Available in PDF, EPUB and Kindle. Book excerpt: In 1963, 1965 and 1967 "Symposia on Quantitative Biology of Metabolism" were organized on the pretty island of Helgoland (Biologische Anstalt) by me in col laboration with O. KINNE and F. KROGER. Unfortunately this worthy approach towards bringing together interested scholars in a regular way ceased, mainly for financial reasons, although the need for and interest in conferences like these for the exchange of ideas on special topics unchangeably persists. So I had to look for other possibilities and one of them was to try to arrange a similar con ference under the auspices of NASA. This institution, however, eventually re-. treated, although during my discussion with its representatives a new special theme gained shape. This is the topic to which this volume is devoted: Bio genesis. It is also treated in a new way that probably could be a model for. similar undertakings: a symposium by correspondence. In this new approach to scientific information exchange, manuscripts were collected by the editor and sent to every contributor for his comments. The author could then reply by means of a concluding remark. So, in many instances very valuable ideas concerning the topics of the several papers could be gathered and it is to be hoped that this procedure has conferred upon this volume a certain uniqueness. Of course, I had to observe the agreement with Springer-Verlag not to exceed the extent of the volume allotted to us.

Download or read book The Emergence of Life written by Pier Luigi Luisi and published by Cambridge University Press. This book was released on 2006-07-13 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin of life from inanimate matter has been the focus of much research for decades, both experimentally and philosophically. Luisi takes the reader through the consecutive stages from prebiotic chemistry to synthetic biology, uniquely combining both approaches. This book presents a systematic course discussing the successive stages of self-organisation, emergence, self-replication, autopoiesis, synthetic compartments and construction of cellular models, in order to demonstrate the spontaneous increase in complexity from inanimate matter to the first cellular life forms. A chapter is dedicated to each of these steps, using a number of synthetic and biological examples. With end-of-chapter review questions to aid reader comprehension, this book will appeal to graduate students and academics researching the origin of life and related areas such as evolutionary biology, biochemistry, molecular biology, biophysics and natural sciences.

Download or read book Genesis In The Beginning written by Joseph Seckbach and published by Springer Science & Business Media. This book was released on 2012-03-21 with total page 911 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.

Available in PDF, EPUB and Kindle. Book excerpt: The relationship between law and chance in the early evolution of life is the guidingtheme of this provocative study. The author explores modern ideas about the origin of life from thestandpoint of philosophy of science, emphasizing the contribution made by information theory.Küppersasserts that all life phenomena are steered by information and that this information is alreadydefined materially in a universal form at the level of the biological macromolecule. The question ofthe origin of life turns out to be the question of the origin of biological informationInformationand the Origin of Life takes up the fundamental problems of whether and, if so, to what extent theorigin of semantic information during evolution can be explained as a general phenomenon within theframework of physics and chemistry. The results could have far-reaching consequences for such fieldsas the philosophy of mind and artificial intelligence.Bernd-Olaf Küppers has long focused hisattention on basic questions of natural science and the philosophy of science at the borders ofphysics, chemistry, and biology. He has been engaged since 1971 in research at the Max PlanckInstitute for Biophysical Chemistry, and from 1979 to 1984 he held lecture courses in philosophy atthe University of Göttingen

