added by archaeologs The part of the continental shelf that connects Northeast Asia with present-day Alaska. These were the polar continental shelves that escaped glaciation during the ice ages but which were exposed during periods of low sea level, which facilitated migration of people to North America from Asia, and in the Laptev and East Siberian seas. When exposed at the time of the last glacial maximum, it was a large, flat, vegetated landmass. In 1993, investigations on the climatic interstadial of 11,000-12,000 years ago in Beringia (now submerged under the Bering Strait) and the way it provided for the peopling of the New World from Asia were reported. Traces of starch from an apparently domesticated variety of the taro plant on flint tools from the Solomon Islands suggested that conscious planting was being done in the Pacific as long ago as 28,000 years before the present.
