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.

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 question...it will be a landmark for discussion for a long time to come." — New York Times.

Life appears ungraspable, yet its understanding lies at the heart of current preoccupations. In our attempt to understand life through its origins, the ambition of the present collection is to unravel the network of the origin of the various spheres of sense that carry it onwards. The primogenital matrix of generation (Tymieniecka), elaborated as the fulcrum of this collection, elucidates the main riddles of the scientific / philosophical controversies concerning the status of various spheres that seek to make sense of life.

Origins of Life on the Earth and in the Cosmos, Second Edition, suggests answers to the age-old questions of how life arose in the universe and how it might arise elsewhere. This thorough revision of a very successful text describes key events in the evolution of living systems, starting with the creation of an environment suitable for the origins of life. Whereas one may never be able to reconstruct the precise pathway that led to the origin of life on earth, one can certainly make some plausible reconstructions of it. Such discussions have greatly expanded our understanding of the principles of chemical evolution and how they compare and contrast with the principles of biological evolution. The text is strong on biochemistry and its recent applications to origins' research. Provides an excellent review of basic biochemistry an evolution Written in a clear, concise style for scientists, students, and readers interested in a scientific inquiry into the origins of life Written by an authority in the field, and brought fully up-to-date in light of new research Pulls together valuable information not found in a single source Organized and presented in a manner conductive for use in a college course Heavily illustrated to make difficult concepts concrete

These are exciting times for exobiology. The ubiquity of organic molecules in interstellar clouds, comets and asteroids strongly supports a cosmic perspective on the origin of life. Data from both ground-based telescopes and the recently launched Infrared Space Observatory are providing new insight into the complexity of carbon-based chemistry beyond the Earth. Meteorites give us solid evidence for extraterrestrial amino acids, and putative fossil evidence for life in a 3.6 billion-year-old Martian meteorite hints that life in our system might not be the sole prerogative of the Earth. Giant planets have now been discovered orbiting other stars, and although such planets seem unlikely to be habitable themselves, their existence strongly suggests what many astronomers have long believed - that planetary systems are commonplace. All these topics are reviewed in this volume by active researchers. The level is appropriate for graduate students in astronomy, biology, chemistry, earth sciences, physics, and related disciplines. It will also provide a valuable source of reference for active researchers in these fields.

In this fascinating book, John Maynard Smith and Eors Szathmary present an original picture of evolution. They propose that during evolution there have been a number of major transitions in the way in which information is passed between generations. These transitions include the appearance of the first replicating molecules, the emergence of co-operative animal societies, and the unique language ability of humans. Containing many new ideas, this book is contemporary biology on the grandest scale, from the birth of life to the origin of language.

The Origins of Life and the Universe is the culmination of a university science professor's search for understanding and is based on his experiences teaching the fundamental issues of physics, chemistry, and biology in the classroom. What is life? Where did it come from? How can understanding the origins of life on Earth help us understand the origins of the universe, and vice versa? These are questions that have occupied us all. This is a book, then, about the beginning of things—of the universe, matter, stars, and planetary systems, and finally, of life itself—topics of profound interest that are rarely considered together. After surveying prescientific accounts of the origins of life, the book examines the concepts of modern physics and cosmology, in particular the two pillars of modern physics, relativity and quantum theory, and how they can be applied to the Big Bang model of the creation of the universe. The author then considers molecular genetics and DNA, the famed building block of life. In addition to assessing various hypotheses concerning the appearance of the first bacterial cells and their evolution into more complex eukaryotic cells, this section explains how "protocells" may have started a kind of integrated metabolism and how horizontal gene transfer may have speeded up evolution. Finally, the book discusses the possibility that life did not originate on planet Earth but first appeared on other solar planets, or perhaps in other star systems. How would such a possibility affect our understanding of the meaning of life, or of its ultimate fate in the universe? The book ends as it begins, with profound questions and penetrating answers, a state-of-the-art guide to unlocking the scientific mysteries of life and matter.
