In the domain of biology, organic biological systems are characterised by a state of homeostasis or "steady state". Complex adaptive systems are adaptive in nature, in that they exist in steady state and attempt to preserve steady state through adaptation. When something threatens or changes the system, thereby interrupting steady state, the system will adapt to return to steady state as quickly and efficiently as possible. When change is introduced, there is a push and pull, an ebb and flow that is a natural part of the system. Like the waters of the earth resist the pull of the moon's gravity, creating the tides, there is a natural ebb and flow to systems as part of change.
