Bering land bridge migration. Artwork showing the flow of human migration (red arrows) across the Bering land bridge (centre) from Asia (left) to North America (right). The Bering land bridge existed during the last ice age,around 18,000 years ago. Sea levels were lower at the time as much of the water on Earth was frozen at high latitudes due to lower average temperatures. Above the land bridge is the Arctic Ocean,below it is the Pacific Ocean | |
