To what extent do hunter- gatherers, for-agers, and farmers differentially create anduse space within settlements? If the social

Exploring the Social Use of Space and the Forager- Farmer Transition

In the context of the prehistoric Near East, the path-ways to fully sedentary communities from rela-tively mobile foragers were multibranched withpeople living in conditions of reduced residentialmobility and then reverting back to more mobilelife ways (Belfer- Cohen and Bar- Yosef 2000;Henry 1991). The Epipaleolithic of the Near Eastis divided into a number of temporal and culturaldivisions (Table 1).

residing in a settlement for the majority of the year,first appeared in the late Epipaleolithic during theEarly Natufian tradition (14,500–12,800 cal B.P.) (Belfer- Cohen and Bar- Yosef 2000; Hardy- Smithand Edwards 2004; Lieberman 1993) but may havehad much earlier roots in Early Epipaleolithic (cf.the occupation at Ohallo II see Nadel et al. 1995,2006). While Early Natufian communities thrivedfor approximately 1,500 years, the degree of seden-tism declined for the following millennium duringthe Late Natufian. People eventually shifted togreater residential permanence during the EarlyNeolithic starting around c. 11,500 years ago (Belfer- Cohen and Bar- Yosef 2000; Grosman2003:572; Kuijt and Goring- Morris 2002; Twiss2007). Early Natufian societies are often characterized

as complex hunter- gatherers with the associatedcharacteristics of social organization and economicintensification (Bar- Yosef 2002; Belfer- Cohen and Bar- Yosef 2000; Goring- Morris and Belfer- Cohen1998). After the Early Natufian, Late Natufian pop-ulations appear to be more typical mobile hunter- gatherers with increased residential mobility (Bar- Yosef 1998:168, 2002:129–131; Goring- Morris and Belfer- Cohen 1998:80–82; Munro2004). Early Neolithic communities, and morespecifically, those of the Pre- Pottery Neolithic Aperiod, are broadly characterized as being complex forager- collectors, with elaborate chipped andground stone tool technology, and living in moreelaborate residential communities. While there is noquestion that these groups were engaged in variouslevels of wild plant manipulation, researchers gen-

erally agree that there is no systematic evidence forthe appearance of domesticated plants at this point.Discussion of the broad evolutionary shifts from

the Natufian to the early Neolithic has largely cen-tered on: (1) climatic change and the onset of coldand dry conditions of the Younger Dryas (e.g. Goring- Morris and Belfer- Cohen 1998), (2) thefragility of complex social frameworks (Belfer- Cohen and Bar- Yosef 2000:23–24) and, (3) popu-lation dynamics (Henry 1989). Beyond such broadevolutionary considerations, researchers havestarted to develop detailed understandings ofchanging practices of lithic technology within andbetween different stages of the forager- farmer tran-sition (e.g. Belfer- Cohen 1994; Belfer- Cohen and Goring- Morris 1996). There are, however, surpris-ingly few studies that have explored the degree ofspatial variation of lithic tools and technologywithin occupation phase, let alone between differ-ent phases of occupation of the same settlement. Inthis paper we argue that such studies can signifi-cantly contribute toward our understanding ofbroader, and largely unrecognized, patterns in gen-eral, and more specifically, help us identify signif-icant changes in the ways in which spaces wereused within settlements, practices were material-ized, and how settlements were structured throughhuman action.We believe that intra- site patterning, specifically

the spatial variability in cultural materials, can beused to track some of the shifts in intra- communityorganization. We identify two trends; first, anincreased formalization in the use of space throughtime, and second, the clear separation of the spa-

Debate exists as to the existence andpotential time span of an Early PPNB phase. It is not at all clear, however, if such a cultural-historical construct is supportedby archaeological data. While recognizing the historical precedent of the EPPNB phase, researchers have yet to demonstratethat practices within Early PPNB communities were significantly different from Middle PPNB communities.

