Book Synopsis Origins, Abiogenesis and the Search for Life by : Michael Russell
Download or read book Origins, Abiogenesis and the Search for Life written by Michael Russell and published by Cosmology.com. This book was released on 2010-10 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is the origin of life? How did life begin? The question of life's origins has been asked for thousands of years and a variety of theories have been proposed. Yet, perhaps the right question has never been asked, which is, what does life do? To understand life, we must understand what it is, what it does, how it evolved from simple chemicals to self-replicating molecule, and then the questions of origins can be properly addressed. Did life begin in a deep sea thermal vent, or in an alkaline world? What were the role of viruses in kick starting life? Did life emerge from disequilibrium? What is the source of pre-genetic information? Did vesicles come first, or only after life had begun? In this text, over 20 of the world's leading scientists ask, and answer the hard questions, and in so doing may have ushered in a paradigm shift, and a scientific revolution in our understanding of the nature of life and its origins.
Book Synopsis Origins of Life How Life Began Abiogenesis, Astrobiology by : Nick Lane
Download or read book Origins of Life How Life Began Abiogenesis, Astrobiology written by Nick Lane and published by . This book was released on 2011-11 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: How Did Life Begin? There are two scientific views on the origins of life: 1) Earthly-Abiogenesis which argues life on Earth began on Earth, and 2) Extraterrestrial Abiogenesis the position of which is life has an ancestry which predates the origins of Earth, and is pervasive throughout the cosmos. Thus, both theories embrace abiogenesis" and both argue that life may have begun on innumerable planets via the same mechanisms. In this ground-breaking, revolutionary text, over 30 top scientists from around the world, explain how life began and if there is life on other worlds, in over 20 paradigm busting chapters.

Available in PDF, EPUB and Kindle. Book excerpt: "I'll begin with a challenging question: Why should anyone want to know about the origin of life? The answers will vary from one person to the next, but the simplest answer is curiosity. Anyone reading this introduction is curious because they wonder how life could have begun on the Earth, but there is more to it than that. My friend Stuart Kauffman wrote a book with the title At Home in the Universe. The title refers to a deep sense of satisfaction that comes when we begin to understand how our lives on Earth are connected to the rest of the universe. There are surprises and revelations as we discover those connections"--
Download or read book Abiogenesis written by Paul F. Kisak and published by Createspace Independent Publishing Platform. This book was released on 2016-08-12 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abiogenesis has become a maturing field of study as an alternative to the creationist or intelligent design theory of the origin of life on earth. Abiogenesis, Biopoiesis or OoL (Origins of Life), is the natural process of life arising from non-living matter, such as simple organic compounds. It is thought to have occurred on Earth between 3.8 and 4.1 billion years ago. Abiogenesis is studied through a combination of laboratory experiments and extrapolation from the characteristics of modern organisms, and aims to determine how pre-life chemical reactions gave rise to life on Earth. The study of abiogenesis involves geophysical, chemical, and biological considerations, with more recent approaches attempting a synthesis of all three. Many approaches investigate how self-replicating molecules, or their components, came into existence. It is generally thought that current life on Earth is descended from an RNA world, although RNA-based life may not have been the first life to have existed. The classic Miller-Urey experiment and similar research demonstrated that most amino acids, the basic chemical constituents of the proteins used in all living organisms, can be synthesized from inorganic compounds under conditions intended to replicate those of the early Earth. Various external sources of energy that may have triggered these reactions have been proposed, including lightning and radiation. Other approaches ("metabolism-first" hypotheses) focus on understanding how catalysis in chemical systems on the early Earth might have provided the precursor molecules necessary for self-replication. Complex organic molecules have been found in the Solar System and in interstellar space, and these molecules may have provided starting material for the development of life on Earth. The panspermia hypothesis alternatively suggests that microscopic life was distributed to the early Earth by meteoroids, asteroids and other small Solar System bodies and that life may exist throughout the Universe. Given the revised and more accurate models of "The Drake Equation" and the knowledge gained on the Tardigrade species, it is very probable that some simple form of life has been deposited on earth via asteroids, meteorites or some similar phenomena. It is speculated that the biochemistry of life may have begun shortly after the Big Bang, 13.8 billion years ago, during a habitable epoch when the age of the universe was only 10 to 17 million years. The panspermia hypothesis therefore answers questions of where, not how, life came to be; it only postulates that life may have originated in a locale outside the Earth. Currently, Earth remains the only place in the Universe observed to harbor life, and fossil evidence from the Earth supplies most studies of abiogenesis. Precambrian stromatolites were found in the Siyeh Formation of The Glacier National Park. A paper in the scientific journal "Nature" 2002 suggested that these 3.5 Ga (billion years) old geological formations contain fossilized cyanobacteriamicrobes. This suggests they are evidence of one of the earliest known life forms on Earth. The age of the Earth is about 4.54 billion years; the earliest undisputed evidence of life on Earth dates from at least 3.5 billion years ago, and possibly as early as the Eoarchean Era, after a geological crust started to solidify following the earlier molten Hadean Eon. Microbial mat fossils have been found in 3.48 billion-year-old sandstone in Western Australia. Other early physical evidence of biogenic substances includes graphite discovered in 3.7 billion-year-old metasedimentary rocks in southwestern Greenland, as well as "remains of biotic life" found in 4.1 billion-year-old rocks in Western Australia. According to one of the researchers, "If life arose relatively quickly on Earth ... then it could be common in the universe." This book discusses the various methods and Evidence for the development of life on Earth by natural means.
