Life from an RNA World by Michael Yarus Pdf

A majority of evolutionary biologists believe that we now can envision our biological predecessors--not the first, but nearly the first, living beings on Earth. This book is about these vanished forebears. The era between the first rudimentary life on Earth and the appearance of more complex beings is called the RNA world. It is RNA (ribonucleic acid) long believed to be a mere biologic copier and messenger, that offers a glimpse into our ancient predecessors. To describe early RNA creatures, here called "ribocytes" or RNA cells, the author uses basics of molecular biology. He reviews our current understanding of the tree of life, examines the structure of RNA itself, explains the operation of the genetic code, and more. Courting controversy among those who question the role of ribocytes -- citing the chemical fragility of RNA and the uncertainty about the origin of an RNA synthetic apparatus -- he offers a vision of early life on Earth.

Life's Greatest Secret by Matthew Cobb Pdf

Life's Greatest Secret is the story of the discovery and cracking of the genetic code. This great scientific breakthrough has had far-reaching consequences for how we understand ourselves and our place in the natural world. The code forms the most striking proof of Darwin's hypothesis that all organisms are related, holds tremendous promise for improving human well-being, and has transformed the way we think about life. Matthew Cobb interweaves science, biography and anecdote in a book that mixes remarkable insights, theoretical dead-ends and ingenious experiments with the pace of a thriller. He describes cooperation and competition among some of the twentieth century's most outstanding and eccentric minds, moves between biology, physics and chemistry, and shows the part played by computing and cybernetics. The story spans the globe, from Cambridge MA to Cambridge UK, New York to Paris, London to Moscow. It is both thrilling science and a fascinating story about how science is done.

The Origin of Life on the Earth by A. I. Oparin,A. E. Braunshteĭn,A. G. Pasynskiĭ Pdf

The Origin of Life on the Earth covers the proceedings of the First International Symposium of The Origin of Life on the Earth, held at Moscow on August 19-24, 1957. This symposium brings together numerous scientific studies on the evolutionary principles and the different stages in the evolutionary development of matter. This book is organized into seven parts encompassing 60 chapters. The first parts discuss evidence that on the formation of hydrocarbons and their derivatives on the surface of the Earth even before the emergence of life. The subsequent parts are devoted to the many asymmetrical syntheses under the influence of circularly-polarized ultraviolet light, by catalytic reactions occurring on the surface of quartz crystals, and spontaneously by slow crystallization from solutions. These topics are followed by reviews on the possible means of abiogenic formation of amino acids, porphyrins, protein-like polymers, polynucleotides and other high-molecular organic compounds. Considerable chapters explore the complete possibility of the primary formation of these compounds on the surface of the Earth even before life was present on it. Other general topics covered include nucleic acids, nucleoproteins and viruses. The last part considers general biochemical problems connected with the further development of metabolism. This book will be of value to astronomers, physicists, geologists, chemists, and biologists.

Clay Minerals and the Origin of Life by Alexander Graham Cairns-Smith Pdf

This volume is the edited proceedings of a conference seeking to clarify the possible role of clays in the origin of life on Earth. At the heart of the problem of the origin of life lie fundamental questions such as: What kind of properties is a model of a primitive living system required to exhibit and what would its most plausible chemical and molecular makeup be? Answers to these questions have traditionally been sought in terms of properties that are held to be common to all contemporary organisms. However, there are a number of different ideas both on the nature and on the evolutionary priority of 'common vital properties', notably those based on protoplasmic, biochemical and genetic theories of life. This is therefore the first area for consideration in this volume and the contributors then examine to what extent the properties of clay match those required by the substance which acted as the template for life.

