Quizplus · Accepted Answer

The language experiments with chimpanzees, bonobos, and gorillas indicate that they have some ability to use signs to communicate. While they may not have the same depth or complexity of symbolic communication as humans, they have shown the ability to learn and use sign language or other visual communication systems.
