The formation of Neolithic village societies involved the reorganization of social structures at the levels of the family, household, and broader communities, as well as the establishment of relationships with external groups. These transformations are difficult to discern solely from archaeological evidence. However, the general picture that emerges is one of groups composed of several nuclear families, maintaining cohesion and coexistence through various practical or symbolic means. Elements of social distinction, such as differences in wealth or gender, appear to have been limited, and instances of violence were not widespread.
Health and living conditions The adoption of the Neolithic lifestyle is generally associated with a decline in human health and stature, a trend observed in various regions through bioarchaeological studies. This deterioration is attributed to increased exposure to stress, a less diverse and lower-quality diet, the rise of infectious diseases resulting from population density and close contact with domestic animals and rodents, and the heightened risk of food shortages due to failed harvests. This would coincide with the introduction of agriculture, and perhaps also with population growth leading to a reduction in per capita resources. Inflammatory diseases also appear to have been less common among mobile hunter-gatherers. By contrast, from the middle PPNB onwards, the situation seems to have improved, no doubt due to the stabilization of the agro-pastoral system: with agriculture under control and the transition to animal husbandry completed (with the introduction of milk in particular), people were better nourished and more resilient. Average height increased and hypoplasia became less marked, but tooth wear remained high, cavities became more common, and tooth loss more frequent. In the long term, there is no significant difference between the Natoufian and Neolithic periods in terms of trauma and pathologies such as arthritis. The Neolithic lifestyle introduced differences between the sexes: men from Natoufian hunter-gatherer groups seem to have died younger than women, due to risks associated with hunting, since this activity was reserved for them; on the other hand, Neolithic men seem to have lived longer because this risk disappeared, while women's life expectancy seems to have decreased due to greater fertility, which increased the risks associated with pregnancy and childbirth. One analysis puts life expectancy at 24.6 years in the Natoufian and 25.5 years in the Neolithic; the average age of death is 31.2 and 32.1 years respectively. Stress indices, on the other hand, seem to be more pronounced in the Final PPNB/PPNC, a period of difficult subsistence and infectious diseases. It is generally believed that the domestication of animals and the resulting proximity between humans and animals led to the emergence of zoonoses, diseases transmitted from animals to humans and vice versa. However, potential evidence of this phenomenon is very limited. A few skeletons from sites in the northern Levant (Dja'de, Tell Aswad), the earliest dated to around 8500 BC, provide the earliest known evidence of tuberculosis in humans. Tuberculosis is a disease of bovine origin, and this is the period during which the domestication of this animal is supposed to have begun or to be in progress. The coincidence is therefore striking, but the possibility of an earlier presence of this disease in humans cannot be ruled out. The Late Neolithic populations of the Levant bear witness to the continuing adjustment to the Neolithic way of life: average life expectancy is around 30, deaths are more numerous between the ages of 30 and 50, and more women are over 40.
Population growth Population growth occurred during the Neolithic process, with consequences for social and economic development when demographic thresholds were crossed. However, there is disagreement regarding the starting point: as early as the Natoufian period, during the Pre-Pottery Neolithic A (PPNA), or during the Pre-Pottery Neolithic B (PPNB). In general, it is believed, based on ethnographic observations, that a sedentary lifestyle is potentially conducive to increased fertility. Compared to a mobile lifestyle, the risk of miscarriage is lower in sedentary populations, and the duration of breastfeeding is shorter, which in turn reduces the interval between conceptions duration of breast-feeding is shorter, which in turn reduces the interval between conceptions. The "Neolithic demographic transition" model, now referred to as the "agricultural demographic transition" (J.-P. Bocquet-Appel), proposes that population growth followed the adoption of a sedentary agricultural lifestyle, due to the additional caloric intake it provided. This, combined with a reduction in female energy expenditure resulting from the end of a mobile lifestyle, would have led to increased fertility while mortality remained constant, at least initially. In a second phase, mortality—particularly that of children—increased due to higher housing density, which created less healthy conditions conducive to the spread of disease, and also led to earlier weaning. Eventually, this stabilized as population density decreased. In this model, population growth is both a cause and a consequence of the initial systemic change brought about by the emergence of agriculture. Without questioning the idea of population growth, evidence for higher settlement density remains largely confined to the southern Levant, particularly during the PPNA, when the concentration of sites is relatively high. This pattern is not observed in the northern Levant, where settlements are more widely spaced, either at the beginning of the domestication process in this region Here, residences are often continuously inhabited by the same family, supporting the concept of a "house society" as defined by Claude Lévi-Strauss, where the house serves as a focal point of family organization and heritage. This may explain the symbolic expressions found in such houses, including paintings and ritual furniture. The mobility of groups and their tendency to fragment may also have helped limit the consolidation of central authority and contributed to the maintenance of an egalitarian social structure. Trends in the Ceramic Neolithic suggest that community organization and social interaction entered a new phase. This is reflected in the emergence of collective storage facilities, sealing practices indicating increased control over the distribution of goods, more extensive inter-community exchange, and the appearance of clearer "regional styles" in material culture. However, these styles should not necessarily be interpreted as evidence of ethnic groups or clans. As discussed above, burials and material culture do not provide strong evidence for social differentiation, though some indications exist. In the Early Natoufian, for example, this is seen in funerary goods, such as necklaces made of shell dentals found with approximately 8% of individuals, as well as in potential communal buildings at Mallaha and large mortars carved into bedrock, possibly for use in communal feasting rituals. For the Pre-Ceramic Neolithic, D. Pryce and O. Bar-Yosef argue that the "cult of skulls" was primarily reserved for a limited elite, reflecting a social hierarchy. They reject the idea that mortuary practices aimed at social homogenization, pointing instead to the occasional presence of prestige goods—such as obsidian—in select burials as evidence of higher status.