here's the material for today's class (pdf of the class and 3 articles, i.e., Johanssen 1911, Sarkar 2005 and Vecchi 2019). With the following entry already suggested in the last email (https://plato.stanford.edu/entries/gene/) it should be enough to understand the presentation. I will also upload this material on Fenix. 

As I said, we should organise a way to have a whassupp chat whenever you have digested this material. Let me know what is best for you, perhaps after discussing the issue between you and coming up with a few options. For the people who don't want to chat and won't have time during the to-be-decided slot, email is always perfect.
