There’s evidence that pre-European Fuegians from Tierra del Fuego, the islands at the remotest southern tip of South America, may be the descendants of mixed Negroid and Mongolian populations.
The Fuegians were pushed to the brink of extinction by European diseases and genocide campaigns, but a number of survivors still show hybrid skull features that could have resulted from procreation between Mongoloid and Negroid people. Their rituals and traditions also bear some resemblance to the ancient rock art of Brazil.
Studies of the ancient DNA samples of Fuegians show they are genetically distinct from other Amerindian groups.
