"A self-organising electronic circuit has stunned engineers by turning itself into a radio reciever. This accidental reinvention of the radio followed an experiment to see if an automated design process, that uses an evolutionary computer programm, could be used to "breed" an electronic circuit called an oscillator. But when they looked more closely they found, despite producing an oscillating signal, the circuit itself was not actually an oscillator. Instead, it was behaving more like a radio reciever, picking up signal from a nearby computer and delivering it as an output"
