A simplified evolutionary tree showing where bright colors appear on birds and other living species from the study and where these colors may have appeared on their extinct relatives, including dinosaurs; skin (shown in orange), and scales and beak keratin (yellow) could have been brightly pigmented in extinct groups, whereas feathers and claws would probably not have been; areas without bright color are shown in gray.
