Beyond this region, however, in the foothills of the Alborz Mountains of north-eastern Iran, evidence has emerged that charts the Neolithic transition over a period of 1500 years. Investigations at the twin mounds of Tappeh Sang-e Chakhmaq have revealed pre-pottery and pottery Neolithic occupation in a sequence long enough to document the evolving exploitation of plants and animals leading to the development of a permanent, agro-pastoral community during the eighth to sixth millennia BC. The continuous occupation of this settlement during this crucial transition allows significant changes in lifestyle to be mapped, and provides a new framework for the earliest Neolithic occupation of Iran.
