Smoking Monkey

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.
Empathy
Recent studies have shown that chimpanzees engage in apparently altruistic behaviour within groups, but are indifferent to the welfare unrelated group members.
