A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century.In 2013, Berger, a National Geographic Explorer-in-Residence, caught wind of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators--men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of "underground astronauts," Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known prehominids like Lucy, the famous Australopithecus, with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species, and they called it Homo naledi.The cave quickly proved to be the richest primitive hominid site ever discovered, full of implications that shake the very foundation of how we define what makes us human. Did this species come before, during, or after the emergence of Homo sapiens on our evolutionary tree? How did the cave come to contain nothing but the remains of these individuals? Did they bury their dead? If so, they must have had a level of self-knowledge, including an awareness of death. And yet those are the very characteristics used to define what makes us human. Did an equally advanced species inhabit Earth with us, or before us? Berger does not hesitate to address all these questions.Berger is a charming and controversial figure, and some colleagues question his interpretation of this and other finds. But in these pages, this charismatic and visionary paleontologist counters their arguments and tells his personal story: a rich and readable narrative about science, exploration, and what it means to be human.

    Enthusiastic and informal accounts of the exciting discoveries and fascinating observations made by naturalists in the study of the behavior of animals in their natural surroundings

    Prehistory has never been more exciting: New discoveries are overturning long-held theories left and right. Stone tools in Australia date back 65,000 years—a time when, we once thought, the first Sapiens had barely left Africa. DNA sequencing has unearthed a new hominid group—the Denisovans—and confirmed that crossbreeding with them (and Neanderthals) made Homo sapiens who we are today.A Pocket History of Human Evolution brings us up-to-date on the exploits of all our ancient relatives. Paleoanthropologist Silvana Condemi and science journalist François Savatier consider what accelerated our evolution: Was it tools, our “large” brains, language, empathy, or something else entirely? And why are we the sole surviviors among many early bipedal humans? Their conclusions reveal the various ways ancient humans live on today—from gossip as modern “grooming” to our gendered division of labor—and what the future might hold for our strange and unique species.

    When Kevin and Jeff die within nine months of one another—Kevin, a student enrolled in the University of Kentucky’s Reserve Officers’ Training Corps program, commits suicide and Jeff, who served in the Army as a second lieutenant, dies as a result of an IED attack in Iraq—Mark and his wife Carol find themselves reeling after the loss of two of their three children. As they begin to gather their bearings and contemplate a life without their sons, they must also come to terms with the terrible stigma that surrounds suicide in the military. This stigma is brought into high relief through the Grahams’ own experience of how their tight-knit military community marked their sons’ very different deaths. The Grahams commit themselves to fighting the military’s suicide epidemic and making sure that the families of troops who take their own lives receive the dignity and compassion that were the hallmarks of both of their sons’ lives. The Invisible Front is the story of their quest to do so. As Mark ascends the military hierarchy and eventually takes command of Fort Carson, Colorado—a sprawling base with one of the highest suicide rates in the armed forces—the Grahams assume a larger platform from which to work to reduce the stigma that surrounds mental health in the military and to develop new ways of keeping troubled troops from killing themselves. Their efforts put them in direct conflict with an entrenched military bureaucracy that considered mental health problems to be a display of weakness and that refused to acknowledge, until far too late, the severity of its suicide problem. The Grahams refuse to back down, using the pain and grief that their sons’ deaths inspired to fight to change the institution that is the cornerstone of their lives.  Yochi Dreazen, an award-winning journalist who has covered the military since 1999, has been granted remarkable access to the Graham family and, as a result, is able to tell the story of Kevin and Jeff’s legacy in the full context of America’s two long wars. The Invisible Front places the Graham family’s story against the backdrop of the military’s suicide spike, caused in part by the military’s own institutional shortcomings and its resistance to change. With great sympathy and deep understanding, The Invisible Front examines America's problematic treatment of its soldiers and offers the Graham family’s work as a new way of understanding how to minimize the risk of suicide, substance abuse and PTSD in the military.

