Facial symmetry is very interesting to me. Why did we need symmetry? Why isn’t the human nose on the left and the mouth on the right? Almost all animals and even plants have elements of symmetry. Trees trunks are symmetrical, leaves are symmetrical, and almost all creatures’ faces are symmetrical, from leopards and lions to ants and spiders. Symmetry often resembles and symbolizes balance – scales are balanced when they are symmetrical, for example. Symmetry is everywhere around us, and it only takes the smallest of efforts to notice it.
