"A self-organising electronic circuit has stunned engineers by turning itself into a radio receiver. What should have been an oscillator became a radio What should have been an oscillator became a radio.
"This accidental reinvention of the radio followed an experiment to see if an automated design process, that uses an evolutionary computer program, could be used to "breed" an electronic circuit called an oscillator. An oscillator produces a repetitive electronic signal, usually in the form of a sine wave." [more, New Scientist, so will disappear in a week]
