Question: The Ona people populated what continent?

full_context: Document 1: Persecution of Degar Peoples in Vietnam: The native inhabitants of the Central Highlands are the Degar (Montagnard) peoples. The Vietnamese conquered the Central Highlands during their "march to the south" (Nam tiến). Ethnic Vietnamese (Kinh) people now outnumber the indigenous Degars after state sponsored colonization directed by both the government of South Vietnam and the current Communist government of unified Vietnam. The Montagnards have engaged in conflicts with the Vietnamese, from the anti-Communist South Vietnamese government, the Viet Cong, to the Communist government of unified Vietnam.
Document 2: Selk'nam people: 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 ethnic Europeans or Westerners in the late 19th century. With the discovery of gold and expansion of sheep farming, the Argentine and Chilean governments began efforts to explore, colonize and commit genocide against the indigenous peoples of Tierra del Fuego (the "land of fire", named by early European explorers observing smoke from Selk'nam fires) into their cultures.
Document 3: Tierra del fuego (film): Tierra del fuego is a 2000 Chilean drama film directed by Miguel Littín. Based on a short story of the same name by Francisco Coloane, it is about the conquest of Tierra del Fuego by Julius Popper. It was screened in the Un Certain Regard section at the 2000 Cannes Film Festival.
Document 4: Helmet massacre: The Helmet massacre (Portuguese: "massacre do Capacete" ] ) of the Tikuna people took place in March 1988, in the municipality of Benjamin Constant, in the Alto Solimões region, in a remote area in the state of Amazonas. Funai, the National Foundation for the Indians, had begun to demarcate the Tikuna land, giving rise to reactions from local squatters. The indigenous people were gathered in an assembly and were unarmed when they were attacked. During the massacre four people died, nineteen were wounded, and ten disappeared in the Solimões river. It was initially treated as homicide. Since 1994 it has been treated by the Brazilian courts as a genocide. Thirteen men were convicted of genocide in 2001. In November 2004 at the appeal before Brazil's federal court, Castelo Branco, the man initially found guilty of hiring men to carry out the genocide was acquitted, and the other men had their initial sentences of 15–25 years reduced to 12 years.
Document 5: Patagonia Rebelde: Patagonia Rebelde (or Patagonia Trágica) ("Rebel Patagonia" or "Tragic Patagonia" in English) was the name given to the violent suppression of a rural worker's strike in the Argentine province of Santa Cruz in Patagonia between 1920 and 1922. The uprising was put down by colonel Héctor Benigno Varela's 10th Cavalry Regiment of the Argentine Army under the orders of President Hipólito Yrigoyen. Approximately 1,500 rural workers were shot and killed by the Argentine Army in the course of the operations, many of them executed by firing squads after surrendering. Most of the executed were Spanish and Chilean workers who had sought refuge in Argentina's Patagonia after their strike in the city of Puerto Natales in southern Chile on 27 July 1920 was crushed by the Chilean authorities, at the cost of four carabineers killed. At least two Argentine soldiers (corporal Domingo Montenegro and private Fernando Pablo Fischer), three local policemen (sergeant Tomás Rosa and constables Ernesto Bozán and Juan Campos) and a number of ranch owners and their relatives also died during the strife.
Document 6: Chonan languages: The Chonan languages were spoken in Tierra del Fuego and Patagonia. Two Chon languages are well attested: Selk'nam, spoken by the people of the same name who occupied territory in the northeast of Tierra del Fuego; and Tehuelche spoken by the people of the same name who occupied territory north of Tierra del Fuego. The name 'Chon', or "Tshon", is a blend of 'Tehuelche' and 'Ona'.
Document 7: Patagonia: Patagonia (] ) is a sparsely populated region located at the southern end of South America, shared by Argentina and Chile. The region comprises the southern section of the Andes mountains as well as the deserts, pampas and grasslands east of this southern portion of the Andes. Patagonia has two coasts: western facing the Pacific Ocean and eastern facing the Atlantic Ocean.
Document 8: Selk'nam genocide: The Selk'nam genocide was the genocide of the Selk'nam people, who were one of three indigenous tribes populating the Tierra del Fuego in South America, from the second half of the 19th to the early 20th century. Spanning a period of between ten and fifteen years the Selk'nam, which had an estimated population of some three thousand, saw their numbers reduced to 500.
