It's more than a hypothesis - it's supported by plenty of hard evidence. Eg, analysis of the oxygen content of mud in core-samples taken from below the Bering Strait conclusively shows that it was dry land for a period of many tens of thousands of years. During the last ice age, sea levels were at least 50m lower than they are today.
