Self-reproduction of a chemical system is a widely accepted criterion for seeding life. As gleaned from the function of nowadays cells, a multicomponent chemical system must undergo homeostatic growth in which the relative concentration of each molecule in the system is preserved over growth and split cycles . It has long been reported that micelles can grow through accretion of environmental lipids or through endogenous synthesis , and can divide once they become too big and structurally unstable . Some recent studies have provided experimental demonstration of compositional homeostasis in a population of proliferating mixed micelles , but detailed evidence at the single micelle level is still lacking.
