Humans’ amazing ability to recognize faces has one limitation; we cannot recognize upside-down faces. Studies have shown that while we can recognize inverted objects, we can’t tell “which of two inverted faces is the original when one has been slightly altered.” Dubbed the Thatcher Illusion, it is a result of our brain evolving a specialized facial recognition area separate from the area used for all other objects. The reason why is very simple; faces are always upright. There’s no need to take up space in the brain with in order to recognize upside-down faces when we almost never see them. We know that we share this evolutional quirk with other primates and even some non-primates like sheep.
