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 deception; they can learn to use symbols and understand aspects human language including some relational syntax, concepts number and numerical sequence; and they are capable spontaneous planning for a future state or event.
One the most significant discoveries was in October 1960 when Jane Goodall observed the use tools among chimpanzees. Recent research indicates that chimpanzee stone tool use dates to at least 4,300 years ago. Chimpanzee tool usage includes digging into termite mounds with a large stick tool, and then using a small stick that has been altered to "fish" the termites out. A recent study revealed the use such advanced tools as spears, with which Common Chimpanzees in Senegal sharpen with their teeth and use to spear Senegal Bushbabies out small holes in trees. Before the discovery tool use in chimps, it was believed that humans were the only species to make and use tools, but several other tool-using species are now known.
