Answer:
N the modern classification system birds are in a separate group from reptiles, but fossil evidence shows they have the same ancestry.
Explanation:
It is true that birds and reptiles are classified in different groups, since they present different anatomical, structural and biological differences, however these animals have several similarities, since they probably descend from the same ancestor.
It is well accepted in the scientific community that birds emerged from groups of dinosaurs, that is, that birds and reptiles were formed by the same ancestor. For many scholars, for reptiles to become a valid group, birds should be part of that group, but it was decided that mantles would be better in different groups.
