Afro-Eurasia-America is a continuous landmass that exists during periods of low sea level induced by ice ages, and comprises about 85% of the Earth's land area when present in the current era.
It consists of the supercontinents of Afro-Eurasia, and the Americas, which in turn comprise Africa and Eurasia, and North and South America, respectively. These are joined by the Bering land bridge, or Beringia, during an ice age's glacial maximum, when the sea level is low enough for the area to become dry land. When this happens, some wildlife is exchanged. Beringia[edit] Shrinking of the Bering land bridge.
