Zoology is “the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems.”

Anthropology, which has four fields: (1) sociocultural anthropology; (2) linguistics; (3) archaeology; and (4) physical anthropology. Physical anthropology is sometimes called biological anthropology, as it studies the non-cultural aspects of humans and near-humans (primates).

Anthropology is the study of all aspects of humans. Zoology is the study of animals which also includes humans as animals. So that’s the overlap. That specialty is called Physical Anthropology.

Zoology and biological anthropology  study the same domains, yet they apply different research methods.
