Hello, this talk is about the evolution of CSS. Last year, it was about 25 years ago that the first proposals were being discussed. That’s a long time. And there is a lot of interesting history to go through there. Before we do that, we’ll go into evolution itself. And I’ll look at some of the work of Charles Darwin who famously published the work “On the Origin of Species… …by Means of Natural Selection.” I ended up reading this when I was at uni, I was late signing up for different courses for when it was doing my degree and I had no choice but to pick this course, that kind of consisted of reading the full works of Darwin and kind of studying evolutionary theory and some other people of his time.
