Evolutionary Tradeoffs between Economy and Effectiveness in Biological Homeostasis Systems

Figure 1

In nature, the parameters that determine the dynamics of a circuit may fill the parameter space uniformly or, instead, lie in a confined manifold within parameter space.

(a) A schematic diagram of a circuit whose parameters, and (b) determine the dynamics (c) of the internal variable (, red) and the output (, blue) for a given input time series (, green). Two schematic illustrations of possible scenarios that could exist in nature are (d) the occurrences of the circuit fill parameter space or (e) the occurrences of the circuit are confined to a curve or manifold in parameter space. Natural selection in the context of tradeoffs can effectively remove points from (d), resulting in (e).
