化学进化论 - 百度百科
- 主张从物质的运动变化规律来研究生命的起源
化学进化论，即主张从物质的运动变化规律来研究生命的起源。认为在原始地球的条件下，无机物可以转变为有机物，有机物可以发展为生物大分子和多分子体系，直到最后出现原始的生命体。 - 1924年苏联学者奥巴林首先提出了这种看法；1929年英国学者霍尔丹也发表过类似的观点。他 …
化学进化论在自然科学中是指一种阐释从无机物中产生地球生命起源的理论。在米勒实验——该实验模仿了早期地球的环境，科学家发现通过与生命无关的自然化学反应能够产生被称为“生命原材料”的氨基酸。在生命体中，这些氨基酸组合成蛋白质；而蛋白质的构造则又是由核酸所决定。所 …
