More Facts about Chimps
Chimpanzees in laboratory have demonstrated their ability to find their way
out of the most tortuous maze. They can press buttons, manipulate levers,
avoid shocks, etc. If food is placed out of reach, they can prepare a ladder
of boxes to reach it. In his natural habitat the chimpanzee is something of
itinerant. He goes his nomadic ways through the jungle, living on fruit, 
insects, and vegetables. With the aid of his long, powerful hands he can 
swing rapidly from tree to tree and cover considerable grounds in his 
peregrinations. Chimps are loyal to their conjugal relationships, taking 
only one mate at a time. That may be another barometer of the animal's
superior intelligence.


to wink at--There was a plethora of evidence to show that the border guards
would wink at illegal shipments if they were paid in advance.
