Food storage is a vital component in the economic and social package that comprises the Neolithic, contributing to plant domestication, increasingly sedentary lifestyles, and new social organizations. Recent excavations at Dhra' near the Dead Sea in Jordan provide strong evidence for sophisticated, purpose-built granaries in a predomestication context Ϸ11,300 -11,175 cal B.P., which support recent arguments for the deliberate cultivation of wild cereals at this time. Designed with suspended floors for air circulation and protection from rodents, they are located between residential structures that contain plant-processing instillations. The granaries represent a critical evolutionary shift in the relationship between people and plant foods, which precedes the emergence of domestication and large-scale sedentary communities by at least 1,000 years.Near East ͉ Neolithic ͉ forager-farmer transition N ew archaeological work at the PPNA (Pre-Pottery Neolithic A; Ϸ11,500-10,500 cal B.P.) site of Dhra', located next to the Dead Sea in Jordan, reveals clear evidence for large-scale storage in sophisticated, purpose-built granaries before the domestication of plants. Evidence for PPNA food storage illustrates a major transition in the economic and social organization of human communities. The transition from economic systems based on collecting and foraging of wild food resources before this point to cultivation and foraging of mixed wild and managed resources in the PPNA illustrates a major intensification of human-plant relationships.People in the PPNA were the first in the world to develop systematic large-scale food storage. In the Early Natufian period (Ϸ15,000/14,500-12,800 cal B.P.), people used a remarkably wide range of wild plants and animals, lived in relatively large well-made semisubterranean buildings for much of the year, and undoubtedly had a detailed knowledge of the seasonality and availability of these resources (1). Certainly the apparent increased degree of sedentism in the Early Natufian period suggests that people were able to reduce seasonal food risks to the point where they could live in the same areas for 1 or more seasons of the year. There is, however, surprisingly little direct evidence for food storage (2, 3). The strongest is from 'Ain Mallaha (4), where pits are often termed silos although their specific function is unclear. There is indirect evidence in the Natufian for plant food processing, including the presence of sickles, mortars, and pestles. Although Natufian people probably engaged in some form of low-level food storage, they also situated their settlements where they were able to use high-yield food resources from multiple natural ecotones in different seasons. With the onset of the climatic downturn of the Younger Dryas, people in the Late Natufian period (Ϸ12,800-11,500 cal B.P.) returned to more mobile economic and subsistence strategies. Late Natufian people abandoned earlier settlements, adopted new systems seasonal residential movement, and rarely built residential structu...
