Well, yes, they usually admit to small scale evolution, which they call "micro evolution." But they deny that it has any creative power. They see it, and mutation, as processes of natural deterioration (something akin to rusting).
I guess if you have that point of view, and if you view the mythical Garden of Eden as an ideal, then whenever you see weeds taking over your own garden you see this natural deterioration in effect. It's an example of how one's prior attitudes and beliefs can distort one's observations.
