The Levantine Epipalaeolithic, c. 20,000–10,000 BP, represents one of the most intensively studied periods in prehistoric research in the past 30 years, with literally hundreds of sites being discovered and many systematically investigated. The researchers involved come from a diverse range of backgrounds and national 'schools', and include American, Australian, British, French and Israeli scholars. Some, myself included, see its variability in chipped stone tool morphology, techniques of manufacture and specific means of hafting to reflect, in addition to functional factors, the stylistic traditions of specific groups in the landscape (Bar-Yosef 1991a; Goring-Morris 1987; 1995). This evidence is further bolstered by chrono-stratigraphy, settlement patterns, inter- and intra-site organization and patterning, as well as other material culture residues (Goring-Morris 1989a; 1989b; 1991).
