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.

Book Synopsis When the Invasion of Land Failed by : George R. McGhee, Jr.
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.
Book Synopsis The Rise and Fall of the Ediacaran Biota by : Patricia Vickers-Rich
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.
Book Synopsis The Trace-Fossil Record of Major Evolutionary Events by : M. Gabriela Mángano
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.
Book Synopsis Convergent Evolution on Earth by : George R. McGhee, Jr.
Download or read book Convergent Evolution on Earth written by George R. McGhee, Jr. and published by MIT Press. This book was released on 2019-10-15 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of patterns of convergent evolution on Earth that suggests where we might look for similar convergent forms on other planets. Why does a sea lily look like a palm tree? And why is a sea lily called a “lily” when it is a marine animal and not a plant? Many marine animals bear a noticeable similarity in form to land-dwelling plants. And yet these marine animal forms evolved in the oceans first; land plants independently and convergently evolved similar forms much later in geologic time. In this book, George McGhee analyzes patterns of convergent evolution on Earth and argues that these patterns offer lessons for the search for life elsewhere in the universe. Our Earth is a water world; 71 percent of the earth's surface is covered by water. The fossil record shows that multicellular life on dry land is a new phenomenon; for the vast majority of the earth's history—3,500 million years of its 4,560 million years of existence—complex life existed only in the oceans. Explaining that convergent biological evolution occurs because of limited evolutionary pathways, McGhee examines examples of convergent evolution in forms of feeding, immobility and mobility, defense, and organ systems. McGhee suggests that the patterns of convergent evolution that we see in our own water world indicate the potential for similar convergent forms in other water worlds. We should search for extraterrestrial life on water worlds, and for technological life on water worlds with continental landmasses.
Book Synopsis The Shape of Life by : Rudolf A. Raff
Download or read book The Shape of Life written by Rudolf A. Raff and published by University of Chicago Press. This book was released on 2012-12-14 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rudolf Raff is recognized as a pioneer in evolutionary developmental biology. In their 1983 book, Embryos, Genes, and Evolution, Raff and co-author Thomas Kaufman proposed a synthesis of developmental and evolutionary biology. In The Shape of Life, Raff analyzes the rise of this new experimental discipline and lays out new research questions, hypotheses, and approaches to guide its development. Raff uses the evolution of animal body plans to exemplify the interplay between developmental mechanisms and evolutionary patterns. Animal body plans emerged half a billion years ago. Evolution within these body plans during this span of time has resulted in the tremendous diversity of living animal forms. Raff argues for an integrated approach to the study of the intertwined roles of development and evolution involving phylogenetic, comparative, and functional biology. This new synthesis will interest not only scientists working in these areas, but also paleontologists, zoologists, morphologists, molecular biologists, and geneticists.
Book Synopsis The Invertebrate Tree of Life by : Gonzalo Giribet
Download or read book The Invertebrate Tree of Life written by Gonzalo Giribet and published by Princeton University Press. This book was released on 2020-03-03 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most up-to-date book on invertebrates, providing a new framework for understanding their place in the tree of life In The Invertebrate Tree of Life, Gonzalo Giribet and Gregory Edgecombe, leading authorities on invertebrate biology and paleontology, utilize phylogenetics to trace the evolution of animals from their origins in the Proterozoic to today. Phylogenetic relationships between and within the major animal groups are based on the latest molecular analyses, which are increasingly genomic in scale and draw on the soundest methods of tree reconstruction. Giribet and Edgecombe evaluate the evolution of animal organ systems, exploring how current debates about phylogenetic relationships affect the ways in which aspects of invertebrate nervous systems, reproductive biology, and other key features are inferred to have developed. The authors review the systematics, natural history, anatomy, development, and fossil records of all major animal groups, employing seminal historical works and cutting-edge research in evolutionary developmental biology, genomics, and advanced imaging techniques. Overall, they provide a synthetic treatment of all animal phyla and discuss their relationships via an integrative approach to invertebrate systematics, anatomy, paleontology, and genomics. With numerous detailed illustrations and phylogenetic trees, The Invertebrate Tree of Life is a must-have reference for biologists and anyone interested in invertebrates, and will be an ideal text for courses in invertebrate biology. A must-have and up-to-date book on invertebrate biology Ideal as both a textbook and reference Suitable for courses in invertebrate biology Richly illustrated with black-and-white and color images and abundant tree diagrams Written by authorities on invertebrate evolution and phylogeny Factors in the latest understanding of animal genomics and original fossil material
Book Synopsis The Evolution Underground by : Anthony J Martin
Download or read book The Evolution Underground written by Anthony J Martin and published by Simon and Schuster. This book was released on 2017-02-07 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans have "gone underground" for survival for thousands of years, from underground cities in Turkey to Cold War-era bunkers. But our burrowing roots go back to the very beginnings of animal life on Earth. Many animal lineages alive now—including our own—only survived a cataclysmic meteorite strike 65 million years ago because they went underground.On a grander scale, the chemistry of the planet itself had already been transformed many millions of years earlier by the first animal burrows which altered whole ecosystems. Every day we walk on an earth filled with an underground wilderness teeming with life. Most of this life stays hidden, yet these animals and their subterranean homes are ubiquitous, ranging from the deep sea to mountains, from the equator to the poles. Burrows are a refuge from predators, a safe home for raising young, or a tool to ambush prey. Burrows also protect animals against all types of natural disasters. Filled with spectacularly diverse fauna, acclaimed paleontologist and ichnologist Anthony Martin reveals this fascinating, hidden world that will continue to influence and transform life on this planet.
Book Synopsis Anthropocene Poetry by : Yvonne Reddick
Download or read book Anthropocene Poetry written by Yvonne Reddick and published by Springer Nature. This book was released on 2023-11-03 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropocene Poetry: Place, Environment and Planet argues that the idea of the Anthropocene is inspiring new possibilities for poetry. It can also change the way we read and interpret poems. If environmental poetry was once viewed as linked to place, this book shows how poets are now grappling with environmental issues from the local to the planetary: climate change and the extinction crisis, nuclear weapons and waste, plastic pollution and the petroleum industry. This book intervenes in debates about culture and science, traditional poetic form and experimental ecopoetics, to show how poets are collaborating with environmental scientists and joining environmental activist movements to respond to this time of crisis. From the canonical work of Ted Hughes and Seamus Heaney, to award-winning poets Alice Oswald, Pascale Petit, Kei Miller, and Karen McCarthy Woolf, this book explores major figures from the past alongside acclaimed contemporary voices. It reveals Seamus Heaney’s support for conservation causes and Ted Hughes’s astonishingly forward-thinking research on climate change; it discusses how Pascale Petit has given poetry to Extinction Rebellion and how Karen McCarthy Woolf set sail with scientists to write about plastic pollution. This book deploys research on five poetry archives in the UK, USA and Ireland, and the author’s insider insights into the commissioning processes and collaborative methods that shaped important contemporary poetry publications. Anthropocene Poetry finds that environmental poetry is flourishing in the face of ecological devastation. Such poetry speaks of the anxieties and dilemmas of our age, and searches for paths towards resilience and resistance.

