Chemical Evolution--self-organization of the Macromolecules of Life: Proceedings of the Trieste Conference on Chemical Evolution and the Origin of Life, 25-29 October 1993Julián Chela Flores The contents record evidence of early life from the oldest known fossil in the geological record, as well as the prior events of chemical evolution & self-organization; the question of the chirality of protein amino acids is discussed. The book is organized in five sections corresponding to chemical, geological, biochemical, & biophysical aspects of self-organization, concluding with a section on chirality. It provides an excellent introduction to this ever-growing interdisciplinary area of research in chemistry, physics, & the life sciences. This volume is a FESTSCHRIFT for the late PROFESSOR CYRIL PONNAMPERUMA in whose honor the Second Trieste Conference was held, & contains the papers presented at the Conference. |
