Some fields focus on particular animal groups, such as ichthyology (the study of fishes), ornithology (the study of birds), and entomology (the study of insects). Others examine certain aspects of how animals are structured, how they function, or how they are related to one another. These fields include genetics, anatomy, ecology, behavior, and many others. Evolutionary biology focuses on the determination of animal origins and relationships and thus encompasses all of the fields of zoology. The study of birds including living and fossil forms.
