PhD defense of Guilhem Doulcier

It is my pleasure to invite you to my PhD thesis defense titled "On the
evolution of collective-level Darwinian properties
" that will take

Monday 2nd December 2019 at 2pm
In Institut de Biologie de l’École normale supérieure,
46 Rue d’Ulm, Salle Favard (Ground floor, on the right)

The defense will be in english and will be followed by the customary
"pôt de thèse" in the cafétéria on the same floor.


Life has a nested structure where lower level entities are embedded in
higher level collectives (genes in chromosomes, organelles in cells,
cells in organisms, organisms in eusocial groups). All levels are
subject to evolution by natural selection. This arises from the fact
that at each level the focal entities are Darwinian, that is, they are
discrete and vary one to another, they replicate and give rise to
offspring that resemble parental types. The emergence of a new level of
organisation is a relatively rare event in the history of life, and
requires the de novo evolution of level-specific properties that
allow the new level of organisation to participate directly in the
process of evolution by natural selection. In this manuscript I explore,
using mathematical models, the idea that Darwinian properties can be
exogenously imposed (scaffolded) by the environment. I show how natural
selection can build upon those scaffolded properties to promote the
emergence of endogenous traits underpinning collective-level
reproduction and heredity.

The jury is composed of:

Hélène Morlon (IBENS, president), Sylvain Gandon (CEFE, reviewer),
Joachim Krug (University of Cologne, reviewer), Guillaume Martin (ISEM),
Paul B. Rainey (ESPCI/MPI, supervisor), Silvia De Monte (IBENS/MPI,
supervisor), Amaury Lambert (Sorbonne Université, advisor) and Philippe
Nghe (ESPCI, guest).
