The concept of evolution has been applied, not only to biology, but to numerous other fields as well. In various disciplines, both the study of the history of technology and the history of philosophy, the concept is invoked to structure the successive changes in a technology, a concept, or the thinking of an individual philosopher over the course of his work. Selective Evolution has also been proposed as a means by which ideas propagate, spread and change (See Meme, History of philosophy, History of technology, Philosophy of science).

In general use, evolution in this context refers to theories which identify, and then connect, the discrete steps involved in the process of change from original idea, to its stable form, for example, the first telephone used a different process for converting sound into electricity than the first commercial phone, this step would be part of the telephone's evolution.

the evolution of an idea or concepts should be further analized. . . changes occur due to specifiable types of stimulus or input during the analytical process. and these changes occur along specifiable dementions. . .

types of input may include outside information supplied by another thinker external to one's mind, or the realization of a flaw on one's own due to an inherant contradiction or paradox. changes can also orrur seemingly spontaneously, during the evolution of an idea one can recieve "inspiration" from various sources that are often seeminly unspecifiable.

changes can happen to the overall way an idea is structured. one may realize that a simple rearrangement can shed light that seems to fill an invisible void. . . changes can occur to specific elements of the idea, some specific componant of a conceptual construct can sometimes be altered to be more specific or more broad. . . or even completely different without disturbing the overall structure, but changing the understanding that the pattern conveys in a beneficial or detrimental way. . .

Key thinkers in the use of evolution of ideas include Hegel, Karl Popper, Richard Dawkins and Thomas Kuhn
