Inelegant, Inefficient, Intelligent?

  If you've ever suspected that the complexity and perfection of the human body are evidence that it must have been deliberately sculpted by an intelligent hand, I'd like to introduce you to the epiglottis. It's a small flap of cartilage in the back of your throat, that hangs out just behind your tongue. When you swallow, it lays down to block off the opening to your larynx, directing food and liquids into your esophagus, and away from the "gas only" zone that is your lungs.

  If something did deliberately design human anatomy, it made the choice to channel all the normal states of matter through a single space, with only a small flap of mucous-covered cartilage to play traffic cop between the lungs and the stomach. It's both needlessly complex and downright dangerous. Building separate, dedicated pathways for breathing and swallowing would have been simpler, and far less prone to catastrophic failure.

  If the human body were intelligently designed, Dr. Heimlich would have died in obscurity.
