Regional population collapse followed initial agriculture booms in mid-Holocene Europe

Following its initial arrival in SE Europe 8,500 years ago agriculture spread throughout the continent, changing food production and consumption patterns and increasing population densities. Here we show that, in contrast to the steady population growth usually assumed, the introduction of agriculture into Europe was followed by a boom-and-bust pattern in the density of regional populations. We demonstrate that summed calibrated radiocarbon date distributions and simulation can be used to test the significance of these demographic booms and busts in the context of uncertainty in the radiocarbon date calibration curve and archaeological sampling. We report these results for Central and Northwest Europe between 8,000 and 4,000 cal. BP and investigate the relationship between these patterns and climate. However, we find no evidence to support a relationship. Our results thus suggest that the demographic patterns may have arisen from endogenous causes, although this remains speculative.

New evidence of Lateglacial cereal cultivation at Abu Hureyra on the Euphrates

Hitherto, the earliest archaeological finds of domestic cereals in southwestern Asia have involved wheats and barleys dating from the beginning of the Holocene, 11–12000 calendar years ago. New evidence from the site of Abu Hureyra suggests that systematic cultivation of cereals in fact started well before the end of the Pleistocene by at least 13000 years ago, and that rye was among the first crops. The evidence also indicates that hunter-gatherers at Abu Hureyra first started cultivating crops in response to a steep decline in wild plants that had served as staple foods for at least the preceding four centuries. The decline in these wild staples is attributable to a sudden, dry, cold, climatic reversal equivalent to the ‘Younger Dryas’ period. At Abu Hureyra, therefore, it appears that the primary trigger for the occupants to start cultivating caloric staples was climate change. It is these beginnings of cultivation in the late Pleistocene that gave rise to the integrated grain-livestock Neolithic farming systems of the early Holocene.

Millets across Eurasia: chronology and context of early records of the genera Panicum and Setaria from archaeological sites in the Old World.

We have collated and reviewed published records of the genera Panicum and Setaria (Poaceae), including the domesticated millets Panicum miliaceum L. (broomcorn millet) and Setaria italica (L.) P. Beauv. (foxtail millet) in pre-5000 cal b.c. sites across the Old World. Details of these sites, which span China, central-eastern Europe including the Caucasus, Iran, Syria and Egypt, are presented with associated calibrated radiocarbon dates. Forty-one sites have records of Panicum (P. miliaceum, P. cf. miliaceum, Panicum sp., Panicum type, P. capillare (?) and P. turgidum) and 33 of Setaria (S. italica, S. viridis, S. viridis/verticillata, Setaria sp., Setaria type). We identify problems of taphonomy, identification criteria and reporting, and inference of domesticated/wild and crop/weed status of finds. Both broomcorn and foxtail millet occur in northern China prior to 5000 cal b.c.; P. miliaceum occurs contemporaneously in Europe, but its significance is unclear. Further work is needed to resolve the above issues before the status of these taxa in this period can be fully evaluated.

Archaeobotanical evidence for the spread of farming in the eastern Mediterranean

A major topic of debate in Old World prehistory is the relative importance of population movement versus cultural diffusion in explaining the spread of agriculture into and across Europe following its inception in southwestern Asia. An important set of data that has surprisingly been largely absent from this debate is the preserved crops and associated weeds of the earliest farmers. An analysis of archaeobotanical data from 40 aceramic Neolithic sites in southwestern Asia and southeastern Europe shows that there are vegetational signatures that characterize the different geographical regions occupied by the Early Neolithic farmers. On this basis it is argued that the compositional similarities of the crop package between the Levantine core, Cyprus, and Greece are indicative of both the routes of migration of early farming groups and the early agricultural practices of Europes first farmers.

Prehistoric Environment and Settlement in the Azraq Basin: an Interim Report on the 1987 and 1988 Excavation Seasons

AbstractThe Azraq Project was begun in 1975 in order to learn more of the history of environment, settlement and subsistence in the presently arid zone of South-West Asia during the late Glacial and early Holocene—the period crucial to the beginnings of food production. In 1975 a survey was made of fifteen localitites around the Azraq Basin and the area was found to be rich in sites of late Acheulian to Neolithic date. Evidence was also found for a large Pleistocene lake at the centre of the depression (Garrard et al. 1975, 1977). In 1982 a more detailed archaeological and geomorphological survey was made of the area of the former lake and of two of its western tributary wadis–Wadis el-Jilat and Kharaneh (Garrard et al. 1985a,b). A range of Epipalaeolithic and Neolithic sites were found associated with the expansion and retreat of the last major lake. Similarly dated, as well as earlier. Upper Palaeolithic, sites were also found in the western tributary wadis, at the present steppe–desert boundary. The Up...

