Book excerpt: Leading researchers in the area of the origin and evolution of life in the universe contributed to Chemical Evolution: Physics of the Origin and Evolution of Life. This volume provides a review of this interdisciplinary field. In 35 chapters many aspects of the origin of life are discussed by 90 authors, with particular emphasis on the early paleontological record: physical, chemical, biological, and informational aspects of life's origin, instrumentation in exobiology and system exploration; the search for habitable planets and extraterrestrial intelligent radio signals. This book contains the proceedings of the Fourth Trieste Conference on Chemical Evolution that took place in September 1995, in which scientists from a wide geographical distribution joined in a Memorial to Cyril Ponnamperuma, who was a pioneer in the field of chemical evolution, the origin of life, and exobiology, and also initiated the Trieste Conferences on Chemical Evolution and the Origin of Life. This fourth Conference was therefore dedicated to his memory. Audience: Graduate students and researchers in the many areas of basic, earth, and life sciences that contribute to the study of chemical evolution and the origin of life.

Book excerpt: This publication, in two volumes, includes most of the scientific papers presented at the first meeting of the International Society for the Study of the Origin of Life (lSSOL), held on June 25-28, 1973 in Barcelona, Spain. The first volume contains the invited articles and the second volume the contributed papers, which also appear in the 1974 and 1975 issues, respectively, of the new journal Origins of Life, published by D. Reidel. A relatively large number of meetings on the subject of the origin of life have been held in different places since 1957. In terms of its organization, scope, and number and nationality of participants, the Conference celebrated last year in Barcelona closely followed the three international conferences held earlier in Moscow, U.S.S.R., 1957, Wakulla Springs, U.S.A., 1963, and Pont-a-Mousson, France, 1970. For this reason the first ISSOL meeting was also named the 4th International Conference on the Origin of Life.

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.

Book excerpt: Leading researchers in the area of the origin, evolution and distribution of life in the universe contributed to Exobiology: Matter, Energy, and Information in the Origin and Evolution of Life in the Universe. This volume provides a review of this interdisciplinary field. In 50 chapters many aspects that contribute to exobiology are reviewed by 90 authors. These include: historical perspective of biological evolution; cultural aspects of exobiology, cosmic, chemical and biological evolution, molecular biology, geochronology, biogeochemistry, biogeology, and planetology. Some of the current missions are discussed. Other subjects in the frontier of exobiology are reviewed, such as the search for planets outside the solar system, and the possible manifestation of intelligence in those new potential environments. The SETI research effort is well represented in this general overview of exobiology. This book is the proceedings of the Fifth Trieste Conference on Chemical Evolution that took place in September 1997. The volume is dedicated to the memory of Nobel Laureate Abdus Salam who suggested the initiation of the Trieste conferences on chemical evolution and the origin of life. Audience: Graduate students and researchers in the many areas of basic, earth, and life sciences that contribute to the study of chemical evolution and the origin, evolution and distribution of life in the universe.

Available in PDF, EPUB and Kindle. Book excerpt: This is an edited record of the dialogue of eminent scientists attending the fourth conference in the series of the origins of life, supported by a grant from the Biosciences Program of the National Aeronautics and Space Admini stration. The first conference at Princeton, 1967, was held under the direc tion of Dr. Frank Fremont-Smith at the time when the Interdisciplinary Co m munications Program (lCP) was associated with the New York Academy of Sciences. In 1968, ICP was integrated into the Office of the Assistant Secretary for Science of the Smithsonian Institution, and the entire operation was set up in Washington, D. C. The second conference, also in Princeton, was held in 1968 and the third was in Santa Ynez, California in 1970. (See Margulis, ed. 1970, 1971 and 1972 for previously published proceedings.) The fourth conference was held at the Belmont Conference Center in Elkridge, Maryland, April 13-16, 1971. The proceedings are recorded and edited by the Interdisciplinary Com munications Associates, Inc. (lCA, a nonprofit foundation), for ICP. Dr. Lynn Margulis, who served as Scientific Editor for the entire series, has succeeded admirably in carrying out a difficult and usually inadequately appreciated task. She was ably assisted in her offices by Barbara Miranda and Harriet Eklund, the ICP Staff Editor for this series. I am grateful to all.
