【正文】 Dai, 2008) Another Possibility of Language InnatenessA school of scholars hold the view that humans acquire language because of their general intelligence rather than special mental faculties for language. This view is popular in the field of cognitive linguistics since 1990s. Endowed with the general intelligence to solve puzzles and learn things, humans can learn and acplish almost anything within the capability of human (Sampson, 1980:178). To speak is just one of these activities human can learn. What should be pointed out and noted is that no special knowledge of language is preprogrammed in mind doesn’t mean language is not innate since to acquire or learn a language requires a series of innate capacity.2. DiscussionsIn this paper, instead of making judges on the two former mentioned views on the innateness of language or trying to determine which is right or better, the author intends to find proofs on the basis of former studies by scholars throughout the world to support the notion that a genetic basis is necessary for human to acquire language regardless the disputes over what is exactly innate. Biological EvidenceAs Jean Aitchison points out, “if an animal is innately programmed for some type of behavior, then there are likely to be biological clues” (Aitchison, 2000: 47). Birds can fly because they have wings. Similarly, human can talk may have its correspondent biological features as well. Therefore, numerous studies have been conducted, especially studies on aphasia and lateralization of human brain, in order to find the biological evidence for innate language capacity. Thus through close observation and experiment, it has been proved true that human vocal tract and brain have a number of slightly unusual features.First, human teeth are unusual pared with those of other animals. They are even in height, and form an unbroken barrier. They are evenly spaced and equalsized, making the articulation of a number of sounds possible and easier. Second, human lips have muscles which are considerably more developed and show more intricate interlacing than those in the lips of other primates and thus provides great favor for the articulation of a number of sounds. Third, human mouth is relatively small, and can be opened and shut rapidly. This makes it simple to pronounce sounds such as P and B, which requires a total stoppage of the airstream. Fourth, human tongue is thick, muscular and mobile which makes the articulation of a range of vowels possible. Fifth, human larynx is much simpler in structure than that of other primates which makes air move more freely through mouth and nose without much difficulty. (Aitchison, 2000: 48) Sixth, the human brainbody weight ratio is much greater than other animals and thus suggests that human brain is different from that of other animals. Further observations depending on patients with aphasia prove that there are certain specific areas in human brain involved in speech planning, prehension and articulation of language (Mackay et al. 1987). Animals Can Never Learn LanguageDuring the past decades, several attempts have been made to teach language to chimpanzees in USA. Not even one chimpanzee could successfully learn language as humans do. Such results and findings suggest that the capacity of acquiring language is innately programmed in human brain.Through continuous observation and exploration into the animal munication systems and human language, linguists have obtained an agreement that language is unique to human and animals cannot naturally talk. But the question whether animals can learn to talk or learn language soon arose, and led to several attempts to teach language to animals. Some birds like parrots can only imitate the sounds or sound strings of human without knowing the meanings, and thus c
