site has the "earliest dated evidence for the use of domestic cereals in southwestern Asia" with a date range from approximately 9600 to 9475 BCE. It was noted that the number of specimens reported was low and their preservation was poor. Colledge assumed finds of domesticated barley (Hordeum vulgare) and wheat (likely Triticum turgidum dicoccum) were growing in secondary habitats. George Wilcox warned that the discovery of two grains of einkorn wheat at the site should be treated cautiously as anomalies to the general assumption that emmer was the only type of wheat used during the PPNA in the southern Levant. Graeme Barker has suggested that the spikelet forks and glume bases of domesticated wheat found were likely emmer. Studies have also been carried out on the fauna remains over the period of time between the Natufian and PPNA periods when hunter-gatherer groups first experimented with farming.
