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.     

First Evidence of Collective Human Inhumation from the Cardial Neolithic (Cova Bonica,Barcelona, NE Iberian Peninsula)

Excavations at Cova Bonica (Barcelona, Spain) have revealed 98 human remains, grouped into five age clusters and corresponding to a minimum of six non-articulated individuals. The remains are clearly associated with Cardial pottery, lithic artifacts, and ornaments suggesting an Early Neolithic horizon. The radiocarbon dating of three human individuals provides a reliable attribution to this period, with a range between ca. 5470 and 5220 cal b.c., identifying it as one of the few assemblages of human remains directly dated from this period. These remains correspond to a rare collective human inhumation and join a growing body of samples from the Cardial Neolithic, which is providing some of the important sites for the study of population movement and the spread of Neolithization along the western Mediterranean coast.     

Production and subsistence strategies at El Zafrín (Chafarinas Islands,Spain): new data for the early Neolithic of North-West Africa

Until a few years ago North-West Africa was ignored in our hypothesis on the neolithization of Western Mediterranean. Moreover, the few excavations focused exclusively on the test of stratigraphies in order to obtain chronological sequences. Recently developed archaeological projects allowed the inclusion of this region in the scientific debate on the origin and evolution of its Neolithic, on the contacts with the Iberian Peninsula through the Strait of Gibraltar, as well as on the documentation of ways of live, habitation structures, and economic strategies. The open area excavation of Zafrín, in the Chafarinas Isles – an archipelago located a short distance from the North African coast – and the full analysis of its lithic industry (technology, typology and use-wear), here presented, represents a novelty on the Neolithic research in North Africa. This in turn will permit us to approach subsistence strategies and the way of life developed by the Neolithic communities of the region.
