The renowned family of paleontologists—Louis Leakey, Mary Leakey, and their son Richard Leakey—has vastly expanded our understanding of human evolution. The Origin of Humankind is Richard Leakey’s personal view of the development of Homo Sapiens. At the heart of his new picture of evolution is the introduction of a heretical notion: once the first apes walked upright, the evolution of modern humans became possible and perhaps inevitable. From this one evolutionary step comes all the other evolutionary refinements and distinctions that set the human race apart from the apes. In fascinating sections on how and why modern humans developed a social organization, culture, and personal behavior, Leakey has much of interest to say about the development of art, language, and human consciousness.

    In 1985 Hans von Ohain, the scientist who pioneered Nazi Germany's efforts to build a jet plane, posed the question: 'Would World War II have occured if the Luftwaffe knew it faced operational British jets instead of Spitfires?' He immediately answered, 'I, for one, think not.'Frank Whittle, working-class outsider and self-taught enthusiast, had worked out the blueprint of a completely new type of engine in 1929, only for his ideas to be blocked by bureaucratic opposition until the outbreak of war in 1939. The importance of his work was recognized too late by the government for his revolutionary engine to play a major part in World War II. After the war Whittle's dream of civilian jet-powered aircraft became a reality and Britain enjoyed a golden age of 1950's jet-powered flight.Drawing on Whittle's extensive private papers, Campbell-Smith tells the story of a stoic and overlooked British hero, a tantalizing tale of 'what might have been'.

    By focusing mostly on the birds Charles Darwin observed, and by brilliantly mining his lesser-known writings, Haupt pens a startlingly fresh exploration of the man's genius that invites readers to look at the world with new eyes.

    Our fortunes were once founded on sheep, and this book tells a story of wool and money and history, of merchants and farmers and shepherds, of English yeomen and how they got their freedom, and above all, of the soil. Sheep have helped define our culture and topography, impacting on everything from accent and idiom, architecture, roads and waterways, to social progression and wealth. With his eye for the idiosyncratic, Philip meets the native breeds that thrive in this country; he tells stories about each breed, meets their shepherds and owners, learns about their past - and confronts the present realities of sheep farming. Along the way, Philip meets the people of the countryside and their many professions: the mole-catchers, the stick-makers, the tobacco-twisters and clog-wrights. He explores this artisan heritage as he re-discovers the countryside, and finds a lifestyle parallel to modern existence, struggling to remain unchanged - and at its heart, always sheep.

    And although we want it to last forever, we know that nothing ever does. In the early 1990's David Hartwig, a Texas cowboy with dreams of rodeo stardom, struggled to support his family and, in doing so, discovered a dog with talents he himself could never realize.Together with David, Skidboot shot to international fame, despite tumultuous events that nearly sent this rural family to the brink. Skidboot is a true story of loyalty, sacrifice, discipline, love, and companionship. Skidboot--there will never be another.

    After Congress viewed photos of Yosemite, President Lincoln was moved to sign a bill that paved the way for the U.S. National Park Service, which was founded in 1916 and is now celebrating its centennial. In Treasured Lands: A Photographic Odyssey Through America's National Parks, photographer QT Luong pays tribute to the millions of acres of protected wilderness in our country's 59 national parks. Luong, who is featured in Ken Burns's and Dayton Duncan's documentary The National Parks: America's Best Idea, is one the most prolific photographers working in the national parks and the only one to have made large-format photographs in each of them. In an odyssey that spanned more than 20 years and 300 visits, Luong focused his lenses on iconic landscapes and rarely seen remote views, presenting his journey in this sumptuous array of more than 500 breathtaking images. Accompanying the collection of scenic masterpieces is a guide that includes maps of each park, as well as extended captions that detail where and how the photographs were made. Designed to inspire visitors to connect with the parks and invite photographers to re-create these landscapes, the guide also provides anecdotal observations that give context to the pictures and convey the sheer scope of Luong's extraordinary odyssey. Including an introduction by award-winning author and documentary filmmaker Dayton Duncan, Treasured Lands is a rich visual tour of the U.S. National Parks and an invaluable guide from a photographer who hiked - or paddled, dived, skied, snowshoed, and climbed - each park, shooting in all kinds of terrain, in all seasons, and at all times of day. QT Luong's timeless gallery of the nation's most revered landscapes beckons to nature lovers, armchair travelers, and photography enthusiasts alike, keeping America's natural wonders within reach.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    But evolutionary biologists also point out many examples of contingency, cases where the tiniest change--a random mutation or an ancient butterfly sneeze--caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary freaks? And what does that say about life on other planets?Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be.Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

