Chimpanzees make tools and use them to acquire foods and for social displays they have sophisticated hunting strategies requiring cooperation, influence and rank; they are status conscious, manipulative and capable of deception; they can learn to use symbols and understand aspects of human language including some relational syntax, concepts of number and numerical sequence; and they are capable of spontaneous planning for a future state or event. Chimps communicate in a manner similar to human nonverbal communication, using visualization, hand gestures, and facial expressions.
Research into the chimpanzee brain has revealed chimp communication activates an area of the chimp brain in the same position as Brooch's area, a language center in the human brain. Studies have found that chimps are capable of learning a limited set of sign language symbols, which they can use to communicate with human trainers. 3. STUDIES OF LANGUAGE Scientists have long been fascinated with the studies of language, believing it to be a unique human cognitive ability. To test this hypothesis, scientists have attempted to teach human language to several species of retreat apes.
One early attempt by Allen and Beatrice Gardner in the sass involved spending 51 months teaching American Sign Language (SSL) to a chimpanzee named Washoe. The Gardeners reported Washoe learned 151 signs, and she had spontaneously taught them to other chimpanzees. Over a longer period of time, Washoe learned over 800 signs. 4. MEMORY A 30-year study at Kyoto University Primate Research Institute has shown chimps are able to learn to recognize the numbers 1 through 9 and their values.
The chimps further show an aptitude for photographic Emory, demonstrated in experiments in which the Jumbled digits are flashed onto a computer screen for less than a quarter of a second, afar which the chimp, Mummy, is able to correctly and quickly point to the positions where they appeared in ascending order. The same experiment was failed by human world memory champion Ben Primmer on most attempts. 5. LAUGHTER Laughter might not be confined or unique to humans. The differences between chimpanzee and human laughter may be the result of adaptations that have evolved to enable human speech.
Self-awareness of one's situation s seen in tomorrow test, or the ability to identify with another's predicament, are prerequisites for laughter, so animals may be laughing in the same way as humans do. 6. OTHER -Adult common chimpanzees, particularly males, can be very aggressive. They are highly territorial and are known to kill other chimps -Chimpanzees also engage in targeted hunting of lower-order primates such as the red colossus and bush babies,and use the meat from these kills as a "social tool" within their community. -In February 2013, a study found chimpanzees solve puzzles for entertainment.
