Available in PDF, EPUB and Kindle. Book excerpt: The Evolutionary Science of Extraterrestrial Life approaches the evolution of simple, complex and intelligent life forms and technological cultures, anywhere in the universe, from a perspective that is independent of any particular environment, whether that environment is the rocky surface of inner planets like Earth or Mars, the atmosphere of a giant gas planet like Jupiter, moons like our own, or Saturn's Titan, or a gaseous nebula. A series of questions must here be asked. What could such a science tell us about simple life forms, about complex, about intelligent life forms and technological civilizations? What physical, social and psychological characteristics would an intelligent life form have irregardless of how or where it evolved? What are the choke points any environment must challenge and defeat if simple life forms are to evolve into complex forms or complex into intelligent forms? Once intelligent life evolves, how inevitable is its rise to technology? What lies beyond technology as genetic and cyborg frontiers are invaded? Most approaches to these questions involve probabilities in the spirit of the Drake equation or get tangled in the specifics of Earthlike environments, the search for water or the specifics of human evolution. Evolutionary Science simply bypasses such discussions. It is a science one applies to an environment - any environment. Evolutionary Science proposes a series of nine, fundamental scientific principles, based solidly on physics, biological evolution and a precise definition of intelligence. Four new Imperatives are proposed that not only discipline but revolutionize any approach to defining the psychological profile of intelligent life. Thebook concludes with the implications this new science has for a number of critical issues - the nature of Life, Artificial Intelligence, biochemistries, the potential for contact, a Galactic Society - and the God factor.
Download or read book Convergent Evolution on Earth written by George R. McGhee, Jr. and published by MIT Press. This book was released on 2019-10-15 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of patterns of convergent evolution on Earth that suggests where we might look for similar convergent forms on other planets. Why does a sea lily look like a palm tree? And why is a sea lily called a “lily” when it is a marine animal and not a plant? Many marine animals bear a noticeable similarity in form to land-dwelling plants. And yet these marine animal forms evolved in the oceans first; land plants independently and convergently evolved similar forms much later in geologic time. In this book, George McGhee analyzes patterns of convergent evolution on Earth and argues that these patterns offer lessons for the search for life elsewhere in the universe. Our Earth is a water world; 71 percent of the earth's surface is covered by water. The fossil record shows that multicellular life on dry land is a new phenomenon; for the vast majority of the earth's history—3,500 million years of its 4,560 million years of existence—complex life existed only in the oceans. Explaining that convergent biological evolution occurs because of limited evolutionary pathways, McGhee examines examples of convergent evolution in forms of feeding, immobility and mobility, defense, and organ systems. McGhee suggests that the patterns of convergent evolution that we see in our own water world indicate the potential for similar convergent forms in other water worlds. We should search for extraterrestrial life on water worlds, and for technological life on water worlds with continental landmasses.
Download or read book What Does a Martian Look Like written by Jack Cohen and published by Turner Publishing Company. This book was released on 2007-08-17 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A fascinating and useful handbook to both the science and science fiction of extraterrestrial life. Cohen and Stewart are amusing, opinionated, and expert guides. I found it a terrific and informative piece of work-nothing else like it!" -Greg Bear "I loved it." -Larry Niven "Ever wonder about what aliens could be like? The world authority is Jack Cohen, a professional biologist who has thought long and hard about the vast realm of possibilities. This is an engaging, swiftly moving study of alien biology, a subject with bounds and constraints these authors plumb with verve and intelligence." -Gregory Benford "A celebration of life off Earth. A hearteningly optimistic book, giving a much-needed antidote to the pessimism of astrobiologists who maintain that we are alone in the universe-a stance based on a very narrow view of what could constitute life. A triumph of speculative nonfiction." -Dougal Dixon, author of After Man: A Zoology of the Future
Download or read book The Biological Universe written by Steven J. Dick and published by Cambridge University Press. This book was released on 1999-12-28 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the twentieth century, from the furor over Percival Lowell's claim of canals on Mars to the sophisticated Search for Extraterrestrial Intelligence, otherworldly life has often intrigued and occasionally consumed science and the public. Does 'biological law' reign throughout the universe? Are there other histories, religions, and philosophies outside of those on Earth? Do extraterrestrial minds ponder the mysteries of the universe? The attempts to answer these often asked questions form one of the most interesting chapters in the history of science and culture, and The Biological Universe is the first book to provide a rich and colorful history of those attempts during the twentieth century. Covering a broad range of topics, including the search for life in the solar system, the origins of life, UFOs, and aliens in science fiction, Steven J. Dick shows how the concept of extraterrestrial intelligence is a world view of its own, a 'biophysical cosmology' that seeks confirmation no less than physical views of the universe.

