Body symmetry refers to the balanced and proportional arrangement of body parts on either side of a central axis. In humans, this typically means that the left and right sides of the body are mirror images of each other. Symmetry is often associated with physical attractiveness and can influence perceptions of health and fitness. In nature, many organisms exhibit body symmetry, which can be classified as bilateral, radial, or asymmetrical. For example, butterflies and humans display bilateral symmetry, while starfish exhibit radial symmetry. Symmetry plays a crucial role in various fields, including biology, art, and design.
