An analogy can be drawn between human language and an animals organism.They bear similarity in some respects through they belong to different planes of existance.According to revolutionary thinking in Zoology only an individual possesses real existence.Orders genera and spices in the zological world are nothing more conceptual groupings and distinctions. Likewise In language, an idiolect is the real linguistic phenomenon. Standard language, dialect is the real linguistic phenomenon. Standard language, dialect, and varieties of language are mere conceptual grouping and distinctions. In zoology, an individual is the real existence. Again, an individual animal organism develops on two fectors:heredity and environment. So does an idiolect : it is formed under the influence of the speech of members of the social group on the one hand, and the quite unrelated and unique experience of his physical and mentel life. The speech of the social group in case of language is the equivalent of parents, and in case of language the individual physical and mental experiences are an equivalent of environment. The similarities between human language and animals organism are striking.
