Sophie and the Orangutan...
"Except for humans, orangutans have the longest childhood of any animal in the world. This is partly because they have to learn so much just to survive, just as juveniles in other ape species must do. But whereas babies of more social ape species can learn from multiple adults, orangutan babies depend on just one adult -- their mother. So an extra-long childhood allows time for the mother to teach her offspring everything it needs to know."
