Irreducible complexity - Bacterial Flagellum
This video and article, make reference to the work of Prof. Michael Behe, who back in the 1990s, introduced the concept of "irreducible complexity" in biological systems. This concept relates to the idea that working systems are so complex, that they have to be fully in place in order for any part of them to be of any use. One of the key examples used is that of the bacerial flagellum, which is the device used to propel and provide mobility to a bacterial cell. Given that many biological systems are irreducibly complex, the only reasonable conclusion is that they must be the work of an intelligent designer rather than via a process of evolution and random mutations.
