From around 2750 to 2500 bc, Bell Beaker pottery became widespread across western and central Europe, before it disappeared between 2200 and 1800 bc. The forces that propelled its expansion are a matter of long-standing debate, and there is support for both cultural diffusion and migration having a role in this process. Here we present genome-wide data from 400 Neolithic, Copper Age and Bronze Age Europeans, including 226 individuals associated with Beaker-complex artefacts. We detected limited genetic affinity between Beaker-complex-associated individuals from Iberia and central Europe, and thus exclude migration as an important mechanism of spread between these two regions. However, migration had a key role in the further dissemination of the Beaker complex. We document this phenomenon most clearly in Britain, where the spread of the Beaker complex introduced high levels of steppe-related ancestry and was associated with the replacement of approximately 90% of Britain’s gene pool within a few hundred years, continuing the east-to-west expansion that had brought steppe-related ancestry into central and northern Europe over the previous centuries.

Abstract
From around 2750 to 2500 BC, Bell Beaker pottery became widespread across western and central Europe, before it disappeared between 2200 and 1800 BC. The forces that propelled its expansion are a matter of long-standing debate, and there is support for both cultural diffusion and migration having a role in this process. Here we present genome-wide data from 400 Neolithic, Copper Age and Bronze Age Europeans, including 226 individuals associated with Beaker-complex artefacts. We detected limited genetic affinity between Beaker-complex-associated individuals from Iberia and central Europe, and thus exclude migration as an important mechanism of spread between these two regions. However, migration had a key role in the further dissemination of the Beaker complex. We document this phenomenon most clearly in Britain, where the spread of the Beaker complex introduced high levels of steppe-related ancestry and was associated with the replacement of approximately 90% of Britain’s gene pool within a few hundred years, continuing the east-to-west expansion that had brought steppe-related ancestry into central and northern Europe over the previous centuries.

Attempts to correlate macro-scale climate dynamics with anomalies in local and regional archaeological data sets should account for differences in geographic scale and effect size. Using the modern analogue technique, this paper reconstructs temperature, precipitation, and growing degree-day trends in Ukraine, Moldova, and Romania from a set of 20 pollen cores in order to explicate the regional impact of the 6.0–5.0 ka BP rapid climate change interval observed in the GISP2 K+ glacio-chemical sequence. Results are compared against a model of regional demographic development covering the time span of 6000–3000 BCE. This study indicates that, while macro-scale trends are discernible in Eastern Europe, climatic instability during the fourth millennium BCE was regionally variable and resultant demographic responses were highly targeted and heterogeneous in nature. A period of cooling ca. 3825–3650 cal BCE resulted in the fracturing of Eneolithic complexes in Romania and generally spurred adaptation to more mobile systems of settlement and subsistence. However, a contemporaneous alternative response involved large-scale migrations to peripheral regions, including the establishment of the Tripolye giant-settlements in Central Ukraine. The methods used illustrate the need for obtaining more proximate confirmation when applying large-scale climate processes to explanations of local and regional archaeological contexts.

While numerous studies have attempted to reconcile the relative sequence of Late Tripolye sites with 14C data, results have generally conformed to the general, monolithic periodization of the Cucuteni-Tripolye cultural complex. When viewed as a multi-linear process occurring on the level of numerous interrelated regions, the development
of local groups assigned to the periods CI, CI-II and CII can be shown to have a high degree of spatiotemporal variability and overlap. In this article we explore the synchronicity of interactions between groups
assigned to different typo-chronological periods and propose a revised hybrid chronology for Late Tripolye development that considers both relative and absolute chronological indicators.

Наведено результати декількох скалярних аналізів із 1800-х років динаміки розвитку населення Кукутень-Трипілля з особливим акцентом на швидкій міграції західнотрипільського населення, починаючи з 4150 calBC, що призвели до розвитку поселень-гігантів у Центральній Україні. Виконано моделювання динаміки розвитку населення у великих масштабах, статистичний аналіз для демонстрації значної кореляції між формуванням поселень-гігантів і вірогідністю одночасних періодів раптових глобальних змін клімату. Завдяки використанню точних даних щодо клімату це дослідження доповнює та розширює теорії про вплив клімату на популяційну динаміку Кукутень-Трипільського населення та формування великих поселень.

