The western Aleutians: Cultural isolation and environmental change

Recent research in the western Aleutians addresses two primary issues: the nature and extent of cultural exchange along the Aleutian chain, and Holocene environmental change and its effects on the development of Aleut culture. Cultural isolation is a major paradigm of researchers working in the Aleutians. Review of the distribution of several cultural traits suggests the Aleuts adopted many cultural elements originating outside the chain, but the distribution of these to the western islands was uneven.
