An honest man, armed with all the knowledge available to us now, could only state that in some sense, the origin of life appears at the moment to be almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.

Protein synthesis is a central problem for the whole of biology, and that it is in all probability closely related to gene action.
