The Neolithic Revolution was the transition from hunting and gathering toward settled life, farming, and herding, but its significance lies in more than a change in food production. The evidence presented here challenges the view that favorable geography and useful wild species alone caused the transition: among the Natufians, settlement, hierarchy, and institutional innovation appear to have come before farming. Against the backdrop of a warming world, societies’ differing arrangements shaped which opportunities they could seize and how the resulting gains and power were distributed.

Climate and the Opportunity for Change

The climatic background was the Long Summer. Around 15,000 BC, as the Ice Age ended, global temperatures rose; Greenland ice cores suggest increases of as much as fifteen degrees Celsius over a short period. Human populations grew as animal populations expanded and wild foods became more available. Around 14,000 BC, this process reversed during the Younger Dryas cooling, before temperatures rose again after 9600 BC—by seven degrees Celsius in less than a decade—and remained high. The sustained warming created a critical juncture for human societies, but it did not dictate a single response.

Farming and herding differed from hunting and gathering because they involved domesticating plants and animals: people intervened in other species’ life cycles, gradually changing them to be more useful. Maize illustrates the process. People gathered teosinte, a wild ancestor with cobs only a few centimeters long, then selected plants with larger ears and ears that stayed on the stalk rather than breaking away. Over time, this selection produced modern maize, yielding more nourishment from the same land. Such changes expanded food production, but the capacity to benefit from them depended on social arrangements as well as biological possibility.

Natufian Settlement Before Farming

The earliest evidence of farming, herding, and domestication comes from the Middle East, especially the Hilly Flanks, a region extending from the south of modern Israel through Palestine and Syria into southeastern Turkey, northern Iraq, and western Iran. Around 9500 BC, domestic emmer and two-row barley were found at Jericho, on the west bank of the Jordan River; emmer, peas, and lentils were also found at Tell Aswad in Syria. Both sites were associated with Natufian culture and supported large villages. Jericho may already have had a population of about five hundred.

The Natufians’ significance, however, is not simply that they lived among useful wild species. Genetic and archaeological research indicates that wild ancestors of domesticated plants and animals were distributed across vast areas, in some cases millions of square kilometers. The Hilly Flanks were rich in potential domesticates, but not uniquely so; many other peoples lived among such species without domesticating them. The book’s explanation turns instead to settlement: Natufian communities were sedentary before they began domesticating plants or animals.

Evidence from gazelle teeth supports year-round residence. The cementum in a tooth forms seasonal layers of different colors, allowing researchers to infer whether an animal was killed in summer or winter. At Natufian sites, gazelles were killed in all seasons, consistent with people residing there throughout the year. Abu Hureyra, on the Euphrates, offers an unusually well-documented sequence. Its settlement probably began around 9500 BC, and its inhabitants continued hunting and gathering for about five hundred years before switching to agriculture. Before farming, its population is estimated at between one hundred and three hundred.

Settled life offered practical advantages while bringing new demands. Moving from place to place made it difficult to store food for lean times, and heavy grinding stones and sickles were cumbersome to carry; even mobile hunter-gatherers sometimes stored food in particular locations such as caves. A dependable food store could therefore help make residence in one place attractive. But settlement also made departure a less available way of resolving disputes: people had buildings and possessions they could not easily take with them. Communities needed rules governing access to nearby land, trees, and fishing grounds, as well as institutions able to make and enforce those rules.

Institutions, Hierarchy, and the Farming Transition

The archaeological record suggests that Natufian communities had already developed hierarchy and inequality before the transition to farming. Some graves contained substantial quantities of obsidian and dentalium shells brought from the Mediterranean coast near Mount Carmel, alongside ornaments such as necklaces, garters, and bracelets made from shells, canine teeth, and deer phalanges. Other people were buried without such objects. Because shells and obsidian were traded, control over exchange may have helped concentrate power and resources, although the objects themselves provide evidence of differences in burial wealth rather than a complete account of how authority operated.

At Ain Mallaha, north of the Sea of Galilee, about fifty round huts and numerous storage pits stood near a large, intensively plastered building beside a cleared central area. The building was almost certainly a chief’s house, in the interpretation offered by the evidence. Some graves were more elaborate than others, and the site also showed signs of a skull cult, possibly connected to ancestor worship; such cults appear at other Natufian sites, particularly Jericho. Taken together, the material remains suggest societies with political hierarchies, long-distance exchange, emerging religious practices, and institutions that governed the inheritance of elite status.

This reading reverses a familiar causal sequence. A traditional geography-based explanation, associated with Jared Diamond’s argument, holds that an abundance of easily domesticated species made farming attractive, prompting settlement; hierarchy, religion, and more complex institutions then followed. The Natufian evidence points instead to institutional change well before agriculture. The text proposes that political elites may have helped enforce order, establish property rules, and organize settled communities, while also benefiting from the resources and authority such arrangements concentrated. This political breakthrough is presented as a plausible interpretation, not as a directly observed prehistoric decision.

Nor did settlement automatically produce agriculture. Natufian communities could live in one place while continuing to hunt and gather, and the more abundant wild foods of the Long Summer may have made that way of life satisfactory. Technological improvements, too, did not necessarily increase production: the example of the steel axe among the Yir Yoront of Australia shows an innovation making subsistence easier without creating an incentive to produce more. The shift to cultivation therefore cannot be treated as an inevitable consequence of either a new technology or settled life.

Growth, Divergence, and the Limits of the Evidence

Where farming did take hold, it increased agricultural productivity and supported population growth. At Jericho and Abu Hureyra, early farming villages were much larger than their pre-farming predecessors; more generally, village populations grew by between two and six times with the transition. Farming also accompanied greater occupational specialization and faster technological progress, and probably more complex, less egalitarian political institutions. These outcomes followed not simply from the presence of plant and animal species, but from the social and political innovations that allowed sedentary life and agriculture to emerge.

The Long Summer and the availability of crops and animals made new developments possible without determining exactly where or when they would occur. Small differences in institutions influenced how communities responded to the climatic opening. Some societies, including the Natufians, developed elements of centralization and hierarchy; political elites could benefit from the new abundance and from the consolidation of authority. Other societies with somewhat different arrangements did not centralize in the same way and lagged in the emergence of settled, agricultural, and more complex societies. The argument is about contingent divergence, not a universal timetable or an inevitable progression.

Agriculture subsequently spread into Europe from the Middle East beginning around 6500 BC, mainly through the migration of farmers. As institutions developed along different paths, regions diverged further; the account contrasts Europe’s trajectory with that of parts of Africa, where initial institutions differed and developments set in motion by the Long Summer occurred later and in another form. Early innovation did not guarantee lasting prosperity for its place of origin, either. The Natufians’ institutional changes may have underpinned the Neolithic transition, but they did not ensure the later prosperity of modern Israel, Palestine, or Syria. In this interpretation, early expansion occurred under extractive institutions and did not by itself create a self-sustaining path to broad prosperity.

A Critical Juncture, Not a Predetermined Revolution

The Neolithic Revolution thus serves as a case of a critical juncture: a major disruption—in this instance, climatic warming—interacting with inherited institutional differences. Such junctures can redirect development, but their effects depend on how societies are organized and who can shape the response. The same opening may enable new forms of settlement and production while also strengthening elite power and extraction. The material traces of the Natufian villages make that institutional question visible: storage pits, differentiated graves, traded ornaments, and a prominent central building record more than subsistence. They offer clues to the political arrangements that preceded farming and help explain why a warmer, more abundant world produced different social outcomes rather than one uniform path.
