Book Description
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.

Book Description
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)

Book Description
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.

Book Description
This classic of biochemistry offered the first detailed exposition of the theory that living tissue was preceded upon Earth by a long and gradual evolution of nitrogen and carbon compounds. "Easily the most scholarly authority on the question...it will be a landmark for discussion for a long time to come." — New York Times.

Book Description
It seems likely that scientists will someday discover how life can emerge on habitable planets like the early Earth and Mars. In Origin of Life: What Everyone Needs to Know®, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections. The first section addresses questions such as: Where do the atoms of life come from? How old is Earth? What was the Earth like before life began? Where does water come from? After each question is answered, there is a follow-up: How do we know? This expands the horizon of the book, explaining how scientists reach conclusions and why we can trust these answers. The second section describes how certain organic molecules can spontaneously assemble into populations of protocells that can undergo selection and evolve toward primitive living systems. Here Deamer proposes a truly novel concept that life did not begin in the ocean but instead in fresh water hot springs on volcanic land masses resembling Hawaii today. True knowledge is not just what we know, but equally important is what we don't yet know. In the third section Deamer lists the outstanding questions that must be addressed before we can finally answer a fundamental question of biology: How can life begin?

Book Description
- How did the Sun come into existence? - How was the Earth formed? - How long has Earth been the way it is now, with its combination of oceans and continents? - How do you define “life”? - How did the first life forms emerge? - What conditions made it possible for living things to evolve? All these questions are answered in this colourful textbook addressing undergraduate students in "Origins of Life" courses and the scientifically interested public. The authors take the reader on an amazing voyage through time, beginning five thousand million years ago in a cloud of interstellar dust and ending five hundred million years ago, when the living world that we see today was finally formed. A chapter on exoplanets provides an overview of the search for planets outside the solar system, especially for habitable ones. The appendix closes the book with a glossary, a bibliography of further readings and a summary of the Origins of the Earth and life in fourteen boxes.

Book Description
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 Description
The search for life in the solar system and beyond has to date been governed by a model based on what we know about life on Earth (terran life). Most of NASA's mission planning is focused on locations where liquid water is possible and emphasizes searches for structures that resemble cells in terran organisms. It is possible, however, that life exists that is based on chemical reactions that do not involve carbon compounds, that occurs in solvents other than water, or that involves oxidation-reduction reactions without oxygen gas. To assist NASA incorporate this possibility in its efforts to search for life, the NRC was asked to carry out a study to evaluate whether nonstandard biochemistry might support life in solar system and conceivable extrasolar environments, and to define areas to guide research in this area. This book presents an exploration of a limited set of hypothetical chemistries of life, a review of current knowledge concerning key questions or hypotheses about nonterran life, and suggestions for future research.
