But what about Mammalia? If we exclude them from Reptilia, doesn't that 
render the class paraphyletic, since mammals did evolve from reptilian 
ancestors? I agree that Reptilia is monophyletic, if Mammalia and Aves are 
included (and that's what I should have said in the first place, instead of 
stating that Reptilia, in the older sense of the order, was paraphyletic -- 
which is why I originally qualified "reptiles" with quotation marks).
