TED-ED: The science of symmetry - Colm Kelleher

The video explores the concept of symmetry, starting with its general perception in everyday life and its specific definition in math and science. It explains symmetry as a transformation that leaves an object unchanged, using examples like equilateral triangles. The video then delves into biological symmetry, discussing bilateral and radial symmetries in various organisms and their evolutionary significance. It highlights how symmetry can indicate evolutionary relationships, such as the connection between humans and starfish. Overall, the video emphasizes the importance of symmetry in understanding both mathematical concepts and biological evolution.
