Birds Evolved from Maniraptoran Dinosaurs: Study

Researchers from McGill University say that birds have evolved from a group of small, meat-eating theropod dinosaurs called maniraptorans that existed about 150 million years ago.
Many maniraptorans were bird-like as they had small body sizes along with hollow bones, feathers, and high metabolic rates, according to the findings of the researchers.
