 The Bacterial Flagellum |
Certain bacteria use a microscopic whip or flagellum to propel themselves through their liquid environment. This organic engine does not run on the energy kept in a ready state in the ATP molecules inside the cell. Instead, it has its own particular source of energy: The bacterium uses the energy it receives from a flow of acid from the membrane. Some 240 separate proteins make up the bacterial whip. Scientists say that these proteins emit signals to turn the microscopic engine on and off and form joints that permit movement at the atomic level.
This complex structure in the bacterial flagellum alone is sufficient to demolish the theory of evolution. The whip itself has a structure, which can by no means be reduced to a simple form. If only a single molecular piece that constitutes the whip were absent or defective, the flagellum would not function and would therefore be of no use to the bacterium. This yet again clearly reveals the invalidity of the theory of evolution's claim of "gradual development."
