Combination of Ribozymes with Peptides: The Evolving RNA Peptide World
It seems obvious that the scenarios described so far fail to explain the origin of cells and the existence of viruses. Therefore, to advance a step further toward these goals, one assumes that the aforementioned scenarios had to overlap with each other. This is feasible when the different niches that each contained one of the world scenarios had the opportunity to interact with each other. It is likely that Nature played with all the possible combinations.