    In the words of Edward O. Wilson, the museum stands as both "cabinet of wonder and temple of science." Its rich and unlikely history involves literary figures, creationists, millionaires, and visionary scientists from Asa Gray to Stephen Jay Gould. Its mastodon skeleton -- still on display -- is even linked to one of the nineteenth century's most bizarre and notorious murders. The Rarest of the Rare tells the fascinating stories behind the extinct butterflies, rare birds, lost plants, dazzling meteorites, and other scientific and historic specimens that fill the museum's halls. You'll learn about the painting that catches Audubon in a shameful lie, the sand dollar collected by Darwin during the voyage of the Beagle, and dozens of other treasures in this surprising, informative, and often amusing tour of the natural world.

    Using her own adoration of birds as a starting point to explore avian minutiae both strange and fascinating, Blaise winds through the interconnectedness between humans and our feathered friends, from the eccentric people who obsess about birds to the compelling ways people have integrated birds into culture throughout history, as well as our similar behaviors, kindred intelligence, and shared habitats.Thoughtful, philosophical, and delightful, Crazy for Birds pairs beautiful artwork with whimsical writing to explore the many wonders of birds, shedding light on our abiding connection with nature, the diversity of life, and the idiosyncrasy of the human psyche.

    Science and politics collide in this thrilling account of America's struggle for protection against the deadly threat of violent weather. Warnings tells the dramatic true stories of the unsung weather warriors who save innocent lives, often by risking their own.

    In California, the family camps in the brutally hot Mojave, where MacDonald hopes to see a rare desert tortoise. And in Churchill, Manitoba, he seeks out the dwindling polar bears—and meets them at a closer proximity than he had imagined.Along the way, MacDonald offers fascinating details about the natural history of the endangered species he seeks, as well as threats like overpopulation, commercial fishing, and climate change that are driving them towards extinction.

    Thanks to cartoons and folk accounts we have a distorted view of these other humans - for that is what they were. We think of them as crude and clumsy and not very bright, easily driven to extinction by the lithe, smart modern humans that came out of Africa some 100,000 years ago.But was it really as simple as that? Clive Finlayson reminds us that the Neanderthals were another kind of human, and their culture was not so very different from that of our own ancestors. In this book, he presents a wider view of the events that led to the migration of the moderns into Europe, what might have happened during the contact of the two populations, and what finally drove the Neanderthals to extinction. It is a view that considers climate, ecology, and migrations of populations, as well as culture and interaction.His conclusion is that the destiny of the Neanderthals and the Moderns was sealed by ecological factors and contingencies. It was a matter of luck that we survived and spread while the Neanderthals dwindled and perished. Had the climate not changed in our favour some 50 million years ago, things would have been very different.There is much current research interest in Neanderthals, much of it driven by attempts to map some of their DNA. But it's not just a question of studying the DNA. The rise and fall of populations is profoundly moulded by the larger scale forces of climate and ecology. And it is only by taking this wider view that we can fully understand the course of events that led to our survival and their demise. The fact that Neanderthals survived until virtually yesterday makes our relationship with them and their tragedy even more poignant. They almost made it, after all.

    We find animals and plants where we do because, over time, the continents have moved, separating and uniting in a long, slow dance; because sea levels have risen, cutting off one bit of land from another; because new and barren volcanic islands have risen up from the sea; and because animals and plants vary greatly in their ability to travel, and separation causes the formation of new species. This is the story of how life has responded to, and has in turn altered, the ever-changing Earth. And it includes many fascinating tales--of pygmy mammoths and elephant birds and of radical ideas by bold young scientists.

    Against a backdrop of modern world history, he's lurked in the shadows of some of the world's remotest places in order to capture footage of the animal kingdom's finest: prides of lions, silverback gorillas, capuchin monkeys, brown bears, grey whales, penguins, mosquitoes - you name it he's filmed it.From journeys to the deepest depths of the Antarctic Ocean and the wide expanse of the Saharan deserts, to the peaks of the Himalayas and the wild forests of the Congo, Gavin's experiences describe much more than just the incredible array of animals he's filmed. He invites you to come inside the cameraman's hidden world and discover the hours spent patiently waiting for the protagonists to appear; the inevitable dangers in the wings and the challenges faced and overcome; and the heart-warming, life-affirming moments the cameras miss as well as capture.
