Introduction

The Neolithic period, spanning the 9th through early 5th millennia B.C., was a time of two fundamental and far-reaching changes in the Near East: the begin­nings of settled village life and the first appearance of food production — the raising of domesticated plants and animals. Much anthropological study of early plant and animal domestication in the ancient Near East has focused on the question of origins; where, when, how, and why man first made the transition from hunting and gathering to food pro­duction. Although the problem of Neolithic origins continues to be a major research topic, it is equally important and challenging to study how these Neolithic food producing systems actually functioned once they were established:

Excavated animal bone remains from the Aceramic Neolithic site of Gritille in southeastern Turkey (Fig. 2) provide one way to investigate the ways in which animal herding or stock raising might have been prac­ticed at this early village community. This discussion will attempt to answer three questions: 1) Which domesticated animals were herded at Gritille in the 7th millennium B.C.? 2) What were the herding strategies employed? In other words, how did the Neolithic villagers of Gritille raise their animals and shape the composition of their herds in order to obtain specific types of animal products? 3) Why did the people of Gritille continue to hunt, even after they had access to do­mesticated animals and domesti­cated crops as reliable sources of food? Examination of these pro­blems provides an example of the ways in which excavated animal bone remains are used to reconstruct or understand the economic systems of prehistoric societies.

Gritille Höyük

Gritille Höyük is a small mound, 1.5 hectares in area, located in the Euphrates river valley of southeastern Turkey, in the piedmont zone of the Taurus-Zagros mountain ranges—the area generally believed to have some of the earliest evidence for plant and animal domestication in the Old World (Ucko and Dimbleby 1969; Braidwood and Braidwood 1982). Gritille’s location in this transitional zone between the Anatolian high­lands and the lowland steppe of North Syria provided a variety of resources to early herders and farm­ers. In Neolithic times, the Eastern Taurus mountains formed an open woodland zone mainly dominated by oak and pistachio trees. In the Euphrates valley, winter rainfall was sufficient to support the farming of cereals such as wheat without need of irrigation of the relatively wide and flat river terraces. Rainfall in the Gritille area also supported a variety of grasses for grazing by animals, whether wild or domestic.

From 1981 to 1984, four seasons of excavations were carried out at Gritille by an expedition under the direction of Professor Richard S. Ellis (Bryn Mawr College). This field work uncovered a 9000-year­long history of settlement at GritiIle (Ellis and Voigt 1982; Voigt 1985; Voigt and Ellis 1981). The earliest occupation level at the mound, the focus of this paper, is a 3- to 4-­meter-thick deposit of well-pre­served houses, open areas, and asso­ciated artifacts dating to the 7th millennium B.C. (Fig. 3). This period of early agriculture and animal domestication is often called the Aceramic Neolithic, because it ante­dates the introduction of pottery in this part of the Near East. This phase at Gritille is thus contempora­neous with sites such as Çayönü in eastern Turkey and Pre-Pottery Neolithic B Jericho, in the Jordan river valley (see Fig. 2).

Excavations at Aceramic Neolithic Gritille have recovered stone tools, bone implements, clay figurines, and other objects that reflect the everyday activities of this early village (see Voigt 1985). In addition, approximately 80,000 fragments of animal bone were collected from the Neolithic levels as part of the Gritille Project’s research emphasis on ancient economic systems. Pre­liminary studies of a small portion of this material (ca. 3500 fragments) have provided valuable information about the economic organization of early Neolithic village communities, specifically in relation to the three problems noted earlier.

Identification of Animal Domestication in the Archaeological Record

Determining which domesti­cated animals were present at Neolithic Gritille poses a basic but difficult problem. The first step is to identify the animals from their bones, and then determine whether these were wild or domes­ticated forms of sheep, goat, cattle, pig, or dog. Identification of many fragments is often difficult or im­possible because the animal bones recovered in excavation are fre­quently small fragments crushed under millennia of later buildings, burnt, cooked, trampled, or gnawed beyond recognition by dogs in the ancient settlement (Fig. 4).The spe­cies present at an archaeological site can be identified by comparing the excavated bone fragments with the skeletons of modern animals of known species. Analysis of this sort, using comparative faunal collections at MASCA (the Museum Applied Science Center for Archaeology) and the University of Pennsylvania Anthropology Department, revealed that sheep and goats as a group were the most common animals at Neolithic Gritille, comprising ap­proximately 80 percent all identi­fiable bone fragments examined to date. At both Gritille and the nearby contemporaneous site of Çayönü, sheep outnumbered goats by more than 2:1. Pigs were second in impor­tance, and cattle third. Deer, gazelle, hares, hedgehogs, and (apparently domesticated) dogs were also pre­sent in small numbers. Although Gritille is located on the banks of the Euphrates river, the Neolithic inhabitants of the site appear to have relied far more heavily on land mammals than on aquatic resources (e.g., fish or mussels).

