Evolution in Hardware

Gordon Pask had, in 1958, similarly evolved a physical (electrochemical) device that responded to external stimuli (e.g. Sound of a particular frequency)
Features shared by Pask's and Bird & Layzell's work:
- They are situated in the physical world
- Consist of primitives with no fixed functional roles
- Primitives are sensitive to a wide range of environmental stimuli
