The earliest attested archaeological artifacts in Iran, like those excavated at Kashafrud and Ganj Par in northern Iran, confirm a human presence in Iran since the Lower Paleolithic. Iran's Neanderthal artifacts from the Middle Paleolithic have been found mainly in the Zagros region, at sites such as Warwasi and Yafteh. From the 10th to the seventh millennium BC, early agricultural communities began to flourish in and around the Zagros region in western Iran, including Chogha Golan, Chogha Bonut, and Chogha Mish.