tial organization of practices, such as the locationof flintknapping, refuse disposal, and where selectactivities occurred. These patterns reflect the vari-able pulses of changing settlement systems. At thebroadest level we argue that intra- community orga-nization during the Early and Late Natufian wasdifferent from those of early Neolithic communi-ties. To make this argument we draw upon data fromthe site of Iraq ed- Dubb, Jordan (Kuijt 2004; Kuijtand Goodale 2006). The site contains occupationsfrom the last hunter- gatherer/forager populations(Late Natufian) to some of the earliest relativelysedentary collector/agriculturalist communities (Pre- Pottery Neolithic A) in the Near East. Utiliz-ing the lithic remains from the Late Natufian and Pre- Pottery Neolithic A (or PPNA from here for-ward) occupations of ‘Iraq ed- Dubb, we worktoward a quantifiable statistical approach incorpo-rating Geographic Information Systems analysis.This enables us to document and better understandchanging systems of how people used space andthe variability accompanying these occupations.On this basis, we argue that the Late Natufian peo-ple were relatively mobile and had fairly nonde-lineated use of space compared to a more delineateduse of space during the PPNA. With corroboratingevidence from published literature on intra- community organization from Early Natufian andPPNA sites, we argue that intensified intra- community organization of space occurred hand inhand with decreased residential mobility. Whilethere is variation, it appears that the emergence ofa higher degree of formal intra- community orga-nization likely aided in the development of muchmore complex human societies that evolved sev-eral millennia after the onset of Holocene conditions.Even though mixing will have occurred between

stratigraphic layers, the use of well- established cul-tural historical understandings of lithic typology incombination with confirmatory and exploratorydata analysis statistical methods, allows us to sep-arate assemblages from the multicomponent sitewith a complex stratagraphic record. While thereare some technological similarities between thesetwo time periods, at the same time there are sev-eral distinct tool types for different period tool kitsthat make it possible to separate different occupa-tion periods (Belfer- Cohen 1994; Belfer- Cohenand Goring Morris 1996).

Archaeological Background

The Near Eastern archaeological record of the LateEpipaleolithic (14,500—11,700 cal B.P.) (Table 1)of the southern Levant is relatively well understoodbut highly complex. The changes we are concernedwith in this paper occurred in the geographic areaapproximately incorporating Mount Carmel, theGalilee, and the Jordan Valley, broadly known asthe “Natufian Homeland” or “core Natufian area” (Bar- Yosef 1998; Hardy Smith and Edwards2004:257; Valla 1998). According to Bar- Yosef(1998:68), Early Natufian tradition (14,500–12,800cal B.P.) hamlets in the “Homeland” are viewed asa “reaction to an abrupt environmental change thatnecessitated a shift of resource scheduling.” Thisgeneral improvement in climate, referred to as the Bölling- Alleröd interstadial (Baruch and Bottema1991), is an environmental shift to warmer and wet-ter conditions just before the end of the last glacialmaximum (Bar- Yosef 2002:106). With the onset ofthe Younger Dryas, a recognized global climaticepisode of cold and dry conditions (Kudrass et al.1991), Late Natufian (12,800–11,700 cal B.P.) peo-ples reverted to more mobile settlement systems,possibly as an adaptation to shrinking resourcepackages (Bar- Yosef 1998:168, 2002:129–131; Goring- Morris and Belfer- Cohen 1998:80–82).Evidence of stress among Late Natufian popula-tions (Bar- Yosef 1998; Belfer- Cohen et al.1991:421–422; Smith et al. 1984) and the subse-quent reversion in the Late Natufian to higher res-idential mobility and smaller group size (Bar- Yosef1998; Belfer- Cohen and Bar- Yosef 2000; Goring- Morris and Belfer- Cohen 1998), were likely sig-nificant contributions to how people adjusted theirsettlement strategy to cope with changing social andnatural environments. After the Younger Dryas, PPNA (11,700–10,500

cal B.P.) peoples established relatively sedentarycommunities in the southern Levant with anincreased reliance on plant foods (Bar- Yosef 1998;Byrd 2005; Kuijt and Goring- Morris 2002; Twiss2007). These communities, possibly under theinfluence of ideas from the northern Levant, werelater replaced with new larger villages that housedseveral hundred people during the Middle Pre- Pottery Neolithic B (MPPNB) (Gebel 2002; Rollef-son 1998, 2004). At the end of the PPNB, the largevillages of the Late PPNB collapse and people

opted for a more mobile lifestyle focused on ani-mal husbandry characterized by ephemeral and/orreused PPNB architecture (Kuijt 2000; Rollefson1998:116).

