Laura EME The origin(s) of eukaryotes

invitée par Amaury LAMBERT - Section Écologie et Biologie de l’Évolution

12h

Le séminaire de Laura EME (CNRS, Université Paris-Saclay) aura lieu dans la salle Favard, IBENS 46 rue d’Ulm 75005 Paris

The origin of the eukaryotic cell remains one of the most contentious puzzles in evolutionary biology. It is now clear that eukaryotic cells represent hybrid organisms : they exhibit a mixture of archaeal and bacterial features, as well as a vast number of eukaryotic-specific ones. Here, I will provide a brief historical assessment of our understanding of the Tree of Life. I will examine how recent results from the field of archaeal research allowed us to tackle some of the main questions regarding the origin of eukaryotes and which issues remain to be investigated.
