Sociobiologists are scientists who study the biological roots of social behavior in humans and animals. However, there are many other terms used to describe people who research these topics. Ethologists focus on the study of animal behavior, while evolutionary psychologists examine how behaviors develop over time. Behavioral ecologists and behavioral biologists also investigate the relationship between behavior and its evolutionary origins. Some researchers in this field may even be called evolutionary anthropologists, as they explore how humans have evolved socially and culturally. Ultimately, while the term sociobiologist may be the most recognizable, there are many different titles used to describe those who investigate the connections between biology and behavior.