‘Iraq ed- Dubb

‘Iraq ed- Dubb is located approximately 7 km north-west of Ajlun, Jordan. The cave of ‘Iraq ed- Dubbis one of several caves and rock shelters along alimestone escarpment 150 m above the extensivelyvegetated part of the Wadi el- Yabis (Figure 1). Thesite encompasses approximately 150 m2within the

cave and likely doubles this amount on the terraceat the mouth of the cave. Although natural andanthropogenic processes have mixed some of thecultural sediments, dating of intact deposits haveindicated that the upper deposits with structuresdate to the PPNA and the underlying deposits andthose extramural to the structures largely date tothe Late Natufian. The site was excavated for threefield seasons and in total recovered two oval stonestructures, multiple pit features, fire hearths, andburials (Figures 2 and 3) (see Kuijt 2004 for adetailed description of features and architectural

elements). All of these artifacts were situated withinless than 1.5 m of vertical cultural fill and most ofthe excavation units were taken to bedrock. Eachstructure was 4 to 5 m in diameter and had mudplaster floors. Structure I was almost entirely exca-vated, and had multiple episodes of mud floor- plastering events and an internal fire hearth.Beneath Structure I were several Late Natufianadult and subadult burials. All of the burials lackedgrave goods and were placed in small hollowsbetween bedrock outcrops (Kuijt 2004). StructureII had large grinding and anvil stones inset into thefloor with a stone collar foundation and a central10 to 15 cm circular mud platform.The site of ‘Iraq ed- Dubb is one of only a few

sites in the Mediterranean Zone identified with bothLate Natufian and PPNA occupations containing well- dated sediments attributed to both periods(Kuijt 2004; Kuijt and Goodale 2006). Because theexcavations at ‘Iraq ed- Dubb provide a clear exam-ple of the transition from Late Natufian to PPNAadaptive strategies, this study addresses the role oflithic tools and use of space during this change insettlement systems. While illuminating the char-acteristics of both the Late Natufian and PPNAlithic assemblages, this study will set the lithic tech-nology into broader anthropological questions ofsettlement, intra- community organization, and res-idential mobility within the Late Natufian andPPNA occupations of ‘Iraq ed- Dubb.

Analysis and Interpretation of the ‘Iraq ed- Dubb Chipped Stone Industry

During the excavation of ‘Iraq ed- Dubb, approxi-mately 50,000 lithic artifacts were recovered includ-ing high percentages of tools indicative of the LateNatufian and the PPNA (Table 2). The tool assem-blage is comprised of 1,102 artifacts, which are thefocus of this study. The datasets representing bothLate Natufian and PPNA loci (as defined in Table2) contain approximately the same number of toolsand tool types, suggesting that our patterns are notinfluenced by richness and/or diversity. Moreover,due to space limitations in this study we are onlyaddressing the spatial patterns and different activi-ties associated with stone tools. Future research willfocus on debitage analysis. Lithic artifacts wererecovered from 32 loci. As seen in Figure 4, Areas1 and 3 contained most of the lithic tools while Area2 contained far less. This pattern is in part due tothe depth of excavation where sediments werelargely left intact below the floor of Structure II/Area2, while Areas 1 and 3 were excavated to bedrock.Tool types include various nongeometric/geomet-ric microliths, El- Khiam and Salibiya projectilepoints, Hagdud truncations, scrapers, burins, per-forators, sickle blades, bifacial tools, variousretouched blades, bladelets, and flakes (see Kuijt andGoodale 2006 for a comprehensive description ofthe chipped stone from ‘Iraq ed- Dubb).

Normative typological analysis is the mainmethod used to document late Pleistocene and earlyHolocene Near Eastern lithic tool assemblages.Despite considerable field research there is on- going debate among archaeologists as to which tooltypes are characteristic of individual cultural- historical periods (see Belfer- Cohen 1994; Belfer- Cohen and Goring- Morris 1996; Finlayson et al.2003; Garfinkel 1996; Nadel 1997:133–134 foroverviews of the problem). The tool types that areimportant in this debate are microliths (both non-geometric and geometric forms), projectile points(both el- Khiam and Salibiya forms), truncations(both Hagdud and Gilgal forms, however, only Hag-dud truncations are present in the ‘Iraq ed- Dubbassemblage), and large, heavy utility biface picks,axes, and chisels (Figure 5). Researchers differ asto which tool types are, or are not, characteristic ofdifferent periods. In our analysis we have eliminatedspecific tools for analysis, and are not employingbifaces as a key to detecting PPNA assemblages.This is not to reduce their importance, but given thatonly three bifaces were found at the site (Table 2)they are not a major data set for analysis. We havenot included them in the chi- square analysis belowdue to the minimum sample size expectations of N> 5. However, because they are crucial to defininga PPNA lithic industry, they are utilized in the otherpattern recognition and exploratory statistical testsprovided later. Additionally, all of the bifaces were

