Prebiotic Selection Induced by Periodic Starlight

Conference paper


We consider the transition of the prebiotic polymeric soup into a chemically differentiated and space structured material, this being a crucial step in the origin of animate matter when suitable elements become abundant on the earth. We suggest that Stochastic Resonance (SR) must have been a mechanism by which the periodic warming of the earth’s surface may have assisted this transition, by promoting and thus selecting those pathways with reaction time close to earth rotation period. Several points of general relevance to chemical evolution are briefly discussed. This proposal can be tested in the laboratory.
