Chimpanzees Outsmart* Humans, Sabotage Traps*

Throughout Africa, people lay traps to catch chimpanzees and other animals for food.
But chimpanzees in the rainforests of the Republic of Guinea, in western Africa have learned how to recognize* the traps and deactivate them.
“They seemed to know which parts of the snares* are dangerous and which are not,” said primatologist Gaku Ohashi.
The chimpanzees used more than one method, but always avoided* touching the dangerous part of the trap, the wire loop.*  “We were surprised when we found this behavior,*” Ohashi said.  “This is the first report of chimpanzees breaking snares without injury.*
There are two important things that scientists have learned from this.  The first is about the way that chimpanzees learn.  “The observations* indicate* that chimpanzees can learn some behavior without trial* and error,”
Ohashi said.  That is because an error
while handling the traps would probably be fatal.  So, they can learn through analysis, which requires more intelligence and imagination.
The second thing is that they are capable of teaching each other and passing down* their knowledge to their children.
Scientists watched as, in one case, an older chimp dismantled* a trap while a younger one watched and then examined the destroyed trap.
