The origin of the Mapuche has been a matter of research for over a century. The genetics of the Mapuche do not show overly clear affinities with any other known indigenous group in the Americas, and the same goes for linguistics, where the Mapuche language is considered a language isolate. Archaeological evidence shows Mapuche culture has existed in Chile at least since 600 to 500 BC.[1] Mapuches are late arrivals in their southernmost (Chiloé Archipelago) and easternmost (Pampas) areas of settlement, yet Mapuche history in the north towards Atacama Desert may be older than historic settlement suggest. The Mapuche has received significant influence from Pre-Incan (Tiwanaku?), Incan and Spanish peoples, but deep origins of the Mapuche predates these contacts. Contact and conflict with the Spanish Empire are thought by scholars such as Tom Dillehay and José Bengoa to have had a profound impact on the shaping of the Mapuche ethnicity.
Thus the Mapuches are considered of autochthonous origin, with some genetic studies and archaeological and linguistic hypothesis hinting an origin or influence from the Amazon in the distant past.
