always threatened to elude our control, and in our new age of intensifying climate change, we are seeing its destructive power unleashed in previously unimaginable ways.     With masterly prose and a cinematic eye, Vaillant takes us on a riveting journey through the intertwined histories of North America's oil industry and the birth of climate science, to the unprecedented devastation wrought by modern forest fires, and into lives forever changed by these disasters. John Vaillant's urgent work is a book for—and from—our new century of fire, which has only just begun. |

An inspiring true-life survival story set in the remote backcountry of the Canadian Rockies. In August 2017, 32-year-old Jeremy Evans endured multiple ferocious attacks by a protective female grizzly bear while hunting in the Alberta wilderness. Jeremy’s injuries were massive, his scalp and face destroyed, an eye and his jaw dangling down. The tendons on one leg had been fully severed during the mauling. His hands were damaged where he had physically fought the bear. It was more than a dozen kilometres to where he had parked his truck in darkness early that morning and absolutely no one was near. Thoughts of his wife and their eight-month-old daughter consumed Jeremy as he stumbled and crawled for hours back to his truck, before driving himself several kilometres to a backcountry lodge for help. All the while, Jeremy thought of his young family and the upcoming sixth wedding anniversary that he feared he might never be able to celebrate. Mauled carefully details what happened deep in an Alberta forest where few modern humans tread. Jeremy’s miraculous recovery and life lessons learned when so close to death show that human determination can defy the greatest of odds, and that setting small goals along the road to recovery can lead to remarkable achievements. Despite the traumatic stress the encounter produced, Jeremy holds no animosity toward the bear and still enjoys spending time in the backcountry. To him the grizzly was doing what the best parents do: protect their young. |

In The Hidden Life of Trees , Peter Wohlleben shares his deep love of woods and forests and explains the amazing processes of life, death, and regeneration he has observed in the woodland and the amazing scientific processes behind the wonders of which we are blissfully unaware. Much like human families, tree parents live together with their children, communicate with them, and support them as they grow, sharing nutrients with those who are sick or struggling and creating an ecosystem that mitigates the impact of extremes of heat and cold for the whole group. As a result of such interactions, trees in a family or community are protected and can live to be very old. In contrast, solitary trees, like street kids, have a tough time of it and in most cases die much earlier than those in a group. Drawing on groundbreaking new discoveries, Wohlleben presents the science behind the secret and previously unknown life of trees and their communication abilities; he describes how these discoveries have informed his own practices in the forest around him. As he says, a happy forest is a healthy forest, and he believes that eco-friendly practices not only are economically sustainable but also benefit the health of our planet and the mental and physical health of all who live on Earth. |

A groundbreaking tour of the human mind that illuminates the biological nature of our inner worlds and emotions, through gripping, moving—and, at times, harrowing—clinical stories “[A] scintillating and moving analysis of the human brain and emotions.”— Nature “Beautifully connects the inner feelings within all human beings to deep insights from modern psychiatry and neuroscience.”—Robert Lefkowitz, Nobel Laureate Karl Deisseroth has spent his life pursuing truths about the human mind, both as a renowned clinical psychiatrist and as a researcher creating and developing the revolutionary field of optogenetics, which uses light to help decipher the brain’s workings. In Projections, he combines his knowledge of the brain’s inner circuitry with a deep empathy for his patients to examine what mental illness reveals about the human mind and the origin of human feelings—how the broken can illuminate the unbroken. Through cutting-edge research and gripping case studies from Deisseroth’s own patients, Projections tells a larger story about the material origins of human emotion, bridging the gap between the ancient circuits of our brain and the poignant moments of suffering in our daily lives. The stories of Deisseroth’s patients are rich with humanity and shine an unprecedented light on the self—and the ways in which it can break down. A young woman with an eating disorder reveals how the mind can rebel against the brain’s most primitive drives of hunger and thirst; an older man, smothered into silence by depression and dementia, shows how humans evolved to feel not only joy but also its absence; and a lonely Uighur woman far from her homeland teaches both the importance—and challenges—of deep social bonds. Illuminating, literary, and essential, Projections is a revelatory, immensely powerful work. It transforms our understanding not only of the brain but of ourselves as social beings—giving vivid illustrations through science and resonant human stories of our yearning for connection and meaning. |

Through riveting personal stories and the latest research, Harvard evolutionary biologist Carole Hooven shows how testosterone drives the behavior of the sexes apart and how understanding the science behind this hormone is empowering for all. Since antiquity—from the eunuchs in the royal courts of ancient China to the booming market for “elixirs of youth” in nineteenth-century Europe—humans have understood that typically masculine behavior depends on testicles, the main source of testosterone in males. Which sex has the highest rates of physical violence, hunger for status, and desire for a high number of sex partners? Just follow the testosterone. Although we humans can study and reflect on our own behavior, we are also animals, the products of millions of years of evolution. Fascinating research on creatures from chimpanzees to spiny lizards shows how high testosterone helps males out-reproduce their competitors. And men are no exception. While most people agree that sex differences in human behavior exist, they disagree about the reasons. But the science is clear: testosterone is a potent force in human society, driving the bodies and behavior of the sexes apart. But, as Hooven shows in T , it does so in concert with genes and culture to produce a vast variety of male and female behavior. And, crucially, the fact that many sex differences are grounded in biology provides no support for restrictive gender norms or patriarchal values. In understanding testosterone, we better understand ourselves and one another—and how we might build a fairer, safer society. |

“A landmark book in the science of emotions and its implications for ethics and human universals.”—Library Journal, starred review In this startling study of human emotion, Dacher Keltner investigates an unanswered question of human evolution: If humans are hardwired to lead lives that are “nasty, brutish, and short,” why have we evolved with positive emotions like gratitude, amusement, awe, and compassion that promote ethical action and cooperative societies? Illustrated with more than fifty photographs of human emotions, Born to Be Good takes us on a journey through scientific discovery, personal narrative, and Eastern philosophy. Positive emotions, Keltner finds, lie at the core of human nature and shape our everyday behavior—and they just may be the key to understanding how we can live our lives better.
