There is a difference between evolution and natural selection, natural selection being a blatently NON active process, also given that humans helped in this case even NATURAL selection is a mysnomer. You say plant evolution, I say good farming.
Reality doesn't care how you describe it. ;^)

Well, DUH. Evolution is the end result. Natural selection is the mechanism.

What, are humans supernatural? Did they even use direct genetic modification?
No to both. The humans involved here were simply another facet of their environment. The plants evolved accordingly to best propogate their DNA down the line.
Besides, if humans can select for certain traits, why can't environmental pressures? Is there some sort of magic involved, or did you not actually think through your knee-jerk comment?
