Self-Taught Elephant Masters Banana Peeling
Pang Pha, an Asian elephant at the Berlin Zoo, has taught herself to peel bananas using her trunk, a behavior that she only engages in when the fruit is at the right level of ripeness. Scientists suspect that she learned the habit from observing her caretakers peel bananas for her. While some experts are not convinced that this is a case of observational learning, the behavior highlights the dexterity of elephants' trunks and their ability to manipulate objects.
