The study of human cultures is called anthropology. This course, to some extent, is an anthropology course. Unlike historians or geographers or economists or arts historians who focus on just one aspect of a group of people, anthropologists are interested in everything about a people. Anthropologists are sometimes assisted by archaeologists, who study human artifacts, that is, remains of physical objects, such as pottery or tools, in an attempt to reconstruct the physical culture. Everyone human being has a culture, but no one is born with one.
Culture is learned behavior, and enculturation is the learning of a culture.
Culture is not related to one's language or religion or race or ethnic group. Many religions, such as Christianity, Islam and Buddhism, cross cultures. The American culture includes people from dozens of racial and ethnic groups. Every culture has its rules and regulations for ordering the lives of its people. Folkways are rules of ordinary daily behavior, such as etiquette, how we address people, what we use to eat our meals.
