Has evolutionary science made visible contributions?

I was in a brief discussion with a theist the other day, and while discussing ID Vs. Evolution i noticed nothign has came out of ID that can be used to predict, advance human knowlege, or any real scientific evidence at all..

He asked me, well what has come out of evolutionary science. I replied, "Oh evolutionary biology has allowed us to create thousands of new drugs with the study of evolution"

He replied that evolution was not necessary in the creation of these products, that mere biology would be sufficient for their creation. Though, i am quite ignorant on specific drugs and/or contributions that evolutionary studies have contributed.

Can anybody post discoveries/inventions/or medicines that have been created from an evolutionary standpoint... (link?)
