The bacterial flagellum (see basal body of Type III secretory system) and the eyeball (see photo-sensitive cells of just about any invertebrate) have been demonstrated to not be irreducibly complex. Its smaller components can function fine, howbeit different functions.
The proponents of Darwinian evolution just cannot say that the smaller components of the bacterial flagellum and human organs such as the ear and the eye can function fine on their own without providing actual scientific evidence of this.
For instance, in the case of the bacterial flagellum:
Scientists have known about the flagellum for some time. However, its structural details, which have only emerged over the last decade or so, have come as a great surprise to them. It has been discovered that the flagellum moves by means of a very complicated “organic motor,” and not by a simple vibratory mechanism as was earlier believed. This propeller-like engine is constructed on the same mechanical principles as an electric motor. There are two main parts to it: a moving part (the “rotor”) and a stationary one (the “stator”).
The bacterial flagellum is different from all other organic systems that produce mechanical motion. The cell does not utilize available energy stored as ATP molecules. Instead, it has a special energy source: Bacteria use energy from the flow of ions across their outer cell membranes. The inner structure of the motor is extremely complex. Approximately 240 distinct proteins go into constructing the flagellum. Each one of these is carefully positioned. Scientists have determined that these proteins carry the signals to turn the motor on or off, form joints to facilitate movements at the atomic scale, and activate other proteins that connect the flagellum to the cell membrane. The models constructed to summarize the working of the system are enough to depict the complicated nature of the system.

Thanks to this motor, bacteria have been able to move those organs known as “flagella” and thus swim in water.This was discovered in the 1970s, and astounded the world of science, because this “irreducibly complex” organ, made up of some 240 distinct proteins, cannot

The complicated structure of the bacterial flagellum is sufficient all by itself to demolish the theory of evolution, since the flagellum has an irreducibly complex structure. If one single molecule in this fabulously complex structure were to disappear, or become defective, the flagellum would neither work nor be of any use to the bacterium. The flagellum must have been working perfectly from the first moment of its existence. This fact again reveals the nonsense in the theory of evolution’s assertion of “step by step development.” In fact, not one evolutionary biologist has so far succeeded in explaining the origin of the bacterial flagellum although a few tried to do so.
The bacterial flagellum is clear evidence that even in supposedly “primitive” creatures there is an extraordinary design. As humanity learns more about the details, it becomes increasingly obvious that the organisms considered to be the simplest by the scientists of nineteenth century, including Darwin, are in fact just as complex as any others.
The proponents of Darwinian evolution therefore need to refute the
truth of the sound scientific evidence presented above by providing
equally sound scientific evidence of their own that the bacterial flagellum is NOT irreducibly complex.
In the event that they are unable to do this, then they MUST concede that the bacterial flagellum has come into existence by being
created and NOT evolved.