found in association with PPNA sediments or thosethat were likely disturbed by the PPNA occupation.While it is generally accepted that Hagdud trunca-tions, and el- Khiam and Salibiya point types werenew inventions that are temporally restricted to thePPNA, researchers continue to debate if microlithswere continually manufactured from the Natufianfor 300–500 years into the Neolithic. Nonetheless,

it appears that microlithics at least drop signifi-cantly (Yartah 2002), if not completely (Garfinkel1996; Finlayson et al. 2003; Kuijt and Goodale2006) out of the PPNA lithic tool kit by the earlyPPNA and their presence is likely due to mixing.In other words, significant percentages ofmicrolithics should be indicative of Natufian com-ponents.

Illustrating Two Disparate Occupations

In light of the debate on inter- assemblage vari-ability, it is necessary to address site scale variabilitythrough time before exploring how these data helpus understand the behavioral components that theposition of these artifacts may represent in the largerissue of the forager/farmer transition. To clarify theextent to which different tool types overlap, thenext section of the paper attempts to assign the lociaffiliated with each of the two occupations at ‘Iraq ed- Dubb. The 14C data shown in Figure 6 illustratea clear hiatus of ca. 550 years between the LateNatufian and PPNA occupations. To analyze thechronological separation of different diagnostictool types, we utilize both horizontal and verticalrelationships and consider the presence and/orabsence of certain tools types in different occupa-tional zones. To understand some of the detailed dimensions

of variability and how this fits with cultural- historical sequencing, we explore some of the spa-tial patterning of diagnostic artifacts. First, does thespatial occurrence of lithic tool types attributed tothe Late Natufian and the PPNA illustrate spatialpatterning horizontally across the site? Formally,the question is: can we elucidate differences withrespect to tool typologies that are expected to berestricted to either the Late Natufian or the PPNAon a horizontal scale? Figure 2, which depicts theoverall pattern in Area 2, illustrates that the inte-rior of Structure II exhibits a very high count of

truncations and very few geometric microliths. Thisfits well with the radiocarbon dating that assignsthis structure to the PPNA period (Kuijt 2004).Area 3 shows a very high percentage of geometricmicroliths indicative of a Late Natufian occupation.Area 1 contains a mixture of tool types associatedwith both periods. These initial results supportinterpretations that Areas 2 and 3 were discreteoccupations containing tools representative of aLate Natufian occupation in Area 3 and a PPNAoccupation in Area 2 (see Kuijt and Goodale 2006for a comprehensive analysis). Second, do the patterns in Structure I exhibit a

Late Natufian versus a PPNA signature on a verti-cal scale? As demonstrated in Figure 7, the sequenceof vertical deposition reveals that the lower strati-graphic levels (green) contain a high number of geo-metric microliths with some intrusive PPNA tools.The middle levels, most likely to have been mixedby the construction and re- building of Structure I(blue), are characterized by declining numbers ofgeometric microliths with increased numbers ofprojectile points and Hagdud truncations. In theupper levels (red), there is a decrease in microlithsand high quantities of PPNA tools. However, thereare still some microliths in the upper level. Webelieve the occurrence of the microliths are linkedto site formation processes where earlier tool formswere mixed during the construction of the laterPPNA structure floors. The fact that it is very evi-dent that some PPNA tools have changed in theirvertical position supports this view.

Finally, can we determine if these spatial pat-terns are statistically significant? To demonstratethis we examined the stratigraphic layers utilizedin both the vertical and horizontal analysis by divid-ing them into Late Natufian (Area 3; green), mixed(Area 1; blue), and the PPNA (Area 2 and Area 1;red) as the independent variable and tool type (geo-metric microlith, projectile point, and Hagdud trun-cation) as the dependent variable. As demonstratedby chi- square analysis, these patterns are statisti-cally significant (�2 = 229; df = 4; p = <.0001; �R �C = .3053). While these results clarify the rela-tionship of certain tool types present in an overallpicture of the excavation area and indicate whatareas were likely utilized during the Late Natufianand the PPNA, they do not allow for further exam-ination of how lithic tool kits may help to identifycertain aspects of settlement organization such asthe existence of spatially delineated activity areas.To accomplish this we employ exploratory dataanalysis and confirmatory data analysis techniquesto extract patterns of tool variability in spatiallyrestricted areas at ‘Iraq ed- Dubb. The subsequentanalysis presented below demonstrates that we can

statistically define the tool kits of the Late Natu-fian and the PPNA to make interpretations on howthe site was structured differently through the tran-sition from the Late Natufian to PPNA.

