Download or read book Deep Time written by Gregory Benford and published by Harper Collins. This book was released on 2000-11-21 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining the logical rigor with the lyrical finesse of a novelist, award-winning author Gregory Benford explores these and other fascinating questions in this provocative analysis of humanity's attempts to make its culture immortal. In "Deep Time" he confronts our growing influence on events hundreds of thousands of years into the future and explores the possible "messeges" we may transmit to our distant descendants in the language of the planet itself, from nuclear waste to global warming to the extinction of species. As we begin our incredible journey down the path of eternity, Gregory Benford masterfully calls forth some of the intriguing, astounding, undreamed-of futures which may await us in deep time.

Download or read book Life in Deep Time written by J. William Schopf and published by CRC Press. This book was released on 2018-11-05 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Darwin wrote his Origin of Species, one of his main concerns was with the perceived shortness of the fossil record of life. Until the work of J. William Schopf and his colleagues, much of this history was thought to be unknowable. This book, through a memoire of Schopf’s personal recollections, documents astonishing discoveries revealing the first 85% of the history of life. These earliest periods of life on Earth emerge as a tale of individual and internationally collaborative exploration told by a scholar whose 60 years of research contributed to the recognition of the richness and diversity which forms the foundation of today’s biodiversity. Key Features Documents, through personal narrative, a paradigm shift is the study of the earliest life Summarizes a fossil record largely unknown until relatively recently Addresses one of Darwin's most troubling concerns about his theory of natural selection Predicts future developments in the study of first life

Download or read book Embryos in Deep Time written by Marcelo Sánchez-Villagra and published by Univ of California Press. This book was released on 2012-04-03 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can we bring together the study of genes, embryos and fossils? Embryos in Deep Time is a critical synthesis of the study of individual development in fossils. It brings together an up-to-date review of concepts from comparative anatomy, ecology and developmental genetics, and examples of different kinds of animals from diverse geological epochs and geographic areas. Can fossil embryos demonstrate evolutionary changes in reproductive modes? How have changes in ocean chemistry in the past affected the development of marine organisms? What can the microstructure of fossil bone and teeth reveal about maturation time, longevity and changes in growth phases? This book addresses these and other issues and documents with numerous examples and illustrations how fossils provide evidence not only of adult anatomy but also of the life history of individuals at different growth stages. The central topic of Biology today—the transformations occurring during the life of an organism and the mechanisms behind them—is addressed in an integrative manner for extinct animals.

Download or read book Islands in Deep Time written by Markes E. Johnson and published by Columbia University Press. This book was released on 2023-10-31 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hilltops surrounded by farmland in southern Wisconsin turn out to be the eroded remnants of an ancient archipelago. An island in the Yellow Sea where Korean tourists flock is the peak of a flooded mountain rising from a drowned continental shelf. From a mountaintop shrine to Genghis Khan in Inner Mongolia, the silhouette of a Silurian seascape can be spotted. On the shores of Hudson Bay, where polar bears patrol the Arctic tundra, a close look unveils what was a tropical coastline encrusted with corals nearly 450 million years ago. The geologist Markes E. Johnson invites readers on a journey through deep time to find the traces of ancient islands. He visits a dozen sites around the globe, looking above and below today’s waterlines to uncover how landscapes of the past are preserved in the present. Going back 500 million years to the Cambrian through the Pleistocene 125,000 years ago, this book reconstructs how “paleoislands” appeared under different climatic conditions and environmental constraints. Finding vestiges of prehistoric ecologies, Johnson emphasizes the complexity of island ecosystems and the importance of preserving these significant sites. Inviting and accessible, this book is a travelogue that takes readers through time as well as space. Islands in Deep Time shares the adventure of exploring striking locations across geologic eras and issues a passionate call for their conservation.

Download or read book Digressions in Deep Time written by Declan Lloyd and published by Rowman & Littlefield. This book was released on 2024-06-18 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Deep time” is a term which attempts to capture temporal scales far beyond human comprehension. These are stretches of time epitomised by geological and cosmic scale processes, vast enough to make the entirety of human existence appear as little more than a footnote. The past few years have seen a boom in texts dedicated to the study of deep time, extending across a broad range of disciplines which fall markedly outside of its geological roots. These studies are unified by two ideas in particular: that deep time thinking and ecocriticism should be considered in conjunction, and that literature and the arts play a vital role in fostering a deep time awareness. Digressions in Deep Time is the first collection of essays which considers the multifarious representations of deep time across literature and the arts, assembling the work of a wide range of prominent scholars whose research frequently engages with temporality and ecocriticism. Featured contributions include work by the Pulitzer-prize winning author John McPhee, who popularised the term deep time in the late seventies, as well as chapters by Richard Irvine (author of An Anthropology of Deep Time), Benjamin Morgan (author of The Outward Mind) and Andrew Tate (author of Apocalyptic Fiction).

Book excerpt: National Bestseller • New York Times "100 Notable Books of the Year" • NPR "Favorite Books of 2019" • Guardian "100 Best Books of the 21st Century" • Winner of the National Outdoor Book Award "Mesmerizing…Underland is a portal of light in dark times." —Terry Tempest Williams, New York Times Book Review In Underland, Robert Macfarlane delivers an epic exploration of the Earth’s underworlds as they exist in myth, literature, memory, and the land itself. Traveling through the dizzying expanse of geologic time—from prehistoric art in Norwegian sea caves, to the blue depths of the Greenland ice cap, to a deep-sunk "hiding place" where nuclear waste will be stored for 100,000 years to come—Underland takes us on an extraordinary journey into our relationship with darkness, burial, and what lies beneath the surface of both place and mind. Global in its geography and written with great lyricism, Underland speaks powerfully to our present moment. At once ancient and urgent, this is a book that will change the way you see the world.
