Tome was born in 1782 near present-day Harrisburg and lived on the upper Susquehanna for much of his life. He tells colorful (and mostly true) tales about his hunting exploits in the Pennsylvania wilderness, as he tracked elk, wolves, bears, panthers, foxes, and other large animals through the state’s north-central mountains, earning wide renown among his contemporaries. His stories contain suspenseful chase scenes, accidents, and narrow escapes, inviting the reader to view a still-wild Pennsylvania through the eyes of one who “was never conquered by man or animal.” Pioneer Life, originally published in 1854, has since been reprinted several times. This classic hunting memoir includes the following chapters: I. Birth and Early Life II. Hunting the Elk III. Capturing a Live Elk IV. Face of the Country V. Face of the Country — Continued VI. Danger From Rattlesnakes VII. Wolf and Bear Hunting VIII. Another Elk Hunt IX. Elk-Hunting on the Susquehannah X. Elk-Hunting — Continued XI. Nature, Habits, and Manner of Hunting the Elk XII. Elk and Bear Hunting in Winter XIII. Hunting on the Clarion River XIV. Hunting and Trapping XV. The Bear, Its Nature and Habits XVI. Hunting Deer at Different Seasons XVII. Nature and Habits of the Panther, Wolf and Fox XVIII. Rattlesnakes and Their Habits XIX. Distinguished Lumbermen, Etc. XX.. Reminiscences of Cornplanter XXI. Indian Eloquence This book originally published in 1854 has been reformatted for the Kindle and may contain an occasional defect from the original publication or from the reformatting

    With the help of a beguiling mix of illustrated optical illusions and puzzles, anecdotes, mathematics, and philosophy, Ings reveals age-old mysteries from how humans perceive color to Woody Allen's ability to raise the inner corners of his eyebrows." A Natural History of Seeing delves into both the evolution of sight and the evolution of our understanding of sight. It gives us the natural science - the physics of light and the biology of animals and humans alike - while also addressing Leonardo da Vinci's theories of perception in painting and Homer's confused and strangely limited sense of color. Panoramic in every sense, it reaches back to the first seers (and to ancient beliefs that vision is the product of mysterious optic rays) and forward to the promise of modern experiments in making robots that see.

    The aim remains to provide a reference to the aspects of medical microbiology particularly important for clinical infections and chemotherapy. Geo. F. Brooks (U. of California, San Francisco), Jane

    The authors introduce the general reader to some of the most important basic findings, concepts, and procedures of evolutionary biology, as it has developed since the first publications of Darwin and Wallace on the subject, over 140 years ago. They show how evolution provides a unifying set of principles for the whole of biology and sheds light on the relation of human beings to the universe and each other.

    It sparked a national debate on evolution, which continues to intensify across the country. From one end of the spectrum to the other, Darwin's Black Box has established itself as the key intelligent design text -- the one argument that must be addressed in order to determine whether Darwinian evolution is sufficient to explain life as we know it.In a major new Afterword for this edition, Behe explains that the complexity discovered by microbiologists has dramatically increased since the book was first published. That complexity is a continuing challenge to Darwinism, and evolutionists have had no success at explaining it. Darwin's Black Box is more important today than ever.

    The well-structured pedagogical framework of the text, with its emphasis on overarching ideas, makes the material accessible to introductory students.

