In this video, we investigate evolution–extinction dynamics using statistical physics
methods. We first study the impact of different parameters, such as the number of offspring and the death probability, on the behavior of a population during its evolution. We then focus on the evolution of yeasts and bacteria under external stress. Using these two approaches, we establish a link between numerical simulations and experimental results, and we highlight the different parameters of interest and the resulting behaviors.
This video is mainly based on the following studies:
• King DM, Scott AD, Bahar S. 2017 Multiple phase transitions in an agent-based
evolutionary model with neutral fitness.R. Soc. open sci. 4: 170005.

• Ordway SW, King DM, Friend D, Noto C, Phu S, Huelskamp H, Inglis RF, Olivas W, Bahar
S. 2020 Phase transition behaviour in yeast and bacterial populations under stress. R.
