The Kebaran was an archaeological culture in the eastern Mediterranean area (c. 18,000 to 10,000 BC), named after the type site, Kebara Cave south of Haifa. The Kebaran were a highly mobile nomadic population, composed of hunters and gatherers in the Levant and Sinai areas who utilized microlithic tools. The Kebarans were characterized by small, geometric microliths, and were thought to lack the specialized grinders and pounders found in later Near Eastern cultures. The Kebaran people were believed to practice dispersal to upland environments in the summer, and aggregation in caves and rockshelters near lowland lakes in the winter. This diversity of environments may be the reason for the variety of tools found in the toolkits. Being situated in the Terminal Pleistocene, the Kebaran is classified as an Epipalaeolithic society. They are generally thought to have been ancestral to the later Natufian culture that occupied much of the same range. http://en.wikipedia.org/wiki/Kebaran
The Natufian culture existed in the Mediterranean region of the Levant. It was a Mesolithic culture, but unusual in that it was sedentary, or semi-sedentary, before the introduction of agriculture. The Natufian communities are possibly the ancestors of the builders of the first Neolithic settlements of the region, which may have been the earliest in the world. There is no evidence for the deliberate cultivation of cereals, but people at the time certainly made use of wild cereals. Animals hunted include the gazelles.
