Good points. In fact I *try* to say much the same things in my paper
on classification on my dinosaur Web page.
Would you mind too much if I added some of your comments to my Web page?
> ANCESTRAL SPECIES ARE PARAPHYLETIC
Man, you have ALL of my points!

must be assigned to a genus, then either the genus containing the
ancestral species is paraphyletic or all living things belong to one
The peace of God be with you.