    Today, unfortunately, the traditional place of mathematics in education is in grave danger. The teaching and learning of mathematics has degenerated into the realm of rote memorization, the outcome of which leads to satisfactory formal ability but does not lead to real understanding or to greater intellectual independence. This new edition of Richard Courant's and Herbert Robbins's classic work seeks to address this problem. Its goal is to put the meaning back into mathematics.Written for beginners and scholars, for students and teachers, for philosophers and engineers, What is Mathematics? Second Edition is a sparkling collection of mathematical gems that offers an entertaining and accessible portrait of the mathematical world. Covering everything from natural numbers and the number system to geometrical constructions and projective geometry, from topology and calculus to matters of principle and the Continuum Hypothesis, this fascinating survey allows readers to delve into mathematics as an organic whole rather than an empty drill in problem solving. With chapters largely independent of one another and sections that lead upward from basic to more advanced discussions, readers can easily pick and choose areas of particular interest without impairing their understanding of subsequent parts.Brought up to date with a new chapter by Ian Stewart, What is Mathematics? Second Edition offers new insights into recent mathematical developments and describes proofs of the Four-Color Theorem and Fermat's Last Theorem, problems that were still open when Courant and Robbins wrote this masterpiece, but ones that have since been solved.Formal mathematics is like spelling and grammar - a matter of the correct application of local rules. Meaningful mathematics is like journalism - it tells an interesting story. But unlike some journalism, the story has to be true. The best mathematics is like literature - it brings a story to life before your eyes and involves you in it, intellectually and emotionally. What is Mathematics is like a fine piece of literature - it opens a window onto the world of mathematics for anyone interested to view.

    What fans may not know is that she learned English from Eddie Murphy, got her American citizenship so she could be a beauty queen, and used to have a bad habit of stealing cars for fun. Giuliana bares this and so much more in her hilarious, warm, and inspiring memoir, Going Off Script. From a young age she dreamed of being a TV anchorwoman but, because of her inclination toward mischief and away from schoolwork, her path to her dream job was far from straight. After a fateful (and mortifying) encounter with the late Senator Ted Kennedy, she learned that Hollywood news was where she belonged. Thankfully for readers, this epiphany led her to a bounty of LA misadventures (featuring notables such as Johnny Depp, Leonardo DiCaprio, and Russell Crowe) and an entertaining behind-the-scenes perspective on what our favorite celebrities are really like. In spite of her glamorous Hollywood life, however, Giuliana could not escape some rockier times, including her battles with infertility and breast cancer. Here, for the first time, she reveals the whole truth behind her well-publicized struggles, and the highly controversial decisions she had to make. And, of course, at the heart of it all are the two loves of her life who keep her strong through everything, her husband Bill and her son, Duke. Candid, funny, and poignant, Going Off Script is an autobiography that proves you don’t always have to follow the rules to get the life you’ve always dreamed of.

    While maintaining the hallmark features of previous editions, the Fourth Edition has been completely updated. It includes new Key Concepts at the beginning of each chapter and annotated further reading at the conclusion of each chapter, to help readers navigate the wealth of information in this subject.The text has been restructured so genomic technologies are integrated throughout, and next generation sequencing is included. Genetic testing, screening, approaches to therapy, personalized medicine, and disease models have been brought together in one section. Coverage of cell biology including stem cells and cell therapy, studying gene function and structure, comparative genomics, model organisms, noncoding RNAs and their functions, and epigenetics have all been expanded.

    A defiant atheist, Chapman is confronted not only by the fundamentalist beliefs that continue to banish the theory of evolution but by his own spiritual malaise as the outward journey becomes an inward quest, a tragicomic "accidental memoir"."First there was Charles Darwin, two yards long and nobody's fool. Then there was his son, my great-grandfather, Sir Francis Darwin, an eminent botanist. Then came my grandmother Frances, a modest poet who spent a considerable amount of time in rest-homes for depression From her issued my beloved mother, Clare, who was extremely short, failed to complete medical school, and eventually became an alcoholic. Then we get down to me. I'm in the movie business."Trials of the Monkey combines travel writing and reportage, as Chapman records his encounters in the South, with history and the accidental memoir of a man full of mid-life doubts in a genre-breaking first book that is darkly funny, provocative and poignant.

