The problem is how you get the first proteins all composed of L amino acids in an environment which would have had roughly 50-50 D & L amino acids. You make the mistake of thinking that either amino acid has an equal chance in being "picked" by the special protein. There is a 50-50 chance for the first amino acid, but once it is picked then the next amino acid and all those that follow have to have the same matching "hand". There is almost no chance that a left-handed and right-handed version would be assembling at exactly the same time. One had to be first. Once one was first it would only assemble amino acids that fit into it's pattern as decide by the first acid. There were lots of other proteins forming, and some were right and some were left, but only one was the "first" to have the correct characteristic to reproduce, and that made all the difference in the world. Soon there were two proteins, each of which ate only the L amino acids, then four and then many. The rest was still just soup, it wasn't a competing R-form of the same protein, it was just soup. In the mean time the L protein was not only reproducing, but it was reproducing with changes, and there lies evolution. TP
