If one doesn’t recognize evolution, taxonomy classifications seem meaningless.

Nonsense. You can classify organisms just as easily under the assumptions that God created similarities between them.

And Creation theory doesn't reject the idea of change within species in response to environmental pressures, either, so there is no argument there.

Just what discovery wouldn't have been possible while observing biological processes with the mindset of "let's discover how God created this structure or system"?

Acutally, Creationists would have a little problem with ring species, wouldn't they?
