The Unit of Zoology and Biological Anthropology focuses its teaching and research on animal biology from an evolutionary and ecological perspective. These two areas of knowledge, Zoology and Biological Anthropology, were separated into two different departments until they joined in 1985.

The area of ​​Biological Anthropology studies the origin and evolution of the human species and the distribution of the biological variability of their populations. Its objective is to know the mechanisms that generate this variability and how they relate to health, growth, aging, demography and genetics through biosocial interactions.

The area of ​​Zoology is divided into three functional units: Arthropods, Cords and Invertebrates. It focuses its activity on the study of the biology of these groups of organisms: their origin, evolution, distribution, ecology and behavior, both from the point of view of basic and applied research.
