Ans: Some fossil shreds of evidence prove that modern birds are evolved from Dinosaurs. They belong to the subgroup of theropod dinosaurs. More precisely they belong to the group of Maniraptora. Maniraptora included birds and non-avian dinosaurs of the Jurassic period. Maniraptorans had characteristics that included long arms, three-fingered hands, and semi lunate shaped wrist. Most of the studies belonging to the 21st-century state that the Maniraptorans were more of omnivorous creatures.
