This program analyzes how flight evolved not once but four times, in very different ways. Presenting a number of theories, the program examines how insects, pterosaurs, birds, and bats each took to the sky. Bug wings that may have evolved from larval gills into pond-crossing sails; flight feathers that could have begun as soft down on small dinosaurs; and bat wings that probably developed from the webbed paws of gliding rodents are considered. Convergent evolution and echolocation are also discussed.
