Statistical Physics of Evolution

Statistical Physics and Complexity Group meeting

Statistical Physics of Evolution

Event details

In this talk, I will discuss the analogies between evolution and statistical physics. For example, the sites in a gene can be seen as the degrees of freedom in statistical physics, such as positions and momenta of particles in a gas. These genes will mutate and evolve and eventually reach a maximum in "free fitness", which is equivalent to the minimization of free energy in statistical physics. I will mostly follow the work of Sella and Hirsch [1]. If time permits, I will also discuss the role ergodicity plays in understanding evolutionary dynamics [2].
