Quizplus · Accepted Answer

Chimpanzees have a physical limitation that makes it difficult for them to produce the same range of sounds as humans due to differences in the vocal tract, including the larynx. Additionally, they naturally use gestures to communicate, making sign language a more accessible and natural form of communication for them. Sign language's structured grammar also makes it a suitable medium for studying linguistic capabilities.
