Insightful Problem Solving in an Asian Elephant. Kandula, an 8-year old Asian elephant at the Smithsonian's National Zoo, demonstrates insightful problem solving by positioning a tractor tire under a treat that is too high for him to reach. By standing on the tire he can reach the food. From the scientific paper "Insightful Problem Thinking in an Asian Elephant," published Aug. 18, 2011 in the journal PLoS ONE.
