The members of the committee responsible for the report were chosen for theirspecial competences andwith regard for appropriate balance. This report has been reviewed by a group other than the authors according to the procedures approved by a Report Review Committee consisting of members of the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine. The National Research Council wasestablished by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy's purposes of furthering knowledge and of advising the federal government. The Council operates in accordance with general policies determined by the Academy under the au thority of its Congressional charter of 1863, which establishes the Academy as a private, nonprofit, self-governingmembership corporation. The Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in the conduct of their services to the government, the public, and the scientific and engineering communities. It is administered jointly by both Academies and the Institute of Medicine. The National Academy of Engineering and the Institute of Medicine were established in 1964 and 1970, respectively, under the charter of the National Academy of Sciences.

Origin and Evolution of Life: Implications for the Planets, a Scientific Strategy for the 1980's Foreword Thisdocument is one of a series prepared by committees of the Space Science Board (SSB) that developstrategies for space science over the period of a dec ade. Several reports in this series have been completed. Report on Space Sci ence 1975 (Part II, Report of the Committee on Planetary and Lunar Explor ation, which covers the outer planets); Strategy for Exploration of the Inner Planets: 1977-1987; A Strategy for Space Astronomy and Astrophygjcs for the 1980's {1979); Life beyond the Earth's Environment: The Biology of Living Organisms in Space {1979); Solar-System SpacePhygjcs in the 1980's: A Research Strategy {1980); Strategy for the Exploration of Primitive Solar System Bodies-Asteroids, Comets, and Meteoroids: 1980-1990 {1980); and Strategy for Space Research in Gravitational Phygjcs in the 1980's {1981). This document describes the emerging science of life as a planetary phe nomenon. It assesses the status of our knowledge of the origin of life on Earth and of the precursers of life elsewhere in the Galaxy. It also outlines ways in which we can use the capacity that space technology provides to study the biological processes that are important on a global scale in shaping the surface of the Earth and the composition of the atmosphere. The science of global biology is in its infancy, and much will have to be learned before the data are in hand to carry out defmitive global studies. This report identifies some of the questions that must be answered before these data can be effectively gathered and intelligently analyzed. The promises of global biology are great, and the challenges that must be met to realize these promises are substantial. The next decade holds the promise of seeing signifi cant progress in meeting these challenges. v Copyright National Academy of Sciences. All rights reserved. Origin and Evolution of Life: Implications for the Planets, a Scientific Strategy for the 1980's vi FOREWORD The report of the Committee on Planetary Biology and Chemical Evolu tion was approved by the Board at its meeting of October 1980. The Board appreciates the efforts of the Committee and particularly its Chairman,Lynn Margulis, who devoted a substantial amount of her time over the past two years to bringing the report to its present state.

Origin and Evolution of Life: Implications for the Planets, a Scientific Strategy for the 1980's Preface The capability to look at the earth as a whole has been developed only recent ly. The space program, both by making us aware of the unity and uniqueness of the surface of the Earth (perhaps most clearly seen in the photographs of Earth taken by the astronauts on the moon) and by providing the technology to study the entire Earth from artificial satellites, has been a primary force in the beginnings of planetary biology. Space technology has also permitted comparative studies of planetary atmospheres and surfaces. These studies coupled with the growing awareness of the effects life has had on the entire Earth are opening new lines of inquiry in science. Diverse government agencies have responsibilities related to various aspects of Earth and its atmosphere. At present, no single agency is responsible for the quality and direction of the scientific research for the investigation of the Earth viewed as a planet-that is, as a unified interacting system. Our major recommendations focus on the need for coordinationof researchon the global level. Accordingly, many of our recommendations call for interaction be tween components of the scientific community and the NationalAeronautics and Space Administration. They involve requests for cooperation, informa tion, and mutual education so that satellitebome measuring devices may be most effectively applied to the understanding of Earth's surface processes. Interactions of several scientific disciplines, including chemistry, biology, geology, and atmospheric science, must occur in order that our understanding develops. No single discipline is adequate to the task. Although this report deals with work in the established field of chemical evolution (the nonbiological production of compounds in the universe pre requisite to the origins of life), we are attempting to point the way toward a vii Copyright National Academy of Sciences.

The goals of plane tary biology, which include discerning the effects life has had on the atmo sphere, hydrosphere, and lithosphere, are complex. The application of space technology to planetary biological analysis will be a difficult task . Thus we have only outlined herea courseof action (Chapter 3, Planetary Biology). We expect that a major future task will be to formulate specific scientific ques tions in this new fieldand to determine priorities for the research needed. Copyright National Academy of Sciences.
