Indigenous peoples in Brazil
Indigenous peoples in Brazil or Native Brazilians (Portuguese: Brasileiros nativos) are the peoples whose ancestors lived in Brazil before European contact around 1500 and those pre-Columbian forebears. Indigenous peoples once comprised an estimated 2,000 distinct tribes and nations inhabiting what is now Brazil. The 2010 Brazil census recorded 305 Indigenous ethnic groups.
Historically, many Indigenous peoples of Brazil were semi-nomadic and combined hunting, fishing, and gathering with migratory agriculture. Many tribes were massacred by European settlers, and others assimilated into the growing Brazilian population.
The Indigenous population was decimated by European diseases, declining from a pre-Columbian high of 2 million to 3 million to approximately 300,000 by 1997, distributed among 200 tribes. According to the 2022 IBGE census, 1,694,836 Brazilians classified themselves as Indigenous, divided into 391 ethnic groups and the census recorded 295 Indigenous languages. Almost 77% of Indigenous Brazilians speak Portuguese.
On 18 January 2007, Fundação Nacional do Índio reported 67 remaining uncontacted tribes in Brazil, up from 40 known in 2005. With this increase, Brazil surpassed New Guinea, becoming the country with the largest number of uncontacted peoples in the world.
Questions about the original settlement of the Americas have led to various hypothetical models. The origins of these Indigenous peoples remain a matter of debate among archaeologists.
In Brazil, most Native tribes living in the land by 1500 are thought to be descended from the first wave of Siberian migrants to the Americas, who are believed to have crossed the Bering Land Bridge at the end of the last Ice Age, between 13,000 and 17,000 years ago.
An analysis of Amerindian Y-chromosome DNA reveals specific clustering within much of the South American population. The micro-satellite diversity and distributions of Y-chromosome lineages specific to South America suggest that certain Amerindian populations have been isolated since the initial colonization of the region.
According to a 2012 autosomal DNA genetic study, Indigenous peoples of the Americas descend from at least three main migrant waves from Siberia. Most of their ancestry traces back to a single ancestral population, referred to as the 'First Americans'. However, Inuit-speaking populations from the Arctic inherited nearly half of their ancestry from a second Siberian migrant wave, while Na-dene speakers inherited about one-tenth of their ancestry from a third migrant wave. The initial settlement of the Americas was followed by a rapid expansion southward along the coast, with limited gene flow later, especially in South America. An exception to this is the Chibcha speakers, whose ancestry includes contributions from both North and South America.
