Unangan (Aleut) Migrations
Abstract There were diverse causes and demographic and evolutionary consequences of migration of the Unangan (a.k.a. Aleut) people in their expansion from Siberia through the Aleutian archipelago. The causes included subsistence patterns, volcanic eruptions that destroyed island econiches, climatic...
