Primate Use of Sign Language
Sign language and computer keyboards are used in primate language research because non-human primate vocal cords cannot close fully, and they have less control of the tongue and lower jaw. However, primates do possess the manual dexterity required for keyboard operation.
Many researchers into animal language have presented the results of the studies described below as evidence of linguistic abilities in animals. Many of their conclusions have been disputed.

Famous quotes containing the words sign and/or language:
“Woman—for example, look at her case! She turns tantalizing inviting glances on you. You seize her. No sooner does she feel herself in your grasp than she closes her eyes. It is a sign of her mission, the sign by which she says to man: “Blind yourself, for I am blind.””
—Luigi Pirandello (1867–1936)
“A president, however, must stand somewhat apart, as all great presidents have known instinctively. Then the language which has the power to survive its own utterance is the most likely to move those to whom it is immediately spoken.”
—J.R. Pole (b. 1922)
