Beschreibung
This book provides a comprehensive treatment of the chemical nature of the Earth’s early surface environment and how that led to the origin of life,including a detailed discussion of the likely process by which life emerged using as much quantitative information as possible. The emergence of life and the prior surface conditions of the Earth have implications for the evolution of Earth’s surface environment over the following 2-2.5 billion years. The last part of the book discusses how these changes took place and the evidence from the geologic record that supports this particular version of early and evolving conditions.

Addresses the issue of Earth’s early surface and its relationship to the origin of life more comprehensively, and to some extent more quantitatively than has been done to date Provides arguments for adopting a view of the early Earth’s surface significantly different from conventional wisdom Expands on a model for the emergence of life proposed by Eigen and De Duve using quantitative treatment of molecular biologic components, a novel approach which underpins the likelihood that life would arise with a much higher probability than previously thought Combines molecular biology insights with geological reasoning of conditions and environments on the early Earth Examines the geologic evidence in support of the presented model Includes supplementary material: sn.pub/extras
