Anthropology is from the Greek anthropos (human) + logia (study). It is the science that studies human variation from its beginnings millions of years ago to the present day. To an anthropologist, diversity itself – seen in body shapes and sizes, blood types, different kinds of languages, customs, clothing, religion and ideas about the world – provides a frame of reference for understanding any single aspect of life.
Archaeologists study the things humans created, used, and left behind to understand ancient societies and how they lived.
Biological anthropologists study our species and its close relatives, tracing their biological origins, development and genetic diversity to understand human evolutionary history.
Cultural anthropologists seek to describe how societies and their institutions are constituted to explain differences among them.
