Book Description
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.

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
The search for life in the solar system and beyond has to date been governed by a model based on what we know about life on Earth (terran life). Most of NASA's mission planning is focused on locations where liquid water is possible and emphasizes searches for structures that resemble cells in terran organisms. It is possible, however, that life exists that is based on chemical reactions that do not involve carbon compounds, that occurs in solvents other than water, or that involves oxidation-reduction reactions without oxygen gas. To assist NASA incorporate this possibility in its efforts to search for life, the NRC was asked to carry out a study to evaluate whether nonstandard biochemistry might support life in solar system and conceivable extrasolar environments, and to define areas to guide research in this area. This book presents an exploration of a limited set of hypothetical chemistries of life, a review of current knowledge concerning key questions or hypotheses about nonterran life, and suggestions for future research.

Book Description
Origins of Life on the Earth and in the Cosmos, Second Edition, suggests answers to the age-old questions of how life arose in the universe and how it might arise elsewhere. This thorough revision of a very successful text describes key events in the evolution of living systems, starting with the creation of an environment suitable for the origins of life. Whereas one may never be able to reconstruct the precise pathway that led to the origin of life on earth, one can certainly make some plausible reconstructions of it. Such discussions have greatly expanded our understanding of the principles of chemical evolution and how they compare and contrast with the principles of biological evolution. The text is strong on biochemistry and its recent applications to origins' research. - Provides an excellent review of basic biochemistry an evolution - Written in a clear, concise style for scientists, students, and readers interested in a scientific inquiry into the origins of life - Written by an authority in the field, and brought fully up-to-date in light of new research - Pulls together valuable information not found in a single source - Organized and presented in a manner conductive for use in a college course - Heavily illustrated to make difficult concepts concrete

Book Description
What is the origin of life? Molecular biology shows us one kind, but in thinking about it we must consider those generalised aspects of living organisation that are common to all conceivable forms of life. The author believes that only a combination of general biological theory and particular chemical knowledge can solve the problems of the origin and re-creation of life. This book does not fall into either the classical Haldane or Oparin schools of thought on the origin of life, but advances a thesis of its own, which, according to Professor C.H. Waddington, is one of the most important recent intellectual developments in this field. Part I considers the role of molecular biology in formulating a view of life as it exists now. Part II turns to more general aspects of the organisation of matter. In Part III the author advances his own theories on the origin of life—theories which are both revolutionary and reactionary. As he remarks, 'If my conclusions are correct it may be difficult to find the right system, but it would be easy to make a very simple organism once we have.'

Book Description
A brilliant book celebrating improbability as the engine that drives life, by the acclaimed author of The Selfish Gene and The Blind Watchmaker. The human eye is so complex and works so precisely that surely, one might believe, its current shape and function must be the product of design. How could such an intricate object have come about by chance? Tackling this subject—in writing that the New York Times called "a masterpiece"—Richard Dawkins builds a carefully reasoned and lovingly illustrated argument for evolutionary adaptation as the mechanism for life on earth. The metaphor of Mount Improbable represents the combination of perfection and improbability that is epitomized in the seemingly "designed" complexity of living things. Dawkins skillfully guides the reader on a breathtaking journey through the mountain's passes and up its many peaks to demonstrate that following the improbable path to perfection takes time. Evocative illustrations accompany Dawkins's eloquent descriptions of extraordinary adaptations such as the teeming populations of figs, the intricate silken world of spiders, and the evolution of wings on the bodies of flightless animals. And through it all runs the thread of DNA, the molecule of life, responsible for its own destiny on an unending pilgrimage through time. Climbing Mount Improbable is a book of great impact and skill, written by the most prominent Darwinian of our age.

Book Description
Always a controversial and compelling topic, the origin of life on Earth was considered taboo as an area of inquiry for science as recently as the 1950s. Since then, however, scientists working in this area have made remarkable progress, and an overall picture of how life emerged is coming more clearly into focus. We now know, for example, that the story of life's origin begins not on Earth, but in the interiors of distant stars. This book brings a summary of current research and ideas on life's origin to a wide audience. The contributors, all of whom received the Oparin/Urey Gold Medal of the International Society for the Study of the Origin of Life, are luminaries in the fields of chemistry, paleobiology, and astrobiology, and in these chapters they discuss their life's work: understanding the what, when, and how of the early evolution of life on Earth. Presented in nontechnical language and including a useful glossary of scientific terms, Life's Origin gives a state-of-the-art encapsulation of the fascinating work now being done by scientists as they begin to characterize life as a natural outcome of the evolution of cosmic matter.
