According to the GARD model, the mutually-catalytic interactions entail a kinetic influence of the momentary composition of a growing assembly on the accretion rates of joining monomers. More explicitly, the model assumes that each lipid type may influence the kinetics of any other lipid's entry into or exit from the micelle. Thus the micellar current constituency plays a critical role in determining monomer fluxes, hence the timedependent changes of the micelle's compositional states. It provides a recursive feedback loop, which induces deviations from random accretion. Monte Carlo simulations of the GARD model reveal that this guided progression allows an approach towards compositional homeostasis and self-reproduction .
