Having a head leads naturally to the development of bilateral symmetry. And it also helps you build streamlined fins if you're a fish, aerodynamic wings if you're a bird, or well coordinated legs for running if you're a fox. But, what does this all have to do with evolution? Turns out, biologists can use these various body symmetries

Constantin Brancusi
Romanian Sculptor
When you see a fish you don't think of its scales, do you? You think of its speed, its floating, flashing body seen through the water... If I made fins and eyes and scales, I would arrest its movement, give a pattern or shape of reality. I want just the flash of its spirit.

Edward Albert
American Actor
