A couple of years ago, I returned home, a bit drunk, and started randomly clicking on wikipedia articles. I ended up reading about muskox. My first response was surprise and excitement by it's severe ugliness. Several years later, during my MSc studies, I attended Computational Biology and part of this course was to do a project with an animal of our choice, ask a question about it and answer using data. So, I decided to choose "muskox" and the question to ask was, "where does all this ugliness comes from?". The study is a bit technical but the answer very interesting.
