“新陈代谢先起源”和“复制先起源”假说研究进展

The progress of study on the hypothesis of " metabolism origin first" and "replication origin first"

"新陈代谢先起源"假说认为新陈代谢的出现先于(或同时)模板复制能力的出现."复制先起源"假说则认为前生物合成的有机化合物能够通过非生物自发聚合形成具有自我复制能力的遗传信息系统,并逐渐拥有了"新陈代谢"能力.针对这个"生命起源"研究中的"鸡"-"蛋"悖论所涉及的一些问题进行了系统的综述.

The hypothesis of ＆quot;metabolism origin first＆quot; is that the emergence of metabolism is in earlier （or at the same time） than replication .The hypothesis of ＆quot;replication origin first＆quot;is that pre-biosynthesis of organic compounds has the ability to form a replicate genetic information sys-tem by abiotic spontaneous aggregation ,and gradually have the ability to ＆quot;metabolism＆quot;.In this paper ,the problems involved in the “chicken first” or “eggs first” paradox in the study of “the origin of life” was reviewed systematically .
