The Neolithic period marks a fundamental break in human history, contrasting sharply with the Paleolithic societies that preceded it. In the Paleolithic, European populations were extremely dispersed: just 7,000 people inhabited the entire continent 20,000 years ago, organized into small nomadic groups of 20 to 50 individuals who followed migratory herds over vast distances.

Global warming at the end of the Ice Age radically transformed this social organization. The emergence of forests replaced migratory fauna with more sedentary forest fauna, enabling human groups to become semi-sedentary. This transformation was accompanied by a spectacular demographic boom: from an estimated European population of between 10,000 and 50,000 at the end of the Paleolithic, the Middle and Final Neolithic saw a rise to between 1 and 5 million inhabitants.

This gradual sedentarization precipitated profound social transformations. Neolithic agriculture gave rise to the modern concept of work: attachment to a specific territory meant tending to one's property, storing the fruits of one's labor and planning for future harvests. This new relationship with time—deferring present use for future benefit—revolutionized social organization.

Pottery perfectly illustrates this evolution: initially developed to store cereals and seeds, it is evidence of this new ability to anticipate future needs. Some prehistorians even argue that the Neolithic would not have been possible without these storage systems.

Private property emerged as the central institution of these new societies. While individual property had already existed in the Paleolithic (such as personal hunting spears), it took on an unprecedented territorial dimension in the Neolithic. This land appropriation led to the first archaeologically documented human conflicts, necessitating the emergence of a function dedicated to territorial security function.

Agriculture made it possible to feed larger populations while freeing some individuals from the direct necessity of food production to pursue other productive activities. This emerging specialization - farmers, potters, craftsmen, guards - laid the foundations for the division of labor and social hierarchies.

Archaeological remains bear witness to this growing stratification: burials evolved from collective to differentiated individual graves, and housing moved from architectural uniformity to constructions revealing distinct social statuses. The presence of funerary objects—ornaments, specialized tools, pottery—provides material evidence of an emerging concept of wealth and social prestige.

Archaeological analysis reveals extensive exchange networks for the time. Materials such as obsidian, green rock (dolerite, jadeite), shells, and bitumen were found hundreds of kilometers from their extraction sites. Polished green rock axes, essential for deforestation and the construction of early villages, circulated throughout Neolithic Europe.

These exchanges concern both raw materials and finished objects, revealing an appreciation of artisanal specialization. The value attributed integrates both the rarity of the material and the technical skill required to transform it.

The organization of exchanges varies according to the scale considered. Within communities, anthropologists favor the hypothesis of an economy of gift and counter-gift, with informal credit systems based on interpersonal trust. In these restricted groups, the "Dunbar number" (150 people maximum to maintain direct relationships of trust) defines a scale within which deferred exchanges without any market mechanism.

There are several types of barter:

Between different communities, the absence of bonds of personal trust favored the emergence of more formalized exchanges. Certain goods gradually acquired a special status through their ability to be demanded by foreign groups, prefiguring the first forms of proto-currency.

The Austrian school of economics interprets this evolution as the spontaneous emergence of privileged exchange goods. Shells, archaeologically attested as early as the Mesolithic, illustrate this phenomenon: found far from their geographical origin (Mediterranean shells in western France, Nordic shells on other sites), they testify to a common recognition of their exchange value.

These goods are distinguished by their ability to be demanded by others, an essential quality that prefigures the monetary function. Although they did not achieve the standardization of historical currencies, they were the first steps towards depersonalized exchange systems, a prerequisite for the development of complex societies beyond the tribal framework.

The Neolithic thus laid the foundations of the modern economy: specialization of labor, private property, accumulation of wealth, social hierarchization, and the emergence of sophisticated exchange systems that transcended the bonds of kinship and direct neighborliness.
