"Evolution of eusociality"

Eusociality is an advanced form of social organization, where some individuals reduce their reproductive potential to raise the offspring of others. Eusociality is rare but hugely successful: only about 2% of insect species are eusocial, but they represent 50% of insect biomass. I will present a theory for the origin of eusociality. In the solitary life style all offspring leave to reproduce. In the eusocial life style some offspring stay and help raise further offspring. A standard natural selection analysis determines which of those two reproductive strategies wins for a given ecology. The model makes simple and testable predictions. I will also discuss the limitations of inclusive fitness theory showing that it is a particular accounting method that can be used in special cases, but not in general. Inclusive fitness is to a large extent a conceptual mistake that arises from the unsuccessful attempt to find a universal maximization principle in evolution.

"Evolutionary Dynamics"

I will give an overview of simple stochastic models of evolutionary dynamics. The topics of my talk include: constant selection on graphs; suppressors and amplifiers of selection; the isothermal theorem; games in finite populations, on graphs, in phenotype space and on sets; the 1/3 rule for games in well mixed populations and on graphs; the replicator equation on graphs; Antal’s formula for n-strategy games in well-mixed populations; Tarnita’s sigma theorem for structured populations and its extension to n-strategy games.

"The Evolution of Cooperation: Why We Need Each Other to Succeed"

During his upcoming Public Lecture, evolutionary biologist Martin Nowak, author of the best-selling book SuperCooperators, will share his cutting-edge research on the mysteries of cooperation. According to Nowak, many problems that challenge us today can be traced back to a tension between what is good and desirable for society as a whole and what is good and desirable for an individual. This conflict is illustrated in global problems such as climate change, pollution, hunger, and overpopulation. Nowak argues that cooperation—not competition—is the key to the evolution of complexity.


Université de Montréal, Pavillon Jean-Coutu, 2940, chemin de Polytechnique, salle S1-151


La conférence sera suivie d'un vin d'honneur à l'Agora Goodman.
