In 1803 the United States purchased Louisiana from France. This seemingly simple acquisition brought with it an enormous new territory as well as the country’s first large population of nonnaturalized Americans—Native Americans, African Americans, and Francophone residents. What would become of those people dominated national affairs in the years that followed. This book chronicles that contentious period from 1803 to 1821, years during which people proposed numerous visions of the future for Louisiana and the United States. The Louisiana Purchase proved to be the crucible of American nationhood, Peter Kastor argues. The incorporation of Louisiana was among the most important tasks for a generation of federal policymakers. It also transformed the way people defined what it meant to be an American.

The assassin's bullet misses, the Archduke's carriage moves forward, and a catastrophic war is avoided. So too with the history of life. Re-run the tape of life, as Stephen J. Gould claimed, and the outcome must be entirely different: an alien world, without humans and maybe not even intelligence. The history of life is littered with accidents: any twist or turn may lead to a completely different world. Now this view is being challenged. Simon Conway Morris explores the evidence demonstrating life's almost eerie ability to navigate to a single solution, repeatedly. Eyes, brains, tools, even culture: all are very much on the cards. So if these are all evolutionary inevitabilities, where are our counterparts across the galaxy? The tape of life can only run on a suitable planet, and it seems that such Earth-like planets may be much rarer than hoped. Inevitable humans, yes, but in a lonely Universe.

"[An] extraordinary book. . . . Mr. Gould is an exceptional combination of scientist and science writer. . . . He is thus exceptionally well placed to tell these stories, and he tells them with fervor and intelligence."—James Gleick, New York Times Book Review High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It hold the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

Since its discovery in 1909 by Charles Doolittle Walcott, then Secretary of the Smithsonian Institution, the Burgess Shale in the Canadian Rocky Mountains has fascinated both scientists and the public with its plethora of weird wonders - life forms of the past so unfamiliar they cannot easily be assigned to known taxonomic groups. This century's most significant invertebrate fossil discovery, the Burgess Shale provides an unprecedented window into the explosive evolution during the Cambrian period that began about 540 million years ago, one of the most enigmatic episodes in the history of life. This book provides the first comprehensive set of illustrations of the extraordinary life forms revealed in the Burgess Shale. In addition to the more common fossilized hard skeletons, the Burgess Shale preserved the soft parts of these organisms, which provide a key to understanding the early evolution of the major groups of animals that inhabit the earth today. The Fossils of the Burgess Shale shows much remarkable detail - including digestive tracts and other internal organs - of creatures preserved in particles of mud fine enough to penetrate every crack and unevenness. The book begins with the history of exploration and research in the Burgess Shale, the geologic setting and preservation of the fossils, and a discussion of the Cambrian radiation, the period when almost all the major phyla of animals evolved. These introductory chapters are followed by 199 high-quality photographs and line drawings with detailed species accounts that describe important features of each specimen, as well as the ecology and taxonomy of each group. A complete list of all currently accepted species described from the Burgess Shale and a comprehensive bibliography follow the illustrations. The Fossil of the Burgess Shale is a compendium of fascinating Cambrian treasures that offer a rare glimpse into the nature of early life on our planet. They have figured prominently in recent evolutionary debates. The National Museum of Natural History, which houses more than 65,000 fossils collected by Walcott from the Burgess Shale, will open a new exhibition of the specimens in 1995.

Little is known about sixth-century Arabia. Yet from this distant time and place emerged a faith and an empire that stretched from Iberia to India. G. W. Bowersock illuminates this obscure yet most dynamic period in Islam, exploring why arid Arabia proved to be fertile ground for Muhammad’s message and why it spread so quickly to the wider world.

How did human beings acquire imaginations that can conjure up untrue possibilities? How did the Universe become self-aware? In The Runes of Evolution, Simon Conway Morris revitalizes the study of evolution from the perspective of convergence, providing us with compelling new evidence to support the mounting scientific view that the history of life is far more predictable than once thought. A leading evolutionary biologist at the University of Cambridge, Conway Morris came into international prominence for his work on the Cambrian explosion (especially fossils of the Burgess Shale) and evolutionary convergence, which is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. In The Runes of Evolution, he illustrates how the ubiquity of convergence hints at an underlying framework whereby many outcomes, not least brains and intelligence, are virtually guaranteed on any Earth-like planet. Conway Morris also emphasizes how much of the complexity of advanced biological systems is inherent in microbial forms. By casting a wider net, The Runes of Evolution explores many neglected evolutionary questions. Some are remarkably general. Why, for example, are convergences such as parasitism, carnivory, and nitrogen fixation in plants concentrated in particular taxonomic hot spots? Why do certain groups have a particular propensity to evolve toward particular states? Some questions lead to unexpected evolutionary insights: If bees sleep (as they do), do they dream? Why is that insect copulating with an orchid? Why have sponges evolved a system of fiber optics? What do mantis shrimps and submarines have in common? If dinosaurs had not gone extinct what would have happened next? Will a saber-toothed cat ever re-evolve? Cona Morris observes: “Even amongst the mammals, let alone the entire tree of life, humans represent one minute twig of a vast (and largely fossilized) arborescence. Every living species is a linear descendant of an immense string of now-vanished ancestors, but evolution itself is the very reverse of linear. Rather it is endlessly exploratory, probing the vast spaces of biological hyperspace. Indeed this book is a celebration of how our world is (and was) populated by a riot of forms, a coruscating tapestry of life.” The Runes of Evolution is the most definitive synthesis of evolutionary convergence to be published to date.

They were the Finest Creations - mystically forged creatures of perfection sent by the creators to aid the Fallen (mankind) during their mortal existence. Though they resemble ordinary horses they are highly intelligent, capable of communicating telepathically and completely moral. They are assigned to bond with individuals of great potential and then protect them from harm while guiding them along a path of virtue. This is as it has been for years unto creation ... but when a young Finest is separated from its mentor before it has been invested with its assignment, the result of an ambush by evil forces bent on corrupting men, the young equine accepts the charge of two orphans to its care not realizing that man's potential may rest in their future.... And that the path forward is already being diverted by an evil mastermind whose manipulation of court politics and affairs of state might instigate a new dark age upon the light of civilization.