[3] More elaborate tombs, such as those at Ba'ja, do exist, though they remain isolated cases. Even if the presence of an elite overseeing collective endeavors is acknowledged, the application of the term "chieftaincy" to this period is generally contested. The Ceramic Neolithic appears to continue this trajectory of increasing complexity. Nevertheless, a study of the Halaf culture suggests that social stratification remained limited. Housing showed little differentiation, the society was largely semi-sedentary, domestic architecture dominated, burial practices revealed minimal social distinction, and craft production was embedded within domestic settings. This society is generally considered egalitarian, although the presence of chiefs and more defined social divisions has also been proposed. Clearer indications of emerging complex societies, approaching chieftaincy, are most visible in the Mesopotamian region, particularly in the Samarra culture and its continuation in the Ubaid culture of the Chalcolithic period. Historically, two opposing interpretations of gender relations during the Neolithic have been proposed. One presents an optimistic view, portraying the period as one of harmonious coexistence in which women were valued for their maternal and nurturing roles. The other adopts a more pessimistic stance, suggesting that the advent of sedentism and the agricultural economy led to a deterioration in the status of women, due to a stronger division between public and private spheres, relegating women to domestic roles, assigning them more arduous tasks, and reinforcing social inequalities between the sexes. However, archaeological studies increasingly discourage the generalization of such evolutionary models, instead revealing varied situations across different regions. Research in this area is more advanced in the southern and northern Levant than elsewhere. Nonetheless, there is no definitive evidence that women were exclusively involved in domestic work in Neolithic societies of the Near East. Health studies in the southern Levant suggest that women in the Natoufian period lived longer than their Neolithic successors. This may be linked to increased fertility associated with sedentarization and the beginnings of agriculture, as inferred from ethnographic comparisons. For men, the opposite trend is observed, likely reflecting the lower risks associated with the sedentary farming lifestyle compared to that of mobile hunters. No significant differences are observed in trauma between the sexes. Voluptuous female figurines, rather than representing a goddess cult, are increasingly seen as reflecting a male gaze focused on the female body and sexuality. It has been suggested that archaeological interpretation itself may have contributed to a "pacified" image of the Near Eastern Neolithic, as the same clues can support different conclusions. For example, the notion that the organization of Anatolian sites such as Aşıklı Höyük, Çatal Höyük, and Hacilar had a defensive purpose has been contested. Defensive structures may have served other functions, such as protection from flooding—as proposed by O. Bar-Yosef in the case of the PPNA wall at Jericho,—or may have acted as symbolic boundaries or means of controlling movement.
Diffusion of the Neolithic way of life The Near Eastern Neolithic, originating from various focal points—primarily the northern and southern Levant, and southeastern Anatolia—spread rapidly to neighboring regions. By the Pre-Pottery Neolithic B (PPNB), the Neolithic lifestyle had reached from Anatolia to the central Zagros. This expansion continued in multiple directions: eastward across the Iranian plateau, then into Central Asia and the Indian subcontinent; northward into the Caucasus; westward into western Anatolia and Europe; and southward into Arabia and Egypt. This diffusion can be traced by the presence of key Neolithic elements, particularly the cultivation of wheat and barley and the domestication of goats and cattle, whose wild ancestors and early domestication traces are found exclusively in the Near East. There are various interpretations regarding the mechanisms and reasons behind this diffusion. Genetic studies conducted in the mid-2010s offer some insights into the spread of the Neolithic lifestyle. These studies suggest that the movement of Neolithic populations across the Near East involved migration. Populations from the Southern Levant, Central Anatolia, and the Zagros, which were genetically distinct from local hunter-gatherer groups, dispersed in several directions. Over time, these populations intermingled to such an extent that by the Chalcolithic and Bronze Ages, individuals with genetic markers from multiple regions could be identified. Specifically, Southern Levantine populations spread to East Africa, Central Anatolian populations moved into Europe, and Zagros populations expanded into
Central Asia and
South Asia. Cyprus presents an atypical case, as the island appears to have been uninhabited during the Epipaleolithic. While it was visited by mainland populations during the PPNA, the island's settlement occurred only later, during the PPNB, around 8500 BCE. These settlers likely came from the northern Levant, bringing with them aspects of the Neolithic "package," though it was still in an unfinished state. The lithic industry, art styles, and practices such as ritual skull removal were similar to those of the mainland, though the domesticated plants and animals, including cats, were not yet fully domesticated. The presence of fallow deer also suggests that some animals were introduced to Cyprus in a controlled, semi-domesticated state, with full domestication occurring later. This has led to debate about whether these animals were partially domesticated or introduced at different stages. The reasons behind these Neolithic expansions are often attributed to a combination of climatic factors and demographic pressures. Neolithic groups, believed to have had higher population growth and greater demographic dynamism, may have been compelled to move into non-Neolithic border regions where there was more available land. J. Cauvin proposes that this movement was also driven by a cultural impetus—a form of "messianism" on the part of the settlers, who were potentially seen as more advanced by surrounding hunter-gatherer groups. The Neolithic settlers brought domesticated animals, plants, ceramics, and other technologies, which could have been perceived as superior by those they encountered, even if agriculture was not necessarily more efficient than gathering in sustaining human populations. == See also ==
