Darwin was ahead of his time! Its hard to find another theory that has changed less than Darwin's has.

How much has Newtonian mechanics changed?

Superceded, yes, but changed? ;-)

Cheers!

Not much of Darwin's thinking has been superceded. It's true he didn't know about genetics or DNA, but he wrote extensively about the properties that the inheritable material had to have.