    In the normal condition the two look the same, but in this disorder one is malformed and shrunken beyond recognition. The result is a shortened life span, higher mortality at all ages, an inability to reproduce, premature hair loss, and brain defects variously resulting in attention deficit, hyperactivity, conduct disorder, hypersexuality, and an enormous excess of both outward and self-directed aggression.It is called maleness.Melvin Konner traces the arc of evolution to explain the relationships between women and men. With patience and wit he explores the knotty question of whether men are necessary in the biological destiny of the human race. He draws on multiple, colorful examples from the natural world — such as the mating habits of the octopus, black widow, angler fish, and jacana — and argues that maleness in humans is hardly necessary to the survival of the species.In characteristically humorous and engaging prose, Konner sheds light on our biologically different identities, while noting the poignant exceptions that challenge the male/female divide. We meet hunter-gatherers such as those in Botswana, whose culture gave women a prominent place, invented the working mother, and respected women’s voices around the fire. Recent human history has upset this balance, as a dense world of war fostered extreme male dominance. But our species has been recovering over the past two centuries, and an unstoppable move toward equality is afoot. It will not be the end of men, but it will be the end of male supremacy and a better, wiser world for women and men alike.

    But how did we acquire the most advanced form of communication on Earth? Daniel L. Everett, a “bombshell” linguist and “instant folk hero” (Tom Wolfe, Harper’s), provides in this sweeping history a comprehensive examination of the evolutionary story of language, from the earliest speaking attempts by hominids to the more than seven thousand languages that exist today.Although fossil hunters and linguists have brought us closer to unearthing the true origins of language, Daniel Everett’s discoveries have upended the contemporary linguistic world, reverberating far beyond academic circles. While conducting field research in the Amazonian rainforest, Everett came across an age-old language nestled amongst a tribe of hunter-gatherers. Challenging long-standing principles in the field, Everett now builds on the theory that language was not intrinsic to our species. In order to truly understand its origins, a more interdisciplinary approach is needed—one that accounts as much for our propensity for culture as it does our biological makeup.Language began, Everett theorizes, with Homo Erectus, who catalyzed words through culturally invented symbols. Early humans, as their brains grew larger, incorporated gestures and voice intonations to communicate, all of which built on each other for 60,000 generations. Tracing crucial shifts and developments across the ages, Everett breaks down every component of speech, from harnessing control of more than a hundred respiratory muscles in the larynx and diaphragm, to mastering the use of the tongue. Moving on from biology to execution, Everett explores why elements such as grammar and storytelling are not nearly as critical to language as one might suspect.In the book’s final section, Cultural Evolution of Language, Everett takes the ever-debated “language gap” to task, delving into the chasm that separates “us” from “the animals.” He approaches the subject from various disciplines, including anthropology, neuroscience, and archaeology, to reveal that it was social complexity, as well as cultural, physiological, and neurological superiority, that allowed humans—with our clawless hands, breakable bones, and soft skin—to become the apex predator.How Language Began ultimately explains what we know, what we’d like to know, and what we likely never will know about how humans went from mere communication to language. Based on nearly forty years of fieldwork, Everett debunks long-held theories by some of history’s greatest thinkers, from Plato to Chomsky. The result is an invaluable study of what makes us human.

    Like Jared Diamond's Guns, Germs and Steel, Mapping Human History is a groundbreaking synthesis of science and history. Drawing on a wide range of sources, including the latest genetic research, linguistic evidence, and archaeological findings, Olson reveals the surprising unity among modern humans and "demonstrates just how naive some of our ideas about our human ancestry have been" (Discover).Olson offers a genealogy of all humanity, explaining, for instance, why everyone can claim Julius Caesar and Confucius as forebears. Olson also provides startling new perspectives on the invention of agriculture, the peopling of the Americas, the origins of language, the history of the Jews, and more. An engaging and lucid account, Mapping Human History will forever change how we think about ourselves and our relations with others.
