And there's a reason why Relativity is still called "The Theory of Relativity" though it's been experimentally proven and has a wide variety of practical uses in science.
The basic problem is the scientific definition of "theory" has little resemblance to the misunderstanding of the definition of "theory" to the scientifically illiterate public.

I couldn't help but notice from the article that "the great philosopher of science Karl Popper suggested that the standard version of evolution even falls short of being a scientific theory, being instead an untestable tautology". Untestable tautology. He also called it a "metaphysical research programme" (Karl Popper, Unended Quest (Glasgow: Fontana, Collins. 1976), p.151).
