For first time, monkeys recognize themselves in the mirror, indicating self-awareness

Typically, monkeys don't know what to make of a mirror. They may ignore it or interpret their reflection as another, invading monkey, but they don't recognize the reflection as their own image. Chimpanzees and people pass this "mark" test - they obviously recognize their own reflection and make funny faces, look at a temporary mark that the scientists have placed on their face or wonder how they got so old and grey.
