Introduction

Before the 1970s, the Korowai people of
Papua were an uncontacted people. Their population numbers no more than 3,000.

An ethnic group or an ethnicity is a category of people who identify with each other based on similarities such as common ancestry, language, history, society, culture or nation. Ethnicity is usually an inherited status based on the society in which one lives. Membership of an ethnic group tends to be defined by a shared cultural heritage, ancestry, origin myth, history, homeland, language or dialect, symbolic systems such as religion, mythology and ritual, cuisine, dressing style, art or physical appearance.

Ethnic groups, derived from the same historical founder population, often continue to speak related languages and share a similar gene pool. By way of language shift, acculturation, adoption and religious conversion, it is sometimes possible for individuals or groups to leave one ethnic group and become part of another (except for ethnic groups emphasizing homogeneity or racial purity as a key membership criterion).
