Bird skull evolution slowed after the extinction of the dinosaurs

A recent study challenges the notion that birds evolved rapidly following the mass extinction of non-avian dinosaurs. Instead, researchers found that bird skull evolution actually slowed down compared to non-avian dinosaurs. This slower pace of evolution is attributed to adaptations in beak shape and size.
