Book excerpt: Seventy years ago, Erwin Schrödinger posed a profound question: 'What is life, and how did it emerge from non-life?' This problem has puzzled biologists and physical scientists ever since. Living things are hugely complex and have unique properties, such as self-maintenance and apparently purposeful behaviour which we do not see in inert matter. So how does chemistry give rise to biology? What could have led the first replicating molecules up such a path? Now, developments in the emerging field of 'systems chemistry' are unlocking the problem. Addy Pross shows how the different kind of stability that operates among replicating molecules results in a tendency for chemical systems to become more complex and acquire the properties of life. Strikingly, he demonstrates that Darwinian evolution is the biological expression of a deeper, well-defined chemical concept: the whole story from replicating molecules to complex life is one continuous process governed by an underlying physical principle. The gulf between biology and the physical sciences is finally becoming bridged. This new edition includes an Epilogue describing developments in the concepts of fundamental forms of stability discussed in the book, and their profound implications. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.

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.

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.
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.

Book Synopsis In Search of Cell History by : Franklin M. Harold
Download or read book In Search of Cell History written by Franklin M. Harold and published by University of Chicago Press. This book was released on 2014-10-29 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive history of cell evolution “deftly discusses the definition of life” as well as cellular organization, classification and more (San Francisco Book Review). The origin of cells remains one of the most fundamental mysteries in biology, one that has spawned a large body of research and debate over the past two decades. With In Search of Cell History, Franklin M. Harold offers a comprehensive, impartial take on that research and the controversies that keep the field in turmoil. Written in accessible language and complemented by a glossary for easy reference, this book examines the relationship between cells and genes; the central role of bioenergetics in the origin of life; the status of the universal tree of life with its three stems and viral outliers; and the controversies surrounding the last universal common ancestor. Harold also discusses the evolution of cellular organization, the origin of complex cells, and the incorporation of symbiotic organelles. In Search of Cell History shows us just how far we have come in understanding cell evolution—and the evolution of life in general—and how far we still have to go. “Wonderful…A loving distillation of connections within the incredible diversity of life in the biosphere, framing one of biology’s most important remaining questions: how did life begin?”—Nature
Book Synopsis Astronomical Origins of Life by : B. Hoyle
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.

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.

Book Synopsis How Life Began by : Alexandre Meinesz
Download or read book How Life Began written by Alexandre Meinesz and published by University of Chicago Press. This book was released on 2010-02-15 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin of life is a hotly debated topic. The Christian Bible states that God created the heavens and the Earth, all in about seven days roughly six thousand years ago. This episode in Genesis departs markedly from scientific theories developed over the last two centuries which hold that life appeared on Earth about 3.5 billion years ago in the form of bacteria, followed by unicellular organisms half a millennia later. It is this version of genesis that Alexandre Meinesz explores in this engaging tale of life's origins and evolution. How Life Began elucidates three origins, or geneses, of life—bacteria, nucleated cells, and multicellular organisms—and shows how evolution has sculpted life to its current biodiversity through four main events—mutation, recombination, natural selection, and geologic cataclysm. As an ecologist who specializes in algae, the first organisms to colonize Earth, Meinesz brings a refreshingly novel voice to the history of biodiversity and emphasizes here the role of unions in organizing life. For example, the ingestion of some bacteria by other bacteria led to mitochondria that characterize animal and plant cells, and the chloroplasts of plant cells. As Meinesz charmingly recounts, life’s grandeur is a result of an evolutionary tendency toward sociality and solidarity. He suggests that it is our cohesion and collaboration that allows us to solve the environmental problems arising in the decades and centuries to come. Rooted in the science of evolution but enlivened with many illustrations from other disciplines and the arts, How Life Began intertwines the rise of bacteria and multicellular life with Vermeer’s portrait of Antoni van Leeuwenhoek, the story of Genesis and Noah, Meinesz’s son’s early experiences with Legos, and his own encounters with other scientists. All of this brings a very human and humanistic tone to Meinesz’s charismatic narrative of the three origins of life.
