Anthropology(人类学) is the study of how people live. It includes their family life, religion, art, laws and language. The term "anthropology" comes from two Greek words: "anthropos" means "human being" and "logy" means "the science of". Anthropology can be divided into two areas. These two main divisions are cultural anthropology and physical anthropology. Culture includes many things, such as art, religion, laws, and even furniture and movies. Anthropologists define human progress in three main steps. Step one begins with the first human being and continues until the last of the people who hunted animals just to survive. Step two includes people who grew food. In this step, there was progress in invention and religion. Step three deals with the first civilizations, such as those in Egypt and parts of Asia. Anthropologists always seek new information about people.
