write a short R-scriipt that I can run that will clearly answer the following questions:
1. What is the distribution of genus sizes in birds? (1 mark)
2. What is the distribution of crown & stem ages (2 marks)
3. Which measure of genus age best predicts species richness – crown or stem age? (you might have to look up those terms!) (Hints: you might need to transform your data based on what answers you get for 1 and 2; there are also several commands you used in tutorial that can be used to answer that “predicts” question) (2 marks)
And, extra bonus mark: why might you get the answer you do in 3? (#this will be a comment, not a specific call to R! Hint: think about both speciation and extinction…)
