Bilaterality
Bilaterality refers to a fundamental organizational principle in biology characterized by symmetry around a central plane, dividing an organism into two mirror-image halves. This bilateral symmetry is a common evolutionary trait observed in many animal and some plant species, facilitating coordinated movement, sensory processing, and streamlined body plans.
Organisms exhibiting bilaterality typically have a distinct left and right side, an anterior (front), posterior (back),
The emergence of bilaterality is believed to be an ancient evolutionary development, providing advantages in mobility
In contrast to radial symmetry, where body parts radiate from a central point (common in echinoderms and
Overall, bilaterality is a key feature influencing the morphology, behavior, and ecological interactions of many multicellular
