What: "A good example in biology is the bacterial flagellum, the tail on a bacterium that provides propulsion. The flagellum is like an outboard motor. It has parts that resemble a propeller, a motor, a drive shaft, bushings, etc. If any one of the forty parts is missing, the flagellum doesn't work. Therefore, the flagellum could not have evolved piece by piece because if any piece is missing, it doesn't work at all!"
