The Selk'nam, also known as the Onawo or Ona people, are an indigenous people in the Patagonian region of southern Argentina and Chile, including the Tierra del Fuego islands. They were one of the last native groups in South America to be encountered by migrant Europeans in the late 19th century. In the mid-19th century, there were about 4000 Selk'nam; by 1919 there were 297, and by 1930 just over 100. They are considered extinct as a tribe. The exploration of gold and the introduction of farming in the region of Tierra del Fuego led to genocide of the Selk'nam. Joubert Yantén Gómez, a Chilean mestizo of part Selk'nam ancestry, has taught himself the language and is considered the only speaker; he uses the name Keyuk. While the Selk'nam are closely associated with living in the northeastern area of Tierra del Fuego, they are believed to have originated as a people on the mainland. Thousands of years ago, they migrated by canoe across the Strait of Magellan. Their territory in the early Holocene probably ranged as far as the Cerro Benítez area of the Cerro Toro mountain range in Chile. Lifestyle Traditionally, the Selk'nam were nomadic people who relied on hunting for survival. They dressed sparingly despite the cold climate of Patagonia. They shared Tierra del Fuego with the Haush (or Manek'enk), another nomadic culture who lived in the south-eastern part of the island. Also in the region were the Yámana or Yahgan. Relations with Europeans In Late 1599 a small Dutch fleet led by Olivier van Noort entered the Strait of Magellan and had a hostile encounter with Selk'nam which left about forty Selk'nam dead. It was the bloodiest recorded event in the strait until then. The Selk'nam had little contact with ethnic Europeans until settlers arrived in the late 19th century. These newcomers developed a great part of the land of Tierra del Fuego as large estancias (ranches), depriving the natives of their ancestral hunting areas. Selk'nam, who considered the sheep herds to be game rather than private property (which they did not have as a concept) hunted the sheep. The ranch owners considered this to be poaching, and paid armed groups or militia to hunt down and kill the Selk'nam, in what is now called the Selk'nam Genocide. To receive their bounty, such groups had to bring back the ears of victims. Salesian missionaries worked to protect
