Description: When you hear the word symmetry, you might think generally of triangles, butterflies, or even ballerinas. But defined scientifically, symmetry is "a transformation that leaves an object unchanged." Huh? Colm Kelleher unpacks this abstract term and explains how animals' distinct symmetries can tell us more about them -- and ourselves.

The science of symmetry

Symmetry in biology, from human bilateral to starfish radial, reveals nature's penchant for order and hints at evolutionary paths.

Bilateral symmetry, linking animals from foxes to humans, underpins movement, sensory organ placement, and evolutionary connections.

Exploring the symmetry in organisms offers insights into evolutionary relationships, tracing back to shared ancient ancestors.
