RNA world - Wikipedia
The RNA world is a hypothetical stage in the evolutionary history of life on Earth in which self-replicating RNA molecules proliferated before the evolution of DNA and proteins. [1] The term also refers to the hypothesis that posits the existence of this stage.

Time line for the universe, suggesting the early existence of an RNA world of living systems. In this section we outline some of the arguments in support of the RNA world hypothesis.
RNA world学说 （RNA world hypothesis） - 知乎专栏
科学家们普遍认为非生命的化学物质（non-living chemicals）不可能通过单一的步骤产生单细胞生命，所以一定存在着中间体-细胞前的生命形式（intermediate, pre-cellular life forms），而在细胞前的生命形式中，最受欢迎的就是RNA World。

1986年，随着多种RNA核酶催化活性的发现，Walter Gilbert首次提出了“the RNA world”的假说 。他设想了一个原始的、只含有RNA的世界：RNA分子催化自我复制，通过自我剪接产生具有功能活性的RNA分子，通过内含子形成的转座元件不断重排以适应不同环境。
The RNA World: molecular cooperation at the origins of life
2014年11月11日 · The RNA World concept is the idea that billions of years ago — before current life based on DNA, RNA and proteins — the primary living substance was RNA or something chemically similar.
The RNA world ‘hypothesis’ - Nature Reviews Molecular Cell Biology
2022年7月6日 · The RNA world hypothesis — which postulates that RNA with both genetic information and catalytic activity had an essential role in the origin of life — is now supported by many scientists.
RNA world - Khan Academy
The RNA world hypothesis suggests that life on Earth began with a simple RNA molecule that could copy itself without help from other molecules. DNA, RNA, and proteins are central to life on Earth. DNA stores the instructions for building living things—from bacteria to bumble bees.

The general notion of an “RNA World” is that, in the early development of life on the Earth, genetic continuity was assured by the replication of RNA and genetically encoded proteins were not involved as catalysts.
