Yes this is a shameless commercial post for my internet T-shirt shop: Evo-T‘s(hey, I’m poor and domain names and science books don’t pay for themselves).
This one bears a nice quote from the influential philosopher of science Karl Popper (1902-1994) on the tentative nature of scientific conclusions:
The game of science is, in principle, without end. He who decides one day that scientific statements do not call for any further test and that they can be regarded as finally verified, retires from the game. – Popper, Karl (1965) The Logic of Scientific Discovery, Harper Torchbooks, p. 53
This shirt comes in navy blue with yellow print, in sizes for both men and women.
Intelligent design creationism vs. evolutionary theory is no more a controversy than the Earth centered model of the solar system vs. the Sun centered model of the solar system. So if you want to teach the former you might as well teach the latter.
Believe it or don’t, there are still people out there that seriously believe that the Earth is the center of the solar system (if not the universe) and that there is an evil atheist conspiracy to foist “Copernicanism” on the world.
