The book is particularly valuable for students, postdocs, and scientists engaged in experimental work in this field. This book outlines the latest experimental and theoretical achievements in chemical evolution research, addressing fundamental questions such as ?How to define life?? and ?Why life by chemical evolution??. It explores various hypotheses and covers topics like polymerization processes, model syntheses of amino acids, saccharides, and nucleotides, and the chemistry of interstellar clouds and meteorites. In this book, readers will discover a thorough examination of the problem of homochirality and its implications for the origin of life. The book also invites readers to think through critical questions such as the likelihood of life emerging elsewhere in the universe and the role of race­mization in early biochemical processes. This volume is an essential resource for researchers and scholars in biochemistry, as­trobiology, and evolutionary biology, as well as students and interested laypersons. Offering valuable insights into the chemical foundations of life, this book appeals to all who are curious about how life began. 606 $aBiomaterials 606 $aNucleic acids 606 $aPolymers 606 $aProteins 606 $aExobiology 606 $aEvolution (Biology) 606 $aNucleic Acid 606 $aPolymers 606 $aProtein Biochemistry 606 $aAstrobiology 606 $aEvolutionary Biology 615 0$aBiomaterials. 615 0$aNucleic acids. 615 0$aPolymers. 615 0$aProteins. 615 0$aExobiology. 615 0$aEvolution (Biology) 615 14$aNucleic Acid. 615 24$aPolymers. 615 24$aProtein Biochemistry. 615 24$aAstrobiology. 615 24$aEvolutionary Biology. 676 $a620.19 676 $a547.7 700 $aKricheldorf$b Hans R$4aut$4http://id.loc.gov/vocabulary/relators/aut$0854282 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911010532403321 996 $aLife by Chemical Evolution$94403727 997 $aUNINA
