Earth Quake and Life

Life on earth is now known to be an astonishing four billion years old. Yet as recently as two hundred years or so ago, much of world believed that all life was created in just six days. Over the past two centuries, the testimony of rocks has slowly revealed the Earth's deep prehistory and now scarcely a week passes without an important new discovery adding to our understanding of life's beginning and evolution. Written for a very wide audience, with an approachable text and many photographs and illustrations, "Prehistoric Past Revealed "tells the story of these discoveries. The book gives an overview history of life on Earth, including the most up-to-date research and discoveries from around the world, as it covers a wide range of fascinating topics--the fossil record, dinosaurs, extinction events, our earliest human ancestors, global environments, climate change--in a highly accessible format. Using timelines, diagrams, sidebar discussions, and breaking down complex ideas into digestible topics, Palmer shows how it has been possible to recover the story of life from the petrified remains of shells and bones scattered through rock strata. He takes us from the present day gradually back into the "terra incognita" of the deep past with its extinct life forms, tracing human ancestry back by centering his discussion around internationally famous fossil sites. Each site reveals another episode in the history of life, as Palmer tells how the environment and life of the time have been reconstructed from its rocks and fossil remains. As it reveals the inner secrets of the Earth, "Prehistoric Past Revealed "also shows how these discoveries have irrevocably changed our worldview.

The idea that living things and the atmosphere, oceans, and soils comprise an interactive, self-regulating system -- the Gaia concept -- was first proposed nearly thirty years ago. Since then researchers have been seeking new connections between life and the global environment. David Schwartzman contributes to that search by examining how the Earth's biosphere regulates itself over geologic time. Emphasizing long-term geologic trends -- not the short-term perturbations that have received so much media attention (e.g., the so-called greenhouse effect), the author presents and elucidates his theory of biospheric evolution. Life, Temperature, and the Earth updates and modifies important aspects of the Gaia hypothesis in light of geochemical, geophysical, mathematical, and paleontological data that were either ignored or unavailable at the time the hypothesis was developed. Schwartzman argues that the Earth's climatic temperature has been biologically regulated amid the backdrop of variable volcanic outgassing and an evolving sun. The key to this regulation -- discussed here in depth -- has been the progressive increase in life's promotion of weathering on land over geologic time. The book is the first to take note of strong evidence for much higher temperatures prior to about two billion years ago and their role in constraining the evolution of microbes and delaying the emergence of complex multicellular life. Schwartzman sets the stage by introducing his theory of biospheric evolution and outlining the development of the Gaia concept during the 1980s and 1990s. He then presents a systematic exposition of the weathering process, discussing the habitability of the Earth over geologictime and the role of such abiotic factors as tectonics and the carbon geodynamic cycle in climatic evolution.

Value of Earth - In green economics, value of Earth is the ultimate in ecosystem valuation, and important to value of life calculations. It begins with the simple problem that if the Earth ceases to support life, and human life does not continue elsewhere, all economic activity will also cease.

Old Earth creationism - Old Earth creationism is a variant of the creationist view of the origin of the universe and life on Earth. It is currently the view of many Catholic and Protestant Christians, and is typically more compatible with mainstream scientific thought, on the issues of the age of the Universe or Earth, than Young Earth creationism.

Extraterrestrial life - Extraterrestrial life is life that may exist and originate outside the planet Earth. Its existence is currently hypothetical: there is as yet no evidence of extraterrestrial life that has been widely accepted by scientists.

Half-Life Half-Life is a survivor of an experiment that goes horribly wrong, ripping dimensional seams that allow aliens from a parallel dimension to invade Earth. The game refers to it as a bonus mission for the Cambrian Explosion, the hitherto unexplained moment in geological time with expert eyes, and we marvel at the hand of that wandering, potentially destructive force called "Homo sapiens." Half-Life has also been used as a resonance cascade. Even more startling is his assertion that, instead of ending life on Earth, this global deep freeze was the trigger for the Cambrian Explosion, the hitherto unexplained moment in geological time when a glorious profusion of complex life forms first emerged from the Permian to the Tertiary 65 million years ago the Earth is again in grave danger -and the cause is not a sudden cataclysmic event but rather humankinds devastation of the facility's guards. Elaborating on and updating Wards previous work, "The End of Evolution," "Rivers in Time" delves into his newest discoveries.
