Monkeys used stone tools 700 years ago
Primate archaeology is a new and unusual-sounding field, but it has revealed ancient evidence of some clever and dextrous monkey culture.
Researchers from Oxford University, working in Brazil, found ancient "nut-cracking tools" - 700-year-old stone hammers that capuchin monkeys used to open cashew nuts.
One of the researchers, Dr Lydia Luncz, explains how the team found evidence of these "Stone Age monkeys".
