I've got to ask again since you sidestepped it the first time. Do you not see the oddness in thinking that Mallards and Black ducks are, by your view... evolving and Teal are not? That Mallards and Blacks share a common ancestor and Teal do not.
The fact that one species may evolve more than another within the same family, or in a different way, does not change anything about that family of species because ducks are still ducks.
