Is it possible that evolution does work as a mechanical means of God's Plan?

That is not evidence for evolution. If anything, it could be gender, or choice of habitat by the fish. One caught in the shallows and one in deeper water. Scientist are really aggressive when it comes to "clifying" new species. Isn't it still a trout? We seem the same thing in bugs. Those who have more moisture and food seem to develop differently from those who don't. People see what they want to, including scientist.
