Previously, the Syrian plains were not considered as the homeland of Halaf culture, and the Halafians were seen either as
hill people who descended from the nearby mountains of southeastern Anatolia, or herdsmen from northern Iraq. However, those views changed with the recent archaeology conducted since 1986 by
Peter Akkermans, which have produced new insights and perspectives about the rise of Halaf culture. A formerly unknown transitional culture between the pre-Halaf
Neolithic's era and Halaf's era was uncovered in the
Balikh valley, at
Tell Sabi Abyad (the Mound of the White Boy). Currently, eleven occupational layers have been unearthed in Sabi Abyad. Levels from 11 to 7 are considered
pre-Halaf; from 6 to 4, transitional; and from 3 to 1,
early Halaf. No hiatus in occupation is observed except between levels 11 and 10. that spread to the other regions. ==Culture==
