Why an Atheist Thinks the Shroud of Turin is the Real Deal

Bacterial Flagella

Bacterial flagella, it is suggested, are irreducibly complex biological systems. They consist of microscopically small filaments attached to a microscopically small rotary engine, that is part of the bateria. (Yes, that is exactly what it is, a small engine). The engine has a part, a rotor that turns at up to 1000 rpm. The attached filament whips about when the rotor turns and this action propels bacteria through fluids. Altogether, more than forty different protein parts are required to make the flagellum function. Remove any one part and the system will not work. Genetic instructions must exist not only to make each of the parts but also to assemble them correctly in the correct sequence. It is quite an amazing thing. And it is easy to surmise that this is beyond Darwinian evolution.
