Hi,
Out of curiosity, do we know of other molecules than RNA and DNA that have the ability to be replicators?
From what I know, DNA has evolved from RNA. Could RNA have evolved from a more simple replicator. Could life have started with a rather crappy replicator? If a simple cell reproduces 100 cells but only one has no error in his replicator, that could maybe be sufficient for a start.
