It is very common for us to see faces in inanimate objects. Faces are such common things in our experience that people can see faces in all sorts of objects. The ability of our brains to recognize non-faces as faces may be a result of our neural architecture, but scientists believe that this may also be a survival strategy. They think that facial recognition, whether inherited or a learned behaviour, may be a critical reason for our evolutionary success story.
