Book Description
As shown in the text, there can be little doubt that the genetic mechanism is, for all practical purposes, equivalent to life itself. Consequently, it is unrealistic to seek knowledge of the origin of life and its subsequent evolution without si multaneously searching for an understanding of how this apparatus arose and evolved. Fortunately, the annual publication over the recent years of thousandS" of papers dealing with the genetic processes has brought the state of knowledge to a level where a synthesis of their major details in relation to life's history is feasible. Because of the voluminous body of literature, no single book can pos sibly treat all the ramifications of this fundamental subject; subdivision into multiple volumes is necessary. This volume, the first of a trilogy, explores the molecular aspects of the problem in connection with the precellular aspects up to the point of the origin of the cell. The second, currently in progress, is con cerned with the subsequent evolution of the cell as revealed by the energy related organelles and their genetic apparatuses and by ultrastructural details of other cellular parts. The third volume, as presently planned, deals with devel opmental, immunological, and other complexities at the organismic level and, in so doing, throws additional light on basic properties of the genetic processes themselves. Thus, the genetic apparatus provides the warp, and evolution the woof, of the intricate fabric that emerges.

Book Description
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.

Book Description
This book presents 19 selected contributions to the 16th Evolutionary Biology Meeting, which took place in September 2012 in Marseilles. The aims of these annual meetings, which gather together leading evolutionary biologists and other scientists, are to promote the exchange of ideas and to encourage interdisciplinary collaborations. The first chapter deals with the history of a great discovery: The first experiments on ascidian and sea urchin egg fertilization. The remaining contributions are grouped under the following categories: · Evolutionary biology concepts · Exobiology and the origin of life · Evolutionary mechanisms Offering an up-to-date overview of recent findings in the field of evolutionary biology, this book is an invaluable source of information for scientists, teachers and advanced students.

Book Description
Early Thoughts on RNA and the Origin of Life The full impact of the essential role of the nucleic acids in biological systems was forcefully demonstrated by the research community in the 1950s. Although Avery and his collaborators had identified DNA as the genetic material responsible for the transformation of bacteria in 1944, it was not until the early 1950s that the Hershey-Chase experiments provided a more direct demonstration of this role. Finally, the structural DNA double helix proposed by Watson and Crick in 1953 clearly created a structural frame work for the role of DNA as both information carrier and as a molecule that could undergo the necessary replication needed for daughter cells. Research continued by Kornberg and his colleagues in the mid-1950s emphasized the biochemistry and enzymology of DNA replication. At the same time, there was a growing interest in the role of RNA. The 1956 dis covery by David Davies and myself showed that polyadenylic acid and polyuridylic acid could form a double-helical RNA molecule but that it differed somewhat from DN A A large number of experiments were subsequendy carried out with synthetic polyribonucleotides which illustrated that RNA could form even more complicated helical structures in which the specificity of hydrogen bonding was the key element in determining the molecular conformation. Finally, in I960,1 could show that it was possible to make a hybrid helix.

Book Description
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

Book Description
Systematically explores the early origins and basic definition of life. Investigates the major theories of the origins of life in light of modern research with the aim of distinguishing between the necessary and the optional and between deterministic and random influences in the emergence of what we call ‘life.’ Treats and views life as a cosmic phenomenon whose emergence and driving force should be viewed independently from its Earth-bound natural history. Synthesizes all the fundamental life-related developments in a comprehensive scenario, and makes the argument that understanding life in its broadest context requires a material-independent perspective that identifies its essential fingerprints
