The best theories that explain people migrating from Asia to the Americas are the Coastal-route and Land-bridge theories. The "Land-bridge" theory refers to the Bering Land Bridge (Beringia), which connected Asia to North America during the last Ice Age when sea levels were lower. The "Coastal-route" theory suggests that people also migrated along the coastlines, using boats or following marine resources. Both theories are widely accepted in explaining human migration to the Americas.
