The black parts on the head that look like a panda’s eyes and nose are just a pattern, and we don’t really know why the pattern is there.”
The hypothesis has been questioned in a recent study by Dr. Eric E.G. Clua and Dr. Carl G. Meyer, published in a Special Issue of the journal Behaviour. They point out that not only is it unsupported by the evidence, but it fails to stand up to close scrutiny.
