The top box contains observations Darwin either explained or employed in his explanations. Nothing in this box can ever be valid scientific evidence for his explanation.

The second box contains evidence Darwin did not have available. The things in this box may be evaluated as potential evidence in favor of his explanations.

The third box contains special cases.

I can't claim to have thought of everything, but this is what we have so far. I think almost anyone can readily see how to formulate circular arguments in favor of Darwin's theory of evolution, and I hope people will understand how to spot such arguments when they are encountered.

We have also gained a little experience here, and seen how rigourous some would have us be when subjecting Darwin's theory to scientific scrutiny. It is hoped that not all proponents would react in this fashion.

"We find that such evidence demonstrates that the ID argument is dependent upon setting a scientifically unreasonable burden of proof for the theory of evolution." - Judge Jones Kitzmiller case

"To Compel A Man To Furnish Funds For The Propagation Of Ideas He Disbelieves And Abhors Is Sinful And Tyrannical." - Thomas Jefferson

"And can the liberties of a nation be thought secure when we have removed their only firm basis, a conviction in the minds of the people that these liberties are the gift of God? That they are not to be violated but with his wrath?" - Thomas Jefferson