Identifying Distinctive Tool Assemblages

To address spatial organization we utilizeexploratory data analysis (EDA) and correspon-dence analysis (CA) to detect overall patterns oflithic data and to evaluate evidence for a subdivi-sion of tools between each occupation. Second, weemploy a more confirmatory data analysis tech-nique, discriminate analysis (DA), to statisticallytest the results of the correspondence analysis andverify the patterns of the two cultural occupationsthat we can then interpret. The lithic data for this study were obtained

from 32 loci encompassing two structures and anextramural area from approximately 1.5 m of cul-tural sediments. The data used are representativeof all lithic tools (Table 2) found in associationwith all loci excavated during the 1989–1991 sea-sons. We did not analyze the materials recovered

CA is an analysis technique wheredata can be represented in a Euclidean coordinatesystem that is very similar to principal componentsanalysis (PCA) (Shennan 2001). Shennan(2001:308) notes that while PCA provides the foun-dations of to the CA technique, PCA is not suitedfor the analysis of data consisting of numericalcounts. Conversely, CA is specifically designed fordirect measurement data such as counts of lithic tool

types or ceramic sherds, which arguably is the mostcommon type of data in archaeology. CA providesa scatter plot in Euclidean distance illuminatingpatterns in numerical data that reflect relationshipsbetween cases and variables. CA was originallydeveloped in France and gained the appreciationof French archaeologists (Djindjian 1985), Scan-dinavian archaeologists (Madsen 1988), and laterof North American archaeologists focused on theSouthwest ceramics (Duff 1996).

the data within a variable to be normally distrib-uted to extract patterns of variability. The CA was run in the statistical program SAS

v. 8.0 with the data at the locus level presented inTable 2 (see Figure 8). Several interesting patternsemerge from this analysis. First, geometricmicroliths, nongeometric microliths, cores, burins,and scrapers exhibit negative loadings on Dimen-sion 1. Dimension 1 also provides positive load-ings on Hagdud truncations, projectile points,perforators, backed blades, retouched blades,notches and denticulates, sickle blades, and bifa-cial tools. We interpret Dimension 1 to reflect diff -erent periods of occupation, clearly dividing thediagnostic tool types associated with the Late Natu-fian period (geometric microliths and nongeomet-ric microliths), from those associated with PPNAperiod assemblages (projectile points and Hagdudtruncations).

Second, Dimension 2 is primarily responsiblefor the vertical distribution on the graph of the toolsand loci where those associated with the left quad-rants are tightly clustered with the juxtaposed dis-persed pattern on the right. Dimension 2 separatesLate Natufian loci that have negative loadings ongeometric microliths, nongeometric microliths, andcores in Quadrant 1 from those with positive load-ings on scrapers and burins in Quadrant 2. Dimen-sion 2 also separates PPNA loci having negativerelationships with projectiles, truncations, perfo-rators, and backed blades (Quadrant 3) from thosewith positive relationships including retouchedblades, notches and denticulates, sickle blades, andbifaces (Quadrant 4).As mentioned, this graph depicts a tight clus-

tering of what are likely Late Natufian period lociand tools compared to the PPNA period disperseddistribution. While this patterning can be inter-

preted from multiple perspectives, one interpreta-tion is that Late Natufian and Pre- Pottery NeolithicA period groups organized and used space in verydifferent ways. In contrast to the more formal useof space during the Pre- Pottery Neolithic A period,the Late Natufian people did not restrict their activ-ities to specific spatial areas of the cave. Nearlyevery locus of the Late Natufian occupation showsthe occurrence of the entire range of typologicalvariability. In contrast, the loci affiliated with thePPNA are much more spread out with each locusmore likely to be different from the next suggest-ing formal activity areas where certain tasksoccurred. We suggest that this pattern reflects anintensified degree of PPNA period site organiza-tion and the formalization of specific activity areasassociated with decreased residential mobility.When we plot the CA results in vertical and

