The speed at which you see changes through evolution depends heavily on the life span of the species in question. (Sorry if this has already been mentioned.)
If an insect dies after a day, natural selection is going to act very quickly. If some bastard creature lives for 200 years, natural selection is going to be far slower. That's why animals with short life spans are generally used when studying evolution "in the lab". Otherwise, you simply won't be able to observe it happening because you yourself will be dead long before there is any noticable change.
It really does make my brain hurt that anyone can think evolution doesn't happen. Random changes around the norm, combined with natural selection, produces a shift in the norm. How hard is that to grasp?