Download or read book The History and Philosophy of Astrobiology written by David Dunér and published by Cambridge Scholars Publishing. This book was released on 2013-09-26 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human beings have wondered about the stars since the dawn of the species. Does life exist out there – intelligent life, even – or are we alone? The quest for life in the universe touches on fundamental hopes and fears. It touches on the essence of what it means to formulate a theory, grasp a concept, and have an imagination. This book traces the history of the science of this area and the development of new schools in philosophy. Its essays seek to establish the history and philosophy of astrobiology as research fields in their own right by addressing cognitive, linguistic, epistemological, ethical, cultural, societal, and historical perspectives on astrobiology. The book is divided into three sections. The first (Cognition) focuses on the human mind and what it contributes to the search for life. It explores the emergence and evolution of terrestrial life and cognition and the challenges humans face as they reach to the stars. The essays raise philosophical questions, pose ethical dilemmas, and offer a variety of approaches, including one from cognitive zoology, in formulating a theory of the universal principles of intelligence, the limits of human conceptual abilities, and the human mind’s encounter with the unknown. The second section (Communication) examines the linguistic and semiotic requirements for interstellar communication. What is needed for successful communication? Are there universal rules for success? What are the possible features – and limitations – of exolanguages? What is required for recognizing a message as a message? The third section (Culture) considers cultural and societal issues. It explores astrobiology’s organization as a scientific discipline, its responsibilities to the public sphere, and its theological implications. It reviews the historically important panspermia hypothesis, along with the popularization of astrobiology and its ongoing institutionalisation. Through addressing these questions, we take our first steps in exploring the immense terra incognita of extraterrestrial life and the human mind.
Download or read book The Zoologist s Guide to the Galaxy written by Arik Kershenbaum and published by Penguin. This book was released on 2022-03-15 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wildly fun and scientifically sound exploration of what alien life must be like Scientists are confident that life exists elsewhere in the universe. Yet rather than taking a realistic approach to what aliens might be like, we imagine that life on other planets is the stuff of science fiction. The time has come to abandon our fantasies of space invaders and movie monsters and place our expectations on solid scientific footing. Using his own expert understanding of life on Earth and Darwin's theory of evolution--which applies throughout the universe--Cambridge zoologist Dr. Arik Kershenbaum explains what alien life must be like: how these creatures will move, socialize, and communicate. Might there be an alien planet with supersonic animals? A moon where creatures have a language composed of smells? Will aliens scream with fear, act honestly, or have technology? The Zoologist's Guide to the Galaxy answers these questions using the latest science to tell the story of how life really works, on Earth and in space.

Download or read book Science Society and the Search for Life in the Universe written by Bruce M. Jakosky and published by University of Arizona Press. This book was released on 2022-10-18 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Are we alone in the universe? As humans, are we unique or are we part of a greater cosmic existence? What is life’s future on Earth and beyond? How does life begin and develop? These are age-old questions that have inspired wonder and controversy ever since the first people looked up into the sky. With today’s technology, however, we are closer than ever to finding the answers. Astrobiology is the relatively new, but fast growing scientific discipline that involves trying to understand the origin, evolution, and distribution of life within the universe. It is also one of the few scientific disciplines that attracts the public’s intense curiosity and attention. This interest stems largely from the deep personal meaning that the possible existence of extraterrestrial life has for so many. Whether this meaning relates to addressing the “Big Questions” of our existence, the possibility of encountering life on other planets, or the potential impact on our understanding of religion, there is no doubt that the public is firmly vested in finding answers. In this broadly accessible introduction to the field, Bruce Jakosky looks at the search for life in the universe not only from a scientific perspective, but also from a distinctly social one. In lucid and engaging prose, he addresses topics including the contradiction between the public’s fascination and the meager dialogue that exists between those within the scientific community and those outside of it, and what has become some of the most impassioned political wrangling ever seen in government science funding.

Download or read book Extraterrestrial Altruism written by Douglas A. Vakoch and published by Springer Science & Business Media. This book was released on 2013-09-14 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extraterrestrial Altruism examines a basic assumption of the Search for Extraterrestrial Intelligence (SETI): that extraterrestrials will be transmitting messages to us for our benefit. This question of whether extraterrestrials will be altruistic has become increasingly important in recent years as SETI scientists have begun contemplating transmissions from Earth to make contact. Technological civilizations that transmit signals for the benefit of others, but with no immediate gain for themselves, certainly seem to be altruistic. But does this make biological sense? Should we expect altruism to evolve throughout the cosmos, or is this only wishful thinking? Is it dangerous to send messages to other worlds, as Stephen Hawking has suggested, or might humankind benefit from an exchange with intelligence elsewhere in the galaxy? Would extraterrestrial societies be based on different ethical principles, or would we see commonalities with Earthly notions of morality? Extraterrestrial Altruism explores these and related questions about the motivations of civilizations beyond Earth, providing new insights that are critical for SETI. Chapters are authored by leading scholars from diverse disciplines—anthropology, astronomy, biology, chemistry, computer science, cosmology, engineering, history of science, law, philosophy, psychology, public policy, and sociology. The book is carefully edited by Douglas Vakoch, Director of Interstellar Message Composition at the SETI Institute and professor of clinical psychology at the California Institute of Integral Studies. The Foreword is by Frank Drake. This interdisciplinary book will benefit everybody trying to understand whether evolution and ethics are unique to Earth, or whether they are built into the fabric of the universe.
