Reciprocal adjustment process between a systems internal variations and its environment's variations.
The degree of co-variance between the system and its environment depends basically upon their acquired state of reciprocal adaptation, obtained through the accumulated action of their more or less conjugated evolution.
Thereafter, it is always possible that unprecedented environmental variations should produce:
- either a new type of adjustment in the system,
- or its destruction.
However, co-variance also may produce inverse effects.
Life deeply modified our planet's atmosphere through the geological times and did transform the earth's crust, with the shaping of calcarious rocks by marine organisms or the genesis of mineral oil.
The emergence of some superior animals, and notably of man tends to put still more in reverse the process of reciprocal adjustment. Specially man tends to take evermore initiatives aiming at wide environmental transformations. However, the environment, in turn, is starting to “retort” more and more forcefully.
The importance of the process of co-variance is likewise obvious for human systems as for example enterprises, or in macro-economy problems, or in prospective.
