Sometimes while waiting in the parking lot, I watch the finches peck bug parts out of radiators and tires, or flit away with a stray french fry in their beaks. I think of Charles Darwin and his speciation theory and think that one day, hundreds if not thousands of years from now, a species of finch will become endangered because GM or Ford discontinued radiators in their cars, and their beaks will have become so specialized to that shape that the birds can no longer survive without them to provide tasty bug tussels for sustenance.
