Thank you for your comment! In my posts I usually try to make things understandable as much as possible for people who do not have formal education in biology, because I think that understanding evolution is very difficult for most people (even for biologists it's not easy!). In this post, I tried to make an introduction for next posts, where I will explain things on higher level and in more detail. So, I would say that this series of posts is meant for all people who want to learn something about evolution biology, and do not have formal education in biology. For scientists who are working in field of evolution biology, this is too basic.
