Anthropology is the study of humans and human behaviour and societies in the past and present. Social anthropology and cultural anthropology study the norms and values of societies. Linguistic anthropology studies how language affects social life. Biological or physical anthropology studies the biological development of humans.
Ethnology (from the Greek ἔθνος, ethnos meaning "nation") is the branch of anthropology that compares and analyzes the characteristics of different peoples and the relationship between them (cf. cultural, social, or sociocultural anthropology).
The anthropologists got it wrong when they named our species Homo sapiens ('wise man'). In any case it's an arrogant and bigheaded thing to say, wisdom being one of our least evident features. In reality, we are Pan narrans, the storytelling chimpanzee.
