[WhoIsDaffy]

well its not going to fit into your sentence,

but, thats what your talking about.

action-reaction - your just looking at it from the other side

reaction-action

ability (reaction) - learning (action)

its simple Newtonian physics with a quantum/universal twist (god i love the way physics explains absolutely everything!)

but im suspecting that your looking at it from a sociological point of view.
in which case you are refering to technological evolution/advancement/development

however you are talking about a system,
so its going to be a systems theory

===quoting===

A pianist cannot BE TAUGHT the art, unless someone was there to build a piano, or to tune it. However, this is merely one example of the Complex adaptive system that has lead to technological advances in humanity,

===meh===

is that what your looking for? (its a fairly broad term so should fit the bill)

in biology it would fall into the camp of Developmental Psychobiology

thats why i am curious as to the tittle of your essay
