Animal studies is a recently recognised field in which animals are studied in a variety of cross-disciplinary ways. Scholars who engage in animal studies may be formally trained in a number of diverse fields, including geography, art history, anthropology, biology, film studies, geography, history, psychology, literary studies, museology, philosophy, communication, and sociology. They engage with questions about notions of "animality," "animalization," or "becoming animal," to understand human-made representations of and cultural ideas about "the animal" and what it is to be human by employing various theoretical perspectives. Using these perspectives, those who engage in animal studies seek to understand both human-animal relations now and in the past as defined by our knowledge of them.
