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.

This classic of biochemistry offered the first detailed exposition of the theory that living tissue was preceded upon Earth by a long and gradual evolution of nitrogen and carbon compounds. "Easily the most scholarly authority on the will be a landmark for discussion for a long time to come." — New York Times.

This book addresses the question of how life may have arisen on earth, in the spirit of an intriguing detective story. It relies on the methods of Sherlock Holmes, in particular his principle that one should use the most paradoxical features of a case to crack it. This approach to the essential biological problems is not merely light-hearted, but a fascinating scrutiny of some very fundamental questions. 'I know of no other book that succeeds as well as this one in maintaining the central question in focus throughout. It is a summary of the best evolutionary thinking as applied to the origins of life in which the important issues are addressed pertinently, economically and with a happy recourse to creative analogies.' Nature '... a splendid story - and a much more convincing one than the molecular biologists can offer as an alternative. Cairns-Smith has argued his case before in the technical scientific literature, here he sets it out in a way from which anyone - even those whose chemistry and biology stopped at sixteen - can learn.' New Statesman

Between Necessity And Probability Searching For The Definition And Origin Of Life

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

How did life on earth originate? Did replication or metabolism come first in the history of life? In this book, Freeman Dyson examines these questions and discusses the two main theories that try to explain how naturally occurring chemicals could organize themselves into living creatures. The majority view is that life began with replicating molecules, the precursors of modern genes. The minority belief is that random populations of molecules evolved metabolic activities before exact replication existed. Dyson analyzes both of these theories with reference to recent important discoveries by geologists and chemists. His main aim is to stimulate experiments that could help to decide which theory is correct. This second edition covers the enormous advances that have been made in biology and geology in the past and the impact they have had on our ideas about how life began. It is a clearly-written, fascinating book that will appeal to anyone interested in the origins of life.

The return of Halley's Cornet in 1986 has generated much ex citement in the scientific community with preparations already afoot for an International Cornet Watch and a cornet launch by the European Space Community, the Japanese and Soviet Space Scientists. The meet ing held at the University of Maryland in October 1980 was primarily stimulated by the preparations for further study of this cornet and by one of the most important unanswered questions related to comets, name ly, whether they may have made a eontribution to the origin of life on earth. Our un"derstanding of the role of comets in the origin of life must necessarily come from our studies of the astronomy and the chem istry of comets. Some clues to the processes which led to the for mation of organic molecules and eventually to the appearance of life have come from these studies of comets, perhaps the most ancient of all objects in our solar system. Whether there is, however, a biology of comets still remains to be seen, although some claims have been made that perhaps comets might themselves provide an environment for even the beginnings of life. Scientists with the latest available information on comets and differing opinions as to the role of comets in the origin of life attended this symposium. The formal papers presented are now being made available to the students of chemical evolution within the pages of this volume.
