Why are a quarter of a billion sperm cells needed to fertilize one egg? Are women really fertile for only a few days each month? How long should women breast-feed? In How We Do It, primatologist Robert Martin draws on forty years of research to locate the origins of everything from sex cells to baby care—and to reveal what’s really �natural” when it comes to making and raising babies. He acknowledges that although it’s not realistic to reproduce like our ancestors did, there are surprising consequences to behavior we take for granted, such as bottle feeding, cesarean sections, and in vitro fertilization. How We Do It shows that once we understand our evolutionary past, we can consider what worked, what didn’t, and what it all means for the future of our species.

    An applied animal behaviorist and dog trainer with more than twenty years experience, Dr. Patricia McConnell looks at humans as just another interesting species, and muses about why we behave the way we do around our dogs, how dogs might interpret our behavior, and how to interact with our dogs in ways that bring out the best in our four-legged friends. After all, although humans and dogs share a remarkable relationship that is unique in the animal world, we are still two entirely different species, each shaped by our individual evolutionary heritage. Quite simply, humans are primates and dogs are canids (like wolves, coyotes, and foxes). Since we each speak a different native tongue, a lot gets lost in the translation.The Other End of the Leash demonstrates how even the slightest changes in your voice and the way you stand can help your dog understand what you want. Once you start to think about your own behavior from the perspective of your dog, you’ll understand why much of what appears to be doggy-disobedience is simply a case of miscommunication. Inside you will learn• How to use your voice so that your dog is more likely to do what you ask.• Why “getting dominance” over your dog is a bad idea.• Why “rough and tumble primate play” can lead to trouble–and how to play with your dog in ways that are fun and keep him out of trouble.• How dogs and humans share personality types–and why most dogs want to live with benevolent leaders rather than “alphawannabees!”In her own insightful, compelling style, Patricia McConnell combines wonderful true stories about people and dogs with a new, accessible scientific perspective on how they should behave around each other. This is a book that strives to help you make the most of life with your dog, and to prevent problems that might arise in that most rewarding of relationships.From the Hardcover edition.

    In presenting her case, Elaine Morgan forces scientists to question accepted theories of human evolution.

    Spanning continents and centuries, it is an in-depth look into the history and science of manliness. From speed and strength, to beauty and sex appeal, to bravado and wit, it examines how man today compares to his masculine ancestors. Peter McAllister set out to rebut the claim that man today is suffering from feminization and emasculation. He planned to use his skills as a paleoanthropologist and journalist to write a book demonstrating unequivocally that man today is a triumph---the result of a hard-fought evolutionary struggle toward greatness. As you will see, he failed. In nearly every category of manliness, modern man turned out to be not just matched, but bested, by his ancestors. Stung, McAllister embarked on a new mission. If his book couldn’t be a testament to modern male achievement, he decided, it would be a record of his failures. Manthropology, then, is a globe-spanning tour of the science of masculinity. It kicks off in Ice Age France, where a biomechanical analysis demonstrates that La Ferrassie 2, a Neanderthal woman discovered in the early 1900s, would cream 2004 World Arm Wrestling Federation champion Alexey Voyevoda in an arm wrestle. Then it moves on to medieval Serbia, showing how Slavic guslar poets (who were famously able to repeat a two thousand-line verse after just one hearing) would have destroyed Curtis Jackson, aka 50 Cent, in a battle rap. Finally, it takes the reader to the steaming jungles of modern equatorial Africa, where Aka Pygmy men are such super-dads, they even grow breasts to suckle their children. Now, that’s commitment. For modern man, the results of these investigations aren’t always pretty. But in its look at the history of men, Manthropology is unfailingly smart, informative, surprising, and entertaining.                         *** HOW DOES MODERN MAN STACK UP? Russian arm wrestling champion Alexey Voyevoda has a twenty-two-inch bicep and has curled more than two hundred and fifty pounds---with just one arm. But could he stand up in an arm wrestling match with an average Neanderthal male? Or, for that matter, a female? (p. 10)                       *** Today’s Ultimate Fighters compete in a sport where bouts routinely end with an unconscious loser splayed out on a blood-soaked canvas. But what would a match in the Octagon look like next to the Pankration bouts of the Ancient Greeks: a battleground or a playground? (p. 77)                       *** A modern army goes into battle with state-of-the-art technology and centuries of strategical insight. But for sheer determination, could they have bested Nero’s legions, who marched nearly two marathons a day for six days straight---each legionary carrying hundred-pound packs? (p. 99)                       *** There’s philological evidence that suggests Homer may not have written the Iliad; he may have rapped it. If 50 Cent had to face Homer in a rap battle, would he come out on top? (p. 160)                       *** Wilt Chamberlain is known for scoring on more than just the court. He claimed to have had as many as twenty thousand sexual encounters in his lifetime. Such conquest could only be matched by one of the world’s greatest conquerors: There is the evidence that approximately 32 million people are descended from Genghis Khan. (p. 248)

    “When there are gaps in understanding, confusion, and thus frustration, worry, and even anger are sure to follow.”Horses often grow up with these “gaps” in their training and education. When this happens, it can be difficult for the horse to be a willing partner to a human, and he may need to be “restarted”—that is, given a second chance to learn what is expected of him and how he can find a place where he is confident and comfortable both beside a handler and beneath a rider.In order to restart a horse successfully, we need to know how to retrace the steps the horse’s education has taken and find the path missed the first time around. In this book, the first of the expansive library of books penned by Rashid to include full-color photographs, readers are guided through practical steps for restarting horses, using Rashid’s simple yet impactful concepts derived from years of study of martial arts. We walk along with him as he proceeds with the quiet sorting of experience that provides the insight we need to give any horse the new beginning he deserves.

