Elephant paintings: amazing display of intelligence

I am taking a trip through Southeast Asia and currently am in northern Thailand where several of us visited an Elephant park.  Part of the elephant show involved five elephants who were stood behind paint easels and for 15 minutes each painted as their handlers handed them bushes. The results were amazing and moved me to wonder once again what precisely separates humans from other beings, in this case highly intelligent mammals. Following the conclusion of this remarkable show I took photos of each elephant's work.  Had I not been there to see this and take photos I am not sure I would have believed this possible.
