 bridge joining Asia with Alaska in NA.

 nomadic hunters crossed this land bridge tracking
 herds of animals.
3- With the end of the last Ice Age temperatures 
 rose, glaciers melted and the land bridge
 disappeared under the Bering Strait.

 out and forced hunters to adapt turning to
 hunting/gathering and then farming for food.
