You guys still don't get it. The mutation in this case make the plant less effencient. In essence the plants are in a sense devolving as they 'evolve' so as to modify themselves to fit the environments they now live in.

Mutations can be beneficial, neutral or detrimental. It's still possible for a species to survive with a detrimental mutation, but its odds are not as good. A less efficient plant in a more forgiving environment may survive alongside the more efficient ones; it's simply at greater risk of becoming extinct if conditions change.

I think that the poor understanding of evolution among theists is due in large part to how it is presented in many books and television shows, where we are often told (or it is implied) that a creature evolved a feature to better deal with its environment. That's not the case.
