Humans exhibit bilateral symmetry, which means their body can be divided into two equal halves along a single plane. This type of symmetry is typical of organisms with a defined head, or anterior, and tail, or posterior, enabling streamlined movement. In bilateral symmetry, similar body structures are mirrored on either side of the body, allowing for coordinated movement and complex behaviors. This arrangement aids in sensory perception and navigation, which are crucial for survival and interaction within diverse environments.
