Sociology and Anthropology:Anthropologist Kroeber pointed out that the two sciences Sociology and Anthropology - are twin sisters. Really, the relation between Sociology and Anthropology is widely recognised today. The relations between Sociology and Anthropology are closer than those between Anthropology and Political Science.Like Sociology, Anthropology is a general science. The word 'Anthropology' is derived from two Greek words 'Anthropos' meaning 'Man' and 'logos' meaning 'study'. Thus, the etymological meaning of Anthropology is the study of man. It is defined by Kroeber as the science of man and his works and behaviour.On the other hand, Sociology is derived from the Latin word 'Societus' meaning 'society' and Greek word 'logus' meaning 'study or science'. Thus, the etymological meaning of Sociology is the science of society. In other words, Sociology is the study of man's behaviour in group.
