A groundbreaking study has identified common feather characteristics among flying birds, revealing that all possess 9 to 11 primary feathers, a trait that provides insights into the evolution of flight from dinosaur ancestors. By combining analysis of museum specimens and fossil data, researchers suggest that flight evolved only once among dinosaurs, highlighting the significance of feathers and flight in the evolutionary success of these species.
