I was watching a program on the origins of life. There was a talk about intelligent design being the cause of life rather than the evolution model.
The proponents of intelligent design cited as an example the flagellum. This is a long thread like structure on certain bacteria that is used for movement.
The flagellum is a miniature motor, it is quite clear from the images that was shown. Their argument was that this was the most simplest form of cell machinery. It is not possible for this structure to evolve. Evolution means smaller changes happening over a course of time that produce a larger entity. If this explanation is applied to the flagellum, then the flagellum would not exist as the flagellum requires all the parts to be present simultaneously for it to exhibit a particular behaviour namely transportation.
Once again scientists differ.
