Many researchers discover that chimps can learn a lot of thing that others can’t. Using symbols and teaching them to other chimps is only one of them.  They also understand aspects of human language, including concepts of number and numerical sequence as well as some relational syntax. Chimpanzees make tools and use them to acquire foods, for social displays.  Above all, chimpanzees have a better memory than any other creature, including humans.  They are analytical and good in solving problem, clearly capable of insight and complex “cognitive performance” in both the captivity and in wild, and particularly adept at analyzing relative relationships. After all these traits, sharing 96% of their DNA with ours, chimpanzees deserve to top our list as the smartest animal in the world.
