The Yanomamö are a large population of indigenous Amerindian people in South America. They reside in the Amazon rainforest, among the hills that line the border between Brazil and Venezuela. Due to the remoteness of their residence, they had remained largely uncontacted by the outside world until the beginning of the 20th century. This allowed them to retain several aspects of their culture that factors such as population explosion and growth in material wealth have eradicated from the rest of the world. As a result, the Yanomamö have come to be one of the most widely studied groups by modern science.The Yanomamö live in villages usually consisting of their children and family. Village sizes vary, but usually contain between 50 and 400 people. In this largely communal system, the entire village lives under a common roof called the shabono. Shabonos have a characteristic oval shape, with open grounds in the center measuring an average of 100 yards. The shabono itself constitutes the perimeter of the village, if it has not been fortified with palisade walls.

The Korowai, also called the Kolufo, are a people of southeastern Papua (i.e., the southeastern part of the western part of New Guinea). They number about 3,000. Until 1970, they were unaware of the existence of any people besides themselves.The majority of the Korowai clans live in tree houses on their isolated territory. Since 1980 some have moved into the recently opened villages of Yaniruma at the Becking River banks (Kombai-Korowai area), Mu, and Mbasman (Korowai-Citak area). In 1987, a village was opened in Manggél, in Yafufla (1988), Mabül at the banks of the Eilanden River (1989), and Khaiflambolüp (1998). The village absenteeism rate is still high, because of the relatively long distance between the settlements and the food (sago) resources.
