They made the world theirs long before the rise of dinosaurs. Travelling forward into the Permian and then Triassic periods, we learn how our ancient mammal ancestors evolved from large hairy beasts with accelerating metabolisms to exploit miniaturisation, which was key to unlocking the traits that define mammals as we now know them. Elsa criss-crosses the globe to explore the sites where discoveries are being made and meet the people who make them. In Scotland, she traverses the desert dunes of prehistoric Moray, where quarry workers unearthed the footprints of Permian creatures from before the time of dinosaurs. In South Africa, she introduces us to animals, once called 'mammal-like reptiles', that gave scientists the first hints that our furry kin evolved from a lineage of egg-laying burrowers. In China, new, complete fossilised skeletons reveal mammals that were gliders, shovel-pawed Jurassic moles, and flat-tailed swimmers.This book radically reframes the narrative of our mammalian ancestors and provides a counterpoint to the stereotypes of mighty dinosaur overlords and cowering little mammals. It turns out the earliest mammals weren't just precursors, they were pioneers.

    How is it possible that the Y chromosome, which separated the sexes and allowed humans to rise to the apex of the animal kingdom, also threatens to destroy sexual reproduction altogether? Bryan Sykes confronts recent advances in evolutionary theory to find the answers to the questions that inexorably follow: Is there a genetic cause for men's greed, aggression, and promiscuity? Could a male homosexual gene possibly exist? A must read for anyone interested in popular science, family genealogy, and today's infertility crisis, "Adam's Curse" provokes a shocking debate on the nature of sexual reproduction.

    Could such an apparently impotent and mindless force really have built the sophisticated molecular devices found throughout nature? The answer, he insists, is no. The only common-sense explanation is intelligent design

    Alexander von Humboldt (1769 – 1859) was an intrepid explorer and the most famous scientist of his age. In North America, his name still graces four counties, thirteen towns, a river, parks, bays, lakes, and mountains. His restless life was packed with adventure and discovery, whether he was climbing the highest volcanoes in the world or racing through anthrax-infected Siberia or translating his research into bestselling publications that changed science and thinking. Among Humboldt's most revolutionary ideas was a radical vision of nature, that it is a complex and interconnected global force that does not exist for the use of humankind alone. Now Andrea Wulf brings the man and his achievements back into focus: his daring expeditions and investigation of wild environments around the world and his discoveries of similarities between climate and vegetation zones on different continents. She also discusses his prediction of human-induced climate change, his remarkable ability to fashion poetic narrative out of scientific observation, and his relationships with iconic figures such as Simón Bolívar and Thomas Jefferson. Wulf examines how Humboldt's writings inspired other naturalists and poets such as Darwin, Wordsworth, and Goethe, and she makes the compelling case that it was Humboldt's influence that led John Muir to his ideas of natural preservation and that shaped Thoreau's Walden.With this brilliantly researched and compellingly written book, Andrea Wulf shows the myriad fundamental ways in which Humboldt created our understanding of the natural world, and she champions a renewed interest in this vital and lost player in environmental history and science.

    Drawing on the new field of neuroeconomics, Shermer investigates what brain scans reveal about bargaining, snap purchases, and establishing trust in business. He scrutinizes experiments in behavioral economics to understand why people hang on to losing stocks, why negotiations disintegrate into tit-for-tat disputes, and why money does not make us happy. He brings together astonishing findings from psychology, biology, and other sciences to describe how our tribal ancestry makes us suckers for brands, why researchers believe cooperation unleashes biochemicals similar to those released during sex, why free trade promises to build alliances between nations, and how even capuchin monkeys get indignant if they don't get a fair reward for their work.

    The prairies are the heartland of the continent, a vast, windswept plain that flows from Alberta south to Texas and from the Rockies east to the Mississippi River. This is big sky country, and until recently, one of the richest and most magnificent natural grasslands in the world. Today, however, the North American prairies are among the most altered environments on Earth. Thorough, detailed, and scientifically up-to-date, Prairie: A Natural History provides a comprehensive, nontechnical guide to the biology and ecology of this fabled environment, offering a view of the past, a vision for the future, and a clear focus on the present. Sidebars throughout highlight various grasslands species, tell fascinating natural history and conservation stories, and present the traditional Native American view of the prairie and its inhabitants.

    Situating these fascinating animals in a broad ecological and evolutionary context, leading dinosaur expert Scott D. Sampson fills us in on the exhilarating discoveries of the past twenty-five years, the most active period in the history of dinosaur paleontology, during which more “new” species were named than in all prior history. With these discoveries—and the most recent controversies—in mind, Sampson reconstructs the odyssey of the dinosaurs from their humble origins on the supercontinent Pangaea, to their reign as the largest animals the planet has ever known, and finally to their abrupt demise. Much more than the story of who ate whom way back when, Dinosaur Odyssey places dinosaurs in an expansive web of relationships with other organisms and demonstrates how they provide a powerful lens through which to observe the entire natural world. Addressing topics such as extinction, global warming, and energy flow, Dinosaur Odyssey finds that the dinosaurs' story is, in fact, a major chapter in our own story.

    It is part journey, part history, and it concludes with awkward questions about the future of Britain's landscapes. Nick Crane's story begins with the melting tongues of glaciers and the emergence of a gigantic game-park tentatively being explored by a vanguard of Mesolithic adventurers who have taken the long, northward hike across the land bridge from the continent. The Iron Age develops into a pre-Roman 'Golden Era' and Nick Crane looks at what the Romans did (and didn't) contribute to the British landscape. Major landscape 'events' (Black Death, enclosures, urbanisation, recreation, etc.) are fully described and explored, and he weaves in the role played by geology in shaping our cities, industry and recreation, the effect of climate (and the Gulf Stream), and of global economics (the Lancashire valleys were formed by overseas markets). The co-presenter of BBC's Coast also covers the extraordinary benefits bestowed by a 6,000-mile coastline. The 10,000-year story of the British landscape culminates in the 21st century, which is set to be one of the most extreme centuries of change since the Ice Age.Nick Crane brilliantly illustrates how Britain and its landscapes became so wonderfully diverse.

    But they are relative newcomers there. They evolved in North America and retain their greatest diversity in South America, while the only wild dromedaries are in Australia.This is a classic example of the contradictions of 'native' and 'invasive' species, a hot issue right now as the flip-side of biodiversity. Do we need to fear invaders? Can we control them? Do we choose the right targets? And are the natives always good guys?Thompson puts forward a fascinating array of narratives to explore this crucial question.

    Already there have been five mass extinctions in the last 600 million years, including the Cretaceous Extinction, during which an asteroid knocked out the dinosaurs. Though these events were initially destructive, they were also prime movers of evolutionary change in nature. And we can see some of the warning signs of another extinction event coming, as our oceans lose both fish and oxygen. In The Next Species, Michael Tennesen questions what life might be like after it happens.Tennesen discusses the future of nature and whether humans will make it through the bottleneck of extinction. Without man, could the seas regenerate to what they were before fishing vessels? Could life suddenly get very big as it did before the arrival of humans? And what if man survives the coming catastrophes, but in reduced populations? Would those groups be isolated enough to become distinct species? Could the conquest of Mars lead to another form of human? Could we upload our minds into a computer and live in a virtual reality? Or could genetic engineering create a more intelligent and long-lived creature that might shun the rest of us? And how would we recognize the next humans? Are they with us now?Tennesen delves into the history of the planet and travels to rainforests, canyons, craters, and caves all over the world to explore the potential winners and losers of the next era of evolution. His predictions, based on reports and interviews with top scientists, have vital implications for life on earth today.
