The archaeological evidence for the Neolithic of the Levant, considered to have lasted from c. 8500 to 3750 B.C., is presented and an attempt made to explain its origins and development. The discussion is concerned with four principal themes: (1) the transition from a hunter-gatherer to a farming economy, (2) the social evolution that accompanied this economic development, (3) population growth immediately before and during the Neolithic and (4) the modifications in settlement patterns which followed these other changes. The environmental changes which occurred at the end of the Pleistocene and early in the Holocene are believed to be of fundamental importance. The degree of their influence on the four main themes is examined. The effects of man's own changing activities upon his environment are also considered. The Neolithic of the Levant is divided into four stages, designated Neolithic 1 to 4, on the evidence of changes in economy, population, settlement patterns and cultural remains. Regional groups of sites, defined by their cultural material, may be discerned and their evolution followed from one stage to the next. The detailed archaeological evidence is examined principally for the light it throws upon the development of the four main themes of the thesis and the contemporary changes in environment. It is argued that the amelioration of the environment in the late Pleistocene created a greater supply of wild foods for man which stimulated population growth. This was accompanied by increased sedentism and the development of agricultural techniques. In Neolithic 2 agriculture was intensified and the population grew further. After 6000 B.C. the population of the Levant lived in permanent settlements supported by agriculture but these were concentrated only in the more fertile and well-watered areas of the Levant. This new way of life permitted another increase in population in Neolithic 4 despite a deterioration in the environment.

This dissertation research examines variability in Natufian settlement and subsistence patterns. The Natufian is a late Epipaleolithic culture that flourished in the Levant during the late Pleistocene and early Holocene. There has been considerable research interest in the nature of Natufian settlement and subsistence over the last fifty years. This is due to the apparent pivotal position the Natufian holds in the developmental sequence from mobile hunting and gathering societies to sedentary village communities subsisting on domestic plants and animals. The research has two major components. The first aspect of the research focused on the range of activities and the nature of settlement intensity and duration during the Natufian occupation at one site, Beidha. The second aspect of the research entailed examining data for settlement and subsistence patterns throughout the Levant during this time period in order to gain insight into pan-Levantine variation. Research on the Beidha settlement has provided information on the range of chipped stone manufacturing processes carried out at the site, the nature of the tools produced, the range of activities that these tools imply, and the distribution of these elements between different areas of the site. The minimal evidence of spatial differences between provenience units is indicative of a site that was occupied as a relatively short-term camp site. The interpretation of the site as a short-term settlement, that was occupied repeatedly, fits with the lack of evidence for permanent features such as houses and storage facilities, as well as the lack of large groundstone objects and burials. Analysis of available data on Natufian settlement and subsistence has indicated that there are regional differences in settlement and subsistence patterns, most notably between steppe and desert sites versus sites of the forest and coast. In addition, there appear to be patterns in variability within the steppe and desert area with respect to the permanence of sites and the range of activities carried out in them. One set of sites is characterized by moderate settlement permanence and intensity, while the other set of sites is characterized by less permanent occupation and more specialized activity focused primarily on hunting.
