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 pri

An understanding of the conditions that allowed life to emerge and exist on our planet is essential if we are to answer two fundamental questions facing humanity - the continuation of life on earth, and the existence of life outside our planet. This text contributes to our understanding of astrobiology as it applies to planet Earth.

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.

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.

Astrobiology is an expanding, interdisciplinary field investigating the origin, evolution and future of life in the universe. Tackling many of the foundational debates of the subject, from discussions of cosmological evolution to detailed reviews of common concepts such as the 'Rare Earth' hypothesis, this volume is the first systematic survey of the philosophical aspects and conundrums in the study of cosmic life. The author's exploration of the increasing number of cross-over problems highlights the relationship between astrobiology and cosmology and presents some of the challenges of multidisciplinary study. Modern physical theories dealing with the multiverse add a further dimension to the debate. With a selection of beautifully presented illustrations and a strong emphasis on constructing a unified methodology across disciplines, this book will appeal to graduate students and specialists who seek to rectify the fragmented nature of current astrobiological endeavour, as well as curious astrophysicists, biologists and SETI enthusiasts.

Our world is nested, both physically and socially, and at each level we find innovations that are necessary for the next. Consider: atoms combine to form molecules, molecules combine to form single-celled organisms; when people come together, they build societies. Physics has gone far in mapping the basic mechanics of the simplest things and the dynamics of the overall nesting, as have biology and the social sciences for their fields. But what can we say about this beautifully complex whole? How does one stage shape another, and what can we learn about human existence through understanding an enlarged field of creation and being?In Quarks to Culture, Tyler Volk answers these questions, revealing how a universal natural rhythm-building from smaller things into larger, more complex things-resulted in a grand sequence of twelve fundamental levels across the realms of physics, biology, and culture. He introduces the key concept of "combogenesis," the building-up from combination and integration to produce new things with innovative relations. He explores common themes in how physics and chemistry led to biological evolution, and biological evolution to cultural evolution. Volk also provides insights into linkages across the sciences and fields of scholarship, and presents an exciting synthesis of ideas along a sequence of things and relations, from physical to living to cultural. The resulting inclusive natural philosophy brings clarity to our place in the world, offering a roadmap for those who seek to understand big history and wrestle with questions of how we came to be.
