We introduce the notion of an “adaptive growth process” in order to explain an experimental result from the 1950s in which a complex mechanism capable of distinguishing between two sounds emerges from a homogeneous chemical solution. We present a very simple computational model which exhibits an adaptive growth process. Adaptive growth processes could have practical applications in adaptive control systems and may also play a role in biological development.
