The Americas (S01E05)

Dr. Alice Roberts investigates how Stone Age individuals migrated to North and South America. She uncovers evidence of a prehistoric corridor that might have existed through the Canadian ice sheet, facilitating their passage. However, intriguing archaeological discoveries in southern Chile propose an alternative entry method. Additionally, an ancient human skull found in Brazil raises the possibility of an Australasian origin for the first Americans. This leads to the question: was it feasible for them to journey from Australia across the Pacific Ocean?
