In this thrill-ride across millennia and continents, the complete history of the planet comes to life: from the Earth's fiery birth to its near-obliteration in the Triassic period, and from the first signs of human life to the tentative future of a world with a burgeoning population and a global warming crisis. Covering a wide range of topics including astrophysics, zoology, and sociology, and complete with maps and illustrations, What on Earth Happened? In Brief is the endlessly entertaining story of the planet, life, and people.

    A team of fossil hunters... A desperate fight to survive.... In book 5, Hannah and the other survivors arrive in the ice world of the Pleistocene, bare of trees and with almost no animal life. Starving, with no other game to hunt, they must take on the mighty Mammoth and his wicked tusks. Can they survive the freeze long enough to jump back to modern times?

    He did not mean to rock the world. He meant only to know the truth. But before he was done, Charles Darwin would shake the faith of centuries...would be reviled as a fiend, denounced as a madman - and finally hailed as a genius. His life was a storm-swept voyage of discovery-from the moment when as a raw youth he set sail on a five-year journey around the entire globe to his final years and epochal explorations into the ultimate mystery of human origins. Now Charles Darwin is brought to life in a superlative novel that captures not only the man himself but the Victorian age that produced him. These pages reveal the drama and passion of a beset by the prejudices of his era and by guessed-at dangers.

    If these galaxies had always been travelling, he reasoned, then they must, at some point, have been on top of one another. This discovery transformed the debate about one of the most fundamental questions of human existence - how did the universe begin?Every society has stories about the origin of the cosmos and its inhabitants, but now, with the power to peer into the early universe and deploy the knowledge gleaned from archaeology, geology, evolutionary biology and cosmology, we are closer than ever to understanding where it all came from. In The Origin of (almost) Everything, New Scientist explores the modern origin stories of everything from the Big Bang, meteorites and dark energy, to dinosaurs, civilisation, timekeeping, belly-button fluff and beyond.From how complex life evolved on Earth, to the first written language, to how humans conquered space, The Origin of (almost) Everything offers a unique history of the past, present and future of our universe.span

    Conway Morris is one of the few paleontologists ever to explore the Burgess Shale, having been involved in the dig since 1972, and thus he is an ideal guide to this amazing discovery. Indeed, he provides a complete overview of this remarkable find, ranging from an informative, basic discussion of the origins of life and animals on earth, to a colorful description of Charles Walcott's discovery of the Burgess Shale and of the painstaking scientific work that went on there (as well as in Burgess collections held at Harvard and the Smithsonian), to an account of similar fossil finds in Greenland and in China. The heart of the book is an imaginative trip in a time machine, back to the Cambrian seas, where the reader sees first-hand the remarkable diversity of life as it existed then. And perhaps most important, Conway Morris examines the lessons to be learned from the Burgess Shale, especially as they apply to modern evolutionary thinking. In particular, he critiques the ideas of Stephen Jay Gould, whose best-selling book Wonderful Life drew on Conway Morris's Burgess Shale work. The author takes a fresh look at the evidence and draws quite different conclusions from Gould on the nature of evolution. This finely illustrated volume takes the reader to the forefront of paleontology as it provides fresh insights into the nature of evolution and of life on earth.

    That word is formication, and the implied sense of horror and fascination, contends Richard Conniff, is something many of us actually crave. His Spineless Wonders presents an unabashed wallow in the joy of formication. Spineless Wonders is an engaging, sophisticated, and humorous mix of natural history and human lore. Through his journalistic assignments, Richard Conniff has been in contact with invertebrates for more than twenty years - tarantulas in the upper Amazon region, dragonflies in Arizona, squid in Florida, and flies on the rim of his beer glass. Discoveries about the extraordinary habits and idiosyncrasies of the moth, the leech, the ant, and the slime eel are opening new frontiers in the exploration of our natural universe. Spineless Wonders takes us directly to these wild and wonderful outposts to observe the hazards of being around invertebrates, the bizarre adaptions that enable them to survive in the world, and also the astonishing work they do - work that enables us to survive.

     This book is a supplement to What If? and intended to enhance the experience of reading the original book. We recommend purchasing the full version of What If? on Amazon in addition to this book. Introduction What If? Serious Scientific Answers to Absurd Hypothetical Questions presents a wide variety of questions covering a range of dubious potentialities and the results which would ensue should they become reality. The questions are collected from author Randall Munroe’s website, where they are sent in by readers of his blog. Some of the questions are conceptual, for example how much force would be required for Yoda to lift an X-fighter, others are in a more serious vein. All of the answers however are based on research and the application of scientific principles by the author, himself trained in physics and a former roboticist for NASA.

    Inscribed runes spelled out a promise beyond belief. The Key To Paradise. A promise and a quest. Giles Grimsmate, world-wandering survivor of the Trans wars, had won it fairly in a game of chance. The second key - along with a goodly haul of coin - had been stolen from a rich merchant by Keja Tchurak, master thief. And when they set out for the invisible Gates of Paradise, Petia, half-cat, half-woman, tracked them with silent night-skills. Yet to enter Paradise, three keys more were needed: The Flame Key, watched over by a cave-dwelling fire sorceress. The Key of the Skeleton Lord, devil-guarded in a desert place of scorpions and snakes. The Key of Ice and Steel, fast-locked in an underground smithy, protected by a frozen demon-prowled maze. Five keys, scattered throughout a realm of supernatural happenings, strange creatures and otherworldly powers:

    But things didn't turn out that way. For a start, we turned out to have far fewer genes than originally thought - just over 20,000, the same sort of number as a fruit fly or worm. What's more, the proportionof DNA consisting of genes coding for proteins was a mere 2%. So, was the rest of the genome accumulated 'junk'?Things have changed since those early heady days of the Human Genome Project. But the emerging picture is if anything far more exciting. In this book, John Parrington explains the key features that are coming to light - some, such as the results of the international ENCODE programme, still much debated and controversial in their scope. He gives an outline of the deeper genome, involving layers of regulatory elements controlling and coordinating the switching on and off of genes; the impact ofits 3D geometry; the discovery of a variety of new RNAs playing critical roles; the epigenetic changes influenced by the environment and life experiences that can make identical twins different and be passed on to the next generation; and the clues coming out of comparisons with the genomes ofNeanderthals as well as that of chimps about the development our species. We are learning more about ourselves, and about the genetic aspects of many diseases. But in its complexity, flexibility, and ability to respond to environmental cues, the human genome is proving to be far more subtle than we ever imagined.

    In 1966, simple Darwinism, which holds that evolution functions primarily at the level of the individual organism, was threatened by opposing concepts such as group selection, a popular idea stating that evolution acts to select entire species rather than individuals. George Williams's famous argument in favor of the Darwinists struck a powerful blow to those in opposing camps. His Adaptation and Natural Selection, now a classic of science literature, is a thorough and convincing essay in defense of Darwinism; its suggestions for developing effective principles for dealing with the evolution debate and its relevance to many fields outside biology ensure the timelessness of this critical work.

    Tedford have spent the past 20 years studying the evolutionary history of the family Canidae. Both are well known for having established the modern framework for the evolutionary relationship of canids. Combining their research with Mauricio Ant�n's impeccable reconstructions of both extinct and extant species, Wang and Tedford present a remarkably detailed and nuanced portrait of the origin and evolution of canids over the past 40 million years.The authors cull their history from the most recent scientific research conducted on the vast collections of the American Museum of Natural History and other leading institutions. The fossil record of the Canidae, particularly those from their birth place in North America, are the strongest of their kind among known groups of carnivorans. Such a wonderfully detailed evolutionary history provides access to a natural history that is not possible with many other groups of carnivorans.With their rich fossil record, diverse adaptations to various environments, and different predatory specializations, canids are an ideal model organism for the mapping of predator behavior and morphological specializations. They also offer an excellent contrast to felids, which remain entrenched in extreme predatory specializations. The innovative illustrated approach in this book is the perfect accompaniment to an extremely important branch of animal and fossil study. It transforms the science of paleontology into a thrilling visual experience and provides an unprecedented reference for anyone fascinated by dogs.

    Anderson. Working from Frank Herbert's own notes, the acclaimed authors reveal the chapter of the Dune saga most eagerly anticipated by readers: the Butlerian Jihad.Throughout the Dune novels, Frank Herbert frequently referred to the war in which humans wrested their freedom from "thinking machines." In Dune: The Butlerian Jihad, Brian Herbert and Kevin J. Anderson bring to life the story of that war, a tale previously seen only in tantalizing hints and clues. Finally, we see how Serena Butler's passionate grief ignites the struggle that will liberate humans from their machine masters; here is the amazing tale of the Zensunni Wanderers, who escape bondage to flee to the desert world where they will declare themselves the Free Men of Dune. And here is the backward, nearly forgotten planet of Arrakis, where traders have discovered the remarkable properties of the spice melange. . . . Dune: The Machine Crusade More than two decades have passed since the events chronicled in Dune: The Butlerian Jihad. The crusade against thinking robots has ground on for years, but the forces led by Serena Butler and Irbis Ginjo have made only slight gains; the human worlds grow weary of war, of the bloody, inconclusive swing from victory to defeat.The fearsome cymeks, led by Agamemnon, hatch new plots to regain their lost power from Omnius--as their numbers dwindle and time begins to run out. The fighters of Ginaz, led by Jool Noret, forge themselves into an elite warrior class, a weapon against the machine-dominated worlds. Aurelius Venport and Norma Cenva are on the verge of the most important discovery in human history-a way to "fold" space and travel instantaneously to any place in the galaxy.And on the faraway, nearly worthless planet of Arrakis, Selim Wormrider and his band of outlaws take the first steps to making themselves the feared fighters who will change the course of history: the Fremen.Here is the unrivaled imaginative power that has put Brian Herbert and Kevin Anderson on bestseller lists everywhere and earned them the high regard of readers around the globe. The fantastic saga of Dune continues in Dune: The Machine Crusade. Dune: The Battle of Corrin It has been fifty-six hard years since the events of Dune: The Machine Crusade. Following the death of Serena Butler, the bloodiest decades of the Jihad take place. Synchronized Worlds and Unallied Planets are liberated one by one, and at long last, after years of victory, the human worlds begin to hope that the end of the centuries-long conflict with the thinking machines is finally in sight.Unfortunately, Omnius has one last, deadly card to play. In a last-ditch effort to destroy humankind, virulent plagues are let loose throughout the galaxy, decimating the populations of whole planets . . . and once again, the tide of the titanic struggle shifts against the warriors of the human race. At last, the war that has lasted many lifetimes will be decided in the apocalyptic Battle of Corrin.In the greatest battle in science fiction history, human and machine face off one last time. . . . And on the desert planet of Arrakis, the legendary Fremen of Dune become the feared fighting force to be discovered by Paul Muad'Dib in Frank Herbert's classic, Dune.