horizontal loci blocks from ‘Iraq ed- Dubb (Figure9), we see the relationship between loci and toolsthat are roughly comparable with the quadrant colorscheme in Figure 7. All of the areas contain sig-nificant correlation to the Late Natufian within theupper most layer (locus 001). PPNA people do notappear to have used the areas extramural to theirsemisubterranean structures. It is not clear why thisis the case; perhaps this is a function of shortnessof the occupation or that major activities occurredout front of the rockshlelter. The lower levels ofStructure II contain significant proportions ofretouched blades, sickle blades, notches and den-ticulates, and bifacial tools (Figure 9, A- A’ crosssection), which is consistent with the PPNA dateof 11,210–11,710 cal B.P. (p = .95) (Kuijt2004:295, AA-38145; wood charcoal �13C =–25.2‰). (Calibrated at 2� with the programOxCal 3.10 [Ramsey 1995, 2001].) Structure I con-tains significant proportions of tools associatedwith Quadrants 3 and 4 (Figure 7) in loci 003, 005,007, 014, 016, and 023 representing floors and fea-tures associated with the structure. Locus 010, thesecond floor in Structure I, is anomalous, with asignificant proportion of tools associated with theLate Natufian. Supported by the stratigraphicsequence of the rebuilding of Structure I, this anom-aly may be explained by the use of earlier depositscontaining Late Natufian tools to construct or levelthe PPNA floor of Structure I during the secondoccupation and/or rebuilding (represented as Locus007). The lower levels within Structure I, not actu-

ally associated with the structure, contain a signif-icant proportion of tools indicative of the Late Natu-fian. All of the extramural units have a significantnumber of tools associated with the Late Natufian,depicting the spatial constraint of the two occupa-tions.

Discriminant Analysis

In contrast to correspondence analysis, discrimi-nant function analysis (DA) presupposes the exis-tence of a given number of known groups and isconcerned with the allocation of cases that are col-lections of items to those groups to which theybelong most appropriately (Shennan 2001:350).Briefly, DA plots the case membership in rela-tionship to a centroid in a plot where the axes rep-resent the discriminant functions that characterizethe major dimensions of variation that differenti-ate groups allowing interpretation of the dimen-sions (e.g., temporal, spatial, or physical attributevariability) in a similar manner as CA (Shennan2001). To our knowledge, DA has been in use inarchaeology since the late 1970s (e.g. Bettinger1979). While this technique has not been appliedto Near Eastern prehistoric questions, the follow-ing discussion illustrates the utility of DA in con-firming the patterns presented by the CA.As DA assumes normality, each variable was

transformed with LOG10 to correct for the positiveskewness exhibited by each variable. Prior to tak-ing the LOG10, a small constant (.01) was added toeach value to avoid null values for the transforma-tion. As DA presupposes case membership to agroup, each locus was grouped intuitively into oneof the following classifications: Area 1: fill, firstfloor, second floor, or subfloor; Area 2: fill, floor,or subfloor; and Area 3. The analysis was run inSAS v.8.0 with the data provided in Table 2 by theintuitive groupings stated above. The maximumtwo discriminant functions were utilized explain-ing 71 percent of the variability. Both of the dis-criminant functions were statistically significant(�2 of Wilk’s lambda: p < .0001) as were the dif-ferences between all seven intuitive clusters as mea-sured by discriminant functions 1 and 2 (F- ratio ofcentroids: F < .0001 and F < .0015 respectively).The overall trend is highlighted by the DA is

most apparent when both functions are exploredsimultaneously. Both functions explain nearly thesame percentage of variability with 36 percent and

35 percent respectively. This confirms that the ovaltrend in Figure 9 is meaningful, which separatesthose loci affiliated with Area 3 and Area 1/ Struc-ture I subfloor in Quadrant 2 from the loci affili-ated with the PPNA occupation of Structures 1 and2 shown in Quadrants 1, 3, and 4. The pattern inQuadrants 1, 3, and 4 are very different from Quad-rant 2, indicating, again, as with the CA, that adiversity of discrete activity areas highlight PPNAoccupation while homogeneous activity areasbelong to the Late Natufian. In both the DA andCA analyses, geometric and nongeometricmicroliths were identified as contributing to cer-tain loci more consistently than others, while the

scattered distribution of the majority of the toolsappears to reflect the PPNA occupation.

