One of my favorites is the phospholipid bilayer. It is the beginning of the protective environment necessary for RNA replication to avoid the ravages of the 2nd Law of Thermodynamics, to play a sort of "Maxwell's Demon" role (stretching terms a bit) in the advancement of the system of molecules. Experiments with the early stages of RNA replication typically avoid using a phospholipid bilayer.
Perhaps among the reasons are that although the conditions to develop a phospholipid bilayer are easily set up in a lab, and the conditions to get a set of amino acids are easily set up in a lab, trying to do both at once proves to be most difficult. How do you get not just amino acids but the beginnings of chains of RNA to form inside the phospholipid bilayer? Then you have another problem. Although you've reduced the agencies of disassembly, you've also reduced the agencies of forward assembly. If the chains were sitting there doing nothing before, they're even more determined to do nothing now. The great philosophical question then becomes which came first, the long "smart" RNA chain or the phospholipid bilayer?
The most likely way life began is from short strands of RNA building longer ones. In the lab however they don't get longer than about 40 links (last I checked). That's because the shorter strands have the competitive advantage and will break apart the longer ones, unwittingly of course. In that case "natural selection" is preventing the progress of life, or rather the progress of nonliving things toward life.
By the way your links have nothing significant to add. Very short RNA chains self replicate rather successfully and this has been known for decades.
