Well, I would disagree with the contributions of Darwinian evolution to clinical pathology because of its theory on \"vestigial organs\".
For example, the appendix has long been considered by Darwinian evolutionists as a classical example of a \"vestigial organ\", having no function at all, and a \"waste product\", a \"side effect\" of Darwinian evolution. Because of that idea, years went by before anyone got interested in studying the appendix again. Today, the appendix has been found to have a role in protecting the human body from disease. Here we see an example of how Darwinian evolution, instead of driving medical science forward, in effect held it back.
There are still many cases where Darwinian evolution blocked the advance of science like the tonsils and junk DNA.
