Modern developments
The existing nomadic hunters and gatherers are marginal survivors who retain many archaic culture traits and share very few of the more recent inventions. In areas where they have not had contact with European culture or where they have withdrawn into refuge areas, they have maintained much of their original culture. In areas of contact, some have become rudimentary agriculturalists, building permanent houses, making pottery, and weaving. In the late 20th century, the conversion of the nomadic habitat into large-scale agricultural projects seemed to be bringing many of these tribal peoples to the verge of extinction.
