The Central Zagros, due to its pioneering role in field research on the Neolithization process, played a fundamental part in shaping and presenting the initial theories concerning the origins of agriculture during the 1950s to 1970s. Among these theories, proposed by Kent Flannery, was the “Broad Spectrum Revolution,” which, in contrast to Robert Braidwood’s “Nuclear Zone” hypothesis, emphasized the significance of peripheral regions. Influenced by Lewis Binford and drawing upon archaeological evidence that he, together with Frank Hole, uncovered during the 1960s in the Khorramabad Valley and at Ali Kosh, Flannery argued that, due to population pressures in marginal areas such as the Deh Luran Plain, communities expanded their range of subsistence resources and consequently engaged in the domestication of plants and animals. Today, new evidence—not only from the Khorramabad Valley and Ali Kosh but also across the Central Zagros—provides grounds for reassessing and reinterpreting this theory. In recent years, the “Broad Spectrum Revolution” has continued to attract scholarly attention within archaeological discourse, influencing related models such as “Optimal Foraging Theory” and “Niche Construction.”
