Astrobiology: An Evolutionary Approach provides a full course in astrobiology with an emphasis on abiogenesis and evolution. The book presents astrobiology both as a developing science and as the science of the future. The origins of life and the possibility of life elsewhere continues to be a subject of scientific and philosophical examination. These topics evolve with time as our understanding of life itself and the laws of chemical and biological evolution evolve. Astrobiology: An Evolutionary Approach aims both to provide a foundation in astrobiology and to describe the most challenging questions and problems in the field. The book begins with an overview of astrobiology, the origin of elements, and the formation of the solar system, planets, and exoplanets. Other topics covered include prebiotic synthesis of biochemical compounds, transition from abiotic to biotic, microorganisms in space, the roles of silicon in life, encapsulation of organic materials in protocells, cold and dry limits of life, virolution, and more. The contributors explore different aspects of astrobiology, reflecting the exciting journeys of their own research. This book will inspire students to explore the endless possibilities in astrobiology. The book includes end-of-chapter questions, a glossary of terms, and recommended references, making it ideal for use as a classroom text.

The search for life in the universe, once the stuff of science fiction, is now a robust worldwide research program with a well-defined roadmap probing both scientific and societal issues. This volume examines the humanistic aspects of astrobiology, systematically discussing the approaches, critical issues, and implications of discovering life beyond Earth. What do the concepts of life and intelligence, culture and civilization, technology and communication mean in a cosmic context? What are the theological and philosophical implications if we find life - and if we do not? Steven J. Dick argues that given recent scientific findings, the discovery of life in some form beyond Earth is likely and so we need to study the possible impacts of such a discovery and formulate policies to deal with them. The remarkable and often surprising results are presented here in a form accessible to disciplines across the sciences, social sciences, and humanities.

Astrobiology of Earth studies the fortuitous combination of numerous cosmic factors that together produced the special environment which enabled the emergence, persistence and evolution of life on our own planet, culminating in humanity. This environment has been subject to constant and chaotic change during life's 3.6 billion year history. The geologically very recent appearance of humans and their effect on the biosphere isdiscussed in relation to its deterioration as well as climate change. The search for extraterrestrial life is considered with a view to the suggestion that humans may escape a depleted Earth by colonizing the universe.

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.

The proposal of the School was made in 1998 to three institutions, which responded enthusiastically: The Abdus Salam International Centre for Theoretical Physics (ICTP), its main co-sponsor, the International Centre for Genetic Engineering and Biotechnology, both in Trieste, Italy, and the Chancellor's Office, Universidad Simon Bolfvar (USB). The secretarial and logistic support was provided in Trieste by the ICTP and in Caracas by USB and the IDEA Convention Center. In addition the event was generously supported by the following institutes, agencies, foundations and academies: NASA Headquarters, European Space Agency, TALVEN Programme, (Delegacion Permanente de Venezuela ante la UNESCO), The SETI Institute, Centro Latinoamericano .de Ffsica, The Third World Academy of Sciences, Academia de Ciencias Ffsicas, Matematicas y Naturales, Red Latinoamericana de Biologfa, The Planetary Society, The Latin American Academy of Sciences (Fondo ACAL), Alberto Vollmer Foundation, Inc, Fundacion J. Oro, Associated to the Catalonian Research Foundation, Red Latinoamericana de Astronomfa and Colegio Emil Friedman. A total of 36 lectures were delivered by 20 lecturers, of which 14 were from the following countries: Argentina, Mexico, Italy, Spain and the USA. Six lecturers were from the host country. In addition there were 5 chairpersons from the host country that were not participants; two participants acted as chairpersons (Pedro Benitez and Tomas Revilla).
