The theory that language evolved from manual gestures, termed Gestural Theory, dates back to the work of 18th-century philosopher and priest Abbé de Condillac, and has been revived by contemporary anthropologist Gordon W. Hewes, in 1973, as part of a discussion on the origin of language. [4]
The gestural theory states that speech was a relatively late development, evolving by degrees from a system that was originally gestural. Human ancestors were unable to control their vocalisation at the time when gestures were used to communicate; however, as they slowly began to control their vocalisations, spoken language began to evolve.
Gesture recognition is an area of research and development in computer science and language technology concerned with the recognition and interpretation of human gestures. A subdiscipline of computer vision, [citation needed] it employs mathematical algorithms to interpret gestures. [1]

[1] Language is important because it is the means by which an individual may convey his attitudes and assume the roles of others, and thus participate in the ...

In semiotics , meaningless components of spoken gestures (written as individual letters), or meaningless components of sign language gestures (such as location of hand ...

[6] For example, pointing through the extension of a body part, especially the index finger to indicate interest in an object is a widely used gesture that is understood by many cultures [7] On the other hand, manual signs are conventionalized—they are gestures that have become a lexical element ...

The origin of language, its relationship with human evolution, and its consequences have been subjects of study for centuries.Scholars wishing to study the origins of language draw inferences from evidence such as the fossil record, archaeological evidence, contemporary language diversity, studies of language acquisition, and comparisons between human language and systems of animal ...
