Since that time, amino acids seem to be on the forefront of prebiotic molecule research, which includes the study of DNA, RNA, proteinoids (Sidney Fox), ribozymes (Thomas Cech & Sidney Airman), and pre-RNA molecules such as peptide nucleic acid (Peter E.
Then we can consult numerous works showing how the spontaneous origin of proteinoids and amphoteric substances (layers and micelles of surface active liquid crystalline precursors of cell membranes) can have taken place, within which the autocatalytic cycles became protected.
The aggregation of proteinoids [3] into microspheres under the hydrophobic tension of an aqueous environment also created entropy at the expense of free energy.
