7. Notice the use of the term self-reproduction instead of self-replication (Luisi, P. L. In Self-Production of Supramolecular Structures; Fleischhaker, G. R., Colonna, S., Luisi, P. L. Eds.; Kluwer Academic: Dordrecht, 1994; pp 196-197): in the latter case, we are dealing with mechanisms that determine a perfect replica of the original (usually a template); a self-reproduction process is instead dominated by statistical laws and the copying process is generally not perfect; for example, although the same kind of micelles or vesicles, respectively, are formed, the size and size distribution can be different. More generally, the difference between these two processes may be relevant from the point of view of origin of life: as noted by Dyson (Dyson, F. Origins of Life, Cambridge University Press: Cambridge, 1985), most likely the less sophisticated self-reproduction processes have preceded the exact molecular mechanisms of self-replication.

20. Please note that the preparation of the mixed micellar solution needs 2-3 days to form and equilibrate at room temperature.
21. Long time measurements indicate that a plateau is reached after about 400 min with a measured optical density at 500 nm of 0.22 (compare with curve a in Figure 1).
22. In these calculations unilamellarity and sphericity of the vesicles are assumed.

30. From the literature it is known that the binding of fatty acids to phospholipid vesicles is a rather fast process; see for example: Kleinfeld, A. M.; Chu, P.; Romero, C. Biochemistry 1997, 36, 14146-14158.
