Other land bridges around the world have emerged and disappeared in the same way; approximately 14,000 years ago, mainland Australia was linked to both New Guinea and Tasmania, the British Isles formed an extension of continental Europe via the dry beds of the English Channel and North Sea, and the dry basin of the South China Sea linked Sumatra, Java and Borneo to the Asian mainland.
According to the standard accepted theory, the Clovis people crossed the Beringia land bridge over the Bering Strait from Siberia to Alaska during the period of lowered sea levels during the ice age, then made their way southward through an ice-free corridor east of the Rocky Mountains in present-day western Canada as the glaciers retreated.
