There seem to be so many potentially fertile research pathways for this topic. It makes one wonder if there are multiple chemical pathways towards the first biochemistry, or if all but one of these will turn out to be dead ends.
Or if several partial pathways need to interact in specific ways.

"..."RNA is so perfect today that it has to be the product of evolution," says Nicholas Hud..."
Indeed, the first replicators must have been dirty, 'noisy' form the point of view of information and therefore not made of RNA or DNA. Fossils of them may be hidden somewhere on or under the surface of the moon. Finding leftover of terrestrian impactors of that period, 4-3.8 billion years, should be a major research endeavor for future lunar scientists (or robots most likely).
