Human language is entirely different from animal communication. Human language has many properties which makes it different from animal communication. Human language has alphabets which help man to write down and preserve ideas for coming generations. Animal communication is context bound, they cannot communicate any experience of past. Animal communication is biologically transmitted thus it cannot learn any other languages. Some birds like parrot may imitate human utterances but it reiterate the words without knowing meaning also fails to learn more words. If they try to learn new utterance the older ones get erased. Whereas human beings can imitate the sounds of animals and make them respond to the sounds easily. Hence human communication or human language is a unique one which is the sole property of him.
