| Abstract | [Introduction]
The notion of a biologically determined link between input and output of an animal’s communication system is a commonplace of ethology. Seventy years ago Huxley (1914) remarked that the courtship rituals of the great-crested grebe must have evolved by selection of perceptually salient patterns from the bird’s repertoire of motorically possible gestures. More recently, behavioral geneticists have sought evidence of perceptuomotor genetic coupling in breeding studies of crickets and grasshoppers. The conclusion from several such studies over the past ten years is that generating and perceiving mechanisms are polygenically determined and mutually adapted, but not genetically coupled (Barlow, 1981). |
