Download or read book Abiogenesis and Life from Dirt written by Andrew Crosse and published by Book Shed. This book was released on 2015-04-22 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the original experiment by Andrew Crosse in the 19th century, along with a successful replication of his experiment by the London Electrical Society: In the year of 1837 Andrew Crosse endeavored to create synthetic crystal formations with silicates, water, and electricity. A couple weeks into the experiment, Crosse saw tiny crystal nucleations. Success, he thought. But, in the weeks to come he would notice something revolutionary. These crystal formations were developing the exact anatomy of an insect from the genus acarus! Eventually, these insect mineralizations dislodged from their rocky birthplace and began moving around. They even responded to external stimulus, such as light, implying that they developed some sort of sensory ability. When Crosse shared his results with the local community, an outrage ensued. "Only God can create" yelled the angry community. Ironically, Crosse had given evidence that life could be created from dirt, thus supporting the notion of creationism. Even more interesting, the initial conditions in Crosse's experiment are similar to those in Genesis; earth, water, and electricity: 1. The earth (Genesis 1:1) is comprised of about 70% silicates in its crust. 2. Water (Genesis 1:2). 3. Electricity is implied when light becomes present (Genesis 1:3), because light is electromagnetic radiation. Electricity is a form of electromagnetic radiation. Crosse demonstrated that life can arise from ways we have yet to understand through modern science. Many laugh and say his experiment was simply infested with the ova of the described insect. Crosse discusses his various methods of aseptic technique which insist that this was not the case. Even more convincing, his experiment was successfully recreated by William H Weekes of the London Electrical Society. Both Crosse's and Weekes' full experiment are contained within this book. Weekes' recreation took further precautions in ensuring that there was no biological infestation occuring. Regardless of any implications regarding the creation of life, this is a truly amazing experiment that deserves to be known by every person seeking answers to life's grandest questions. Many will wonder why more people don't know about this. My best guess is because it is inexplicable. It is as if life is encoded in electricity, or rather, light.
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.
Download or read book Origin of Life via Archaea written by Richard Gordon and published by John Wiley & Sons. This book was released on 2024-10-01 with total page 1268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book surveys the models for the origin of life and presents a new model starting with shaped droplets and ending with life as polygonal Archaea; it collects the most published micrographs of Archaea (discovered only in 1977), which support this conclusion, and thus provides the first visual survey of Archaea. Origin of Life via Archaea’s purpose is to add a new hypothesis on what are called “shaped droplets”, as the starting point, for flat, polygonal Archaea, supporting the Vesicles First hypothesis. The book contains over 6000 distinct references and micrographs of 440 extant species of Archaea, 41% of which exhibit polygonal phenotypes. It surveys the intellectual battleground of the many ideas of the origin of life on earth, chemical equilibrium, autocatalysis, and biotic polymers. This book contains 17 chapters, some coauthored, on a wide range of topics on the origin of life, including Archaea’s origin, patterns, and species. It shows how various aspects of the origin of life may have occurred at chemical equilibrium, not requiring an energy source, contrary to the general assumption. For the reader’s value, its compendium of Archaea micrographs might also serve many other interesting questions about Archaea. One chapter presents a theory for the shape of flat, polygonal Archaea in terms of the energetics at the surface, edges and corners of the S-layer. Another shows how membrane peptides may have originated. The book also includes a large table of most extant Archaea, that is searchable in the electronic version. It ends with a chapter on problems needing further research. Audience This book will be used by astrobiologists, origin of life biologists, physicists of small systems, geologists, biochemists, theoretical and vesicle chemists.

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 Self And The Phenomenon Of Life A Biologist Examines Life From Molecules To Humanity written by Ramon Lim and published by #N/A. This book was released on 2017-07-20 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'As an innovative treatment of scientific topics with philosophical undertones, this is an impressive work, Some may not be convinced by the arguments, but for scientists and philosophers alike the author presents a thesis worth exploring.'CHOICEThe book describes a common ground between the biology of life and the humanity of life without compromising either discipline. It attempts to bridge the gap between our 'two cultures' — the sciences and the humanities, as advocated by C P Snow fifty years ago. This book connects our meager existence to the entire living world and the universe, physically and spiritually, through the simple perspective of 'self,' being defined as a system that seeks its own perpetuation.
Download or read book Origin of Life written by and published by . This book was released on 2018-09-15 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abiogenesis, or informally the origin of life, is the natural process by which life arises from non-living matter, such as simple organic compounds. The transition from non-living to living entities was not a single event, but a gradual process of increasing complexity. Researchers study abiogenesis through a combination of molecular biology, paleontology, astrobiology and biochemistry, and aim to determine how pre-life chemical reactions gave rise to life. The study of abiogenesis can be geophysical, chemical, or biological, with more recent approaches attempting a synthesis of all three, as life arose under conditions that are strikingly different from those on Earth today. Life functions through the specialized chemistry of carbon and water and builds largely upon four key families of chemicals: lipids (fatty cell walls), carbohydrates (sugars, cellulose), amino acids (protein metabolism), and nucleic acids (self-replicating DNA and RNA). Any successful theory of abiogenesis must explain the origins and interactions of these classes of molecules. Many approaches to abiogenesis investigate how self-replicating molecules, or their components, came into existence. Researchers generally think that current life on Earth descends from an RNA world, although RNA-based life may not have been the first life to have existed. This book is a compilation of high quality articles from the Internet.

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.
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
