Download or read book Clay Minerals and the Origin of Life PDF or another Format written by Alexander Graham Cairns-Smith and published by CUP Archive. This book was released on 1986-12-18 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the edited proceedings of a conference seeking to clarify the possible role of clays in the origin of life on Earth. At the heart of the problem of the origin of life lie fundamental questions such as: What kind of properties is a model of a primitive living system required to exhibit and what would its most plausible chemical and molecular makeup be? Answers to these questions have traditionally been sought in terms of properties that are held to be common to all contemporary organisms. However, there are a number of different ideas both on the nature and on the evolutionary priority of 'common vital properties', notably those based on protoplasmic, biochemical and genetic theories of life. This is therefore the first area for consideration in this volume and the contributors then examine to what extent the properties of clay match those required by the substance which acted as the template for life.

Download or read book How Molecular Forces and Rotating Planets Create Life PDF or another Format written by Jan Spitzer and published by MIT Press. This book was released on 2021-02-09 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: A reconceptualization of origins research that exploits a modern understanding of non-covalent molecular forces that stabilize living prokaryotic cells. Scientific research into the origins of life remains exploratory and speculative. Science has no definitive answer to the biggest questions--"What is life?" and "How did life begin on earth?" In this book, Jan Spitzer reconceptualizes origins research by exploiting a modern understanding of non-covalent molecular forces and covalent bond formation--a physicochemical approach propounded originally by Linus Pauling and Max Delbrück. Spitzer develops the Pauling-Delbrück premise as a physicochemical jigsaw puzzle that identifies key stages in life's emergence, from the formation of first oceans, tidal sediments, and proto-biofilms to progenotes, proto-cells and the first cellular organisms.
Download or read book Darwin Strikes Back PDF or another Format written by Thomas Woodward and published by Baker Books. This book was released on 2006-11-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The debate between proponents of Darwinism and those of Intelligent Design has reached the status of a full-scale public battle. With stories of qualifying statements about evolution in public school textbooks and the recent 70th anniversary of the Scopes Monkey trial in the news, the question about our origins will not be put to rest. Following up his award-winning Doubts about Darwin, Thomas Woodward traces the continuing saga of the ID movement in Darwin Strikes Back. Focusing on the emerging key players on both sides--Michael Behe, William Dembski, Kenneth Miller, Robert Pennock, and more--Woodward helps readers navigate the tangled maze of public debate, including anti-ID activism from Christians, and shows them what might be coming next.
Download or read book The Origin of Life in Fire and Ice PDF or another Format written by Peter R. Clements and published by Bentham Science Publishers. This book was released on 2021-12-27 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Origin of Life in Fire and Ice, the author proposes a simple and direct path which may have caused the formation of one of the earliest organisms described using observations found in scientific literature: the last universal common ancestor (LUCA). The path is proposed to take place in the environment provided by hot springs in the presence of snow and ice, thus creating the ‘fire and ice’ conditions. The author guides the reader through several steps that ultimately lead to the beginning of life on our planet as we know it. The journey starts from the delivery of water and organic compounds to the early Earth by comet and asteroid impacts, progressing to the formation of vesicles in geysers, the entrapment of clay particles, amino acids and other ingredients in the vesicles, the formation of template-directed peptides, the elongation to peptides with catalytic activity, the association of catalytic peptides with aromatic compounds (including purines and pyrimidines), peptide catalyzed development of nucleotides, polymerization of nucleotides to RNA, the RNA world, and the stereochemical association with amino acids and peptides into the RNA-peptide world. These steps allow the RNA world to develop a code which forms the basis of the genetic code and ushers in the advent of LUCA. The fiery and icy path to the origin of life is simplified in this book for anyone interested in this intriguing subject.

Download or read book The Genesis Quest PDF or another Format written by Michael Marshall and published by University of Chicago Press. This book was released on 2021-09-17 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Some have argued that life began in the chemical-rich seas of the early Earth, the famous primordial soup, while others are convinced that life began in strange vents pumping hot water out of the sea floor, where the chemical reactions that sustain living cells could get started. Or perhaps life began in volcanic ponds on land, or in meteorite impact zones, or even in beds of clay. Each idea has attracted staunch believers who promote it with an almost religious fervor. But the story of life's origins is more than this: it is a story that takes in some of the greatest discoveries in modern biology, from cells to DNA, and evolution to life's family tree. This book is the first full history of the scientists who struggled to explain one of the greatest mysteries of all: how and why life began"--

Download or read book Origins PDF or another Format written by Frank H. T. Rhodes and published by Cornell University Press. This book was released on 2016-07-28 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fossils are the fragments from which, piece by laborious piece, the great mosaic of the history of life has been constructed. Here and there, we can supplement these meager scraps by the use of biochemical markers or geochemical signatures that add useful information, but, even with such additional help, our reconstructions and our models of descent are often tentative. For the fossil record is, as we have seen, as biased as it is incomplete. But fragmentary, selective, and biased though it is, the fossil record, with all its imperfections, is still a treasure. Though whole chapters are missing, many pages lost, and the earliest pages so damaged as to be, as yet, virtually unreadable, this—the greatest biography of all—is one in whose closing pages we find ourselves."—from Origins In Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life’s past, its long and slow development, and its intricate interdependencies. Rhodes’s accessible and extensively illustrated treatment of the origins narrative describes the nature of the search for prehistoric life, the significance of geologic time, the origin of life, the emergence and spread of flora and fauna, the evolution of primates, and the emergence of modern humans.

This book was released on 2012-03-19 with total page 934 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genesis – In The Beginning deals with the origin and diversity of Life and early biological evolution and discusses the question of where (hot or cold sources) and when the beginning of Life took place. Among the sections are chapters dealing with prebiotic chemical processes and considering self-replication of polymers in mineral habitats. One chapter is dedicated to the photobiological regime on early Earth and the emergence of Life. This volume covers the role of symmetry, information and order (homochrial biomolecules) in the beginning of Life. The models of protocells and the genetic code with gene transfer are important topics in this volume. Three chapters discuss the Panspermia hypothesis (to answer “Are we from outer Space?”). Other chapters cover the Astrobiological aspects of Life in the Universe in extraterrestrial Planets of the Solar System and deal with cometary hydrosphere (and its connection to Earth). We conclude with the history and frontiers of Astrobiogy.

Download or read book Minerals latu sensu and Human Health PDF or another Format written by Celso Gomes and published by Springer Nature. This book was released on 2021-05-18 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a comprehensive academic review of both positive and negative effects of minerals on human health and quality of life. The book adopts the concept of mineral latu sensu (mineral l.s.), which encompasses a broad spectrum of natural, inorganic, solid, and crystalline, of natural and inorganic chemical elements (metals and metalloids), of modified natural minerals, of biominerals, and of syntetic minerals, all products that branch across the disciplines of earth, soil, environmental, materials, nutrition, and health sciences. Using this broad framework, the authors are able to provide a multidisciplinary assessment on many types of minerals which can be essential, beneficial and hazardous to human health, covering applications in medical geology, medical hydrology or balneotherapy, pharmacology, chemistry, nutrition, and biophysics. The book performs historical analyses of the uses of minerals for therapeutic and cosmetic purposes to better understand current trends and developments in mineral research and human health. The book will be of interest to students, public health officials, environmental agencies and researchers from various disciplines, as well as scientific societies and organizations focusing on medical geology, health resort medicine (crenotherapy, hydrotherapy and climatotherapy), and on pharmaceutical, cosmetic and biomedical applications.
