If the environment called for it.
If so, would it survive?
If the adaptation was a result of a change in environment, then the change would be necessary for survival.
I can also point out the exmples of the woodpecker and the Cleaner-Fish and demonstrate that it is an impossibility for these creature to have evolved naturally. Each of these two examples show intellegent design
I don't think they do. Mutualism supports evolution. Please expand.
But can you demonstrate a finch turning into a lizzard, or a dog?
Sure, have you got a couple hundred finches, a lot of land and a few hundred thousand years?
