EVOSHEEP project: Documenting morphological diversity of early sheep 'breeds' in Southwest Asian societies (6th - 1rst millennia BC) using 3D geometric morphometric of appendicular bones
Résumé
The EVOSHEEP project focuses on the complex history of early sheep (Ovis aries) husbandry in Southwest Asia between the Late Neolithic and Late Bronze Age using a multi proxy approach (morphometrics, genetics, iconography) to identify the biological and anthropological components behind the emergence and development of early sheep breeds.
One of the challenges in this approach is to be able to disentangle the impact of anthropogenic selective pressure from ecological conditions on the skeletal morphology of sheep on a large scale. As a first step towards this understanding, we first explored the extent of morphology diversity and change in domestic sheep populations across southwestern Asia over the last 8,000 years.
Using the recent development in virtual morphometrics on distal humerus, calcaneum and astragalus bones, this paper will present our latest thoughts from the comparative study of ancient sheep from forty archaeological sites across Syria, Lebanon, Iraq, Azerbaijan, Georgia and Iran between the 6th and the 1st millennium BC with current traditional breeds of sheep from Middle East and Eastern Africa whose husbandry practices are well documented.
