The flagellum motor is composed of a propeller, drive shaft, stator, bushing, u-joint, and is powered by the flow of hydrogen ions.
It can rotate at 6,000 to 17,000 rpm but usually operates at 200 to 1000 rpm.
It can change speeds and reverse direction in a quarter of a turn.
Using this amazing biological motor, the bacteria can propel itself at speeds up to 15 cell lengths per second, which is equivalent to a car traveling 150 miles per hour.
Each shaft rotates a bundle of whiplike flagella that acts as a propeller. Scientists working with ultra-micro devices have learned that the flagella’s whiplike propeller, which at first glance looks awkward and inefficient, is actually perfectly right for propelling a very tiny object through a liquid environment. (See “Making Stuff: Smaller,” NOVA, PBS, 2011.)
“The bacteria can stop, start, and change speed, direction, and even the ‘propeller’s’ shape. They also have intricate sensors, switches, control mechanisms, and a short-term memory” (Brown, In the Beginning, p. 19).
Eight million of the bacterial motors could fit inside the circular cross section of a human hair.
Six thousand years of observation at every level of human existence tells us that even the simplest motor cannot create itself. It is always the product of intelligence, and the more complicated the motor the greater the intelligence necessary to design and build it. The flagellum motor is far more complicated than anything man has built. Common sense unrestrained from naturalistic bias forces the conclusion that this is the product of a very high Intelligence.
Some evolutionists have argued that the flagellum motor could have been “co-opted” from other things. Consider, for example, the following statement:
“The sophisticated components of this flagellum all have precedents elsewhere in nature. In fact, the entire flagellum assembly is extremely similar to an organelle that Yersinia pestis, the bubonic plague bacterium, uses to inject toxins into cells. ... The key is that the flagellum’s component structures ... can serve multiple functions that would have helped favor their evolution” (J. Rennie, “Answers to Creationist Nonsense,” Scientific American, 2002, cited from Jonathan Sarfati, By Design, p. 137).
The simple reply to this is as follows:
(1) To say that the flagellum “could have” been co-opted from parts from other things in nature is a mere “just-so” story with no evidence supporting it. It is an argument built not on scientific fact but on evolutionary assumption and wishful thinking.
(2) Most of the flagellum motor’s components are not found elsewhere in nature and could not therefore have been “co-opted.”
(3) The existence of “parts” found somewhere in nature does not answer the issue of how these were formed in the first place or how they could be combined into a complex working motor. Do dumb bacteria know how to build things? Mutations and natural selection have never been known to create new structures. As Phillip Johnson says:
“... natural selection doesn’t know a thing about bacterial flagella. ... natural selection can only select for preexisting function. ... for co-option to result in a structure like the bacterial flagellum, we are not talking about enhancing the function of an existing structure or reassigning an existing structure to a different function. Rather, we are talking about reassigning multiple structures previously targeted for different functions to a novel structure exhibiting a novel function” (Darwin on Trial, pp. 276, 277).
(4) The incredibly complex instructions for building the flagellum motor are in the bacteria’s DNA. Evolution has never explained scientifically how this information got there.
Dr. Jonathan Sarfati answers this challenge as follows:
“Scientific American’s argument, which comes from Kenneth Miller, and has been parroted by Richard Dawkins, is like claiming that if the components of an electric motor already exist in an electrical shop, they could assemble by themselves into a working motor. However, the right organization is just as important as the right components. Scott Minnich of the University of Idaho, a world expert on the flagellar motor, disagrees with Scientific American and Miller (Minnich points out that Miller, unlike him, has no experience in the area). He says that his belief that this motor has been intelligently designed has given him many research insights. Minnich points out that the very process of assembly in the right sequence requires other regulatory machines. He also points out that only about 10 of the 40 components can possibly be explained by co-option, but the other 30 are brand new” (Sarfati, By Design, pp. 137, 138).
In her zeal to refute the design argument inherent in the complexity of the flagellum motor, one evolutionist has even invoked magic.
“Over at BioLogos, biologist Kathryn Applegate has offered what has to be one of the more creative alternatives to the intelligent design of the bacterial flagellum: Magic. [“Self-Assembly of the Bacterial Flagellum: No Intelligence Required,” The Biologos Forum, Aug. 19, 2010] I'm not kidding. Applegate readily concedes biochemist Michael Behe's point that the flagellum ‘looks and functions just like the outboard motor, a machine designed by intelligent human engineers. So conspicuous is the resemblance that it seems perfectly logical to infer a Designer for the flagellum.’ But, wait, she says: ‘The bacterial flagellum may look like an outboard motor, but there is at least one profound difference: the flagellum assembles spontaneously, without the help of any conscious agent.’ (emphasis added) Acknowledging that ‘the self-assembly of such a complex machine almost defies the imagination,’ Dr. Applegate assures her readers that this is not really a problem because ‘Natural forces work LIKE MAGIC.’ Presto, chango, something appears!” (“Behe Critic on Bacterial Flagellum,” Evolution News & Views, Aug. 25, 2010).
Taken from SEEING THE NON-EXISTENT: EVOLUTION’S MYTHS AND HOAXES. ISBN 1-58318-002-8. This book is designed both as a stand alone title as well as a companion to the apologetics course AN UNSHAKEABLE FAITH. The contents are as follows: Canals on Mars, Charles Darwin and His Granddaddy, Thomas Huxley: Darwin’s Bulldog, Ernst Haeckel: Darwin’s German Apostle, Icons of Evolution, Icons of Creation, The Ape-men, Predictions, Questions for Evolutionists, Darwinian Gods, Darwin’s Social Influence. The ICONS OF EVOLUTION that we refute include mutations, the fossil record, homology, the peppered moth, Darwin’s finches, the fruit fly, vestigial organs, the horse series, the embryo chart, the Miller experiment, Archaeopteryx, bacterial resistance, the big bang, and billions of years. The ICONS OF CREATION that we examine include the monarch butterfly, the trilobite, the living cell, the human eye, the human brain, the human hand, blood clotting, the bird’s flight feather, bird migration, bird song, harmony and symbiosis, sexual reproduction, living technology, the dragonfly, the bee, and the bat. The section on APE-MEN deals with Cro-Magnon, Neanderthal, Java Man, Piltdown Man, Nebraska Man, Peking Man, Lucy, Ardi, Ida, among others. The section on PREDICTIONS considers 29 predictions made by Biblical creationism, such as the universe will behave according to established laws, the universe will be logical, and there will be a vast unbridgeable gulf between man and the animal kingdom. DARWINIAN GODS takes a look at inventions that evolutionists have devised to avoid divine Creation, such as panspermia and aliens, self-organization, and the multiverse. 608 pages.
