"That is just rhetoric without at least one to back up your claim."
Then allow me to give Pim a hand:
Finch beaks
Drosophila adaptation experiments (not the ones where they zap them with
x-rays to see what kinds of mutants arise)
Bacterial antibiotic resistence (with the added twist that they do not
revert to a non-resistent state when antibiotics are removed)
Plant heavy metal tolerance
Bacterial adaptation of using toxic waste as food
Anybody have any more examples?