    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.

    In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

    If you could bring back to life a person or animal, what would you choose? Pilcher highlights her own choices from eras gone, including the King of the Dinosaurs, Tyrannosaurus rex, and the King of Rock 'n' Roll, Elvis Presley.From dinosaurs to dodos and Neanderthals, BRING BACK THE KING reveals how the burgeoning field of DNA science is being used to help resurrect individual animals (did your beloved Fido die before siring offspring?) and entire species from their stony graves. Pilcher describes current initiatives and future plans to restore deceased animals, and uses both science and willful irreverence to assess the ramifications of how these genetic Lazaruses might fare in their brave new world. Could a pet dinosaur be trained to roll over? Would Neanderthals enjoy opera? Could a returning dodo seek vengeance upon humanity?Blending the very latest de-extinction technology with cloning, and hard-core popular science with levity, BRING BACK THE KING will generate a lot of thoughtful discussion and a chuckle or two.

    The text presents a balanced, thorough introduction to the field of physical anthropology that also reflects the current state of the field. The heredity and evolution chapters (Chapters 1-5) have been expanded and updated to reflect the tremendous advances of molecular biology in all phases of physical anthropology, and the hominid evolution chapters (Chapters 8-11) have been reorganized and reinterpreted to reflect current academic thought springing from recent major finds. To make the text more accessible, the Sixth Edition includes many new visuals that, together with the many charts, helpful tables, multimedia, and engaging writing style, will bring the study of physical anthropology to life for today's student.

    He noted their general healthiness (and good teeth), and an absence of many of the diseases that plagued western cultures, such as scurvy, heart disease, and diabetes. Observing their dietary habits, he determined that their primary food was meat, both lean and fatty, and that their diets were very low in sugary or starchy carbohydrates. Was this meaty diet the key to their good health?The book chronicles a 1928 scientific experiment, conducted by the Russell Sage Institute of Pathology at Bellevue Hospital in New York, in which Stefansson and his colleague Dr. Karsten Andersen ate a meat-only diet for one year. The two men stayed healthy and fared very well, leading him to claim that we should reexamine our notion of what foods constitute a healthy diet.Later chapters promote the benefits of pemmican, a compact, portable, and high-energy food consisting of a concentrated mix of fat and protein made from dried lean bison meat, sometimes mixed with berries. Pemmican is like the original energy bar, and Stefansson spent considerable time and energy urging the military to adopt it for emergency rations.

    Now renewables are overtaking fossil fuels, with wind and solar energy becoming cheaper and more competitive every year. Growth in renewable energy will further accelerate as electric vehicles become less expensive than traditional automobiles. Understanding the implications of the energy transition will prepare us for the many changes ahead.This book is a primer for readers of all levels on the coming energy transition and its global consequences. Bruce Usher provides a concise yet comprehensive explanation for the extraordinary growth in wind and solar energy; the trajectory of the transition from fossil fuels to renewables; and the implications for industries, countries, and the climate. Written in a straightforward style with easy-to-understand visual aids, the book illuminates the strengths and weaknesses of renewable energy based on business fundamentals and analysis of the economic forces that have given renewables a tailwind. Usher dissects the winners and losers, illustrating how governments and businesses with a far-sighted approach will reap long-term benefits while others will trail behind. Alongside the business and finance case for renewable energy, he provides a timely illustration of the threat of catastrophic climate change and the perils of delay. A short and powerful guide to our energy present and future, this book makes it clear that, from both economic and environmental perspectives, there is no time to lose.

    The text, under the editorship of Stephen Jay Gould, provides a thorough understanding of the latest research and is accompanied by paintings prepared especially for this book. Never before has our planet's evolution been so clearly, so ingeniously explained. History is marked by disaster. The Book of Lifeexplains how mammals, having survived at least one of these disasters—the impact of a massive comet—luckily inherited the earth. Next came the rise of modern humans, who would shape the world as no creature has. As this fascinating history unfolds, gorgeous illustrations allow us to observe climate changes, tectonic plate movement, the spread of plant life, and the death of the dinosaurs. We discover the chains of animal survival, the causes and consequences of adaptation, and finally the environmental impact of human life.

    As the mosquito transformed the landscapes of civilization, humans were unwittingly required to respond to its piercing impact and universal projection of power.The mosquito has determined the fates of empires and nations, razed and crippled economies, and decided the outcome of pivotal wars, killing nearly half of humanity along the way. She (only females bite) has dispatched an estimated 52 billion people from a total of 108 billion throughout our relatively brief existence. As the greatest purveyor of extermination we have ever known, she has played a greater role in shaping our human story than any other living thing with which we share our global village.Imagine for a moment a world without deadly mosquitoes, or any mosquitoes, for that matter? Our history and the world we know, or think we know, would be completely unrecognizable.Driven by surprising insights and fast-paced storytelling, The Mosquito is the extraordinary untold story of the mosquito's reign through human history and her indelible impact on our modern world order.
