Who were the first Americans? Where did they come from? When did they first arrive here? This BBC documentary answers those questions. Scientist were stunned to find evidence of civilization in Brazil dating to around 50,000 years ago. 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.
