"The Brontosaurus had a brain no bigger than a crisp. The Dodo had a stammer, and the Mammoth had a lisp. The Auk was just too awkward. Now they're none of them alive; Each one, like Man, had shown himself unfitted to survive. Their story points a moral; now it's we who wear the pants. The extinction of these species holds a lesson for us ants."