    Cave paintings of the giant beasts hint at the profound role they played in early human culture-our Ice Age ancestors built igloo-shaped huts out of mammoth bones and even feasted on mammoth tongues. Eager to uncover more clues to this mystical prehistoric age, explorers since the time of Peter the Great have scoured Siberia for mammoth remains. Now a new generation of explorers has taken to the tundra. Armed with GPS, ground-penetrating radar, and Soviet-era military helicopters, they seek an elusive prize: a mammoth carcass that will help determine how the creature lived, how it died-and how it might be brought back to life.In this adventure-filled narrative, science writer Richard Stone follows two teams of explorers-one Russian/Japanese, the other a French-led consortium-as they battle bitter cold, high winds, supply shortages, and the deeply rooted superstitions of indigenous peoples who fear the consequences of awakening the "rat beneath the ice." Stone travels from St. Petersburg to the Arctic Circle, from the North Sea to high-tech Japanese laboratories, as he traces the sometimes-surreal quest of these intrepid scientists, whose work could well rewrite our planet's evolutionary history. A riveting tale of high-stakes adventure and scientific hubris, Mammoth is also an intellectual voyage through uncharted moral terrain, as we confront the promise and peril of resurrecting creatures from the deep past.

    The majority view is that life began with replicating molecules, the precursors of modern genes. The minority belief is that random populations of molecules evolved metabolic activities before exact replication existed and that natural selection drove the evolution of cells toward greater complexity for a long time without the benefit of genes. Dyson analyzes both of these theories with reference to recent important discoveries by geologists and chemists, aiming to stimulate new experiments that could help decide which theory is correct. This second edition covers the impact revolutionary discoveries such as the existence of ribozymes, enzymes made of RNA; the likelihood that many of the most ancient creatures are thermophilic, living in hot environments; and evidence of life in the most ancient of all terrestrial rocks in Greenland have had on our ideas about how life began. It is a clearly written, fascinating book that will appeal to anyone interested in the origins of life.

    Two days later, she got her first glimpse of the famous, terrifying jaws up close and she was instantly hooked; her fascination soon yielded to obsession-and an invitation to return for a full season. But as Casey readied herself for the eight-week stint, she had no way of preparing for what she would find among the dangerous, forgotten islands that have banished every campaign for civilization in the past two hundred years.

    For millions, the Galápagos Islands represent nature at its most unspoiled, an inviolate place famed for its rare flora and fauna. But soon today’s 30,000 human residents could surpass 50,000. Add invasive species, floods of tourists, and unresolved conflicts between Ecuadorian laws and local concerns, and it’s easy to see why the Galápagos were recently added to UNESCO’s World Heritage in Danger list. Each chapter in this provocative, perceptive book focuses on a specific person or group with a stake in the Galápagos’ natural resources—from tour companies whose activities are often illegal and not always green, to creationist guides who lead tours with no mention of evolution, from fishermen up in arms over lobster quotas, to modern-day pirates who poach endangered marine species. Bassett presents a perspective as readable as it is sensible. Told with wit, passion, and grace, the Galápagos story serves as a miniature model of Earth itself, a perfect example of how an environment can be destroyed-- and what is being done to preserve these islands before it's too late.

    In many countries, supplies of food and water are inadequate to support the population, so the world falls deeper and deeper into what economists call the "Malthusian trap."Here, Malthus examines the tendency of human numbers to outstrip their resources, and argues that poverty, disease, and starvation are necessary to keep societies from moving beyond their means of subsistence.Public Domain (P)2013 Audible Ltd

    In Tales from the Underground, Cornell ecologist David Wolfe takes us on a tour through current scientific knowledge of the subterranean world. We follow the progress of discovery from Charles Darwin's experiments with earthworms, to Lewis and Clark's first encounter with prairie dogs, to the use of new genetic tools that are revealing an astonishingly rich ecosystem beneath our feet. Wolfe plunges us deep into the earth's rocky crust, where life may have begun-a world devoid of oxygen and light but safe from asteroid bombardment. Primitive microbes found there are turning our notion of the evolutionary tree of life on its head: amazingly, they represent perhaps a full third of earth's genetic diversity. As Wolfe explains, creatures of the soil can work for us, by providing important pharmaceuticals and recycling the essential elements of life, or against us, by spreading disease and contributing to global climate change. The future of our species may well depend on how we manage our living soil resources. Tales from the Underground will forever alter our appreciation of the natural world around-and beneath-us.
