as chevrons, cross-hatchings and ladders. Some of the engravings closely resemble roughly contemporary European finds, and may be interpreted as "systems of notations" or "artificial memory systems" related to the timing of seasonal resources and related important events for nomadic groups. Similar looking signs and patterns are well known from the context of the local Natufian, a final Epipaleolithic period when sedentary or semi-sedentary foragers started practicing agriculture. The engravings found in Ein Qashish South involve symbolic conceptualization. They suggest that the figurative and non-figurative images comprise a coherent assemblage of symbols that might have been applied in order to store, share and transmit information related to the social activities and the subsistence of mobile bands. They also suggest a level of social complexity in pre-Natufian foragers in the Levant. The apparent similarity in graphics throughout the Late Pleistocene world and the mode of their application support the possibility that symbolic behavior has a common and much earlier origin.
