In the old days, it was easy. The eagle was a large bird with sharp talons for gripping and a hooked beak for tearing prey; the swallow was a fast-flying bird that left our shores each winter to seek warmer climes. But since Charles Darwin, we can’t say that anymore, because the very language of such descriptions implies purpose – either will (the swallow somehow knowing, planning, its migration) or design.
