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 (e(aq)(-)). Solvated electrons are produced in seawater, mainly by (40)K 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 e(aq)(-) 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 e(aq)(-). The presented hypothesis is mainly founded on recently obtained experimental results. The involvement of e(aq)(-) in such mechanisms, as well as their action as an initiator of life is also briefly discussed.
基于目前的知识状况，提出了一个关于地球生命起源的新假说，并强调了溶剂化电子（e(aq)(-)）的特殊意义。溶剂化电子在海水中主要由（40）K辐射产生，在大气水汽中则由真空紫外光、放电和宇宙射线产生。溶剂化电子参与初级化学过程和生物过程。在实验中已证明，在e(aq)(-)的作用下，水溶液中的二氧化碳和一氧化碳可转化为简单的有机物质，氮气和水可生成氨，还可形成胺、氨基酸和简单蛋白质。此外，由于e(aq)(-)的强还原性，推测原始细胞的产生和原始酶的平衡也得以实现。所提出的假说主要基于最近获得的实验结果。还简要讨论了e(aq)(-)在这些机制中的参与情况及其作为生命起源引发剂的作用。
