Ecological constraints on the first prehistoric farmers in Europe

The Neolithic Revolution, which witnessed the transformation of hunter–gatherer groups into farming communities, is traditionally viewed as the event that allowed human groups to create systems of production that, in the long run, led to present-day societies. Despite the large corpus of research focused on the mechanisms and outcomes of the Neolithic transition, relatively little effort has been devoted to evaluating whether particular production-oriented adaptations could be integrated into a broad range of ecological conditions, and if specific cultural traditions differed ecologically. In order to investigate whether the differences between the adaptations and geographic distributions of three major Early Neolithic archaeological cultures are related to the exploitation of different suites of environmental conditions, we apply genetic algorithm and maximum entropy ecological niche modeling techniques to reconstruct and compare the ecological niches within which three principal Neolithic cultures (Impressed Ware, Cardial Ware, and Linearbandkeramik) spread across Europe between ca. 8000 and 7000 cal yr BP. Results show that these cultures occupied mutually exclusive suites of environmental conditions and, thus, were adapted to distinct and essentially non-overlapping ecological niches. We argue that the historical processes behind the Neolithization of Europe were influenced by environmental factors predisposing occupation of regions most suited to specific cultural adaptations.     

Founder effect, drift, and adaptive change in domestic crop use in early Neolithic Europe

We document and quantify a significant reduction in crop diversity in the early central European Neolithic using a large multi-site database of archaeobotantical remains we compiled from published Neolithic sites across southwest Asia and Europe. Two hypotheses are proposed to account for the observed changes: one which claims that the different environmental conditions of central Europe selected for a different set of crop choices and strategies than in use in southeast and Mediterranean Europe; and a null hypothesis that explains the change as a drift process associated with a small founding population that subsequently undergoes rapid expansion. Through an agent-based simulation model, we test the null hypothesis and demonstrate that the drop in diversity exceeds that predicted by a drift process. We conclude by re-evaluating the possible adaptive changes underlying crop use in early Neolithic Europe.     

Forager–farmer connections in an ‘unoccupied’ land: First contact on the western edge of LBK territory

The interaction between local foragers and incoming farmers is one of the hot topics in the study of Europe’s recent prehistory. In Central and Western Europe’s loam region, occupied by the first farmers of the Linearbandkeramik (LBK), hunter–gatherer remains are scarce and consist mostly of surface finds. Hence, the hunter–gatherer occupation and activity on the loess has never been studied in detail. This paper tackles the problem of the visibility of hunter–gatherer activity on the loess belt. An interregional comparison of microlith datasets allows identifying behavioural changes and differences in exploitation intensity. With regard to forager–farmer interaction, a mutual influence in the spatial patterning of activity or settlement is demonstrated.     

Mobility and the diversity of Early Neolithic lives: Isotopic evidence from skeletons

Isotopic analyses of tooth enamel from early Neolithic skeletons in southern Germany adds diversity to the picture of the Neolithic transition in central Europe, which has often been described as a wholesale shift in diet and technology. Over the past decade, these isotopic studies have suggested some degree of immigration from nearby indigenous groups, as well as social differences within early Neolithic communities that correlate with immigration patterns. In general, there emerges pattern a pattern of patrilocal kinship that is consistent with independent genetic evidence, and anthropologically consistent with the potential identification of Neolithic ‘nuclear families’; and finally, specialisation of subsistence activities, such as livestock herding and cultivating, probably along hereditary lines.     

Mobility or migration: a case study from the Neolithic settlement of Nieder-Mörlen (Hessen,Germany)

A combination of stable carbon and nitrogen isotope analysis of collagen and radiogenic strontium isotope analysis of tooth enamel was used to investigate diet and mobility at the early Neolithic settlement of Nieder-Mörlen in Germany. The carbon and nitrogen ratios suggest a mixed terrestrial based diet that is consistent with data previously published for early Neolithic sites in Europe. The strontium isotope data indicate a high degree of human mobility with only one individual having an isotope ratio consistent with locally derived strontium. Unusually, a group of non-local juveniles with isotope ratios typical of upland regions is also present at the settlement but there are no adult burials with such values. Whilst transhumance is considered as an explanation, it would not explain why these non-local juveniles lived foreshortened lives and other possible mechanisms are therefore discussed.
