According to Heyerdahl's theories, ancient peoples may have come to North America from which continent?

Thor Heyerdahl is best known for his theories regarding ancient migration patterns, particularly his view that the Polynesians could have originally come from South America across the Pacific Ocean, rather than from Asia as was commonly believed. However, regarding the specific question about ancient peoples potentially coming to North America, Heyerdahl proposed the idea that some migrations could have originated from Africa. This was based on his larger theories surrounding ancient sea travel and the capability of early peoples to navigate vast oceans.

Heyerdahl's work emphasized the possibility that ancient civilizations were not as isolated as traditionally thought and that transoceanic travel was possible, leading to connections between distant continents. This perspective aligns with his investigations and suggests that cultural exchanges and movement of peoples occurred over large distances, including potential migrations from Africa to the Americas.

His theories, while controversial and often debated, have played a significant role in encouraging further exploration and research into the capabilities of ancient seafaring peoples.
