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.

Studying the origin of life is one of man’s greatest achievements over the last sixty years. The fields of interest encompassed by this quest are multiple and interdisciplinary: chemistry, physics, biology, biochemistry, mathematics, geology but also statistics, atmospheric science, meteorology, oceanography, and astrophysics. Recent scientific discoveries, such as water on Mars and the existence of super-Earths with atmospheres similar to primordial Earth, have pushed researchers to simulate prebiotic conditions in explaining the abiotic formation of molecules essential to life. This collection of articles offers an overview of recent discoveries in the field of prebiotic chemistry of biomolecules, their formation and selection, and the evolution of complex chemical systems.

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.

In Controversy, Trevor Palmer fully documents how traditional gradualistic views of biological and geographic evolution are giving way to a catastrophism that credits cataclysmic events, such as meteorite impacts, for the rapid bursts and abrupt transitions observed in the fossil record. According to the catastrophists, new species do not evolve gradually; they proliferate following sudden mass extinctions. Placing this major change of perspective within the context of a range of ancient debates, Palmer discusses such topics as the history of the solar system, present-day extraterrestrial threats to earth, hominid evolution, and the fossil record.

The Evolution of Metabolic Function presents comprehensive discussions on a variety of topics that will interest scientists and students studying the evolution of enzyme activities, the evolution of enzymatic pathways, and the evolution and development of metabolic functions. Laboratory experiments designed to develop new enzyme activities and new metabolic pathways are discussed. The most recent techniques comparing protein and gene structures are used to analyze and discuss the evolution and development of such metabolic functions as the bacterial phosphoenolpyruvate:sugar phosphotransferase system, the mandelate pathway of microorganisms, bacterial alcohol metabolism, and certain microbial amino acid biosynthetic pathways. The book also includes some unique speculations regarding the origin of early Archaean cells and the prebiotic evolution of complex molecules.

This edition of Science and Creationism summarizes key aspects of several of the most important lines of evidence supporting evolution. It describes some of the positions taken by advocates of creation science and presents an analysis of these claims. This document lays out for a broader audience the case against presenting religious concepts in science classes. The document covers the origin of the universe, Earth, and life; evidence supporting biological evolution; and human evolution. (Contains 31 references.) (CCM)

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life’s connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds. Deamer argues that life began as systems of molecules that assembled into membrane-bound packages. These in turn provided an essential compartment in which more complex molecules assumed new functions required for the origin of life and the beginning of evolution. Deamer takes us from the vivid and unpromising chaos of the Earth four billion years ago up to the present and his own laboratory, where he contemplates the prospects for generating synthetic life. Engaging and accessible, First Life describes the scientific story of astrobiology while presenting a fascinating hypothesis to explain the origin of life.