Discussion

Our analysis and interpretation is complicated bythree factors. First, there are very few known Epi-paleolithic and Neolithic sites that bridge the LateNatufian/PPNA culture history periods (a very sig-nificant period linked to the forager- farmer transi-tion). Second, many Levantine Natufian andNeolithic sites were excavated before the intro-duction of systematic high- resolution dry sievingand flotation (Bar- Yosef 1998:166). In the excava-

tion of Jericho, for example, no sieving wasemployed. Third, even when sieving was employedin excavations, subsequent analysis of Late Natu-fian and Neolithic sites are undermined by othercomplications. For example, there are a limitednumber of sites that have been excavated with ade-quate recording to conduct this type of analysis, andeven fewer that have been subsequently publishedin a manner that allows comparisons. Finally, andunquestionably the most challenging of these fac-tors, researchers have yet to identify the degree towhich human practices are, or not, systematicallypatterned within settlements. The analysis of the‘Iraq ed- Dubb materials provide an initial meansto explore the changing degree of intra- communityorganization and inter- community relationships(e.g., Bar- Yosef 2002; Belfer- Cohen and Bar- Yosef2000; Henry 1989). In concert with a detailed understanding of

changing diagnostic tools through time, the spatialpatterning of artifact deposition can help us under-stand aspects of community organization during the forager- farmer transition, highlighting shifts inbehavioral adaptations, and help us reconstruct theuse of delineated and non- delineated activity areas.Excavations at select Natufian sites illustrate aninteresting binary pattern of use: well- defined loca-tions, such as inside structures, and other areas thatare relatively homogenous (Hardy- Smith andEdwards 2004; Valla 1988). Hardy- Smith andEdwards (2004) argue that at the Early Natufian siteof Wadi Hammeh 27 (Edwards 1991) the inhabi-tants “had not tailored their indifferent householdsanitation practices to the long- term requirementsof sedentary living” (Hardy- Smith and Edwards2004:285). To substantiate their interpretation theynote that 82 percent of 423,858 flake stone artifactswere recovered from inside two structures with theremaining 18 percent recovered extramurally. Thestructures’ interior volumetric densities of flint arti-facts reach 4,669 m2. They argue that while therewere apparent activity areas, activities were “car-ried out against the generalized backdrop of every-day domestic duties, rather than in speciallyallocated areas or purpose- built buildings” (Hardy- Smith and Edwards 2004:277). They also suggestthat this pattern is seen at other sites occupied dur-ing the Early Natufian including Hayonim Cave (Bar- Yosef 1991; Belfer- Cohen 1988), the associ-ated Hayonim Terrace (Henry et al. 1981), and Ain

Mallaha (Valla 1988, 1991). While having a lowerdensity of artifacts and no permanent structures, thepattern from the Late Natufian occupation ‘Iraq ed- Dubb is strikingly similar to that Early Natu-fian occupation at Wadi Hammeh 27.Nadel (1998:8) argues that the spatial pattern

from Late Epipaleolithic settlements is relativelyhomogenous, and that nearly every archaeologicallocus contains the full gamut of typological vari-ability. With the Late Natufian occupation at ‘Iraq ed- Dubb, we see that everyday activities occurredin all areas of the site, and this has contributedtoward a material homogenization of the toolsrecovered from individual loci. As such, the LateNatufian occupation(s) at ‘Iraq- ed- Dubb appear tohave had similar intra- community spatial organi-zation, practices that resembled those of the pre-ceding Early and Middle Epipaleolithic periods.Some of this patterning may be related to theabsence of significant site furniture in the LateNatufian. Hardy- Smith and Edwards (2004:282)and Binford (1983:152–153) argue that under spe-cific conditions, different types of site furniture,such as fire hearths, are likely to produce drop zonesand spatial concentrations of materials. Echoingthese general observations, the evidence from “Iraq ed- Dubb illustrates how Late Natufian peoples”practices were characterized by comparably lessspatial segregation of activities, while PPNA pop-ulations appear to have carried out more formal-ized practices.A number of recent studies, including that of