After identifying what animals were present at Gritille, the next step consists of determining whether the potential food animals—sheep, goats, pigs, and cattle—from this site were wild or domesticated. Domestication can be thought of as a process of increasing human control over animals so that they are kept captive, bred, and exploited for their products, such as meat, dairy goods, hides, or wool. After a certain amount of time, controlled breeding, feeding, and selective culling of animals resulted in changes of size, shape, and behavior of the newly domesticated livestock. In short, the early effects of domes­tication can be characterized as the eventual emergence of selectively bred sheep, goats, cattle, and pigs that were smaller, more docile, and considerably less intelligent than their wild counterparts.

Three types of changes in a faunal sample provide important clues as to whether or not an animal has been domesticated:

1) Reduction in size: Early domes­ticated animals are often smaller than their wild ancestors (Fig. 5). This domestication-related size re­duction appears in some teeth and bones more clearly than in others. Thus, for example, in cattle, measure­ments of the third molar, astragalus, distal humerus, distal metacarpal, first phalanx, and third phalanx can all be used to determine whether the animal was wild or domestic. Similarly, measurements of the second and third molars of pigs can often provide good distinctions between wild and domestic swine. In attempting to determine whether an animal is wild or domesticated, ideally measurements from a large sample of bones or teeth should be used (since animals can vary con­siderably in size, even within the same population). Unfortunately, in the faunal sample analyzed so far from Neolithic Gritille, only a few of the most useful bones and teeth were preserved well enough to be measurable.

The metric evidence suggests that both wild and domestic cattle were present at Neolithic Gritille. A nearly complete third phalanx (hoof) from Gritille is 56.26 millimeters long, falling well below the 81-109 milli­meter size range for wild cattle (Hole, Flannery, and Neely 1969: 307). Similarly, a fragmentary cattle first phalanx (toe bone) from Gritille has a proximal width of 24.08 millimeters, within the expected size range for a domesticated individual (see Hole, Flannery, and Neely 1969:306, fig. 127). Measurements of other phalanges suggest that wild cattle continued to be hunted in addition to the herding of domesti­cated cattle.

Measurements of pig teeth seem to indicate that swine at Neolithic Gritille were at a very early stage of domestication (if they were domes­ticated at all). H. Stampfli’s analysis of the pig remains from Çayönü, suggested a series of tooth sizes that characterize domesticated versus wild pigs (Lawrence 1980:307). By these criteria, the five measurable second and third molars from Gritille fall just within the expected range for domesticated pigs; however, the measurements given in another study of pig domestication in the Near East (Flannery 1983:table 3) suggest that the Gritille Neolithic teeth fall within the range of the smallest wild pigs in the area. This ambiguity might be explained by suggesting that the pigs at Neolithic Gritille were in a very early stage of domestication. Clearly, we need a much larger sample of measurable teeth from Gritille in order to determine whether the pigs at this site were domesticated, transitional, or wild.

2)   Morphological Changes: The second clue to domestication is a change in the shape of certain bodyparts. For example, in one of the characteristic genetic changes associated with domestication, the shape of goat horn cores shifts from a straight “scimitar” shape to a helically twisted or “corkscrew” shape (Figs. 6, 7; Hole, Flannery, and Neely 1969:270-278).

3)   Culling Patterns: The third form of evidence for domestication is a change in the ages of the animals killed. Herds of wild sheep and goats consist of mostly adult animals, with a relatively small percentage of young lambs or kids (due to the extremely high natural mortality rate from disease, predation, and adverse weather conditions in the wild). Since hunters would in any case want to bring home as much meat as possible, it would make sense for them to kill mostly full-grown adults. For these two reasons, if an archae­ologist finds large numbers of adult sheep and goat remains, it is likely that these animals were hunted (see, e.g., Hesse 1982).

If the sheep and goats were domesticated, we would expect to find mostly young animals. One major reason for this is that the Neolithic herders would have been selectively killing off or culling the young male sheep and goats so that they would not compete for grazing and fodder with the more productive and valuable females. In addition, one would expect natural deaths from disease to affect young animals more severely than adults. In short, if a village had domesticated an­imals, the effects of natural mortality combined with the deliberate killing-off of young males would result in a situation where the bones of young animals are very common in archae­ological deposits at that site.

Thus, the presence of many adult animals suggests the hunting of wild sheep and goats, while the predom­inance of young animals (two years old or less) suggests the herding of domesticated animals. The age at which an animal was killed can be determined by examining either the fusion of bones (Fig. 8) or the eruption and wear of teeth (Fig. 9). The ages at which different bones fuse are known from studies of modern animals. Similarly, teeth erupt at specific ages and wear down at a more or less consistent rate. As a result, by examining the mandible (jaw bone) of a sheep or goat from Neolithic Gritille, we can give a relatively precise determin­ation of the age at which it was killed. A study of the sheep and goat mandibles from Gritille showed that more than 60 percent were young animals killed before they reached an age of two years. This strongly suggests that most of the sheep and goats of Gritille were domesticated in Aceramic Neolithic times.

