Modern biomimesis makes solar cells grow like plants, molecules walk like people, and art run like centipedes. But it's a very old science. Take a look at ancient engineers who made lifelike machines fight, sing, flirt, and yes, poop.
Biomimesis is the science of imitating life. Today, scientists copy the mechanical functions of a body to make robots that can walk, and the functions of a brain to create artificial intelligence. This is one of the forefronts of modern technology, a kind of final frontier.
