We've haven't been arguing about the phylogenetic relationships of
dinosaurs and birds. We've been tallking about whether birds derived
enough in regard to physiology, metabolism, and lifestyle to warrent being
called something different. When you get right down to it, its a totally
subjective argument and theres probably not much more we can do with it.
