low sea levels
According to the most recent research - sea levels were roughly 394 feet lower than they are now during the last ice age. After sea levels rose this caused areas, such as the land bridge between North America and Asia, to completely disappear beneath the ocean.
Sea levels rose over 300 feet.
Earth's seal levels drop during periods of glaciation, and are dependent on the amount of water locked away in the glacial ice.
A large proportion of Earth's surface water was in the form of ice and so sea levels dropped significantly.

The Irish Sea and the North Sea.
North America and Asia were connected by a land bridge called Beringia during the last ice age. This land bridge formed when sea levels dropped due to glaciers forming during the Pleistocene epoch.
During a glaciation: Sea-level falls (world-wide - the phrase "rising sea-levels", in the plural, you hear bandied about is rather silly). Consequently more land is exposed - albeit that a lot of it is covered in ice, with the tundra and sub-arctic areas moving to lower latitudes. During a warm interglacial (as now): Sea-levels rise, drowning previously exposed areas, though less of the land is buried under ice and the tundra fringes retreat Pole-wards. There isn't a "the Ice Age". An ice-age, such as the present one, is a series of alternating cold and warm phases.

The clasic theory is that people from northern Asia crosses the Bering Straights - possibly during an ice age (with low sea levels).
Sea level falls during ice ages because more water is locked up in glaciers.
