Antimerism

/ænˈtɪmərɪzəm/ noun

Definition

The principle, practice, or theory of antimeres; the state of having bilateral or mirror-image symmetry in biological structures.

Etymology

From antimere + -ism suffix. Used in theoretical biology to describe the concept of symmetrical organization and its implications for evolution and anatomy.

Kelly Says

Antimerism isn't just about symmetry—it's a fundamental principle that allowed complex life to evolve. The moment animals developed bilateral (antimeric) bodies around 600 million years ago, nervous systems and brains became possible, eventually leading to consciousness itself.
