WebFlight appears to have evolved separately four times in history: in insects, bats, birds and pterosaurs. These four groups of flying animals didn’t evolve from a single, flying ancestor. Instead, they all evolved the ability to fly from separate ancestors that couldn’t fly. This makes flight a case of convergent evolution. The evolution of birds began in the Jurassic Period, with the earliest birds derived from a clade of theropod dinosaurs named Paraves. Birds are categorized as a biological class, Aves. For more than a century, the small theropod dinosaur Archaeopteryx lithographica from the Late Jurassic period was considered to have been the earliest bird.
