However, I find the manuscript contains a number of weaknesses: One of the main issues is that paper suffers from trying to cover too many ideas, and because of this is quite long and unfocused.
The conclusion comes back to the point about primitive Earth environment. This links to the introductory section about hydrothermal conditions etc. I agree that the question of the relationship between RNA World and the environment is important, but there is nothing in the main part of this article that addresses this question. It is only mentioned in the introduction and conclusions.
