The article states: "One possible mechanism would have concentrated the sea water in a lagoon by evaporation until the amino acids were partially precipitated, and then synthesized peptides with the precipitated amino acids." I understand that the 5- and 6-carbon amino acids would precipitate first, but why do they (or any other amino acids) need to be precipitated for synthesis of a polypeptide? Does this not occur if they are in solution?