Book Synopsis The Holobiont Imperative by : Thomas C. G. Bosch
Download or read book The Holobiont Imperative written by Thomas C. G. Bosch and published by Springer. This book was released on 2016-03-08 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines how the growing knowledge of the huge range of animal-bacterial interactions, whether in shared ecosystems or intimate symbioses, is fundamentally altering our understanding of animal biology. Individuals from simple invertebrates to human are not solitary, homogenous entities but consist of complex communities of many species that likely evolved during a billion years of coexistence. Defining the individual microbe-host conversations in these consortia, is a challenging but necessary step on the path to understanding the function of the associations as a whole. The hologenome theory of evolution considers the holobiont with its hologenome as a unit of selection in evolution. This new view may have profound impact on understanding a strictly microbe/symbiont-dependent life style and its evolutionary consequences. It may also affect the way how we approach complex environmental diseases from corals (coral bleaching) to human (inflammatory bowel disease etc). The book is written for scientists as well as medically interested persons in the field of immunobiology, microbiology, evolutionary biology, evolutionary medicine and corals.
Book Synopsis Once We All Had Gills by : Rudolf A. Raff
Download or read book Once We All Had Gills written by Rudolf A. Raff and published by Indiana University Press. This book was released on 2012-07-16 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, Rudolf A. Raff reaches out to the scientifically queasy, using his life story and his growth as a scientist to illustrate why science matters, especially at a time when many Americans are both suspicious of science and hostile to scientific ways of thinking. Noting that science has too often been the object of controversy in school curriculums and debates on public policy issues ranging from energy and conservation to stem-cell research and climate change, Raff argues that when the public is confused or ill-informed, these issues tend to be decided on religious, economic, and political grounds that disregard the realities of the natural world. Speaking up for science and scientific literacy, Raff tells how and why he became an evolutionary biologist and describes some of the vibrant and living science of evolution. Once We All Had Gills is also the story of evolution writ large: its history, how it is studied, what it means, and why it has become a useful target in a cultural war against rational thought and the idea of a secular, religiously tolerant nation.

Book Synopsis Horizontal Gene Transfer in the Evolution of Pathogenesis by : Michael Hensel
Download or read book Horizontal Gene Transfer in the Evolution of Pathogenesis written by Michael Hensel and published by Cambridge University Press. This book was released on 2008-06-30 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horizontal gene transfer is a major driving force in the evolution of many bacterial pathogens. The development of high-throughput sequencing tools and more sophisticated genomic and proteomic techniques in recent years has resulted in a better understanding of this phenomenon. Written by leading experts in the field, this edited volume is aimed at graduate students and researchers and provides an overview of current knowledge relating to the evolution of microbial pathogenicity. This volume provides an overview of the mechanisms and biological consequences of the genome rearrangements resulting from horizontal gene transfer, in both prokaryotes and eukaryotes, as well as overviews of the key mobile genetic elements involved. Subsequent chapters focus on paradigms for the evolution of important bacterial pathogens, including Salmonella enterica, Streptococcus pneumoniae, and Staphylococcus aureus. The influence of socioeconomic parameters in the dissemination of transferable elements, such as antibiotic resistant genes in bacteria, is also discussed.
