RNA世界假说的多个前提得到了证实,这带来了一个鲜为人知的结果,那就是我们现在对生命起源之后的黎明生物有所了解,可能是40多亿年前。因此,我们处于一个更好的位置,可以在RNA时代之前,在第一个复制因子,地球上第一个达尔文生物的时代,对生物群进行推理。在现代生物学中仍然很突出的一种RNA同源物似乎是这些第一复制因子的后代。
A little-noted result of the confirmation of multiple premises of the RNA-world hypothesis is that we now know something about the dawn organisms that followed the origin of life, perhaps over 4 billion years ago. We are therefore in an improved position to reason about the biota just before RNA times, during the era of the first replicators, the first Darwinian creatures on Earth. An RNA congener still prominent in modern biology is a plausible descendent of these first replicators.
