The theory of evolution may be in big trouble, according to no less an authority than Charles Darwin, its founder.

“If it could be demonstrated,” he once wrote, “that any complex organ existed which could not possibly have been formed by numerous, excessive, slight modifications, my theory would absolutely break down.”

None has been found. In fact there is so much evidence to the contrary, that this point is no longer a consideration. Now the mechanisms are known well enough, that this statement has been relegated to the "proof of a negative" catagory.

1. Darwin did not found the theory of evolution. It was being discussed from before when he was in short trousers, but most people thought it happened because some Intelligence was Designing it to happen.
What Darwin (and wallace, and some Scot forester) did was say it could happen Naturlly, by variation and environmental Selection,

Whereupon everybody struck their forehead with their palm and said "D'oh!"

2. So Darwin proposed a test which would have falsified his Theory, establishing it to be one of Science. Not just a made-up untestable fantasy like ID.
