Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Origins of Life written by Douglas Whittet and published by Morgan & Claypool Publishers. This book was released on 2017-12-07 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Origins of Life: A Cosmic Perspective presents an overview of the concepts, methods, and theories of astrobiology and origins of life research while presenting a summary of the latest findings. The book provides insight into the environments and processes that gave birth to life on our planet, which naturally informs our assessment of the probability that has arisen (or will arise) elsewhere. In addition, the book encourages readers to go beyond basic concepts, to explore topics in greater depth, and to engage in lively discussions.

Readers are assumed to have a basic grounding in the relevant sciences, but prior specialized knowledge is not required. Each chapter concludes with a list of questions and discussion topics as well as suggestions for further reading. Some questions can be answered with reference to material in the text, but others require further reading and some have no known answers. The intention is to encourage readers to go beyond basic concepts, to explore topics in greater depth, and, in a classroom setting, to engage in lively discussions with class members.
Download or read book Beyond the Stars written by Paolo Saraceno and published by World Scientific. This book was released on 2012-07-17 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: "What is the origin of the universe? Are we alone in the Universe?" Using clear and plain language, the author explores these two interesting scientific-philosophical themes with a broad range of studies, including astronomy, cosmology, chemistry, biology, geology and planet science. The first part discusses the origins of everything, from the Big Bang to humankind. It follows the long course of evolution — from original matter to the formation of more complex structures, from the furthest galaxies to the nearest stars, from planets to organic molecules, from the first and most elementary forms of life through to the reptiles, the dinosaurs and the advent of man. The second part traces the history of the Earth and evaluates the risks of extinction in the future as predicted by scientists. Is the Earth the only habitable planet in the Universe? This question initiates the discussion on the importance of the Earth's position in the solar system and the significance of our geologically alive planet. The final part is dedicated to the search for extraterrestrial beings with identifiable life forms. It also describes attempts for searching, from the past to the near future. This remarkable book provides the best answers we have to the epic questions about us and our place in the universe.

Download or read book Exploring the Origin Extent and Future of Life written by Constance M. Bertka and published by Cambridge University Press. This book was released on 2009-09-03 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where did we come from? Are we alone? Where are we going? These are the questions that define the field of astrobiology. New discoveries about life on Earth, the increasing numbers of extrasolar planets being identified, and the technologies being developed to locate and characterize Earth-like planets around other stars are continually challenging our views of nature and our connection to the rest of the universe. In this book, philosophers, historians, ethicists, and theologians provide the perspectives of their fields on the research and discoveries of astrobiology. A valuable resource for graduate students and researchers, the book provides an introduction to astrobiology, and explores subjects such as the implications of current origin of life research, the possible discovery of extraterrestrial microbial life, and the possibility of altering the environment of Mars.
Download or read book The Genesis Quest written by Michael Marshall and published by University of Chicago Press. This book was released on 2020-11-20 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the primordial soup to meteorite impact zones, the Manhattan Project to the latest research, this book is the first full history of the scientists who strive to explain the genesis of life. How did life begin? Why are we here? These are some of the most profound questions we can ask. For almost a century, a small band of eccentric scientists has struggled to answer these questions and explain one of the greatest mysteries of all: how and why life began on Earth. There are many different proposals, and each idea has attracted passionate believers who promote it with an almost religious fervor, as well as detractors who reject it with equal passion. But the quest to unravel life’s genesis is not just a story of big ideas. It is also a compelling human story, rich in personalities, conflicts, and surprising twists and turns. Along the way, the journey takes in some of the greatest discoveries in modern biology, from evolution and cells to DNA and life’s family tree. It is also a search whose end may finally be in sight. In The Genesis Quest, Michael Marshall shows how the quest to understand life’s beginning is also a journey to discover the true nature of life, and by extension our place in the universe.

Download or read book Life s Origin written by J. William Schopf and published by Univ of California Press. This book was released on 2002-10-21 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Always a controversial and compelling topic, the origin of life on Earth was considered taboo as an area of inquiry for science as recently as the 1950s. Since then, however, scientists working in this area have made remarkable progress, and an overall picture of how life emerged is coming more clearly into focus. We now know, for example, that the story of life's origin begins not on Earth, but in the interiors of distant stars. This book brings a summary of current research and ideas on life's origin to a wide audience. The contributors, all of whom received the Oparin/Urey Gold Medal of the International Society for the Study of the Origin of Life, are luminaries in the fields of chemistry, paleobiology, and astrobiology, and in these chapters they discuss their life's work: understanding the what, when, and how of the early evolution of life on Earth. Presented in nontechnical language and including a useful glossary of scientific terms, Life's Origin gives a state-of-the-art encapsulation of the fascinating work now being done by scientists as they begin to characterize life as a natural outcome of the evolution of cosmic matter.

Download or read book Astronomical Origins of Life written by B. Hoyle and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Living material contains about twenty different sorts of atom combined into a set of relatively simple molecules. Astrobiologists tend to believe that abiotic mater ial will give rise to life in any place where these molecules exist in appreciable abundances and where physical conditions approximate to those occurring here on Earth. We think this popular view is wrong, for it is not the existence of the building blocks of life that is crucial but the exceedingly complicated structures in which they are arranged in living forms. The probability of arriving at biologically significant arrangements is so very small that only by calling on the resources of the whole universe does there seem to be any possibility of life originating, a conclusion that requires life on the Earth to be a minute component of a universal system. Some think that the hugely improbable transition from non-living to living mat ter can be achieved by dividing the transition into many small steps, calling on a so-called 'evolutionary' process to bridge the small steps one by one. This claim turns on semantic arguments which seek to replace the probability for the whole chain by the sum of the individual probabilities of the many steps, instead of by their product. This is an error well known to those bookies who are accustomed to taking bets on the stacking of horse races. But we did not begin our investigation from this point of view.

This book was released on 2004-02-20 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systematically explores the early origins and basic definition of life. Investigates the major theories of the origins of life in light of modern research with the aim of distinguishing between the necessary and the optional and between deterministic and random influences in the emergence of what we call ‘life.’ Treats and views life as a cosmic phenomenon whose emergence and driving force should be viewed independently from its Earth-bound natural history. Synthesizes all the fundamental life-related developments in a comprehensive scenario, and makes the argument that understanding life in its broadest context requires a material-independent perspective that identifies its essential fingerprints
Download or read book Origins of Life written by Geoffrey Zubay and published by Elsevier. This book was released on 2000-01-18 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
