The Beaker phenomenon and the genomic transformation of northwest Europe

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

The symbolic meaning of cattle and sheep/goat in the Bronze Age: Faunal inclusions in funerary contexts of South-Western Iberia

The inclusion of faunal remains in funerary practices is widely documented in Iberian prehistory. For the late prehistory (Neolithic to Bronze Age), there is relatively more data than in earlier periods, with limb segments being very common, and complete animals are rarer. In Bronze Age contexts from South-Western Iberia, a high percentage of human burials in subterranean chambers (hypogea) are associated with limb bones of cattle (Bos taurus) and sheep/goats (Ovis/Capra), along with other grave goods. Traditionally, this practice is interpreted as the result of rituals of commensality. In this paper, we present a different perspective. Besides commensality, we show that the inclusion of the same species and the same anatomical parts is a highly standardised behaviour. Beyond the tight connection between humans and animals, this pattern also points to a strong symbolism of these domestic species and to symbolic meaning of the anatomical parts themselves.info:eu-repo/semantics/publishedVersio

The maternal genetic make-up of the Iberian Peninsula between the Neolithic and the Early Bronze Age

Abstract Agriculture first reached the Iberian Peninsula around 5700 BCE. However, little is known about the genetic structure and changes of prehistoric populations in different geographic areas of Iberia. In our study, we focus on the maternal genetic makeup of the Neolithic (~ 5500–3000 BCE), Chalcolithic (~ 3000–2200 BCE) and Early Bronze Age (~ 2200–1500 BCE). We report ancient mitochondrial DNA results of 213 individuals (151 HVS-I sequences) from the northeast, central, southeast and southwest regions and thus on the largest archaeogenetic dataset from the Peninsula to date. Similar to other parts of Europe, we observe a discontinuity between hunter-gatherers and the first farmers of the Neolithic. During the subsequent periods, we detect regional continuity of Early Neolithic lineages across Iberia, however the genetic contribution of hunter-gatherers is generally higher than in other parts of Europe and varies regionally. In contrast to ancient DNA findings from Central Europe, we do not observe a major turnover in the mtDNA record of the Iberian Late Chalcolithic and Early Bronze Age, suggesting that the population history of the Iberian Peninsula is distinct in character
