Using tools to dig for food underground was once thought to be a behavior unique to humans.
Scientists have observed chimpanzees in captivity spontaneously working out how to use tools to dig up buried food, according to research published in the open-access journal PLOS ONE.
"However, the chimpanzees were not habituated to human observers and thus we never saw them excavating," she said."We based our discovery on indirect evidence such as holes, partially bitten USOs, wadges, knuckle prints, etc. Later the same was reported for another site in Senegal, but again the chimpanzees could not be observed, because they were not used to people."
Because researchers could not observe chimps excavating in the wild, Hernandez-Aguilar and her team decided to study a 10-strong chimp colony at the Kristiansand Zoo—located just under 200 miles southeast from the Norwegian capital Oslo—to gain a better understanding of how this behavior developed. The team found that the chimps spontaneously used tools to excavate the buried foods. In the first experiment, nine out of the 10 chimps successfully dug up the buried fruit at least once, with eight choosing to use the prepared tools over their own hands. In the second experiment, the chimps collected their own tools from around their enclosure.