Download or read book Abiogenesis written by Paul F. Kisak and published by Createspace Independent Publishing Platform. This book was released on 2016-08-12 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abiogenesis has become a maturing field of study as an alternative to the creationist or intelligent design theory of the origin of life on earth. Abiogenesis, Biopoiesis or OoL (Origins of Life), is the natural process of life arising from non-living matter, such as simple organic compounds. It is thought to have occurred on Earth between 3.8 and 4.1 billion years ago. Abiogenesis is studied through a combination of laboratory experiments and extrapolation from the characteristics of modern organisms, and aims to determine how pre-life chemical reactions gave rise to life on Earth. The study of abiogenesis involves geophysical, chemical, and biological considerations, with more recent approaches attempting a synthesis of all three. Many approaches investigate how self-replicating molecules, or their components, came into existence. It is generally thought that current life on Earth is descended from an RNA world, although RNA-based life may not have been the first life to have existed. The classic Miller-Urey experiment and similar research demonstrated that most amino acids, the basic chemical constituents of the proteins used in all living organisms, can be synthesized from inorganic compounds under conditions intended to replicate those of the early Earth. Various external sources of energy that may have triggered these reactions have been proposed, including lightning and radiation. Other approaches ("metabolism-first" hypotheses) focus on understanding how catalysis in chemical systems on the early Earth might have provided the precursor molecules necessary for self-replication. Complex organic molecules have been found in the Solar System and in interstellar space, and these molecules may have provided starting material for the development of life on Earth. The panspermia hypothesis alternatively suggests that microscopic life was distributed to the early Earth by meteoroids, asteroids and other small Solar System bodies and that life may exist throughout the Universe. Given the revised and more accurate models of "The Drake Equation" and the knowledge gained on the Tardigrade species, it is very probable that some simple form of life has been deposited on earth via asteroids, meteorites or some similar phenomena. It is speculated that the biochemistry of life may have begun shortly after the Big Bang, 13.8 billion years ago, during a habitable epoch when the age of the universe was only 10 to 17 million years. The panspermia hypothesis therefore answers questions of where, not how, life came to be; it only postulates that life may have originated in a locale outside the Earth. Currently, Earth remains the only place in the Universe observed to harbor life, and fossil evidence from the Earth supplies most studies of abiogenesis. Precambrian stromatolites were found in the Siyeh Formation of The Glacier National Park. A paper in the scientific journal "Nature" 2002 suggested that these 3.5 Ga (billion years) old geological formations contain fossilized cyanobacteriamicrobes. This suggests they are evidence of one of the earliest known life forms on Earth. The age of the Earth is about 4.54 billion years; the earliest undisputed evidence of life on Earth dates from at least 3.5 billion years ago, and possibly as early as the Eoarchean Era, after a geological crust started to solidify following the earlier molten Hadean Eon. Microbial mat fossils have been found in 3.48 billion-year-old sandstone in Western Australia. Other early physical evidence of biogenic substances includes graphite discovered in 3.7 billion-year-old metasedimentary rocks in southwestern Greenland, as well as "remains of biotic life" found in 4.1 billion-year-old rocks in Western Australia. According to one of the researchers, "If life arose relatively quickly on Earth ... then it could be common in the universe." This book discusses the various methods and Evidence for the development of life on Earth by natural means.
Download or read book Origin of Life written by and published by . This book was released on 2018-09-15 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abiogenesis, or informally the origin of life, is the natural process by which life arises from non-living matter, such as simple organic compounds. The transition from non-living to living entities was not a single event, but a gradual process of increasing complexity. Researchers study abiogenesis through a combination of molecular biology, paleontology, astrobiology and biochemistry, and aim to determine how pre-life chemical reactions gave rise to life. The study of abiogenesis can be geophysical, chemical, or biological, with more recent approaches attempting a synthesis of all three, as life arose under conditions that are strikingly different from those on Earth today. Life functions through the specialized chemistry of carbon and water and builds largely upon four key families of chemicals: lipids (fatty cell walls), carbohydrates (sugars, cellulose), amino acids (protein metabolism), and nucleic acids (self-replicating DNA and RNA). Any successful theory of abiogenesis must explain the origins and interactions of these classes of molecules. Many approaches to abiogenesis investigate how self-replicating molecules, or their components, came into existence. Researchers generally think that current life on Earth descends from an RNA world, although RNA-based life may not have been the first life to have existed. This book is a compilation of high quality articles from the Internet.
Download or read book Molecular Theory of Evolution written by Bernd-Olaf Küppers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this book is the physico-chemical theory of the origin of life. Although this theory is still in statu nascendi, it has been developed in recent years to the point where a coherent presentation is possible. The book is intended as an introductory text for students of physics, chemistry or biology. This interdisciplinary aim has necessitated a choice of material based on the lowest common denominator of physicists and biologists. In particular, the predominantly mathematical and biological sections have been presented at the most elementary l.evel possible. The less mathematically inclined reader can omit Sections (5.3)-(5.5), (5.7)-(5.10), (6.2), (6.3), (9.1)-(9.3), (12.1) and (13.3) without losing the overall view. For critical reading of the manuscript, for discussions and for many useful suggestions I wish to thank M. Eigen (Gottingen), w.e. Gardiner (Austin), D. Porschke (Gottingen), P. Schuster (Vienna), P.R. Wills (Auckland) and P. Woolley (Berlin). The translation of the original, German manuscript into English was kindly undertaken by Paul Woolley. During this and subsequent stages of revision he introduced a great many improvements in the text and the presentation of material. My particular thanks are due to him for his decisive contribution to this book. Last of all I wish to thank Ingeborg Lechten for typing the text in its various stages of evolution. The completion of this book is largely to be attributed to her patience and efficiency.
Download or read book Origin of Life written by David W. Deamer and published by Oxford University Press. This book was released on 2020-08-01 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: It seems likely that scientists will someday discover how life can emerge on habitable planets like the early Earth and Mars. In Origin of Life: What Everyone Needs to Know®, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections. The first section addresses questions such as: Where do the atoms of life come from? How old is Earth? What was the Earth like before life began? Where does water come from? After each question is answered, there is a follow-up: How do we know? This expands the horizon of the book, explaining how scientists reach conclusions and why we can trust these answers. The second section describes how certain organic molecules can spontaneously assemble into populations of protocells that can undergo selection and evolve toward primitive living systems. Here Deamer proposes a truly novel concept that life did not begin in the ocean but instead in fresh water hot springs on volcanic land masses resembling Hawaii today. True knowledge is not just what we know, but equally important is what we don't yet know. In the third section Deamer lists the outstanding questions that must be addressed before we can finally answer a fundamental question of biology: How can life begin?
Download or read book Sparks of Life written by James E. Strick and published by Harvard University Press. This book was released on 2009-06-01 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: How, asks James E. Strick, could spontaneous generation--the idea that living things can suddenly arise from nonliving materials--come to take root for a time (even a brief one) in so thoroughly unsuitable a field as British natural theology? No less an authority than Aristotle claimed that cases of spontaneous generation were to be observed in nature, and the idea held sway for centuries. Beginning around the time of the Scientific Revolution, however, the doctrine was increasingly challenged; attempts to prove or disprove it led to important breakthroughs in experimental design and laboratory techniques, most notably sterilization methods, that became the cornerstones of modern microbiology and sped the ascendancy of the germ theory of disease. The Victorian debates, Strick shows, were entwined with the public controversy over Darwin's theory of evolution. While other histories of the debates between 1860 and 1880 have focused largely on the experiments of John Tyndall, Henry Charlton Bastian, and others, Sparks of Life emphasizes previously understudied changes in the theories that underlay the debates. Strick argues that the disputes cannot be understood without full knowledge of the factional infighting among Darwinians themselves, as they struggled to create a socially and scientifically viable form of Darwinian science. He shows that even the terms of the debate, such as biogenesis, usually but incorrectly attributed to Huxley, were intensely contested.
