That doesn't make sense unless there was some kind of competition in space to select for the chemicals to cause then to evolve to RNA.
How could they evolve into RNA on Earth?
Was there a simpler replicator first?
If so, what was it?
No, the question is how could they not evolve ?. What possible mechanism would be used instead of the process of natural selection ? The alternatives presented to date are just plain silly. So thus there was a simpler replicator and the job is now to find it.
I suspect we won't see it around much today any more than we see scaffolding around buildings except when they are under construction.
Am I then correct in taking this as there was a simpler replicator, but we have no clue as to what it was?
