The Concepts of Productivity and Displacement as They Are Applied to Human Language
However, there are some key differences between how humans and animals communicate. Specifically, human language is unique on the planet because it has the qualities of generativity, recursion, and displacement.
Specialisation allows humans to use words to describe a physical action without actually having to do the action, for example if we want someone to leave the room "Get out!" can be shouted without actually having to physically remove the person from the room. Each language has universal traits such as nouns and verbs. A linguist named Joseph Greenberg studied and compared 30 languages from around the world and noted that there are rules in which the way languages are governed. Greenberg states that language universals are of an important value in the study of language.
Startling though it is, the bee dance is, so far at least, absolutely unique in the non-human world: no other creatures, not even apes, can communicate anything of the sort, and even the bee dance is severely limited in its expressive powers: it cannot cope with the slightest novelty (Robert Lawrence Trask and Peter Stockwell, 2007).
But human infants growing up in isolation without any human language input cannot speak a language instinctively.