Download or read book The Origin of Life written by Paul Davies and published by Penguin UK. This book was released on 2006-09-28 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origins of life remains one of the great unsolved mysteries of science. Growing evidence suggests that the first organisms lived deep underground, in environments previously thought to be uninhabitable, and that microbes carried inside rocks have travelled between Earth and Mars. But the question remains: how can life spring into being from non-living chemicals? THE FIFTH MIRACLE reveals the remarkable new theories and discoveries that seem set to transform our understanding of life's role in the unfolding drama of the cosmos.
Book Synopsis Beyond the Stars by : Paolo Saraceno
Download or read book Beyond the Stars written by Paolo Saraceno and published by World Scientific. This book was released on 2012 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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." --Publisher's website.
Book Synopsis A New History of Life by : Peter Ward
Download or read book A New History of Life written by Peter Ward and published by Bloomsbury Publishing USA. This book was released on 2015-04-07 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of life on Earth is, in some form or another, known to us all--or so we think. A New History of Life offers a provocative new account, based on the latest scientific research, of how life on our planet evolved--the first major new synthesis for general readers in two decades. Charles Darwin's theories, first published more than 150 years ago, form the backbone of how we understand the history of the Earth. In reality, the currently accepted history of life on Earth is so flawed, so out of date, that it's past time we need a 'New History of Life.' In their latest book, Joe Kirschvink and Peter Ward will show that many of our most cherished beliefs about the evolution of life are wrong. Gathering and analyzing years of discoveries and research not yet widely known to the public, A New History of Life proposes a different origin of species than the one Darwin proposed, one which includes eight-foot-long centipedes, a frozen “snowball Earth”, and the seeds for life originating on Mars. Drawing on their years of experience in paleontology, biology, chemistry, and astrobiology, experts Ward and Kirschvink paint a picture of the origins life on Earth that are at once too fabulous to imagine and too familiar to dismiss--and looking forward, A New History of Life brilliantly assembles insights from some of the latest scientific research to understand how life on Earth can and might evolve far into the future.

Book Synopsis Life in the Cosmos by : Manasvi Lingam
Download or read book Life in the Cosmos written by Manasvi Lingam and published by Harvard University Press. This book was released on 2021-06-29 with total page 1089 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rigorous and scientific analysis of the myriad possibilities of life beyond our planet. ÒAre we alone in the universe?Ó This tantalizing question has captivated humanity over millennia, but seldom has it been approached rigorously. Today the search for signatures of extraterrestrial life and intelligence has become a rapidly advancing scientific endeavor. Missions to Mars, Europa, and Titan seek evidence of life. Laboratory experiments have made great strides in creating synthetic life, deepening our understanding of conditions that give rise to living entities. And on the horizon are sophisticated telescopes to detect and characterize exoplanets most likely to harbor life. Life in the Cosmos offers a thorough overview of the burgeoning field of astrobiology, including the salient methods and paradigms involved in the search for extraterrestrial life and intelligence. Manasvi Lingam and Abraham Loeb tackle three areas of interest in hunting for life Òout thereÓ: first, the pathways by which life originates and evolves; second, planetary and stellar factors that affect the habitability of worlds, with an eye on the biomarkers that may reveal the presence of microbial life; and finally, the detection of technological signals that could be indicative of intelligence. Drawing on empirical data from observations and experiments, as well as the latest theoretical and computational developments, the authors make a compelling scientific case for the search for life beyond what we can currently see. Meticulous and comprehensive, Life in the Cosmos is a master class from top researchers in astrobiology, suggesting that the answer to our age-old question is closer than ever before.
