At the risk of fanning flames in a touchy area of science, I'd have to
agree that minor adaptive changes within a species are indeed
evolution--the only evolution that is proven. Speciation caused by such
changes is merely a theoretical explanation of the diversity which we see
today.
Such resistance development as mites are showing is a crucial part of the
preservation of a species. Unfortunately, we can often aid the development
of resistance through our ignorance, hubris and carelessness, as we
regularly have done through misuse of antibiotics on human and domestic
animal pests.
