EGCE focuses on evolution and biodiversity. It adopts a multidisciplinary approach involving genomics, genetics and ecology at various levels, from genomes to species and even to communities. Different aspects of evolution are studied: adaptation, speciation, interaction between genomes and the environment, interactions between species within ecosystems and, at individual level, behavior or genome plasticity. These themes run through the activities of all the groups.
EGCE is composed of seven groups:

– Gene networks, development and evolution (RESGEN), leader Didier Casane

– Genetic interactions and invasive genes in populations (IGGIPOP), leader Aurélie Hua-Van

– Polyploidy, architecture and genome complexity (POLYGNOME), leader Nicolas Pollet

– Cognition, reproduction and adaptation in bees (EVOLBEE), leader Jean-Christophe Sandoz

– Pheromones, food, chemioreception and sexual selection (PACS), leader Frédéric Marion-Poll

– Diversity, ecology and evolution of tropical insects (DEEIT), leader Laure Kaiser-Arnaud

– Evolution and plasticity of cognitive capacities (EPCC), leader Frédéric Méry.


EGCE also has 4 technical services (Sequencing, Genotyping, Imaging, Animal breeding services).
EGCE coordinates and takes part in several national and international projects funded by organizations, such as ANR (National Research Agency), ATIPE (support for young scientists) and the European Commission. EGCE is a member of the Excellency laboratory BASC (Biodiversity, Agroecosystems, society, Climate).

LEGS, now EGCE, has been a driving force in the creation of the Institute of Diversity, Ecology and Evolution of the living world (IDEEV), together with DEEIT, the IRD072 team, the Ecology, Systematics and Evolution laboratory in Orsay directed by Jane Lecomte, and the Moulon, Quantitative genetics and Evolution directed by Olivier Martin. IDEEV was officially set up in January 2010 and brings together 30 groups with 250 people working on evolution in the Gif-sur-Yvette/Orsay area. IDEEV aims to develop into a scientific center of excellence recognized nationally and internationally by both students and institutions. Another aim is to create synergy between its various groups. IDEEV is taking over the work of the EVO-SUD network. In the near future, IDEEV may evolve into an Institute with its own premises and personnel.


LEGS professors and lecturers teach at various levels (Degree courses and Masters) in various fields related to evolution and biodiversity: animal biology, developmental biology, genetics, population genetics, evolution and ecology. Several research scientists also give seminars for Master 2 students on subjects related to their work.
