The rate of energy flow governs anabolic processes in chemical and biological systems. When a steady flow of external energy enters into an open system, there is a driving force to assemble mechanisms from available components in order to disperse more energy in the quest for a stationary steady state . The driving force does not distinguish between mechanisms of energy transduction but favors those that disperse energy more efficiently. The mechanisms that effectively distribute energy become temporal repositories of that energy, which allows other mechanisms (i.e. energy dispersal systems) to tap into them, which further enhances energy dispersal and ultimately creates networks (Figure 1.1).
A commonplace example of this classic thermodynamic phenomenon is a hot cup ...
