Chimps Raised In Captivity Spontaneously Learn How To Use Tools
14 May 2019, 11:41 pm EDT By Diane Samson Tech Times
Chimpanzees in captivity can learn how to use tools on their own to dig for food, a trait initially thought to be unique to humans.
A team of researchers from the University of Oslo has observed 10 chimpanzees at an island enclosure in the Kristiansand Zoo in Norway. Of the 10 chimpanzees, eight were born in captivity. None of the chimpanzees that were chosen to participate in the experiment have previously exhibited excavation behaviors.

Chimpanzees Use Tools To Dig Food
During the experiment, the researchers dug five holes on the ground and placed fruits in them. They initially left the holes open to let the chimpanzees know that there are food in them. They later on covered each hole.
The researchers also initially provided ready-made tree stick and bark tools for the chimpanzees to use. However, in a second experiment, tools were not provided.