Download or read book Evolving the Alien written by Jack Cohen and published by Vintage. This book was released on 2002 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: What would life on other planets look like? Forget the little green men, alien life is likely to be completely unrecognisable -we haven't even discovered all the life on our own planet. This visionary book offers some of the most radical but scientifically accurate thinking on the possibility of life on other planets ever conceived. Using broad principles of Earthly biology and expanding on them laterally, Cohen and Stewart examine what could be out there. Redefining our whole concept of what 'life' is, they ask whether aliens could live on the surface of a star, in the vacuum of space or beneath the ice of a frozen moon. And whether life could exist without carbon or DNA -or even without matter at all. They also look at 'celebrity aliens' from books and films -most of which are biologically impossible. Jack Cohen is an 'alien consultant' to many writers, advising what an alien could and couldn't look like. (E. T. go home -you do not pass the test). But this book is as much about the latest discoveries in Earthly biology as well as life on other planets. It's a serious yet entertaining science book, as you'd expect from the bestselling authors of THE SCIENCE OF DISCWORLD.
Download or read book Beyond UFOs written by Jeffrey O. Bennett and published by Princeton University Press. This book was released on 2008 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes the startling discoveries being made in the very real science of astrobiology, an intriguing new field that blends astronomy, biology, and geology to explore the possibility of life on other planets. Jeffrey Bennett takes readers beyond UFOs to discuss some of the tantalizing questions astrobiologists grapple with every day: What is life and how does it begin? What makes a planet or moon habitable? Is there life on Mars or elsewhere in the solar system? How can life be recognized on distant worlds? Is it likely to be microbial, more biologically complex--or even intelligent? What would such a discovery mean for life here on Earth?--From publisher description.
Download or read book Here Be Dragons written by David W. Koerner and published by Oxford University Press. This book was released on 2001-11-15 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of life on other planets would be perhaps the most momentous revelation in human history, more disorienting and more profound than either the Copernican or Darwinian revolutions, which knocked the earth from the center of the universe and humankind from its position of lofty self-regard. In Here Be Dragons, astronomer David Koerner and neurobiologist Simon LeVay offer a scientifically compelling and colorful account of the search for life beyond Earth. The authors survey the work of biologists, cosmologists, computer theorists, NASA engineers, SETI researchers, roboticists, and UFO enthusiasts and debunkers as they attempt to answer the greatest remaining question facing humankind: Are we alone? From their "safe haven of skepticism" the authors venture into the "rough seas of speculation," where theory and evidence run the gamut from hard science to hocus pocus. Arguing that the universe is spectacularly suited for the evolution of living creatures, Koerner and LeVay give us ringside seats at the great debates of Big Science. The contenitous arguments about what really happens in evolution, the acrimonious UFO controversy, and the debate over intelligence versus artificial intelligence shed new light on the wildly divergent claims about the universe and life's place in it. The authors argue that while no direct evidence of extraterrestrial life yet exists, habitats and chemical building blocks for life abound in the universe. A wealth of new astronomical techniques and space missions may provide this evidence early in the next century. Lucidly written and scientifically rigorous, Here Be Dragons presents everything we know thus far about the emergence of intelligent life here on earth and, perhaps, beyond.
Download or read book The New Science of Astrobiology written by Julian Chela-Flores and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astrobiology is a very broad interdisciplinary field covering the origin, evolution, distribution, and destiny of life in the universe, as well as the design and implementation of missions for solar system exploration. A review covering its complete spectrum has been missing at a level accessible even to the non-specialist. The last section of the book consists of a supplement, including a glossary, notes, and tables, which represent highly condensed `windows' into research ranging from basic sciences to earth and life sciences, as well as the humanities. These additions should make The New Science of Astrobiology accessible to a wide readership: scientists, humanists, and the general reader will have an opportunity to participate in one of the most rewarding activities of contemporary culture.
Download or read book Evo SETI written by Claudio Maccone and published by Springer Nature. This book was released on 2021-02-26 with total page 878 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a vision of how evolutionary life processes can be modelled. It presents a mathematical description that can be used not only for the full evolution of life on Earth from RNA to modern human societies, but also the possible evolution of life on exoplanets, thus leading to SETI, the current Search for ExtraTerrestrial Intelligence. The main premise underlying this mathematical theory is that the Geometric Brownian Motion (GBM) can be applied as a key stochastic process to model the evolution of life. In the resulting Evo-SETI Theory, the life of any living thing (a cell, an animal, a human, a civilization of humans, or even an ET civilization) is represented by a b-lognormal, i.e., a lognormal probability density function starting at a precise instant (b, birth) then increasing up to a peak time, then decreasing to senility time and then continuing as a straight line down to the time of death. Using this theory, Claudio Maccone arrives at remarkable hypotheses on the development of life and civilizations, the possibility of extraterrestrial life, and when computers will take over the reins from us humans (Singularity). The book develops the mathematical Evo-SETI Theory by integrating a set of articles that the author has published in various journals on Astrobiology and Astronautical Research.
