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.

This book was released on 2008-10-15 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did life begin on the early Earth? We know that life today is driven by the universal laws of chemistry and physics. By applying these laws over the past ?fty years, en- mous progress has been made in understanding the molecular mechanisms that are the foundations of the living state. For instance, just a decade ago, the ?rst human genome was published, all three billion base pairs. Using X-ray diffraction data from crystals, we can see how an enzyme molecule or a photosynthetic reaction center steps through its catalytic function. We can even visualize a ribosome, central to all life, translate - netic information into a protein. And we are just beginning to understand how molecular interactions regulate thousands of simultaneous reactions that continuously occur even in the simplest forms of life. New words have appeared that give a sense of this wealth of knowledge: The genome, the proteome, the metabolome, the interactome. But we can’t be too smug. We must avoid the mistake of the physicist who, as the twentieth century began, stated con?dently that we knew all there was to know about physics, that science just needed to clean up a few dusty corners. Then came relativity, quantum theory, the Big Bang, and now dark matter, dark energy and string theory. Similarly in the life sciences, the more we learn, the better we understand how little we really know. There remains a vast landscape to explore, with great questions remaining.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the lectures presented at the second course of the International School of Space Chemistry held in Erice (Sicily) from October 20 - 30 1991 at the "E. Majorana Centre for Scientific Culture". The course was attended by 58 participants from 13 countries. The Chemistry of Life's Origins is well recognized as one of the most critical subjects of modem chemistry. Much progress has been made since the amazingly perceptive contributions by Oparin some 70 years ago when he first outlined a possible series of steps starting from simple molecules to basic building blocks and ultimate assembly into simple organisms capable of replicating, catalysis and evolution to higher organisms. The pioneering experiments of Stanley Miller demonstrated already forty years ago how easy it could have been to form the amino acids which are critical to living organisms. However we have since learned and are still learning a great deal more about the primitive conditions on earth which has led us to a rethinking of where and how the condition for prebiotic chemical processes occurred. We have also learned a great deal more about the molecular basis for life. For instance, the existence of DNA was just discovered forty years ago.

This book was released on 2019-10-29 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studying the origin of life is one of man’s greatest achievements over the last sixty years. The fields of interest encompassed by this quest are multiple and interdisciplinary: chemistry, physics, biology, biochemistry, mathematics, geology but also statistics, atmospheric science, meteorology, oceanography, and astrophysics. Recent scientific discoveries, such as water on Mars and the existence of super-Earths with atmospheres similar to primordial Earth, have pushed researchers to simulate prebiotic conditions in explaining the abiotic formation of molecules essential to life. This collection of articles offers an overview of recent discoveries in the field of prebiotic chemistry of biomolecules, their formation and selection, and the evolution of complex chemical systems.

Download or read book Chemical Evolution Origin Of Life written by Julian Chela-Flores, PhD and published by A. Deepak Publishing. This book was released on 1992-12-31 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses some important open questions in this interdisciplinary field of research. In spite of its broad scope, ranging from the earliest evidence of life on earth to the search for extraterrestrial intelligence, the main focus is on chemical evolution. Once the macromolecules of life were formed, the evolution of the earliest life forms enhanced the importance of chirality. This led to the highly asymmetric environment of the macromolecules of the living cell the hallmark of life itself. The subject of chirality, in particular, is discussed in depth: the status of the weak force as the only true chiral influence is presented. A substantial number of papers review both the theoretical as well as the experimental basis of the origin of biochirality. A second broad area discussed in detail is the RNA world. Some successes of this hypothesis are highlighted; the hierarchy of previous evolutionary stages leading to the origin of life, such as the pyrophosphate world, are considered. The question is raised whether useful hints may still be inferred from molecular fossils existing in contemporary cells. Contents The Origin, Evolution, and Distribution of Life in the Universe C.

Download or read book The Principles of Life written by Tibor Ganti and published by Oxford University Press. This book was released on 2003-09-18 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning with a new essay, "Levels of Life and Death," Tibor Gánti develops three general arguments about the nature of life. In "The Nature of the Living State," Professor Gánti answers Francis Crick's puzzles about "life itself," offering a set of reflections on the parameters of the problems to be solved in origins of life research and, more broadly, in the search for principles governing the living state in general. "The Principle of Life" describes in accessible language Gánti's chief insight about the organization of living systems-his theory of the "chemoton," or chemical automaton. The simplest chemoton model of the living state consists of three chemically coupled subsystems: an autocatalytic metabolism, a genetic molecule and a membrane. Gánti offers a fresh approach to the ancient problem of "life criteria," articulating a basic philosophy of the units of life applicable to the deepest theoretical considerations of genetics, chemical synthesis, evolutionary biology and the requirements of an "exact theoretical biology." New essays by Eörs Szathmáry and James Griesemer on the biological and philosophical significance of Gánti's work of thirty years indicate not only the enduring theoretical significance, but also the continuing relevance and heuristic power of Gánti's insights. New endnotes by Szathmáry and Griesemer bring this legacy into dialogue with current thought in biology and philosophy. Gánti's chemoton model reveals the fundamental importance of chemistry for biology and philosophy. Gánti's technical innovation - cycle stoichiometry - at once captures the fundamental fact that biological systems are organized in cycles and at the same time offers a way to understand what it is to think chemically. Perhaps most fundamentally, Gánti's chemoton model avoids dualistic thinking enforced by the dichotomies of modern biology: germ and soma, gene and character, genotype and phenotype.
