HOW COULD MOLECULES STORE INFORMATION BEFORE LIFE EXISTED? THE CHEMICAL ORIGINS OF BIOLOGICAL INFORMATION ABSTRACT One of the most fundamental questions in science is how nonliving matter acquired the ability to store, copy, and transmit information before the emergence of life. Modern organisms depend on DNA, RNA, and proteins to maintain biological organization, reproduce, and evolve. However, these sophisticated molecular systems could not have existed in their present form before life emerged. How, then, did the first informational molecules originate, and how could chemical reactions eventually produce systems capable of Darwinian evolution? This article examines the chemical origins of biological information through prebiotic chemistry, molecular biology, information theory, evolutionary theory, and complex systems science. It explores how molecular sequences can carry structural information, how complementary base pairing supports information transfer, and how catalytic molec...

Can a Chemical Reaction Produce Order from Disorder? The Science of Self-Organization, Entropy, and Emergent Complexity Abstract The emergence of order from apparently disordered chemical systems is a fundamental problem in physical chemistry, thermodynamics, complexity science, and origin-of-life research. Although the second law of thermodynamics states that the total entropy of an isolated system cannot decrease, many chemical and physical systems develop organized structures, oscillating reactions, spatial patterns, and self-maintaining networks. These phenomena appear paradoxical only when local organization is confused with the total entropy of a system and its surroundings. Research on nonequilibrium thermodynamics demonstrates that open systems can develop ordered structures when they exchange energy and matter with their environments and operate away from thermodynamic equilibrium. Such structures, commonly described as dissipative structures, can emerge through nonlinear ch...