In short, the three types of ev­idence for domestication—size, mor­phological changes, and changes in age structure—give good evidence that sheep, goat, cattle, and possibly pigs were domesticated at Gritille in the late 7th millennium B.C. But the evidence also shows that there was at least some hunting of deer, gazelle, wild cattle, and possibly wild goat at this time.

Herding Strategies

Given that domesticated sheep, goats, cattle, and (possibly) pigs were present at Gritille, we can now look at the second question posed at the begin­ning of this discussion: How did the Neolithic villagers of Gritille raise their animals and shape the compo­sition of their herds in order to obtain specific types of animal products? In other words, what type of herding strategies did they employ?

Sheep and goats can yield a variety of different products, such as dairy goods, meat, or fiber (wool or goat hair). The ideal herd composition differs for each of these production goals. For this reason, depending on whether the herder wants to empha­size dairy, meat, or fiber production, he would shape the age and sex composition of his flock in a different way. Graphs that plot the number of animals culled at each age are called survivorship curves. The different culling patterns for each production goal will generate dis­tinctive survivorship curves for dairy herds, wool herds, or herds raised mainly as a source of meat (see Fig. 10).

For example, with dairy pro­duction the males would be culled at a very early age (up to 6 months old), since they have no milk pro­ducing potential and compete for grazing with the females. By con­trast, in meat production males would be culled later in life (at about 18 to 24 months old) when they begin to reach optimum meat weight. In wool production, males would be castrated and retained in the herd, resulting in a completely different survivorship curve (see Payne, 1973).

By examining the bone and teeth from an archaeological site, we can determine the ages at death of the animals and reconstruct a survivor­ship curve for that herd. By com­paring the archaeological survivor­ship curve with the survivorship curves for known products, we can make an educated guess at whether the ancient villagers were raising their animals to provide curds, kebab, or kilims (woolen textiles). Figure 11 shows the reconstructed survivorship curve for Neolithic Gritille. The ages of the sheep and goats fit very closely with the kind of culling or kill-off pattern we would expect if these animals were being raised mainly for their meat (Fig. 12). As yet, the analyzed sample of cattle remains from Neo­lithic Gritille is still too small to allow for any reconstruction of the herding strategies followed.

Hunting by Herders

Having examined domesti­cated herds, we can now turn to the third question: Why did the people of Gritille continue to hunt, even after they had domesticated animals and crops as reliable sources of food? In trying to answer this question, it helps to look at two very different sets of schedules: 1) the seasonal cycle of agriculture and herding, and 2) the seasonal cycle by which wild animals such as deer or mountain goats migrate from summer to winter grazing areas. Briefly, these schedules suggest that the villagers hunted in the winter and relied much more on domesticated crops and animals for the rest of the year (Fig. 13).

The production of domesticated crops and animals in the Near East follows a consistent seasonal round. In southeastern Turkey, cereals are planted in October or early No­vember, and harvested in June or July. In the herding cycle, sheep and goats are born in the winter, usually in the period from January to March. For both the agricultural and herding cycles, winter is the time of greatest uncertainty. The villagers do not know how the crops will survive, or how long they will have to live off their stocks of stored grain. For the herds, the winter birthing season is a particularly risky period because it is a time when the newly born Iambs and kids are particularly susceptible to disease and relatively harsh weather conditions.

In short, winter is a time when farmers and herders are extremely reluctant to consume their stored crops or animals because they do not yet know how well the next harvest will turn out or how well their herds will survive the winter birthing season. The seasonal cycle of wild animals, however, would have provided a valuable added resource to the Neolithic villagers of Gritille at just the time when it could provide the greatest bene­fit—in winter. Animals such as red deer, fallow deer, wild goats, and wild sheep have a fairly predictable seasonal migration in which they spend summer in the uplands and winter in the lowlands (Fig. 14).

Gritille is located along the Eu­phrates in the largely snow-free flood plain, while the neighboring mountains and plateau are snow-covered in winter (Fig. 15). In a situation like this, deer, wild goats, and probably wild cattle, as well, would have come out of the hills into the Euphrates river valley as a prime winter grazing area. In other words, every winter these wild animals would have been coming straight towards Gritille at precisely the time when the villagers were most reluctant to consume their domesticated animals or stored crops. If this suggestion is correct, then hunting emerges as an impor­tant part of the Neolithic economy — it would have provided an easily available and fairly reliable source of food that could be used each winter until the villagers had a better idea of how well their crops and herds would survive and produce that year.

Conclusion

The animal bone remains from Gritille suggest that the Neo­lithic villagers there herded domesticated sheep, goat, cattle, and (possibly domesticated) pigs as a source of meat for the spring, summer, and autumn. In winter, however, they may well have de­pended much more on hunting the deer, wild cattle, and wild sheep or goats that migrated down from the highlands into the Euphrates river valley.

When we consider the Neolithic economy at Gritille as a carefully scheduled combination of cropping, herding, and hunting, the picture that emerges depicts a seasonal cycle of alternating bounty and scarcity, conservatism and willingness to consume. In this view, the Aceramic Neolithic villagers of Gritille were people who knew their environment and exploited it in a variety of ways with great ingenuity.
