Séminaire du Lundi 23 fevrier

Les séminaires du lundi reprennent, ce lundi 23 février, c’est Allowen Evin qui a rejoint l’ISEM cette année, qui nous parlera de: « Domestication, sélection, diffusion et changements morphologiques chez le Cochon du Néolithique à l’actuel: l’apport des approches combinées de morphométrie géométrique et ADN ancien »

à 11h Salle Louis Thaler, ISEM bât 22 2ième étage, ISEM, Université Montpellier

Résumé: Current evidence suggests that pigs were first domesticated in Eastern Anatolia during the ninth millennium cal BC before dispersing into Europe with Early Neolithic farmers from the beginning of the seventh millennium. The great diversity in domestic animals and plants that exists today bears testament to the profound changes that domestication has induced in their ancestral wild forms over the last millennia. Domestication is a complex evolutionary process in which wild organisms are moved to new anthropogenic environments. Although genetics are significantly improving our understanding of domestication and breed formation, little is still known about the associated morphological changes linked to the process itself.

Using both modern and past populations we explore the phenotypic changes linked with domestication. We analysed the modern diversity of dental morphology in modern free-living and captive wild, wild x domestic hybrid, domestic and insular Sus scrofa populations using geometric morphometric approaches.

In order to track the history of domestic pig lineages in the West Palearctic from the Neolithic to modern times, we combined geometric morphometric and aDNA analyses.
