Norwegian Thor Heyerdahl was a renowned anthropologist and explorer known for his groundbreaking expeditions, particularly the Kon-Tiki expedition in 1947. Heyerdahl set out to prove that ancient peoples could have crossed the Pacific Ocean on simple rafts, challenging prevailing theories about human migration patterns. His successful journey across the Pacific on a balsa wood raft reinforced the idea of cultural diffusion and the interconnectedness of civilizations across vast distances.
