Abstract
The emergence of the ribosome constituted a pivotal step in the evolution of life. This event happened nearly four billion years ago, and any traces of early stages of ribosome evolution are generally thought to have completely eroded away. Surprisingly, a detailed analysis of the structure of the modern ribosome reveals a concerted and modular scheme of its early evolution.
摘要
核糖体的出现是生命进化中的关键一步。这一事件发生在近40亿年前，人们普遍认为核糖体早期进化的任何痕迹都已完全消失。令人惊讶的是，对现代核糖体结构的详细分析揭示了其早期进化的协同和模块化模式。
