Full Answer

In phylogenetics, all animals, including birds, mammals and dinosaurs, that have genetic connections to early reptiles are reptiles. Birds are traced back to the group of feathered dinosaurs that did not die off during the massive dinosaur extinction 65 million years ago. Over time, these dinosaurs evolved into birds. However, in an 18th century classification scheme, the Linnaean system, organisms are grouped together based on common traits. Since reptiles are cold-blooded and have scales, birds do not fall into this category following the Linnaean system.

  • Q:

    What scientific classification are birds?

    A:

    The scientific classification of birds is: Kingdom Animalia, Phylum Chordata, Subphylum Vertebrata, Class Reptilia and Subclass Aves. Many scientists consider Aves to be a subclass of Reptilia, rather than its own class. All birds fall in subclass Aves; after that they are further sub-grouped into different orders, families, genera and species.
