<P> The Strait has been the subject of the scientific hypothesis that humans migrated from Asia to North America across a land bridge known as Beringia when lower ocean levels -- perhaps a result of glaciers locking up vast amounts of water -- exposed a wide stretch of the sea floor , both at the present strait and in the shallow sea north and south of it . This view of how Paleo - Indians entered America has been the dominant one for several decades and continues to be the most accepted one . Numerous successful crossings without the use of a boat have also been recorded since at least the early 20th century . </P>
