Where: West Africa
Who: Chimpanzees

Summary:
Have chimpanzees been using hammers for over 4,300 years? In West Africa, a team of researchers discovered hammers and realized that chimpanzees use this tool. The hammers were used to crack nuts and it made the chimps have a behavior affects. They realized that the chimps and other living creatures used this stone hammer in the 1600s. The tool was about the size of a cantaloupe. It would be too big for human hands, but perfect for larger, stronger hands of the chimps. However, there were no humans back then, so the chimpanzees couldn't have got the tool from villagers. Some of the hammers had a little residue on them, which made you think the chimpanzees used it. In conclusion, chimpanzees were a smart animal to be using stone hammers. Also, I feel that the researchers should do more research on chimps because they could find more artifacts and more tools that we may not have discovered yet.
