Yeah if you take that taxa should be representative of evolutionary 
history. Which is arguable. If it is based on evolutionary similarity, 
major changes in a single branch make it far more logical to have 
paraphyletic groups. And in a sense, more natural. It just depends on 
how you define natural.
