Origin Of Life

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?

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

Life arose on Earth more than three billion years ago. How the first self-replicating systems emerged from prebiotic chemistry and evolved into primitive cell-like entities is an area of intense research, spanning molecular and cellular biology, organic chemistry, cosmology, geology, and atmospheric science. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology provides a comprehensive account of the environment of the early Earth and the mechanisms by which the organic molecules present may have self-assembled to form replicating material such as RNA and other polymers. The contributors examine the energetic requirements for this process and focus in particular on the essential role of semi-permeable compartments in containment of primitive genetic systems. Also covered in the book are new synthetic approaches for fabricating cellular systems, the potentially extraterrestrial origin of life's building blocks, and the possibility that life once existed on Mars. Comprising five sections Setting the Stage, Components of First Life, Primitive Systems, First Polymers, and Transition to a Microbial World it is a vital reference for all scientists interested in the origin of life on Earth and the likelihood that it has arisen on other planets

The origins of life remains one of the great unsolved mysteries of science. Growing evidence suggests that the first organisms lived deep underground, in environments previously thought to be uninhabitable, and that microbes carried inside rocks have travelled between Earth and Mars. But the question remains: how can life spring into being from non-living chemicals? THE FIFTH MIRACLE reveals the remarkable new theories and discoveries that seem set to transform our understanding of life's role in the unfolding drama of the cosmos.

The field of planetary biology and chemical evolution draws together experts in astronomy, paleobiology, biochemistry, and space science who work together to understand the evolution of living systems. This field has made exciting discoveries that shed light on how organic compounds came together to form self-replicating molecules-the origin of life. This volume updates that progress and offers recommendations on research programs-including an ambitious effort centered on Mars-to advance the field over the next 10 to 15 years. The book presents a wide range of data and research results on these and other issues: The biogenic elements and their interaction in the interstellar clouds and in solar nebulae. Early planetary environments and the conditions that lead to the origin of life. The evolution of cellular and multicellular life. The search for life outside the solar system. This volume will become required reading for anyone involved in the search for life's beginnings-including exobiologists, geoscientists, planetary scientists, and U.S. space and science policymakers.

Theoretical biology is still in its early stages as an academic discipline. There is even little agreement as to what topics it should deal with or in what manner it should precede; and it is only recently that philosophers felt called upon to notice the relevance of biological topics as evolution or perception to their traditional problems. This work is a publication of the International Union of Biological Sciences, the central organization of all the branches of biology. The main focus here is to explore the possibility of formulating some frame of concepts and methods around which theoretical biology can grow. The intention of this collective effort was that discussions would be concerned, not with the theory of particular biological processes, such as membrane permeability, genetics, and neural activity, but rather with an attempt to discover and formulate general concepts and logical relations characteristic of living as contrasted with inorganic systems. Further, this project is a consideration of implications these might have for general philosophy. Many well-known scientists contributed to this volume, such as J. Maynard Smith, Ernst Mayr, Brian Goodwin, and RenÚ Thom. The Origin of Life: Toward a Theoretical Biology explores the character of the problems facing any theory of general biology. It contains a series of chapters and exchanges discussing such topics as the origin of life, cellular differentiation, morphogensis, evolution, and indeterminacy in biological and physical systems, the organization of the brain, the statistical mechanics of non-linear oscillators, and many other topics. This is a pioneering volume by recognized leaders in an emerging field—the first of four such works.

Modern Trends in Physiological Sciences, Volume 6: Aspects of the Origin of Life presents the possible ways of the chemical evolution of the Earth's surface before the origination of life. This book examines the evolutionary aspects of the biochemistry of cells and organisms. Organized into 20 chapters, this volume begins with an overview of the conditions that characterized the physical state of the Earth during the earliest periods following its formation and development. This text then examines the content of elementary oxygen as the most remarkable aspect of the Earth's atmosphere. Other chapters consider the fundamental propositions concerning the biosphere, which is regarded as important to the geochemical processes of the Earth. This book discusses as well the history of the whole substance of Earth, which determines how far abiogenic synthesis could proceed and what was the state of the Earth when life came into being. Biochemists and scientists will find this book useful.
