These equations are described by linked non-linear reactions. Or, in other words, it is a result of reactions of second order. A hypercycle differs fundamentally from cyclic processes. Strictly speaking, it describes a chain of reactions that have to be depicted as a screw, since it does symbolize both a growth function and a control circuit with feedback. Both features are causally related, feedback being most likely the most important prerequisite of self-amplifying effects.
Little causes can thus elicit huge effects.
Model of a hypercycle of the second order. It has already been mentioned that all living systems can be characterized as open systems existing in a far from stable equilibrium dependent on a constant supply of energy. Molecules and thus also molecules carrying information have thus only a limited life time and a constant new synthesis is necessary to maintain a certain information. Both the rate of production and the rate of decay are not constant but are subject to more or less strong fluctuations. A system has consequently only a chance to survive, if the rate of synthesis is fundamentally higher than the maximal amplitude of decay.
