• Human remains found in North America 13,000 years ago are closely related to tribes from Asia; more specifically - Siberia
Theory #2:Pacific Ocean Migration
Pacific Ocean Migration• Thor Heyerdahl
– Despite losing all of his academic credentials, Thor Heyerdahl believed that South America became populated by humans migrating in rafts across the Pacific Ocean.
• Kon Tiki Raft – sailed in 1947 from South America to Polynesia in the Pacific and then back again to South America. DNA suggest possible migration.
