Diversité de l’Orge (Hordeum vulgare L.) dans le Nord-Ouest du Bassin Méditerranéen occidental depuis 8 millénaires d’après l’analyse morphométrique des caryopses archéologiques
International audience; Le Néolithique voit la domestication de l'Orge au Proche-Orient et sa diffusion progressive jusque dans l'ouest du Bassin Méditerranéen. Elle y représente depuis une céréale majeure des systèmes agraires. Deux sous-espèces coexistent, Orge à 2 rangs (H. v. subsp.distichum) et à 6 rangs (H. v. subsp.vulgare), subdivisées en formes nues et vêtues, en lien avec des usages et caractéristiques agronomiques variés.Les dynamiques passées de cette diversité sont peu connues car les approches paléogénétiques qui permettraient de les appréhender sont fortement limitées par la carbonisation qui, tout en assurant la conservation de la plupart des grains archéologiques, détruit l…
Correction for Frantz et al., Ancient pigs reveal a near-complete genomic turnover following their introduction to Europe
Significance Archaeological evidence indicates that domestic pigs arrived in Europe, alongside farmers from the Near East ∼8,500 y ago, yet mitochondrial genomes of modern European pigs are derived from European wild boars. To address this conundrum, we obtained mitochondrial and nuclear data from modern and ancient Near Eastern and European pigs. Our analyses indicate that, aside from a coat color gene, most Near Eastern ancestry in the genomes of European domestic pigs disappeared over 3,000 y as a result of interbreeding with local wild boars. This implies that pigs were not domesticated independently in Europe, yet the first 2,500 y of human-mediated selection applied by Near Eastern Ne…
Ancient pigs reveal a near-complete genomic turnover following their introduction to Europe
International audience; Archaeological evidence indicates that pig domestication had begun by ∼10,500 y before the present (BP) in the Near East, and mitochondrial DNA (mtDNA) suggests that pigs arrived in Europe alongside farmers ∼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 Euro-pean 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 hyp…
Pig domestication and human-mediated dispersal in western Eurasia revealed through ancient DNA and geometric morphometrics.
Zooarcheological evidence suggests that pigs were domesticated in Southwest Asia ∼8,500 BC. They then spread across the Middle and Near East and westward into Europe alongside early agriculturalists. European pigs were either domesticated independently or more likely appeared so as a result of admixture between introduced pigs and European wild boar. As a result, European wild boar mtDNA lineages replaced Near Eastern/Anatolian mtDNA signatures in Europe and subsequently replaced indigenous domestic pig lineages in Anatolia. The specific details of these processes, however, remain unknown. To address questions related to early pig domestication, dispersal, and turnover in the Near East, we …
