    • Archaeological evidence indicates that pig domestication had begun by similar to 10,500 y before the present ( BP) in the Near East, and mitochondrial DNA ( mtDNA) suggests that pigs arrived in Europe alongside farmers similar to 8,500 y BP. A few thousand years after the introduction of Near Eastern pigs into Europe, however, their characteristic mtDNA signature disappeared and was replaced by haplotypes associated with European wild boars. This turnover could be accounted for by substantial gene flow from local European wild boars, although it is also possible that European wild boars were domesticated independently without any genetic contribution from the Near East. To test these hypotheses, we obtained mtDNA sequences from 2,099 modern and ancient pig samples and 63 nuclear ancient genomes from Near Eastern and European pigs. Our analyses revealed that European domestic pigs dating from 7,100 to 6,000 y BP possessed both Near Eastern and European nuclear ancestry, while later pigs possessed no more than 4% Near Eastern ancestry, indicating that gene flow from European wild boars resulted in a near-complete disappearance of Near East ancestry. In addition, we demonstrate that a variant at a locus encoding black coat color likely originated in the Near East and persisted in European pigs. Altogether, our results indicate that while pigs were not independently domesticated in Europe, the vast majority of human-mediated selection over the past 5,000 y focused on the genomic fraction derived from the European wild boars, and not on the fraction that was selected by early Neolithic farmers over the first 2,500 y of the domestication process.

  • Food supply and disposal of food remains at Late Bronze and Early Iron Age Ada Tepe : bioarchaeological aspects of food production,processing and consumption
  • 2018
  • Ingår i: Social dimensions of food in the Prehistoric Balkans. - : Oxbow Books. - 9781789250800 - 9781789250817 ; , s. 278-299

    • The site Ada Tepe situated in Eastern Rhodope Mountains (South Bulgaria) represents an unique gold mining complex continuously occupied from Late Bronze Age to the Early Iron Age. The excavations of the site revealed apart of the extensive mining activities also settlement layers bearing diverse evidence on the ancient food supply of the gold mining complex. As food represents a basic human need and cultural and technological innovations related with the metallurgy often influenced the subsistence and caused shifts in diet of the ancient population. In this paper we would like to explore such changes and shifts based on the available archaeological and archaeobotanical evidence from Ada Tepe. To achieve this the ceramic inventory of the found buildings is evaluated in terms of their meaning for food preparation and consumption. This evidence is crosschecked with the archaeobotanical evidence of disposed at the archaeological structures remains of cultivated plants, processed plant products (like porridge and bread remains) and such with possible imported character (like figs).
