Explain the importance of the Kanzi experiment in the context of research on primate communication.

Communication with Primate
Early experiments to teach primates to communicate with their voices failed because of the differences in their vocal organs, not their intellectual. Dramatic progress was observed when researchers began to communicate by using American Sign Language. Some chimpanzees were able to learn several hundred signs that they put together to express a number of relations similar to the initial language acquisition of children. In addition, success was achieved by using plastic symbols on a magnetic board, each of which represented a word. For example, a small blue triangle represent an apple. chimpanzees were able to respond correctly to basic sequences and even to form some higher lever concept by using the representative system.
