I think the worst case of this in science is the way that evolution is described in a way that implies an active process rather than just random mutations which may or may not make organisms more fit for survival.
Yeah, I think that's the most common one. Strongly connected with the idea that evolution is "improvement" or some kind of step along a road to being "better", which I've seen trip up a lot of people who normally don't get confused about this kind of thing.
