Substantial evidence to support this theory comes from among others, the fact that the ribosome is a ribozyme, the existence of small RNA catalysts capable of high activity, and self-assembling ribozymes such as the Azoarcus ribozyme. Additional support has been provided by the directed evolution of various ribozymes and the reputed prebiotic synthesis of nucleotides and small RNA oligomers. However, it has long been challenging to show how long …
