Darwin's Evolutionary Stakes (1999)

An excited announcer calls the next race on the card, the 200-million-year-long Darwin's Evolutionary Endurance Steeplechase. It starts on a hot sticky day at the beginning of the world and ends in the third millennium A.D. Dinosaurs take the early lead, but it comes down to homo sapiens, rats, and cockroaches. A photo finish brings the excitement to a climax.
