This reminds me a bit of the some of the problem solving experiments done comparing pet dogs to undomesticated wolves. The experiment wasn't overly complicated, a piece of meat was placed in a locked cage and the animals were given free reign to try their paws at getting to the food. The wolves were persistent, some employed tools like sticks to push the food out, some managed to navigate the clasping mechanism on the cage. The domesticated dogs more often than not quickly gave up and looked to the human present for help.
