Great ape language

Facial expressions can be used to convey a message.

Great ape language research historically involved attempts to teach chimpanzees, bonobos, gorillas and orangutans to communicate using imitative human speech, sign language, physical tokens and computerized lexigrams. These studies were controversial, with debate focused on the definition of language, the welfare of test subjects, and the anthropocentric nature of this line of inquiry.

The consensus among linguists remains that language is unique to humans.[1]

Contemporary research has steered away from attempting to teach apes human language and focuses instead on observing apes' intraspecies communication in zoos and natural habitats. This includes gestures, facial expressions, and vocalizations.[2][3][4][5]
