Prebiological Evolution and the Metabolic Origins of Life

  title={Prebiological Evolution and the Metabolic Origins of Life},
  author={Andrew J. Pratt},
  journal={Artificial Life},
The chemoton model of cells posits three subsystems: metabolism, compartmentalization, and information. A specific model for the prebiological evolution of a reproducing system with rudimentary versions of these three interdependent subsystems is presented. This is based on the initial emergence and reproduction of autocatalytic networks in hydrothermal microcompartments containing iron sulfide. The driving force for life was catalysis of the dissipation of the intrinsic redox gradient of the… CONTINUE READING
