Abstract
Based on the present state of knowledge a new hypothesis concerning the origin of life on Earth is presented, and emphasizes the particular significance of solvated electrons (eaq−). Solvated electrons are produced in seawater, mainly by 40K radiation and in atmospheric moisture by VUV light, electrical discharges and cosmic ray. Solvated electrons are involved in primary chemical processes and in biological processes. The conversion of aqueous CO2 and CO into simple organic substances, the generation of ammonia from N2 and water, the formation of amines, amino acids and simple proteins under the action of eaq− has been experimentally proven. Furthermore, it is supposed that the generation of the primitive cell and equilibria of primitive enzymes are also realized due to the strong reducing property of eaq−. The presented hypothesis is mainly founded on recently obtained experimental results. The involvement of eaq− in such mechanisms, as well as their action as an initiator of life is also briefly discussed.
