Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The field of planetary biology and chemical evolution draws together experts in astronomy, paleobiology, biochemistry, and space science who work together to understand the evolution of living systems. This field has made exciting discoveries that shed light on how organic compounds came together to form self-replicating molecules-the origin of life. This volume updates that progress and offers recommendations on research programs-including an ambitious effort centered on Mars-to advance the field over the next 10 to 15 years. The book presents a wide range of data and research results on these and other issues: The biogenic elements and their interaction in the interstellar clouds and in solar nebulae. Early planetary environments and the conditions that lead to the origin of life. The evolution of cellular and multicellular life. The search for life outside the solar system. This volume will become required reading for anyone involved in the search for life's beginnings-including exobiologists, geoscientists, planetary scientists, and U.S. space and science policymakers.

Available in PDF, EPUB and Kindle. Book excerpt: How did life emerge on Earth? Is there life on other worlds? These questions, until recently confined to the pages of speculative essays and tabloid headlines, are now the subject of legitimate scientific research. This book presents a unique perspective--a combined historical, scientific, and philosophical analysis, which does justice to the complex nature of the subject. The book's first part offers an overview of the main ideas on the origin of life as they developed from antiquity until the twentieth century. The second, more detailed part of the book examines contemporary theories and major debates within the origin-of-life scientific community. Topics include: Aristotle and the Greek atomists' conceptions of the organism Alexander Oparin and J.B.S. Haldane's 1920s breakthrough papers Possible life on Mars?

Available in PDF, EPUB and Kindle. Book excerpt: RNA plays a central, and until recently, somewhat underestimated role in the genetics underlying all forms of life on earth. This versatile molecule not only plays a crucial part in the synthesis of proteins from a DNA template, but is also intrinsically involved in the regulation of gene expression, and can even act as a catalyst in the form of a ribozyme. This latter property has led to the hypothesis that RNA - rather than DNA - could have played an essential part in the origin of life itself. This landmark text provides a systematic overview of the exciting and rapidly moving field of RNA biology. Key pioneering experiments, which provided the underlying evidence for what we now know, are described throughout, while the relevance of the subject to human disease is highlighted via frequent boxes. For the second edition of Molecular Biology of RNA, more introductory material has been incorporated at the beginning of the text, to aid students studying the subject for the first time. Throughout the text, new material has been included - particularly in relation to RNA binding domains, non-coding RNAs, and the connection between RNA biology and epigenetics. Finally, a new closing chapter discusses how exciting new technologies are being used to explore current topical areas of research.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
