Anthropology studies the full range of human experience from a variety of perspectives: how human physiology sets the stage for human experience; how language works, and how it is put to work by people; how people lived in the past and how their lives changed; and the ways in which people in different places and in different parts of their societies organize and experience their world today. Anthropologists may study what physiological elements had to be in place for humans to develop complex languages, how environmental changes have been linked to social and cultural change, how women modify their speech in certain situations, or how people think about love and romance in conditions of market liberalization and globalization.