Hodder and Cessford (2004), have drawn attentionto the increasingly structured use of space andrefuse management within large Neolithic villages.As one of the few available detailed studies, thisallows us to look at the end of what must have beena long- term trajectory starting in the Epipaleolithicperiods. At the moment, however, we have only alimited understanding of how and why the use ofspace shifted through the forager- farmer transition.Excavations at other PPNA sites provide hints ofthis transition. Further evidence for PPNA delin-eated activity areas and refuse management prac-tices comes from the recently excavated site ofDhra’, Jordan (Finlayson et al. 2003; Goodale etal. 2002; Kuijt 2001), and Wadi Faynan 16 (Fin-layson and Mithen 2007). At Dhra’, specific refusemiddens were found as well as overall smaller den-sities of lithic artifacts on cleaned floors and occu-

pation surfaces. Other excavations at PPNA sitesof Netiv Hagdud (Nadel 1997:126) and QermezDere (Watkins 1990) are inconclusive, but this maybe due to limited sampling and excavation of rela-tively shallow areas. At Netiv Hagdud, for exam-ple, the limited excavation, both vertically andhorizontally, has made it extremely difficult tophase individual loci, understand how these arechronologically related, and assess the taphonomicorigins of individual deposits. A more formal organization of space starting in

the PPNA may have provided social and organi-zational advantages by segregating more distinctareas of space in the community and tailoringeveryday tasks to the long- term requirements ofsedentism. While beyond the scope of this paper,we suggest that the adaptation of formalized intra- community organization during the early stages ofthe transition to agriculture served as a necessaryorganizational foundation for the development ofmore complex human societies. Despite the lim-ited study of this topic, preliminary considerations(e.g., Flannery 2002; Hodder and Cessford 2004;Twiss et al. 2008) of large agricultural villages inthe Pre- Pottery Neolithic B, illustrate a long- termtrajectory of continually intensifying communityorganization from Epipaleolithic foragers toNeolithic villagers.

Conclusions

In this paper, our analyses allow us to track the ori-gins of loci from two disparate occupations at ‘Iraq ed- Dubb. Based on this evidence we argue that toolkits can be identified for each occupation of the site,and demonstrate that the spatial patterns for eachoccupation are very different. The relatively non-delineated activity areas of the Late Natufian areconsistent with the assertion that they were a rela-tively mobile population. In contrast, the PPNAoccupation shows more intensive community orga-nization with designated activity areas even foreveryday domestic tasks. Finally, we suggest thatthe complete social and economic package thatfacilitated sedentism as a long- term viable strategywas only adopted with the emergence of later Pre- Pottery Neolithic period villages. In the Pre- PotteryNeolithic A period there is clear evidence for thedevelopment of early refuse management systemsand highly delineated activity areas. We suggest that

the development of formalized site organization, inconjunction with other ecological variations andhuman societal development, were both a byprod-uct of the transition to agriculture as well as facil-itating growth and organization of Neolithiccommunities. This analysis helps us understand some of the

broader aspects of the pathway to human seden-tism. While Natufian foragers /hunter- gathererslived in a world that shared some material aspectswith later Neolithic agriculturalists, including asubstantial ground stone industry and the con-struction of substantial residential buildings, spacewithin Late Natufian settlements was organized ina similar manner to preceding and other mobilesocieties. Subsequently, something quite different,in terms of the behavioral organization of space,began to happen in the early Neolithic with thedevelopment of more formalized uses of space. InTrevor Watkins words (1990:337), there mayindeed be the “change of view from the house as ashelter, the centre of certain everyday activities, tothe house as a home, the centre of the family,” andthe place where humans began to tailor their orga-nization to the long- term requirements of seden-tism.

Note

1. Researchers debate if the Natufian should be subdi-vided into two or three subphases. Traditionally, the Natufianhas been divided into the Early Natufian (ca. 15,000–13,500cal B.P.) and the Late Natufian (ca. 13,500–11,500 cal B.P.).Alternatively, Valla (1987) and Goring- Morris and Belfer-

Cohen (1998) argue that the Natufian period should be envi-sioned as consisting of the Early Natufian (ca. 15,000–13,500cal B.P.), the Late Natufian (ca. 13,500–12,700 cal B.P.) andthe Final Natufian (ca. 12,700–11,500 cal B.P.). In our view,there are merits to both arguments. For the purposes of thispaper we use the general label of Late Natufian, but would

like to stress that in using this label, we are not discounting aproposed revision of Natufian cultural- historical framework.
