So take a look at this photo, and you will immediately notice a face. Now the brain has a tendency to do this; it puts a recognizable image onto a featureless pattern, and this phenomenon is called Pareidolia. Pareidolia is when the brain superimposes a known image on another object that is presented to it, and the most familiar thing that the brain imposes is faces. I think it is an evolutionary trait because you want to remember a face as threatening or non-threatening like that. On the internet, you will see many of these instances where people have said, "Oh look! Face of Jesus on a piece of toast!" Things like that. It is pretty interesting what the brain does.
