The first Americans were descendants from Australian aborigines, according to evidence in a BBC documentary series called Ancient Voices. Where did they come from? When did they first arrive here? The documentary also answers those questions.
The program shows that the dimensions of prehistoric skulls found in Brazil match those of the aboriginal peoples of Australia and Melanesia. Other evidence suggests that these first Americans were later massacred by invaders from Asia.
Until now, native Americans were believed to have descended from Asian ancestors who arrived over a land bridge between Siberia and Alaska and then migrated across the whole of north and south America. The land bridge was formed 11,000 years ago during the ice age, when sea level dropped.
However, the new evidence shows that these people did not arrive in an empty wilderness. Stone tools and charcoal from the site in Brazil show evidence of human habitation as long ago as 50,000 years. Evidence of fire usage, rock art paintings, and some of the oldest skeletal remains ever found in the America's have established a new timeline for the arrival of modern humans in the America's. Analysis on skulls found show that they are more similar to the bone structure of Africans and Australian Aborigines.
