Hi, i really like your series. This subject is very interesting. I don't know if you would consider doing an even more basic introduction to mutation biases? Coming from an undergrad, I understand the importance of using the right words for new ideas and not falling in the neo-darwinian paradigm vocabulary. But, I must admit it took me quite a lot of reading of blog and listening before having a «correct» understanding of the subject. I think it could benefit newcomer and help spreading the ideas!
