Are Birds Dinosaurs? The Evidence Explained

Yes — birds are living dinosaurs. Specifically, they are theropod dinosaurs in the group Maniraptora, closely related to dromaeosaurs like Velociraptor. The evidence is overwhelming: over 100 shared skeletal features, feathered dinosaur fossils, wishbones (furculae) in both groups, hollow bones, brooding behavior, and similar eggshell microstructure.

Archaeopteryx from 150 million years ago shows the transition. Modern birds evolved from a group of small, feathered theropods that survived the asteroid impact 66 million years ago..
