Intelligent design theory is an argument used by some people to challenge the teaching of evolution in public schools. One of the supporters of this idea claims that certain biological structures, such as the bacterial flagellum, require so many complex parts working together in perfect synchronization that it is not possible that they could have evolved from simpler structures. This argument states that a simpler structure could not perform the same function, which is evidence of "irreducible complexity." This is cited as evidence for an intelligent designer. Do you consider this theory scientific? Why or why not? Would you support the inclusion of this theory in the science classroom? If so, would you also support contrasting this theory to the theory of evolution?