The Evolution of Neolithic Farming from SW Asian Origins to NW European Limits

The spread of agriculture is here examined from the perspective of changes in the composition of archaeobotantical assemblages. We apply multivariate analysis to a large database of plant assemblages from early Neolithic sites across South-West Asia and Europe and show that there are coherent and meaningful changes in their composition over time, to a large extent driven by a reduction in crop-taxa diversity. We interpret these changes as being partly caused by environmental factors, and partly caused by cultural reasons linked to the relatively rapid expansion of Linearbandkeramik (LBK) groups that inhibited diversification of crops until later in the Neolithic.

Agro-pastoralist colonization of Cyprus in the 10th millennium BP: initial assessments

Unexpectedly early evidence for the precocious spread of farming has recently emerged in Cyprus. It is argued that the transmission occurred as a result of migration related to ecosystem stress in the Levant. So strong are the connections of the colonists with the mainland that we suggest the term Cypro-Pre-Pottery Neolithic B to describe what has hitherto been a major lacuna in Cypriot prehistory. Consistent dates from key sites and the evolution of material culture indicate that this Cypro-PPNB sequence represents the hitherto elusive ancestry for the Khirokitian.

Neolithic Dispersals from the Levantine Corridor: a Mediterranean Perspective

Abstract The earliest agro-pastoralists of the Near East are generally held to have emerged in a narrow Levantine Corridor. Agricultural life initially spread from this discrete core zone in the Early Pre-Pottery Neolithic B to adjacent inland regions, only reaching the Mediterranean coast of Syria by the Late Pre-Pottery Neolithic B. Recent discoveries on Cyprus, far to the west of the core zone, prompt re-configuration of several elements of this model. They also provide evidence for characteristics of a regional variant of the PPNB and, in a broader context, fresh data for an understanding of the triggers and mechanics of precocious neolithic dispersals.

Reassessing the evidence for the cultivation of wild crops during the Younger Dryas at Tell Abu Hureyra, Syria

Abstract The episodic periods of climate change between the end of the Pleistocene and the Early Holocene had significant effects on vegetation in the Levant. The three Late Epipalaeolithic phases at Tell Abu Hureyra (c. 13·1 kya cal. BP to 12·0 kya cal. BP) span the onset of the Younger Dryas when there was a reversion to cold and dry conditions from the preceding warmer/wetter Bølling-Allerød interstadial. The deterioration of the climate is argued to have caused a recession of Mediterranean woodland from the immediate environs of the site and thus the habitats of many of the edible large-seeded annual plants became less accessible. Changes in the taxonomic composition of the archaeobotanical samples from the three Late Epipalaeolithic phases were interpreted by the original analyst as reflecting diet change in response to a reduction in resource availability, with the inception of cultivation of wild cereals and large-seeded legumes to maintain yields of these high-ranked species. In this reassessment of the data we propose an alternative model and demonstrate that the changes in plant exploitation strategies at Abu Hureyra, which coincide with the onset of the Younger Dryas, can be more parsimoniously interpreted as representing a broadening of the plant diet to compensate for a loss in availability of higher-ranked species.

The origins and spread of stock-keeping: the role of cultural and environmental influences on early Neolithic animal exploitation in Europe

It has long been recognised that the proportions of Neolithic domestic animal species—cattle, pig and sheep/goat—vary from region to region, but it has hitherto been unclear how much this variability is related to cultural practices or to environmental constraints. This study uses hundreds of faunal assemblages from across Neolithic Europe to reveal the distribution of animal use between north and south, east and west. The remarkable results present us with a geography of Neolithic animal society—from the rabbit-loving Mediterranean to the beef-eaters of the north and west. They also demonstrate that the choices made by early Neolithic herders were largely determined by their environments. Cultural links appear to have played only a minor role in the species composition of early Neolithic animal societies.
