First of all there is a problem which is seldom discussed. The starting monomers would have been grossly impure. On the basis of Simulation experiments they would have been present in complex mixtures that contained a great variety of variously reactive molecules. N0 sensible organic chemist would hope to get much out of a reaction from starting materials that were tars containing the reactants as minor constituents.
Amino acids are not formed as easily as Lee et al. claim. If they form at all, they are extremely dilute and impure, as well as racemic (50–50 mix of left and right-handed forms). 1
