Assessing the transition to agriculture in Western Anatolia and the Balkans using a spatially-explicit computer simulation approach
This project aims at investigating the origins of one of the most important economic and demographic event which occurred in Europe: the Neolithic transition.
- Did humans migrated (along with their domesticated animals) into new lands during the establishment of the Neolithic in western Anatolia and south-eastern Europe around 9,000 years ago ?
- Did Mesolithic hunter-gatherers adopt farming when they were in contact with migrant Neolithic populations ?
The focus is made on the Anatolia and the Balkans which constitutes a key staging area for the further spread of the Neolithic culture through Europe since 7.000 BC. Although detailed chronologies of Neolithisation exist for individual regions, the mode and tempo of the development of the Neolithic in the area remains problematic and a precise and comprehensive theory is still needed for the entire area between central Anatolia and central Europe.
Our project aims at investigating the processes by which the Neolithic culture diffused from Western Anatolia to the Balkans by using an inter-disciplinary model-based computer simulation approach. The computer simulation approach offers the advantage of merging information from different fields in the model, possibly prehistoric archaeology, landscape archaeology, zooarchaeology, palaeogeography, linguistics and genetics.
- To what extent the genetic pool of Europeans has been modified by the arrival of farming ?
- What was the degree of cultural transmission between hunter-gatherers and farming communities?
This inter-disciplinary research plan is strengthened by the integration of our lab within the "BEAN" Marie Curie international training network (ITN), financially supported by the European Union. In particular, close interactions with archaeologists and laboratories specialized in ancient DNA extraction are promoted by this international research network and allows us to develop realistic settlement scenarios for the Neolithic of Anatolia and to dispose of invaluable sources of genetics information.
Powerful computer clusters together with complex modelling/simulation procedures in link with genetic data and geographic information (GIS).
Most recent statistical methods for population genetics analyses and parameter estimation, such as the Approximate Bayesian Computation (ABC) approach.
Modern and ancient DNA samples
Combined analyse of DNA sequences from contemporary and ancient human populations generated using the last molecular technologies such as next generation sequencing (NGS).
International Inter-disciplinary network
This project belongs to the BEAN network, whose aim is to educate a new generation of researchers that will be able to combine the important aspects of various fields while developing specialized skills in their particular scientific discipline.
