The crab sitting on the horse

The interconnectedness of things is underlined by the living. The spinal chord is but the tail of the shelled crab of the brain which sits atop the great horse of the body. What was once the gill of the floating fish is now the voice-box, pulsing the laryngeal linguistics of gloating expression. It was the trees that taught the brachiating primate the advantages of an opposed thumb. And the elegant earthworm continues to crawl over all the bones of the world.
