Available in PDF, EPUB and Kindle. Book excerpt: A fast ride through dizzying scientific extrapolations! When Paleontologist Karen Regan discovers a machine in 550 million year old rock, she is shocked to discover it appears intact. She calls on her former lover, Steve Ryle, to supply his revolutionary microscopic robots to explore the interior of the device. With the help of an engineer, Daltry, the three of them discover more than they dreamed possible: the machine not only is still active, but it has been waiting to deliver a terrible message — a message that cannot be heard, but must be experienced. A message that will transform each of them into something more — or less — than human. How these three explorers react to the gift of the Ediacaran machine will determine whether the human race survives or perishes. Praise for the “Ediacarian Machine” (which forms the first third of The Ediacaran Invasion, and was published in Analog Science Fiction) include: “A very classic skiffy scenario. It has robotics, alien wonders, mysteries to be solved, exploratory adventures, and cosmic scope. It has ethical issues to be worked out. No one is an idiot or a villain, even when they don’t agree. Fans should really like it. RECOMMENDED.” —Lois Tilton, writing in Locus ____________________ Short Novel 35,000 words DANGEROUS IDEAS In the spirit of The Twilight Zone and Golden Age Science Fiction, the Dangerous Ideas collection presents short novels of science fiction that explore the most extreme possibilities--and leave you in wonder.
Download or read book When the Invasion of Land Failed written by George R. McGhee, Jr. and published by Columbia University Press. This book was released on 2013-11-12 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: The invasion of land by ocean-dwelling plants and animals was one of the most revolutionary events in the evolution of life on Earth, yet the animal invasion almost failed—twice—because of the twin mass extinctions of the Late Devonian Epoch. Some 359 to 375 million years ago, these catastrophic events dealt our ancestors a blow that almost drove them back into the sea. If those extinctions had been just a bit more severe, spiders and insects might have become the ecologically dominant forms of animal life on land. This book examines the profound evolutionary consequences of the Late Devonian extinctions, which shaped the composition of the modern terrestrial ecosystem. Only one group of four-limbed vertebrates now live on Earth while other tetrapod-like fishes are extinct. This gap is why the idea of “fish with feet” seems so peculiar yet these animals were once a vital part of our world.

Download or read book The Rise and Fall of the Ediacaran Biota written by Patricia Vickers-Rich and published by Geological Society of London. This book was released on 2007 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Proterozoic and early Phanerozoic was a time punctuated by a series of significant events in Earth history. Glaciations of global scale wracked the planet, interfingered with dramatic changes in oceanic and atmospheric chemistry and marked changes in continental configuration. It was during these dynamic and 'weedy' times that metazoans first appeared, diversified, culminating in the appearance of hard tissue skeletons and deep 'farming' of the marine substrate, in late Proterozoic and first few millions of years of the Phanerozoic. This book is the culmination of two symposia of UNESCO International Geological Correlation Project 493, one in Prato (Italy) in 2004, the second in Kyoto (Japan) in 2006. Both dealt specifically with the precise timing of physical events and teasing out of the effects which these changing environments, climates, global chemistry and palaeogeography had on the development and diversification of animals, culminating in the spectacular Ediacaran/Vendian faunas of the late Precambrian.
Download or read book The Trace Fossil Record of Major Evolutionary Events written by M. Gabriela Mángano and published by Springer. This book was released on 2016-11-17 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses major evolutionary changes that took place during the Ediacaran and the Paleozoic. These include discussions on the nature of Ediacaran ecosystems, as well as the ichnologic signature of evolutionary radiations, such as the Cambrian explosion and the Great Ordovician biodiversification event, the invasion of the land, and the end-Permian mass extinction. This volume set provides innovative reviews of the major evolutionary events in the history of life from an ichnologic perspective. Because the long temporal range of trace fossils has been commonly emphasized, biogenic structures have been traditionally overlooked in macroevolution. However, comparisons of ichnofaunas through geologic time do reveal the changing ecology of organism-substrate interactions. The use of trace fossils in evolutionary paleoecology represents a new trend that is opening a window for our understanding of major evolutionary radiations and mass extinctions. Trace fossils provide crucial evidence for the recognition of spatial and temporal patterns and processes associated with paleoecologic breakthroughs.

Download or read book Ichnology written by Luis A. Buatois and published by Cambridge University Press. This book was released on 2011-08-11 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ichnology is the study of traces created in the substrate by living organisms. This is the first book to systematically cover basic concepts and applications in both paleobiology and sedimentology, bridging the gap between the two main facets of the field. It emphasizes the importance of understanding ecologic controls on benthic fauna distribution and the role of burrowing organisms in changing their environments. A detailed analysis of the ichnology of a range of depositional environments is presented using examples from the Precambrian to the recent, and the use of trace fossils in facies analysis and sequence stratigraphy is discussed. The potential for biogenic structures to provide valuable information and solve problems in a wide range of fields is also highlighted. An invaluable resource for researchers and graduate students in paleontology, sedimentology and sequence stratigraphy, this book will also be of interest to industry professionals working in petroleum geoscience.

Download or read book Methodological Naturalism and Planetary Humanism A Worldview for the 21st Century written by Guido O. Perez, MD and published by Xlibris Corporation. This book was released on 2011-09-30 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews a Naturalistic worldview based on a scientifi c understanding of the world and the broad perspective of cosmic evolution. We are the product of a long evolutionary process that has been marked by four pivotal events: the Big-Bang, the appearance of life, the emergence of mind and the evolution of culture. The issue of whether or not the universe had a beginning remains undefi ned. The origin of life from inanimate matter also remains undefi ned, but the evolution of life forms by natural selection is supported by many lines of evidence. The origin of mind and consciousness can be traced to the evolution of neurons in multicellular animals. These cells have numerous extensions capable of forming connections and infl uencing the function of distantly located cells. Most scientists adopt a monist physicalist view and reject the existence of substance dualism. Evolutionary psychology holds that human nature is the result of our genes and their interaction with the environment. Aided by their superior cognitive abilities, and by the transmission of knowledge, modern humans have created a rich culture. Because we can not prove that everything is physical, it is better to reject Ontologic Naturalism and embrace Methodological Naturalism. This worldview has an ethical, social and political dimension, best described by Planetary Humanism, a form of humanism that is not anthropocentric and is global and ecologic in scope.
