Question 6

When he arrived at the Galápagos Islands,Darwin did not observe the amazing tool-using "woodpecker finch" that can modify twigs to pry out grubs.Because there are no true woodpeckers on the Galápagos Islands,this behavior allows this finch to exploit an untapped food source.However,not all members of this species exhibit this behavior,which is probably learned from watching other finches.Therefore,

Accepted Answer

A) young isolated at hatching will not know how to do this. 
B) it is probably not "hardwired" in the brain as a behavior passed on genetically.
