Kricheldorf H. Life by Chemical Evolution. A Review and Evaluation...2025

Textbook in PDF format This book provides an in-depth analysis of the hypothesis of chemical evolution that may have led to the origin of life, serving three main purposes: it provides a comprehensive summary of hundreds of chemical experiments and analytical studies from the past 70 years, evaluates their significance in supporting the hypothesis of chemical evolution, and offers a critical review of these experiments and hypotheses. The book is particularly valuable for students, postdocs, and scientists engaged in experimental work in this field. Introduction Hypotheses and Birthplaces of the Chemical Evolution The Polycondensation Processes of the Chemical Evolution Model Syntheses of Amino Acids Model Syntheses of Saccharides, Nucleobases, Nucleosides, and Nucleotides Model Syntheses of Oligo- and Polypeptides Model Syntheses of Oligo- and Polynucleotides Copolymerization, Self-Reproduction, and Genetic Code The Message from Space The Problem of Homochirality Summary and Conclusions
