Astrobiology: An Evolutionary Approach is an interdisciplinary textbook that presents astrobiology as a dynamic, developing science of the utmost importance for the future of humanity. Featuring contributions from leaders in physics, chemistry, astronomy, biology, molecular biology, ecology, planetary science, geography, and geology, the book discusses the evolution of abiotic matter to biotic matter and emphasizes new discoveries in prebiotic chemistry, such as solid-state (solventless), in/on-water, and multicomponent reactions. It describes the most challenging problems involved in the field of astrobiology and invites the reader to become actively involved in their solution. Look for the chapter titled "Transition from Abiotic to Biotic: Is There an Algorithm for It?" contributed by Prof. Walker!
