Your kidding right? We just got done talk about the embryo thing. They use to tout that as clear irrefutable proof. The of evidence for evolution may grow (I will not make that broad arrogant assumption that I know the running total on that score) but a great many things once thought to be key evidence have been refuted. That is a fact. Maybe things have replaced them and maybe those will get refuted too. To believe they will not to the point of not questioning is the leave that path of science and dabble in the area of pure faith.
I'm not aware of anything that was key to Darwin's theory or any modern version of the theory that has been refuted. Haeckel's embryo drawings were dry-labbed, but he was basically correct.
What examples do you have of any evidence refuting evolution?
