The subject matter of anthropology is vast. It includes everything that has to do with human beings, past and present, far and near. Many other sciences and disciplines study one or the other aspect of the most wonderful creature that man is.
While anatomists and physiologists study humans as biological organism and social sciences like economics, sociology, history and other various aspects of human society and culture, anthropologists are interested in all of these things. Thus anthropology may be described as the science of man in totality.
Obviously, it is not possible for a single anthropologist to study and investigate personally everything that has to do with man. That is why anthropology has been divided into various branches and sub fields and individual anthropologists specialize in one or more of these.
