It is not only facts, it works so well that farmers,selectioners, biologists, researchers, etc. use it in everyday life. And survival of fittiest makes those bacteria mutations which are less sensitive to drugs to prosper, and makes biosientists try nower and dedlies chemicals, or design new fages using principles of evolution.

So, it is only uneducated and undereducated who now claim that "evolution is wrong". Well, the only advice to ignorant person who claims so is to take a textbooks and catch up with facts in order not to be laught at. Or not to buy any food, as almost all of it is made by selection - main principle of evolution.
