Silicon makes organic compounds? that's a new one on me.silicon, for example, makes many of the same organic compounds as carbon, and one could at least imagine a silicon based life-form.)

It was Gods first blunder.God did it
Silicon is actually a very poor comparison when it comes to the array of compounds of carbon.

Ok fair enough---I was just giving an example. I did think, though, that many of the organic compounds that are fundamental to life had analogues with carbons replaced by all or some silicons?
Is man one of God's blunders? Or is God one of man's blunders?
Current thinking has it developing from RNA. Which raises the question of hwo the RNA evolved. A couple of researchers haev proposed that the original coding was from crystals. Cairns-Smith favours clay minerals - which can get pretty complex; someone else (who? who?) favours pyrites - which is good because it can tie in with developing primitive metabolisms.How did DNA come into existence?
