ORIGIN OF LIFE

The concept of hot dilute soup was proposed by

J B S Haldane in 1929 visualized oceans as hot dilute soup rich in organic molecules formed under reducing atmosphere with energy from lightning and ultraviolet radiation. This metaphor explained concentration of monomers enabling polymerization and coacervate formation as proposed by Oparin. The idea framed prebiotic chemistry as accumulating in aqueous reservoirs rather than dry land. Later Miller-Urey experiments supported feasibility. Recognizing Haldane's contribution links Haldane to conceptual origin of chemical evolution preceding cellular life. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype
