Reproductive process of complex elements, by the ordering action of some of their parts on simpler elements already present in their environment.
According to J.de ROSNAY: "A peculiar form of fluctuations which plays a fundamental role in the genesis of an organized structure is the self-catalytic reaction. There is self-catalysis when products of a reaction act as a catalyzer in this same reaction. A self-catalytic reaction may lead to the emergence of a structure ordered out of an homogeneous medium. It is the case of a chain reaction which produces (by random molecular collisions) a more complex molecule capable to catalyze some stages of its own formation. The chain closes on itself and produces a positive feedback starting from simpler molecules already present in the medium and available as building blocks. The complex molecule builds itself and the process accelerates with the help of the just created products" (1975, p.227).
This process is active in the DNA and RNA chain of reproduction… and thus in the reproduction of superior organisms.
It plays also a role in the autopoietic process. Self-catalysis is an important mechanism for the emergence, multiplication and stabilization of complex systems.