Document 9: Genocide of indigenous peoples in Brazil: The process that has been described as the genocide of indigenous peoples in Brazil began with the Portuguese colonization of the Americas, when Pedro Álvares Cabral made landfall in what is now the country of Brazil in 1500. This started the process that led to the depopulation of the indigenous peoples in Brazil, because of disease and violent treatment by European settlers, and their gradual replacement with colonists from Europe and Africa. This process has been described as a genocide, and continues into the modern era with the ongoing destruction of indigenous peoples of the Amazonian region.
Document 10: Indigenous peoples in Argentina: Argentina has 35 indigenous groups or Argentine Amerindians or Native Argentines, according to the Complementary Survey of the Indigenous Peoples of 2004, in the first attempt by the government in more than 100 years to recognize and classify the population according to ethnicity. In the survey, based on self-identification or self-ascription, around 600,000 Argentines declared to be Amerindian or first-generation descendants of Amerindians, that is, 1.49% of the population. The most populous of these were the Aonikenk, Kolla, Qom, Wichí, Diaguita, Mocoví, Huarpe peoples, Mapuche and Guarani In the 2010 census , 955,032 Argentines declared to be Amerindian or first-generation descendants of Amerindians, that is, 2.38% of the population. Many Argentines also claim at least one indigenous ancestor: in a recent genetic study conducted by the University of Buenos Aires, more than 56% of the 320 Argentines sampled were shown to have at least one indigenous ancestor in one parental lineage and about 11% had indigenous ancestors in both parental lineages.
Document 11: List of genocides by death toll: This list of genocides by death toll includes death toll estimates of all deaths that are either directly or indirectly caused by genocide. It does not include non-genocidal mass killing such as the Thirty Years War (7 & 1/2 million deaths), Japanese War Crimes (3 to 14 million deaths), the Atrocities in the Congo Free State (3 to 13 million deaths), the 1965–1966 Indonesian Politicide (1/2 to 3 million deaths) or the Great Leap Forward (15 to 55 million deaths).<br>
Document 12: Patagonian Welsh: Patagonian Welsh (Welsh: "Cymraeg y Wladfa") is the name given to the Welsh language as spoken in Y Wladfa, the Welsh settlement in Patagonia, Argentina, specifically in the province of Chubut. There is no evidence to suggest there are still any first language speakers remaining. Claims about the number of native speakers refer to second language speakers or language learners.
Document 13: Terra Indigena Uru-Eu-Uaw-Uaw: Terra Indigena Uru-Eu-Uaw-Uaw is an indigenous territory located in central Rondônia, Brazil. It has a contacted Indian population of around 168 people belonging to Amondaua, Uru Pa In, Juma, and Jupaú tribes (as of 2002). There remains an unknown number of uncontacted Indians who belongs to 4 to 6 different tribes like Jururei, Yvyraparaquara, Uru Pa In (uncontacted bands) and Parakua. The uncontacted population was estimated at somewhere between 1,000 and 1,200 in 1986, but it has declined very steeply in the recent decades. It is one of the most unsafe indigenous territories in Brazil and is regularly invaded by loggers and ranchers. The Jururei tribe was subjected to mass killings in 2003 and 2005. Most of the Jupaú are now Christian, while the other tribes are entirely animist.
Document 14: Nicoleño: The Nicoleño were a Uto-Aztecan Native American tribe who lived on San Nicolas Island, California. Its population was "left devastated by a massacre in 1814 by sea otter hunters". Its last surviving member was given the name Juana Maria, who was born before 1811 and died in 1853.
Document 15: Population of Native California: Estimates of the Population of Native Californians prior to and after European contact have varied substantially. Pre-contact estimates range from 133,000 to 705,000 with some recent scholars concluding that these estimates are low. Following the arrival of Europeans in California, disease and primarily the late 19th century California Genocide reduced the population to as low as 25,000. During and after the California Gold Rush, it is estimated that miners and others killed about 4,500 Indigenous people of California between 1849 and 1870. As of 2005, California is the state with the largest self-identified Native American population according to the U.S. Census at 696,600.
