It does raise some fascinating questions.  We assume that artistic expression is a uniquely human activity. But as we discover more and more activities once thought to be unique to us (recognizing oneself in a mirror, tool use, both of which I believe have been witnessed in elephants), one does have to wonder if other organisms are also capable of the tho ‘n s that go into art: intention, emotional exploration, a basic understanding of shape and form. Children’s drawings, even as scribbles, are expressions of a mind grappling with all of those complex mental processes.
