There is Paleolithic evidence that visual-based language occurred before auditory (Stokoe, 2002). This hypothesis comes, in part, from evidence that there was linguistic communication before the voice/speech tract evolved into a form that allowed for articulated auditory communication (Laitman, 1982). The ability of a congenitally deaf person to acquire language through a ' 'non-traditional'' sensory mode, vision, was not widely appreciated or recognized until the 16th century. People should learn the American Sign Language, in this way people would develop awareness and sensitive to cultural and linguistic diversity in addition to presser the cultural identity of one.
It is not certain where the American Sign Language originated; it is true that it came to be more than 200 years ago from the unification of local sign languages and French Sign Language (LSF). Nowadays, ASL has been influenced by both LSF and local sign languages and their merge has created a deep, elaborate, and complete language. American Sign Language (ASL) is a complicated language spoken through intricate signs made by one's hands blended with a variety of facial expressions, body positions, and other gestures. .
The language is most commonly used by the deaf population in North America and is the major communication alternative for the deaf and hard-of-hearing. Since ASL is seen as an authentic and definite language, it has many variations, just like other languages do, such as French and Spanish. There is no single form of sign language that is universal because each variation of sign language is unique to its specific region. ASL is an exceptional form of communication and beneficial to an enormous part of the population. Its origin, present conditions, future expectations, and overall impact are quite extraordinary and eye opening. .
Although similar to spoken languages, sign language also significantly differs from them in a variety of forms.
