Many animals use gestures, grunts, dances, whistles, or even cry to send a message to their other members. Humans have an unbounded discrete combinatorial system. We are able to take many morphemes, combine them together to make other meaningful words. Also, humans have rules and structures which enable us to make sentences. Even with American Sign Language, this language has its own structures and rules. Most animals, such as chickadees, bees’ bats, and other types of birds, are bounded animals. These animals cannot construct new messages. Their way of communication is either through calling or singing. Another example would be the honeybees. Honeybees communicate through dancing. It is evident to show that honeybees do have a discrete combinatorial system. Honeybees are able to put together different dances to convey a message but they are bounded. Animals that have discrete structures are bounded and those that are bounded are discrete.
A study was done on an African Grey parrot named Alex. He was taught many symbols, colors, and numbers. Alex did not have that intelligibility to construct long sentences. Alex had the same intelligence of that of a five year old. His level of intelligibility remained constant. After early attempts to teach chimpanzee’s oral language, many
