Now here's an interesting passage from a report on the "river blindness parasite," but while it's obviously evidence for "evolution," it is not discussed in that framework:
QUOTE: ...Recent reports of patients failing to respond to ivermectin treatment have suggested the emergence of drug-resistant Onchocerca volvulus (the parasite that causes river blindness), and recent studies have associated ivermectin resistance with certain genetic markers, particularly the â-tubulin gene. In Prichard and colleagues' study, genetic changes in â-tubulin were seen in parasites obtained from patients exposed to repeated ivermectin treatment when compared with parasites obtained from the same patients before any exposure to ivermectin... UNQUOTE.