This paper presents the results of a multi-scalar analysis of 1800 years of Cucuteni-Tripolye population dynamics, with particular emphasis on the rapid Western Tripolye migrations beginning c. 4150 calBC that led to the development of the giant-settlement phenomenon in Central Ukraine. In addition to macro-scale population modeling, statistical analysis is performed to demonstrate a significant correlation between giant-settlement formation and proxies for a concurrent period of sudden, global climate change. Due to the highly complimentary nature of the climatic record and available archaeological data (empirical and modeled), it is proposed that this climatic variability had wide-ranging effects on Cucuteni-Tripolye population dynamics, subsistence, and settlement organization.

The giant-settlement of Talianki, situated in the Southern Bug-Dnieper interfluve in Central Ukraine, is the largest known settlement of not only the Western Tripolye culture, but also the entire European Neolithic and Eneolthic. As with the rest of the giant-settlements belonging to this culture, Talianki's unusually large size and short habitational period makes understanding its purpose and functioning a confounding and unique archaeological problem. While Talianki and the other settlements of its category are poorly documented in Western archaeological discourse, there is lively discussion of these topics in the Ukrainian archaeological community. The goal of this work is twofold: firstly, to expand discussion of the Tripolye culture outside of Ukraine; and secondly, to introduce research regarding the modeled functioning of an Eneolithic economy in the context of a very large settlement existing in a single-site context. A review of literature, from Ukraine and elsewhere, relevant to the modeling of ancient agrarian systems is presented, as well as recent research into the spatial and demographic character of the settlement. The purpose of this is to assess several previously-held assumptions regarding the functioning of the giant-settlements, which tend 1) to be rooted in notions of environmental determinism; and 2) to assign a degree of social and political complexity that is not perceived in the archaeological materials (due to their assumed incapability of self- sufficiency). This study, supported by mathematical and spatial modeling of settlement functioning, concludes that the giant-settlements of the Southern Bug-Dnieper interfluve would have been economically viable and self-sustaining in a variety of states, both more and less optimized. This research has value not only in modeling the functioning of a single site, but also in understanding the full limits and potential of European Neolithic and Eneolithic subsistence systems.

Archaeologists seeking to understand the economic landscape of prehistoric farming societies often make use of theoretical models such as site catchment analysis to make inferences regarding agricultural production. Such exercises arenecessarily deterministic in nature and the quality of their results fluctuates wildly depending on the quality and amount of inputs involved. The Eneolithic Tripol’ye giant-settlements of central Ukraine present a special problem for landscape studies due to the paucity of material evidence available beyond the architecture and layout of the settlements themselves.This paper seeks to re-analyze published material on the Tomashevskaya local group of the Western-Tripolian Culture, particularly relating to the largest of the giant-settlements, Tal’yanki. It is proposed that through a multi-disciplinaryapproach combining archaeology with agricultural science, a more coherent picture of subsistence behaviors and social organization can be formed.

На протяжении многих лет площадь трипольского поселения-гиганта у с. Тальянки обычнооценивалась в 450 га. Тем не менее, это значение является геометрически ложным, чтопоказывает пространственный анализ поселения. Полученная нами площадь памятника,около 335 га, достаточно близка к недавним результатам А.В. Дяченко. Следует отметить,что такое сходство оценок, скорее, случайно, и результаты были получены по разным методикам. Надеемся, что предложенные здесь данные станут полезными для дальнейшегопространственного анализа поселения-гиганта.

The conventional estimated area of the Tripolian giant-settlement of Tal'yanki, 450 ha, has for many years been a part of the Tripolian canon. However, this value can be shown to be geometrically false when tested against spatial analysis of the settlement. New estimates were generated through close study of the geomagnetic plan of Tal'yanki and computerized planimeter measurement. The received values, which can be approximated to 335 ha, are in close agreement with the recent results of A.V. Dyachenko. It should be noted, however, that this similarity is largely coincidental, with results achieved through differing methods. It is hoped that the data outlined in this article is helpful for the continued development of spatial analysis at the giant-settlements.
