Missions

Human mobility is a key factor for the spread of genes and cultures, but it affects them in different ways. While genes spread exclusively by movements of people, cultural traits can spread independently and over long distances by cultural interaction. The goal of this postdoctoral project is to explore gene-culture co-evolution in Europe during the transition to farming by using a novel approach that will jointly estimate human mobility and material culture diffusion from both a genetic and archaeological perspectives.
The project is based on the assumption that mobile societies will be characterized by comparatively low isolation by distance, while less mobile groups will be geographically structured. It is also based on the widely accepted idea that similarities in material culture result from repeated interactions between individuals and groups, favored by individual mobility, exchange of goods, social information, technological knowledge and symbolic items. In other words, the more the material culture is similar, the tighter are the links between groups.
Attempts to cross genetic data and cultural data are not numerous. In this project we wish to analyze genetic and archaeological data jointly and with comparable methodologies. We will focus on Europe at the dawn of agriculture, circa 7500 years ago, a time period and region for which foragers and farmers genetic data, and data on their material culture, are available. The genetic dataset comprises hundreds of published samples from all over Europe for the target period, including genome-wide as well as mitochondrial and Y-chromosome data. The archaeological dataset is composed of an updated georeferenced database of personal ornaments produced by the last hunter-gatherers and the first farmers in Europe covering 48 archaeological cultures and recording hundreds of different bead types from more than a thousand burials and archaeological levels distributed throughout Europe.
The combined analysis of these data sets will allow to address issues such as the degree of similarity between regions in processes of genetic and cultural admixture, document sources and proportions of hunter-gatherer ancestry, discuss whether personal ornaments circulation is more related to women or men mobility. It should also allow investigating whether cultural boundaries limited gene flows and slowed down the Neolithic spread in some areas.

Activities

The candidate will have a primary role in the processing and management of genomic data (both ancient and modern), as well as the development of methods to jointly study the archaeological and genetic data. He/she will also contribute to the organization of an international meeting on culture/gene co-evolution at the end of the project.

Skills

The ideal candidate will have computational background (knowledge of R and Python/Perl programming languages), strong skills in bioinformatics and biostatistics to handle and analyze genomic data. He/she will also have a strong population genetics background (with a particular focus on demographic modelling), and a deep interest in cultural evolution and archaeology.
We are seeking for candidates who can communicate and write in English although fluent English is not mandatory. Applicants should have a PhD degree or demonstrate they have submitted their PhD dissertation for discussion.

Work Context

The postdoc will be based at the PACEA laboratory of the Bordeaux University and will collaborate with archaeologists (S. Rigaud and F. d'Errico), paleogeneticists based in the same laboratory (MF Deguilloux, M. Rivollat) and population geneticists from the University of Ferrara (G. Barbujani, S. Ghirotto). The postdoc will be a team member of the CNRS Momentum project led by S. Rigaud titled Symboling and neighboring at the dawn of Agriculture. He/she will also benefit from an ongoing collaboration with researchers involved in the ANR-DFG project INTERACT “Human interactions during the Mesolithic-Neolithic transition in Western Europe: The dual perspectives of cultural and biological exchanges” (PI W. Haak & MF. Deguilloux).
The successful candidate will receive financial support for attending international meetings, preparing publications, and covering expenses to fund short stays at the University of Ferrara (Italy).
