The proposed themes are the result of the fusion of projects developed by the different team members. The integration of these themes in one team reflects a common global objective, a striking resemblance in the study scale and in the chosen approaches, and interactions that are being formalised.

The global objective is to better understand how the different components of the genome act in populations and what are the consequences on genome evolution, its evolvability, and phenotypes that arise.

Natural selection, mutations and genetic drift are major driving forces of populations and species evolution. Natural selection acts at the phenotype level, which is itself dependant on the interactions between genotype and environment. Inside the genome, the environment can be assimilated with the epigenetic status, the genotype being represented by the genes and their interactions (epistasy). Hence, it is at the genome level but in the context of population that the team project lies.
Topics that interest us mostly are evolution and the dynamics of different genetic systems in populations and ultimately at the species scale, the interactions in these systems, epigenetics influence, and the consequences at the phenotypic and adaptive level. Two types of genetic systems are studied: 1) Complex genetic systems, which evolution is still difficult to understand.  They are, on the one hand, gene sets controlling quantitative characteristics, and also  gene networks submitted to epistatic effects or of canalisation, or further on the set of sequences present on a chromosome. 2) Genetic system so called “egoistic systems” which can amplify them-selves in population more rapidly or more efficiently than possible by the mendeleian segregation or darwinian selection. Among them are disruptors of segregation that promote their own transmission at the expense of alternate alleles, or the transposable elements, which replicate faster than the host genome and use sexual reproduction to invade populations.

The various projects combine in variable amount experimental , bio-informatic and theoretical approaches. The experimental part includes experimental evolution and natural populations analysis combined with morphological analysis, transcriptomics or genomics. Our main model is Drosophila (D. melanogaster and D. simulans). The bio-informatics  part is aimed at a better understanding of sequences evolution at the scale of genomes and populations.
