patgundScientists Study Gorilla Who Uses Tools
"An infant gorilla in a Congo sanctuary is smashing palm nuts between two rocks to extract oil, surprising and intriguing scientists who say they have much to learn about what gorillas can do - and about what that says about evolution.
It had been thought that the premeditated use of stones and sticks to accomplish a task like cracking nuts was restricted to humans and the smaller, more agile chimpanzees. Then in late September, keepers at a Dian Fossey Gorilla Fund International sanctuary in this eastern Congo city saw 2 1/2-year-old female gorilla Itebero smashing palm nuts between rocks in the "hammer and anvil" technique, considered among the most complex tool use behaviors."
