[*Sigh'] Without a theory, all one has is a list of creatures. Nothing more. In that case, how would you select an animal upon which to test a drug for humans? Why not use toads? Their plentiful and cheap. Why do we use monkeys? They're so much more expensive to obtain and house. We use them because they're so closely related to us. We get more useful results that way. See what I mean? Doing medical research absolutely demands that evolution be a part of the background -- even if no one specifically thinks about Mr. Darwin.
I don't think so. Intelligent choices in this field can be made without the Theory of Evolution. Without a creationist viewpoint, too, for that matter.