The First Cell by Ulrich C. Schreiber,Christian Mayer Pdf

This book introduces a fresh perspective on the conditions for the genesis of the first cell. An important possible environment of the prehistoric Earth has long been overlooked as a host to the perfect biochemical conditions for this process. The first complexes of continental crust on the early Earth must have already contained systems of interconnected cracks and cavities, which were filled with volatiles like water, carbon dioxide and nitrogen. This book offers insights into how these conditions may have provided the ideal physical and chemical setting for the formation of protocells and early stages of life. The authors support their hypothesis with a number of astonishing findings from laboratory experiments focusing on a variety of organic compounds, and on the formation of key cellular ingredients and of primitive cell-like structures. Moreover, they discuss the principles of prebiotic evolution regarding the aspects of order and complexity. Guiding readers through various stages of hypotheses and re-created evolutionary processes, the book is enriched with personal remarks and experiences throughout, reflecting the authors' personal quest to solve the mystery surrounding the first cell.

Why Does Evolution Matter? by Gabriel Trueba Pdf

Evolution is not merely a chapter in biology textbooks; rather, it is the mesh that embraces and connects every biological phenomenon; indeed, as Dobzhansky pointed out, nothing in biology could be understood without the evolutionary logic. The contents of this book highlight the importance of evolution in applied biological sciences such as agricultural, medical, environmental and the social sciences. Evolutionary science provides renewed ideas which can result in practical applications and tools that deal with current problems concerning humanity, such as disease, food production, and environmental destruction. Most of the topics in this book were discussed during the III Summit on Evolution which took place in the Galapagos Islands in June 2013, hosted by the Galapagos Institute for the Arts and Sciences and the Galapagos Science Institute, Universidad San Francisco de Quito.

The Major Transitions in Evolution by John Maynard Smith,Eörs Szathmáry Pdf

During evolution there have been several major changes in the way genetic information is organized and transmitted from one generation to the next. These transitions include the origin of life itself, the first eukaryotic cells, reproduction by sexual means, the appearance of multicellular plants and animals, the emergence of cooperation and of animal societies. This is the first book to discuss all these major transitions and their implications for our understanding of evolution.Clearly written and illustrated with many original diagrams, this book will be welcomed by students and researchers in the fields of evolutionary biology, ecology, and genetics.

The RNA World by Raymond F. Gesteland,Thomas Cech,John F. Atkins Pdf

Recent studies on the activities of RNA in the cell have revolutionized our understanding of the many roles played by this molecule. The first two editions of The RNA World(1993, 1999) shed light on the pre–biotic era dominated by this versatile molecule, and provided an overview of the state of RNA research at the time. The new third edition of The RNA Worldupdates this perspective, describing the vast array of newly discovered roles for RNA in the modern world. The updated original chapters are supplemented with new chapters on RNA–protein complexes, snRNPs and snoRNPs, telomerase RNA, RNAi, microRNAs, noncoding RNA, and many other subjects. This book is essential reading for anyone interested in the biology of nucleic acids and gene regulation and a valuable resource for teaching these concepts.

Gene Machine by Venki Ramakrishnan Pdf

A Nobel Prize-winning biologist tells the riveting story of his race to discover the inner workings of biology's most important molecule "Ramakrishnan's writing is so honest, lucid and engaging that I could not put this book down until I had read to the very end." -- Siddhartha Mukherjee, author of The Emperor of All Maladies and The Gene Everyone has heard of DNA. But by itself, DNA is just an inert blueprint for life. It is the ribosome -- an enormous molecular machine made up of a million atoms -- that makes DNA come to life, turning our genetic code into proteins and therefore into us. Gene Machine is an insider account of the race for the structure of the ribosome, a fundamental discovery that both advances our knowledge of all life and could lead to the development of better antibiotics against life-threatening diseases. But this is also a human story of Ramakrishnan's unlikely journey, from his first fumbling experiments in a biology lab to being the dark horse in a fierce competition with some of the world's best scientists. In the end, Gene Machine is a frank insider's account of the pursuit of high-stakes science.

The Selfish Gene by Richard Dawkins Pdf

Science need not be dull and bogged down by jargon, as Richard Dawkins proves in this entertaining look at evolution. The themes he takes up are the concepts of altruistic and selfish behaviour; the genetical definition of selfish interest; the evolution of aggressive behaviour; kinshiptheory; sex ratio theory; reciprocal altruism; deceit; and the natural selection of sex differences. 'Should be read, can be read by almost anyone. It describes with great skill a new face of the theory of evolution.' W.D. Hamilton, Science
