Talking Animal

A talking animal or speaking animal refers to any non-human animal which can produce sounds (or gestures) resembling those of a human language. Many species or groups of animals have developed forms of Animal Communication Systems (ACS) which to some appear to be a verbal language. These are not defined as language in the human sense—they lack grammar, syntax, recursion, and displacement. Studies in animal cognition have been successful in teaching some animals speech or sign, similar to sign language, but not defined as such. In the case of Koko the gorilla, for example, Koko was unable to break away from the here-and-now (displacement) in her signs. This among others represent various hallmarks of human language that Koko and similar animals have been unable to achieve.
